Abstract

Although many types of wounds are easily treated, some require

specialized expertise in order to resolve or treat the primary cause and

to prevent additional wounds. Clinicians who opt to specialize in wound

care provide an important skillset to patients suffering from chronic or

acute injury, disease, or medical treatment. Often, a holistic approach

is adopted, with coordination of health team efforts to ensure that all

aspects of a patient's health are considered during the course of initial

and ongoing wound care management. Wound care clinicians also

serve as a resource to prepare the patient to continue care at home.

Introduction

Assessment is the first step in the management of a wound. It should

be performed during the initial stages, such as when a patient seeks

care for treatment of a wound or when a clinician or caregiver

discovers that a wound has developed. Continual assessment is

important throughout the treatment process to discern how well the

wound is healing and to determine if treatment measures are being

effective. This course discusses key aspects of the assessment

process, preparation of the wound area for treatment, and basic

wound dressing types to manage exudate and to facilitate healing.

Wound Assessment

Wound assessment involves ongoing observation whereby a clinician

inspects the wound and notes characteristics present. During

observation of the wound, the clinician takes the time to identify the

overall appearance, its approximate size, and whether any other tissue

or drainage is present, such as granulation tissue or slough. Other

characteristics of the wound that a clinician may determine upon

inspection include the approximate size and depth of the wound,

where it is located on the body, whether tunneling or undermining are

present, what type of drainage is present, if any, and if the skin or

tissue is infected or necrotic.

The clinician may also measure the size and depth of the wound by

examining its width and length. To measure the wound, the clinician

uses a flexible tape measure and measures the width and length at the

longest portions of the wound; this information is then documented in

the patient’s chart. The depth of the wound can be measured by

inserting a cotton-tipped applicator and very carefully touching the

6

base of the wound. This method may be necessary if the wound is

unstageable or the clinician is unable to see if underlying structures,

such as fascia or muscle tissue, are exposed at the base of the wound.

When tunneling is evident, a cotton-tipped applicator or a gloved

finger can be used to assess the length and the area of tunneling. For

instance, if tunneling appears from one side of the wound to an

underlying area, the clinician can use this method to measure how

deep the tunneling extends. If infection is apparent, a sample may be

collected for a wound culture during the assessment and measuring

process.

The clinician should also talk with the patient and obtain subjective

information about the wound and the patient’s medical history.

Information about how the wound developed, how long it has been

present, and whether the patient has taken measures to treat the

wound are important aspects to note and document in the initial

assessment. The nurse should also determine if the patient has any

underlying conditions that would contribute to wound development or

delayed wound healing, such as diabetes, malnutrition, or immobility.

The patient’s report of pain from the wound is also important to note.

A wound may cause a range of reactions from patients, from mild

discomfort to excruciating pain. An infected wound may cause pain

when inflammation is present as well. The clinician should assess the

patient’s level of pain by asking the patient to identify pain intensity

and describe the type of pain present. Treating pain associated with

the wound is part of overall wound care management.8

Foreign Bodies

A foreign body is an object in the skin that is not supposed to be part

of the wound. A foreign body may be in a chronic wound if the ulcer

was exposed to some sort of material or object that inadvertently

became embedded in the wound. An example of this might be when a

patient with a healing diabetic ulcer on the foot walks barefoot without

a covering on the wound and an object is embedded in the wound.

A foreign body may also enter the skin as part of the cause of the

wound. An accident or injury that causes the wound may leave

retained objects associated with the injury causing mechanism inside

the skin as part of the wound. When the objects are not found and

removed, the body recognizes them as foreign, thereby starting the

inflammatory process in response. Foreign objects that become

embedded in the skin can come from any number of items and can

range from shards of glass, pieces of wood from splinters, dirt, sand,

rocks, or various other materials.

Assessment of foreign bodies must be part of the initial examination of

the wound. If the object is not removed right away, the wounded area

can become reddened and the tissue can become inflamed. If an

infection does not develop in spite of the foreign body, the wound may

start to heal around the object, leaving a lump or nodule under the

skin that is very painful.

An article in The Nurse Practitioner: The American Journal of Primary

Healthcare describes other factors that can indicate if a foreign body is

present in a wound, which affects its healing process. The wound may

have continuous purulent drainage or may develop an abscess, which

Page 8: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

8

indicate that infection has developed around the item. If a patient is

allergic to a substance that enters the wound, the body may respond

with substantial inflammation, itching, and skin breakdown. A wound

with a retained fragment that has not been found and that develops an

infection may not respond well to antibiotic therapy as it normally

should.69

Assessment for a foreign body within a wound may be demonstrated

as increased patient pain with skin palpation, decreased circulation,

and diminished sensation in the region distal to the wound. The object,

if large enough, may compress the blood vessels or nerves and

ultimately affect sensation and blood flow, causing pain, numbness,

tingling, pallor, and poor peripheral pulses.69

Identification of a foreign object may require diagnostic tests, such as

an X-Ray or MRI. The type of test ordered depends on the patient’s

history and physical, the potential factors of what the foreign object

might be, and whether or not the object is visible through examination

of the wound. If the practitioner suspects a foreign object in the

wound but cannot visualize it, he or she should not blindly probe the

wound to search for it to be removed, as this can cause further trauma

to the tissue and could lead to increased bleeding or infection.

When the object is identified and should be removed, removal often

requires exposing the wound bed, if possible, and irrigating the wound

with normal saline. The clinician may then pull the object from the

wound if it is accessible. In some cases, a foreign object cannot be

removed without significant tissue trauma, in which case, surgical

intervention is necessary. When working with a wound that contains a

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

9

foreign object, pain medication and comfort care for the patient is

necessary, as the process can be quite painful and can produce

significant anxiety.

Once the object has been removed, the wound should be cleaned and

covered with a dressing for further protection. The clinician may order

antibiotic ointment or a specialized dressing to protect the wound. The

clinician should monitor the wound closely during the period following

foreign body extraction, as the wound can still develop an infection

after exposure to the item. Frequent assessment for skin changes,

including an increase in drainage, skin redness, inflammation, and

increased pain can all indicate a developing infection after the foreign

object has been removed. Further treatments with regular dressing

changes, cleansing, and balance of moisture are also necessary to

promote healing long after the object is out of the wound.

Sensation

Some patients, particularly those with neuropathy associated with

diabetes, have decreased sensation in the lower extremities. When this

occurs, the patient may be unable to sense an injury to the skin or

that breakdown is happening at all unless he or she checks the feet

and legs on a regular basis. Assessment of sensation is important to

determine if the patient is at risk of skin breakdown because of

decreased feeling in the lower extremities.

One of the most common forms of testing for sensation is by using the

Semmes-Weinstein monofilament test. To perform the test, the

patient’s feet are exposed and a 5.07 monofilament is used to press

against the patient’s skin for one second at a time. Without watching

Page 10: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

10

what the clinician is doing, the patient tells the clinician when he or

she feels the filament against the skin.

The monofilament exerts approximately 10g of pressure against the

skin, making this a useful test for determining loss of sensation.104 The

clinician should press the monofilament into various locations in the

lower legs and feet, avoiding calloused or thickened areas of skin. A

patient who cannot consistently detect the monofilament during the

test should receive further evaluation for decreased sensation due to

neuropathy.

The monofilament test should be combined with checking the foot for

signs of injury, ulceration, decreased blood flow, or decreased

sensation, as well as checking the patient’s history for reports of

decreased sensation, numbness, tingling, pain, or decreased

movement in the lower extremities.

Blood Flow

Assessment of blood flow to the affected area is combined with

information gained from the patient’s history description of the cause

of the wound. Wounds are significantly impacted by proper blood flow;

decreased blood flow to an area results in deoxygenation of tissues

and increased risk of skin and tissue breakdown. It is therefore

important that part of the focused exam include assessment of blood

flow to the area.

Arterial insufficiency leads to ulcers that most commonly develop in

the lower extremities, so when a patient presents with a wound and

has a condition that impacts circulation, the clinician should assess for

Page 11: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

11

adequate blood flow to the affected area. This includes assessing and

noting skin color, such as whether it is pink and looking healthy or if it

is pale or cyanotic, as well as patterns of hair growth in the lower

extremities. Assessment of capillary refill can be performed in various

areas by lightly depressing an area of the skin with a finger to cause it

to blanch and then counting how long it takes for blood to return to

the area and for color to be restored.

The clinician may also assess pulses, both proximal and distal to the

wound site. Assessing pulses in various locations also provides a more

comprehensive view of the patient’s circulatory status. For example, if

a patient presents with a wound on the lower leg on the calf, the

clinician may assess the popliteal pulse behind the knee as well as the

dorsalis pedis and posterior tibial pulses in the ankle and foot. Use of a

doppler to assess pulse may be necessary if it cannot be found

through palpation.

Signs and symptoms associated with peripheral artery disease, such as

poor skin color, pain in the lower legs, and intermittent claudication,

can also appear when a patient has arterial insufficiency and should be

assessed when the patient presents with a wound that has developed

from diminished arterial circulation.

Erythema, or redness of the skin and mucous membranes, occurs

when the capillaries near the surface of the skin dilate and blood flow

is increased to an affected area. Erythema that is blanchable should

briefly turn white when the skin is compressed and then return to a

red color. An early wound, such as a stage I pressure ulcer, occurs as

non-blanchable erythema, in which the skin does not change color

Page 12: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

12

when it is compressed slightly during the assessment. When skin has

non-blanchable erythema present, it is a sign that tissue damage has

occurred under the surface, even if the outer layers of skin remain

intact.8

When assessing erythema, the clinician should note the size of the

reddened area, measuring it, if possible. If the area blanches when

pressed and then fills in with redness again (which is a test of capillary

refill) the clinician should note the length of time it takes for color to

return. Capillary refill should be brief; the longer it takes for the tissue

to return to its color after finger pressure, the greater the risk of

damage to the skin.8 A slow return of color to the affected area

indicates that blood flow is sluggish and the skin could become

ischemic. If the clinician provides an early assessment and catches a

situation where non-blanchable erythema is present, the condition

may still be reversed before permanent damage ensues.

It may be difficult to assess areas of erythema among patients who

have dark skin. In these cases, skin may appear to have purple

undertones and the skin surface may be shiny and firm. The clinician

can use a direct light over the affected area for assessment and look

for other signs of injury beyond erythema, such as tissue swelling and

warmth.8

Development Of A Treatment Plan

The development of wounds within the hospital environment is an

unacceptable complication that can occur with some patients who are

at high risk. Some patients, particularly those who are immobile and

require multiple devices for their care, such as ventilators and

Page 13: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

13

hemodynamic monitoring, are at greater risk of wounds developing in

the healthcare environment. The development of severe wounds such

as stage III and stage IV pressure ulcers that occur in a healthcare

facility has actually been classified as a never event. In 2008, the

Centers for Medicare and Medicaid Services announced that it would

no longer pay for treatment measures for pressure ulcers that have

developed while patients were in the hospital.3 Beyond the obvious

effects of preventing pain and infection as a result of wounds, this

statement is another form of evidence that prevention and treatment

of wounds is important to avoid costly consequences for the healthcare

facility.

When a wound is found to have developed, the wound must undergo

cleansing and evaluated for a method of clearing away debris and/or

unviable tissue so that healthy tissue can form. The following section

outlines wound care options that may be found in the patient’s

treatment plan.

Wound Cleansing

Wound cleansing is a routine

procedure that reduces the amount

of debris and bacteria that can build

up in the wound. Wound cleansing

should be performed regularly when

a clinician changes the wound

dressing and both before and after

wound debridement. If a skin graft

has been placed, the clinician should

cleanse the skin around the graft but

Page 14: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

14

should not disturb the graft itself.20

Cleansing is done gently, both for comfort of the patient, as the wound

can be extremely painful, and to prevent further trauma to the wound.

It should be noted that trauma could occur during cleansing both by

physical and chemical means. Vigorous scrubbing of a wound can

cause physical trauma, but gentle application of a harsh chemical to

the wound can also cause tissue trauma. The type of cleanser and

method of administration is determined by the health clinician and

typically considers such factors as the amount of necrotic tissue

present, the amount and type of exudate present, and the area of the

body affected by the wound. When applying a cleanser and cleaning

the wound, the clinician should stimulate the tissue enough that debris

and excess drainage is removed but that the healthy, growing tissue is

not disturbed.

The clinician applies the cleanser to the wound, which is designed to

break up debris and to collect drainage, which is then rinsed away.

While commercial cleansers that contain additives effective for

cleansing may be ordered, normal saline has also been effectively used

as part of wound cleaning. When normal saline is added to a wound

bed with the correct amount of pressure, it can lift and wash away

wound debris and exudate without damaging the wound. Alternatively,

wound cleansers that contain antimicrobial agents, such as hydrogen

peroxide or povidone-iodine can cause cytotoxicity and could more

likely damage the tissue instead of adequately cleaning it.20,21

Once a wound has been cleaned, the clinician should assess for

whether odor is present in the wound, which can indicate infection.

Page 15: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

15

Odor should be assessed after wound cleansing, as the presence of

odor before the wound is cleaned could be caused by dead tissue that

must be removed but that is not infecting the wound. When odor is

present after a wound has been cleaned, the clinician should assess

further for other signs of infection.

If odor or other signs of infection are present in the wound, the patient

may benefit from a short-term cleansing regimen of antimicrobial

wound cleansing products, despite their potential cytotoxicity.

Examples of these types of agents include Dakin’s solution, Hibiclens,

and hydrogen peroxide. These agents should not be used on clean

wounds with regular cleansing, but their application to contaminated

or infected wounds may be considered on a case-by-case basis.20

Debridement

Debridement is the process of removing dead tissue from the wound in

order to promote new growth, reduce infection, and promote wound

healing. The wound bed should be evaluated during the assessment

phase and the clinician should understand the various types of

drainage and tissue that indicate growth and healing, particularly

before embarking on the debridement process, in which healthy new

growth could otherwise be accidentally removed.

Necrotic tissue is one element that should be removed from the wound

during debridement. When moist, necrotic tissue may appear as yellow

or gray; and, when dry, necrotic tissue has the appearance of black,

tough eschar that may be thick or leathery. An area of necrotic tissue

may be covering an infection or a collection of fluid. When the necrotic

tissue is removed with debridement, the underlying area is exposed,

Page 16: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

16

which may cause fluid drainage or could reveal an infection. Eschar

differs from a scab, however, and the clinician should be familiar with

the differences in appearance and the make-up of these two wound

components.

While eschar consists of necrotic skin that has hardened into a tough

layer, a scab is made up of dried blood and exudate from the wound. A

scab may or may not need to be removed during the healing process,

but the clinician should understand that the terms eschar and scab are

not interchangeable and they should not be treated as such. A scab is

not associated with tissue necrosis and it is not dead tissue.22

Before starting the process of debridement, the clinician should be able

to identify necrotic tissue, as compared to granulation or epithelial

tissue, which indicates that the wound is healing. As stated, necrotic

tissue is tough and black. Fibrin is another element that must be

removed as part of debridement; it appears as white, yellow or gray in

color and might look stringy or rubbery. Slough is also yellow or gray

and has a similar, stringy texture.

Necrotic tissue must be removed through debridement when it is

present, as failure to remove it can lead to proliferation of bacteria and

increased risk of infection. A wound that contains necrotic tissue will

be unable to synthesize new tissue in a normal manner and necrotic

tissue prohibits the skin cells from communicating with each other to

form new granulation tissue.

The only exception to when eschar should be removed is when it is

found intact on a wound on the heel. The Agency for Healthcare

Page 17: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

17

Research and Quality (AHRQ) has issued guidelines that state that it is

better to leave this type of eschar in place, rather than trying to

remove it through debridement.22 The eschar must be flat and well

adhered to the heel, without evidence of surrounding edema,

sponginess, or drainage. If the eschar is found to be intact without

surrounding signs of infection or disease, it should remain in place, as

the structure of the heel does not allow the clinician to determine the

depth of the ulcer. In other words, a clinician may view a heel wound

with solid eschar covering it, but the clinician may not know if the

wound is relatively superficial or if it extends down to the connective

tissue and bone of the heel. In this case, it is safer to leave the eschar

in place if the wound is not infected.21

When this occurs, instead of removing the eschar on the heel, the

clinician should keep it in place as a method of sealing off the wound.

Skin care is still required in this area, even without debridement. The

clinician should take pressure off of the heel by elevating the area

when the patient is at rest; this method of pressure relief, called off-

loading, is the standard form of treatment in place of debridement of

this type of heel wound.22

There are several different forms of debridement. The decision of

which type to perform is based on the type of wound, the medical

clinician’s orders, and surrounding circumstances that affect the

removal of wound tissue, such as the presence of infection or

inflammation in the wound. The types of debridement that may be

used include surgical, autolytic, mechanical, enzymatic, and biological

debridement.

18

Sharp Debridement

Surgical debridement is an effective form of wound management, and

is used for some particular wounds, such as diabetic foot ulcers. It is

used with a scalpel or scissors to cut away dead tissue and is often

performed in a surgical suite, depending on the extent of the wound. A

surgeon or physician typically performs surgical debridement under

sterile conditions. Surgical debridement quickly removes the dead skin

and eschar that are covering the wound to expose the underlying

portion to heal. A surgeon, advanced practice nurse, or specially

trained RN may perform conservative sharp debridement as a method

of removing dead tissue through cutting. This type of procedure can be

performed in an operating suite or it could be done at the bedside.

Sharp debridement carries an increased risk of wound bleeding

following the procedure.22

Autolytic Debridement

Autolytic debridement uses the body’s own tissues and cells to break

down necrotic tissue for removal. Autolytic debridement utilizes the

fluid found in the wound as a healing mechanism to remove dead

tissue. The fluid within the wound contains such components as

macrophages and neutrophils that work to support the immune system

and to tackle foreign pathogens that have invaded a portion of the

body. To perform autolytic debridement, the clinician applies a

dressing over the wound to keep the wound bed moist. The fluid

released from the wound liquefies the dead tissue so that it can be

cleared away.23 Autolytic debridement is one of the most painless

forms of removing dead tissue; however, because it can take longer

when compared to some other forms of debridement, the patient may

be at a greater risk of infection with this process.

19

Mechanical Debridement

Mechanical debridement includes physical means of removing dead

skin tissue. Examples of mechanical debridement are using a force of

water to eliminate dead tissue, such as with a whirlpool; and, using

wet-to-dry dressings, and performing wound irrigation.

Using a whirlpool provides a form of mechanical debridement, as the

use of warm water with a slight pressure can soften eschar and make

it easier to remove necrotic skin. A whirlpool tub may be available at a

fixed location in a health center or it could be a portable device used to

take between patients who need this type of debridement. The

whirlpool utilizes warm water and the patient either submerges the

wounded area or his entire body into the water.

Whirlpools, when used as a form of mechanical debridement, have not

only been shown to effectively remove necrotic wound tissue, but also

to improve circulation by promoting vasodilation, reducing instances of

infection by removing exudate, and providing comfort for a patient

during the debridement process. To use, the wound care patient is

taken to the whirlpool for the number of minutes prescribed by the

physician. The temperature of the water is well controlled and a

patient with cardiovascular disease or peripheral neuropathy should

not use water with temperatures over 38°C.24 After using the whirlpool

for the prescribed time, the clinician rinses the patient’s wound with

enough vigor to remove the softened, necrotic skin and exudate from

the wound bed.

A whirlpool treatment should not be used for all wound patients, and

not everyone can tolerate time in a whirlpool for debridement. A

20

patient who is immobile may not be able to get out of bed or move

much to get to the whirlpool, even if the tank is portable. Some

patients have clinical conditions in which they do not tolerate high

water temperature or they would not be able to endure the time spent

in the water. Further, whirlpool treatment should not be performed on

certain types of wounds, such as venous insufficiency wounds. Placing

the affected extremity in a dependent position in a whirlpool when a

venous ulcer is present is not helpful; the fibrous tissue sometimes

formed in a venous ulcer is relatively unchanged by whirlpool

debridement and this form of therapy is usually not successful at

removing it.

Finally, whirlpool tubs, because they are often used for more than one

patient, may carry a risk of infection if they are not properly cleaned

and maintained. All facilities should have protocols in place for

cleaning and disinfecting whirlpool tanks, and a facility should use this

form of treatment very carefully when working with wound care

patients to prevent the development of healthcare-acquired wound

infections that are transmitted between whirlpool tanks.

Another type of mechanical debridement that can be done at the

bedside and regularly performed by the clinician is the use of wet-to-

dry dressings. This type of dressing change, while serving as a form of

mechanical debridement, has come under fire in recent years as to its

purpose and its potential for negating some of the factors associated

with wound healing. When using a wet-to-dry dressing, the clinician

places a saline-soaked piece of gauze onto the wound bed. The gauze

eventually dries and once dried, the clinician pulls it off, taking debris

Page 21: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

21

and dead tissue with it. The process is then repeated as the wound

heals; it is sometimes performed up to four times per day.

Although the process of pulling off a dry piece of gauze can be efficient

in removing eschar and dead tissue from the wound bed, this type of

debridement unfortunately also can remove healthy tissue as well,

which slows and impairs the healing process.25 It is also extremely

painful for the patient when the clinician pulls the dressing off. The

wound itself may already be painful, but then pulling off a piece of

gauze that has dried and become stuck to the wound bed can be

agonizing. Some clinicians, in an attempt to provide comfort, have

wetted the gauze before removal so that it might be less painful for

the patient, but this actually negates the process of debridement.

Wet-to-dry dressings are warranted in some situations that require

mechanical debridement and they may be ordered as such. However,

there are a number of various debridement techniques and dressings

available as treatment for wound care such that wet-to-dry dressings

are becoming less common in favor of other measures. While still

used, this type of mechanical debridement may not be the best choice

for some wound care patients.

Irrigation is a third type of mechanical debridement; like the whirlpool,

irrigation uses hydrotherapy to soften necrotic tissue and cleanse the

wound bed of debris. Irrigation involves using a syringe or catheter to

irrigate the wound at a certain level of pressure to loosen and wash

away debris and dead tissue.22 Irrigation may be performed at the

bedside by the clinician; it must be done at a pressure between 4 psi

and 15 psi in order to be effective: pressures less than 4 psi are not

Page 22: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

22

strong enough to loosen tissue and pressures greater than 15 psi have

been shown to damage healing skin and to drive debris deeper into the

tissues.

Irrigation by hand with a syringe can be performed relatively easily as

long as the clinician places a basin next to the wound to collect the

drainage and irrigant solution. This type of debridement is most

effective for wounds that are not infected or that only have minor

infections, those that do not contain significant amounts of debris, and

those that do not have thick eschar, as the pressures used with

irrigation are not high enough to loosen and remove very thick or

tough eschar.20

Another more technical form of irrigation is pulsatile lavage with

suction, which is designed to mechanically irrigate and cleanse a

wound to remove debris, exudate, and slough tissue from the wound

bed while simultaneously suctioning the fluid and output. This type of

irrigation may be more likely to stimulate granulation tissue formation

because of its action of slight pressure with irrigation combined with

negative pressure of suction. McCullogh and Kloth, in the book Wound

Healing, cited a study that showed that wound care patients who

received pulsatile lavage with suction had an over 12 percent increase

in granulation tissue formation per week when compared to 4.8

percent increase among those who used whirlpool therapy.20

Further, pulsatile lavage with suction can be used on many different

types of wounds and it is site specific, meaning a patient does not

have to have an extremity or the entire body submerged in a tub of

water to derive the benefits of debridement. Pulsatile lavage has been

Page 23: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

23

used for successful debridement of diabetic wounds, venous ulcers,

surgical wounds, pressure ulcers, and wounds that have become

infected. It can also be used on complicated wounds where tunneling

or undermining is present.20 Pulsatile lavage can be performed by a

clinician and it does not require advanced training, although it should

be done by someone who has some experience with the procedure;

however, when a patient has a significant wound, such as one that

extends to the bone or that is near a great vessel, it is better to have

an advanced practice nurse or physician perform the procedure.

Enzymatic Debridement

Enzymatic debridement is a form of topical debridement that may be

combined with other forms, such as surgical or sharp debridement.

Enzymatic debridement is done when a formulation of enzymes is

applied to the wound bed, which breaks down necrotic tissue so that it

can be removed. The process is performed once or twice daily and it

can easily be done at the bedside without excess equipment or the use

of a surgical suite. The advantages of enzymatic debridement include

its use in patients with bleeding or clotting disorders. Other forms of

debridement may increase the risk of bleeding in the wound, which

can be harmful to a patient who has difficulties with blood clotting.

Enzymatic debridement can also be used among patients who have

various types of wounds and it has been used successfully among

patients with such wounds as diabetic ulcers, burn wounds, venous

ulcers, wounds that are infected, and wounds that contain large

amounts of slough and eschar.26

To perform enzymatic debridement, the clinician first cleanses the

wound site with normal saline or with a cleansing agent. The clinician

Page 24: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

24

then applies the exogenous enzymes directly to the wound bed. If

black eschar is present, a process called cross-hatching is first

required, which involves cutting a crisscross pattern into the surface of

the eschar with a scalpel. This ensures that the enzymatic solution is

more likely to reach the wound bed under the layer of thick eschar.26

The process typically causes little pain to the patient, particularly when

compared with some other forms of debridement.

The goal of enzymatic debridement is to soften and liquefy necrotic

tissue to the point that it can be easily removed after a short time

spent with the application of enzymes. The process of cross-hatching

the eschar prior to administration may be painful for the patient, but

the process otherwise does not typically cause significant pain.

Enzymatic debriding agents are available by prescription only and may

be available through the healthcare pharmacy. Examples of enzymatic

debridement preparations include collagenase, Panafil, and papain and

urea (Accuzyme).

Biological Debridement

Perhaps one of the most interesting and oldest forms of debridement

is the use of biological substances on the wound surface to break down

and loosen debris in order for it to be quickly removed. One of the

most common forms of biological debridement is the use of medical-

grade maggots placed in the wound bed. Several sterile maggots —

the number of maggots used is determined by the size of the wound —

are placed in the wound bed and then covered with a light dressing or

gauze. The maggots sit in the wound bed and digest necrotic tissue.

Use of maggots is beneficial in that they focus on digesting necrotic

tissue only and they leave healthy tissue alone.

Page 25: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

25

After hours or days of the maggots being in the wound bed, the

covering is removed and the maggots are rinsed away. The process of

using maggots for debridement has been in use for hundreds of years

and was a relatively common form of wound debridement during the

American Civil War. Its popularity declined in the following period but

has gained interest again, starting in about the 1990s with the rise of

more and more resistant organisms. The maggots work not only by

digesting the necrotic tissue, but they also release a type of enzyme

that works to break down dead tissue in the wound, making it easier

to remove.

The practice of using medical-grade maggot as a form of biological

debridement has other benefits as well. Its use has been shown to

decrease wound odor and increase the rate of generation of

granulation tissue.27 Most patients suffer only minor discomfort with

this type of debridement; they may state that they do not notice the

maggots or only feel a slight tingling sensation. Some people, although

they do not experience much physical discomfort, instead feel

uncomfortable with the idea of using maggots in a wound bed, which

can be a barrier to this type of treatment and must be further explored

if biological debridement is to be used in a chronic wound.

There may be times when it is better for a wound not to be debrided.

As stated, the AHRQ has specified that dry heel wounds that are

covered with eschar should not be debrided because it may be difficult

to determine the depth and extent of the wound. Additionally, patients

who have severe peripheral vascular disease that significantly

compromises circulation to the area of the wound should not have

wounds debrided. Further, a condition known as dry gangrene, which

Page 26: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

26

develops as a result of poor blood flow rather than an infectious

process, is also considered a contraindication to debridement because

of the potential for infection and lack of blood flow to the affected

site.22

Moist Wound Bed and Healing

A wound requires a moist wound bed in order to best promote healing.

Moisture is necessary throughout the body for the cells to function

properly; however, moisture must be controlled and kept within a

delicate balance. In the case of a wound, the wound bed should be

kept moist but without affecting the surrounding tissues, as excess

moisture in areas outside of the wound bed can lead to maceration

and skin and tissue breakdown.

A moist wound bed is required for new granulation tissue to form in

the wound bed. As the cells migrate toward each other during healing,

they must have moisture. If the wound bed is too dry, the cells are

unable to move together to heal the wound and to close the edges. In

order for the wound to heal in a timely manner, the wound bed must

remain moist, or the wound will heal much more slowly when

compared with other wounds that are kept moist.29

The idea of keeping the wound bed moist originated in the 1960s when

Dr. George Winter, a urologist, determined that moisture was an

essential component of epithelialization and that open wounds healed

at a faster rate when kept moist.29 Prior to this time period, many

practitioners believed in keeping wounds open and/or uncovered;

today, many people still believe in keeping a wound open to air as it

heals, but this process actually negates the healing process because it

Page 27: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

27

causes the cells to dry out. Moisture is also important for keeping the

wound at an appropriate temperature that is best for healing. Finally, a

moist wound bed reduces the risk of infection, as it is necessary to

support debridement. During enzymatic or autolytic debridement, for

example, the moist wound bed supports the environment for the

process to work. In other words, application of a debridement solution,

such as that used for enzymatic debridement, will have a much more

positive effect on healing when it is applied over a moist wound bed

instead of trying to get the solution to work to debride a dry wound

bed.

The concept of wound bed preparation has been devised as a

structured approach to promoting healthy tissue within the wound bed

while supporting the effectiveness of other forms of therapy and

treatment. Preparation of the wound bed allows the clinician to

determine if there are factors that are affecting the process of wound

healing; this concept is most often used when dealing with a chronic

wound that is not healing.28 Wound bed preparations focuses on

maintaining moisture levels in the wound bed, promoting new tissue

growth, and preventing infection.

The clinician can implement the mnemonic TIME when considering how

to best manage the wound and provide an optimal wound bed for

healing. The TIME mnemonic is described as follows:28

• T - Tissue:

This step describes whether the tissue is healing or is not

viable and needs debridement. When assessing a wound, a

look at the wound bed will tell the provider of the presence of

Page 28: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

28

eschar or slough that needs to be removed. Performing

debridement then provides a healthier wound bed in which

new tissue can grow.

• I - Infection or Inflammation:

Infection and inflammation may be apparent when assessing

certain types of wounds, as some signs, such as odor, can

indicate a pathologic process going on. However, signs of

infection or inflammation in a wound may also be subtle and

difficult to accurately determine without a wound culture and

examination by a trained eye. Following wound culture, the

patient may need antibiotics in the form of topical or systemic

treatments to control bacterial growth. If inflammation is

present, anti-inflammatory medications can control continued

irritation and swelling.

• M - Moisture:

Wound moisture requires a careful balance to avoid both an

overly dry wound bed, which can delay healing, as well as an

overly moist wound bed, which can lead to maceration of

surrounding tissues. To balance appropriate moisture levels,

the nurse must use the appropriate types of dressings that

will retain a moist wound base from which to work without

causing excess moisture on the edges of the wound or the

surrounding tissues.

• E - Edge of the wound:

Normal wound healing results in the wound edges migrating

together to form a solid framework that indicates the wound

Page 29: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

29

has healed. When the edges are not coming together, there

may be excess necrotic tissue still in the wound that needs to

be debrided, or there may be other systemic factors that

should be considered that are causing delayed wound healing,

such as with the presence of certain types of chronic disease.

Wound edges that are rolled or rounded may not migrate

properly and can cause delayed healing. There may be

evidence of other damage or disease processes associated

with the wound, such as skin maceration or undermining of

the wound edges. Ultimately, after management measures

are taken, the wound edges should begin to migrate and fill in

the wound tissue in a healthy and responsive manner.

The base of the wound, or the wound bed, should remain moist to

promote new tissue growth. Alternatively, the skin surrounding the

wound should be dry to prevent maceration and further skin

breakdown. It is therefore important to concentrate on keeping the

wound bed at the base of the wound moist while cleaning and drying

other areas.

Wound Protection And Dressing Types

Wound dressings are applied to the wound to keep the wound bed

moist. This moist, warm environment can be maintained for wound

healing by the application of the right type of dressing that retains

moisture, is semi-occlusive to allow for wound drainage, and that will

not stick to the wound bed.29

Foam dressings are thickened dressings that contain foam as a type of

padding to protect the wound. Used in a number of different wound

Page 30: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

30

types, foam dressings can be packed into very deep wounds to fill

space or they may be placed on top of superficial wounds to provide

padding and protection from further injury. Foam dressings often have

adhesive borders around the outside edge of the foam sheet. The

adhesive allows the dressing to stick to the skin surrounding the

wound and hold it in place. They may be changed several times a

week, depending on the condition of the wound and the clinician

should take care to examine the surrounding skin to ensure it is not

being damaged by regular addition and removal of the adhesive from

the dressing.21,30

Impregnated dressings are those that are typically made up of gauze

and are infused with a type of chemical, such as petroleum, silver, or

collagen. Impregnated dressings are designed to keep the wound bed

moist while promoting wound healing. They are available as either flat

sheets of dressing that come in various sizes or they may be available

in small strips that can be packed into wounds, such as in cases where

wound tunneling is present.21 Impregnated dressings are often applied

once per day. The gauze dressing is placed in the wound bed. It is

typically flexible enough that it can be pressed lightly into the wound

bed without needing to cut down the size of the gauze sheet. A larger

dressing is then placed over the wound site for protection and to help

keep the impregnated dressing place. Examples of impregnated

dressings available include Vaseline gauze and Xeroform.21,30

Transparent dressings are not typically used for wound healing, but

they are included here as a type of wound dressing in that they can be

placed over the wound and provide a barrier to prevent pathogens

from entering the wound bed. Because they are transparent, these

Page 31: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

31

types of dressings allow the clinician to visualize the wound bed and to

identify changes that can signify infection or complications.

Transparent dressings are semi-occlusive in that they allow some

oxygen to reach the wound, which decreases the risk of anaerobic

microbes from growing in the wound bed to cause an infection. They

do not absorb excess fluid from the wound and they are not intended

for deep wounds. However, transparent dressings can be placed over

shallow wounds and superficial skin tears, as long as neither type of

wound is infected.30 Examples of transparent dressings include

Tegaderm, Op-Site, Blisterfilm, and AcuDerm.

Hydrogel dressings are designed to maintain a moist wound

environment because they contain a certain amount of gel within the

dressing that maintains moisture but they can also absorb some

exudate and drainage from the wound. Hydrogel dressings also work

as a form of autolytic debridement in that they are placed in the

wound bed, and they further keep the environment moist and thereby

soften and break down necrotic tissue that can be removed when the

dressing is changed.

Hydrogel dressings are made of polymers that can maintain wound

moisture, but they may also have added components that can provide

moisture control, such as silicone, polyethylene oxide, or glycerin.21

These types of dressings are placed on the wound bed; if the size

available is larger than the size of the wound, it may be cut with sterile

scissors down to fit the size and shape of the wound bed. Adhesive

backing is often present on the dressing, which is removed after the

dressing is placed on the wound to provide a non-occlusive surface

that permits some airflow and fluid distribution. Once placed on the

Page 32: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

32

wound bed, the dressing is then covered with a larger dressing, such

as a gauze pad, to provide protection. The hydrogel is typically

changed every day. Examples of hydrogel dressings available on the

market include DuoDERM, Vigilon, and Saf-Gel, although there are

many more brands available for use.21,30

Wound Exudate and Dressing Selection

Exudate is a type of drainage that comes from the wound. It is

necessary for a wound to create exudate, as this process can help to

keep the wound bed moist. Exudate contains many important

properties that are essential to the health of the wound, including

electrolytes, protein, growth factors, and inflammatory mediators. It is

usually clear or pale yellow in color and has a watery composition.

Exudate plays a critical role in keeping the wound bed moist to

facilitate migration of skin cells across the wound during healing.33

Exudate may vary in its appearance, depending on how the wound is

healing and if infection is present. The clinician should note whether

exudate is present as well as its color and consistency. For example,

exudate may drain from a wound and be described as a moderate

amount of serous drainage. When an infection is present, exudate may

have an odor and may be thick and purulent. Wound dressings are

applied to absorb exudate and to promote wound healing. Some

examples of dressings that may be applied to absorb exudate include

dry dressings and pads, hydrocolloid dressings, alginates, and

hydrofiber dressings.

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

33

Dry Dressing

Dry dressings consist of gauze in the form of a gauze pad or bandage

that is applied to the wound as a covering. Dry gauze may be placed

on the wound bed and then covered with tape or wrapped with a

bandage. The gauze is designed to absorb small amounts of exudate

and then it can be removed; however, when large amounts of exudate

are present, the gauze may either become saturated and if not

changed quickly enough can lead to a wet layer of drainage covering

the wound, or it may stick to the wound bed and cause damage when

the nurse tries to remove it.30

Gauze dressings are often used for surgical wounds, but they may be

applied to many different types of wounds from various causes; the

use of gauze to cover a wound is based on the patient’s condition, how

the wound is healing, and whether there are other factors to consider

that can affect wound healing. Gauze is useful because it not only

absorbs small amounts of exudate but it also protects the wound from

infection by providing a barrier that prevents bacteria from entering

the wound, particularly when the gauze dressing is sterile.

Gauze pads are available in various sizes and may come in containers

in which they are packed together for multiple use or they may be

wrapped individually. Gauze is also available as a wrap, which is

flexible and comes in a large roll that can be wrapped around an

extremity or other area covering a wound to hold the underlying

dressing in place. Examples of dry gauze dressings that may be used

for wounds include a number of different products manufactured by

various companies under different brand names and that come in

various sizes and thicknesses for a multitude of purposes. Telfa is

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

34

another type of gauze dressing contains a coating so that it will not

stick to a wound.

Wet-to-dry Dressing

Wet-to-dry dressings are also a form of dressing that is used for

absorbing exudate from wounds. These types of dressings are used for

mechanical debridement when they are saturated with saline, placed

on the wound bed, and then allowed to dry, absorbing excess exudate

and dead skin tissue along with it. The dried exudate is removed when

the dressing is removed. As stated, wet-to-dry dressings, while still

commonly ordered among many facilities as a form of mechanical

debridement, are being replaced with other forms of treatment that

are less damaging to the skin tissue and that are less painful for the

patient.

Hydrocolloid Dressing

Hydrocolloid dressings are another form of dressing material that is

designed to absorb exudate from the wound bed when the dressing is

placed on the wound. Hydrocolloid dressings typically contain polymers

and other elements such as pectin or carboxymethylcellulose, and they

are waterproof. The hydrocolloid dressing is applied to the wound — it

may need to be cut to fit the size of the wound — and it absorbs

exudate from the wound bed without drying the tissue too much.

Some types of dressings have a mark that indicates when the dressing

has become saturated. When the dressing has absorbed enough

exudate, it should be changed. Hydrocolloid dressings are changed

anywhere from every 2 to 7 days, depending on the amount of

exudate and how fast the dressing absorbs fluid.21,30 The dressing

should not be left in place if it becomes saturated.

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

35

Alginate Dressing

Alginate dressings are designed for wounds that absorb large amounts

of exudate; these types of dressings can be placed in the wound bed

to rapidly absorb excess fluid while preventing the wound from drying

out. An alginate dressing is made up of either brown seaweed or a

combination of elements such as calcium or sodium salts. The dressing

is not pre-moistened, but instead, it becomes a gel when it is exposed

to moisture in the wound. For this reason, alginate dressings are best

used for wounds that produce significant exudate, rather than those

that are mostly dry or only slightly moist.

Its important for the clinician to be aware that if there is not enough

moisture in the wound bed, the alginate dressing may not keep its gel-

like features and it may end up drying out the wound. Alginate

dressings are available in many sizes of sheets, as well as ropes or

pads. This type of dressing is applied to the wound bed and then

covered with another dressing to keep it in place. In addition to

wounds that excrete large amounts of exudate, alginate dressings are

most useful for wounds that consistently ooze, such as those that have

just had surgical or sharp debridement because they contribute to

hemostasis and can staunch blood flow when oozing is present.21,30

Hydrofiber Dressing

Hydrofiber dressings work in a manner similar to alginate dressings in

that they expand upon contact with excess moisture. This action

makes hydrofiber dressings useful for wounds that create large

amounts of exudate. Unlike alginate dressings, though, hydrofiber

Page 36: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

36

dressings do not contribute to hemostasis, so they are not necessarily

the best type of dressings to use when wounds are oozing blood.30

Hydrofiber dressings are made up of carboxymethylcellulose, which

acts as an absorptive agent to collect exudate as it comes from the

wound bed. When placed in the wound bed, the hydrofiber dressing

wicks excess moisture away from the wound and collect it within the

dressing, where it becomes a gel when it is exposed to the moisture.

In some cases, hydrofiber dressings should be moistened with saline

before application; they come in sheets that can be cut to the

appropriate size, which should be slightly larger than the wound bed.

Some hydrofiber dressings are also impregnated with antibiotics, such

as silver, so they work to prevent or treat infection while also

controlling moisture levels in the wound.21,30

Additional Considerations for the Management of Exudate

After the clinician has applied a dressing to the wound, it may be

helpful to then apply a barrier cream or emollient to the surrounding,

intact skin in order to protect it from skin breakdown and to keep it

healthy and dry. Management of exudate is important to keep

surrounding skin healthy and dry but it has also been shown to reduce

instances of infection, reduce the number of dressing changes needed

in a wound, and improve patient quality of life, according to a review

from Wounds International.33

The amount of exudate produced by a wound is related to the size of

the wound. As a wound heals, it typically tends to produce less

exudate; however, a very large wound may produce large amounts of

exudate that require special dressings for control of fluid volume. For

Page 37: Wound Care: Part II - Nurse CEUs Online & Physiology. Abstract ... best; causes of skin breakdown, types of wounds, ... and describe the type of pain present

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

37

example, a patient who has been burned may have one or more large

wounds that cover a significant area of the body. Because of the size

of these wounds, they typically produce much more exudate that

needs to be controlled and maintained when compared to another type

of wound, such as a small pressure ulcer on the heel.33 If a patient has

a wound with a significant amount of exudate, the clinician should

determine the most appropriate type of dressing that will absorb

excess fluid and keep the wound clean and moist.

There are many indicators that demonstrate that exudate is not being

well controlled, such as saturated dressings or changes in the

appearance of the dressing on the outside of the wound, delayed

wound healing, skin breakdown on the areas surrounding the wound,

patient pain and embarrassment over the appearance, odor, or

characteristics of the wound, electrolyte imbalances in the patient from

loss of electrolytes and protein in the exudate, the need for frequent

dressing changes, and soiling of clothing and linens near the wound

dressing.

Control of exudate is important to prevent skin breakdown and further

destruction of wound tissue that cannot only delay healing but can

cause the condition to worsen. While it is important to keep the wound

bed moist, the balance of moisture is imperative to maintain, as too

little moisture, such as by absorbing every ounce of exudate until the

wound bed is completely dry, will delay healing and can cause tissue

damage. Alternatively, too much moisture and lack of exudate control

will keep the wound and surrounding tissue too moist, which can lead

to softening of the skin, maceration, and skin breakdown.

Summary A treatment plan for wound care revolves around the assessment and

preparation of the wound for successful treatment and healing.

Prevention of wound development is primary to safe and appropriate

skin care. Early recognition of wound development allows for prompt

assessment and interventions to prepare the wound through cleaning

and removal of unviable tissue through a type of debridement. There

are various types of debridement that may be initiated depending on

the wound type and the level of professional skill and training required

for the debridement procedure.

Wound protection through initial selection of the type of dressing

requires knowledge of the varied wound products. The management of

exudate is basic to wound healing. Exudate plays a critical role in

keeping the wound bed moist to facilitate migration of skin cells across

the wound during the healing process. The primary goal in the initial

treatment of a wound is to promote healthy tissue within the wound

bed and wound healing through ongoing treatment and therapy.

Ongoing and advanced treatment and therapy options used to promote

wound healing are worthy of further study, and are covered in Wound

Care Part III of this series. Its important to assess all factors that

could affect the process of wound healing, such as wound bed

moisture levels and new tissue growth.

Correct Answers: 1. In the initial assessment, a clinician should consider,

examine, determine and/or document the following?

a. Underlying conditions that could delay wound healing “Information about how the wound developed, how long it has been present, and whether the patient has taken measures to treat the wound are important aspects to note and document in the initial assessment. The clinician should also determine if the patient has any underlying conditions that would contribute to wound development or delayed wound healing, such as diabetes, malnutrition, or immobility.”

2. True or False: Dry necrotic tissue has a yellow or gray

appearance.

b. False “Necrotic tissue is one element that should be removed from the wound during debridement. When moist, necrotic tissue may appear as yellow or gray; and, when dry, necrotic tissue has the appearance of black, tough eschar that may be thick or leathery.”

3. The use of sterile, medical-grade maggots placed in the

wound bed

b. is an example of biological debridement. “Perhaps one of the most interesting and oldest forms of debridement is the use of biological substances on the wound surface to break down and loosen debris in order for it to be quickly removed. One of the most common forms of biological debridement is the use of medical-grade maggots placed in the wound bed. Several sterile maggots — the number of maggots used is determined by the size of the wound — are placed in the wound bed and then covered with a light dressing or gauze.”

nursece4less.comnursece4less.comnursece4less.comnursece4less.com

46

4. The concept of wound bed preparation has been devised as a structured approach

a. to promote healthy tissue within the wound bed. “The concept of wound bed preparation has been devised as a structured approach to promoting healthy tissue within the wound bed while supporting the effectiveness of other forms of therapy and treatment. Preparation of the wound bed allows the clinician to determine if there are factors that are affecting the process of wound healing; this concept is most often used when dealing with a chronic wound that is not healing. Wound bed preparations focuses on maintaining moisture levels in the wound bed, promoting new tissue growth, and preventing infection.”

5. TIME is a mnemonic used to best manage a wound and to

promote healing: It stands for

b. Tissue–Infection or Inflammation–Moisture–Edge of the Wound. “The clinician can implement the mnemonic TIME when considering how to best manage the wound and provide an optimal wound bed for healing. The TIME mnemonic is described as follows: Tissue … Infection or Inflammation … Moisture … Edge of the Wound.”

6. Impregnated dressings are those that are typically made up

of gauze that are infused with

c. a chemical, i.e., petroleum, silver, or collagen. “Impregnated dressings are those that are typically made up of gauze and are infused with a type of chemical, such as petroleum, silver, or collagen.”

47

7. The only exception to removal of eschar is when it is found intact on a

a. dry heel wound “There may be times when it is better for a wound not to be debrided. As stated, the AHRQ has specified that dry heel wounds that are covered with eschar should not be debrided because it may be difficult to determine the depth and extent of the wound.”

8. True or False: The Agency for Healthcare Research and

Quality (AHRQ) stated “dry gangrene” that is also a contraindication to debridement.

a. True “… a condition known as dry gangrene, which develops as a result of poor blood flow rather than an infectious process, is also considered a contraindication to debridement because of the potential for infection and lack of blood flow to the affected site.”

9. Impregnated dressings are often applied

b. once per day. “Impregnated dressings are often applied once per day.”

10. If the practitioner suspects a foreign object in the wound

but cannot visualize it, the practitioner should

c. use an X-Ray or MRI to find any foreign object.

“Identification of a foreign object may require diagnostic tests, such as an X-Ray or MRI…. If the clinician suspects a foreign object in the wound but cannot visualize it, he or she should not blindly probe the wound to search for it to be removed, as this can cause further trauma to the tissue and could lead to increased bleeding or infection.”

48

11. True or False: Alginate dressings require dryness in the wound bed to maintain its gel-like features during wound treatment.

b. False “… alginate dressings are best used for wounds that produce significant exudate, rather than those that are mostly dry or only slightly moist.”

12. When assessing erythema on a person with dark skin, the clinician should note

b. that the skin may appear to have purple undertones. “It may be difficult to assess areas of erythema among patients who have dark skin. In these cases, skin may appear to have purple undertones and the skin surface may be shiny and firm. The clinician can use a direct light over the affected area for assessment and look for other signs of injury beyond erythema, such as tissue swelling and warmth.”

13. True or False: Identification of a foreign object may require

X-Ray or MRI to diagnose cause of a wound.

a. True “Identification of a foreign object may require diagnostic tests, such as an X-Ray or MRI.”

14. Pulsatile lavage with suction can be used on

a. many different types of wounds. “Further, pulsatile lavage with suction can be used on many different types of wounds and it is site specific, meaning a patient does not have to have an extremity or the entire body submerged in a tub of water to derive the benefits of debridement. Pulsatile lavage has been used for successful debridement of diabetic wounds, venous ulcers, surgical wounds, pressure ulcers, and wounds that have become infected. It can also be used on complicated wounds where tunneling or undermining is present.”

49

15. Collagenase, Panafil, and papain and urea (Accuzyme) are examples of

b. enzymatic debridement preparations. “Examples of enzymatic debridement preparations include collagenase, Panafil, and papain and urea (Accuzyme).”

16. Irrigation by hand with a syringe is a type of debridement most effective for

c. non-infected/minor wounds. “Irrigation by hand with a syringe … is most effective for wounds that are not infected or that only have minor infections, those that do not contain significant amounts of debris, and those that do not have thick eschar, as the pressures used with irrigation are not high enough to loosen and remove very thick or tough eschar.”

17. Autolytic debridement is

b. a painless form of removing dead tissue. “Autolytic debridement is one of the most painless forms of removing dead tissue; however, because it can take longer when compared to some other forms of debridement, the patient may be at a greater risk of infection with this process.”

18. A wound requires a ____________ wound bed in order to

best promote healing.

a. moist “A wound requires a moist wound bed in order to best promote healing.”

19. ________________ dressings are another form of dressing material that is designed to absorb exudate from the wound bed when the dressing is placed on the wound.

a. Hydrocolloid “Hydrocolloid dressings are another form of dressing material that is designed to absorb exudate from the wound bed when the dressing is placed on the wound.”

20. A study showed that pulsatile lavage with suction had an

over _____ percent increase in granulation tissue formation per week when compared to 4.8 percent increase among those who used whirlpool therapy.

b. 12

“… wound care patients who received pulsatile lavage with suction had an over 12 percent increase in granulation tissue formation per week when compared to 4.8 percent increase among those who used whirlpool therapy.”

21. __________ is an essential component of epithelialization and __________ wounds heal at a faster rate.

b. Moisture; open “… moisture was an essential component of epithelialization and that open wounds healed at a faster rate when kept moist.”

22. Unlike alginate dressings, hydrofiber dressings

b. expand upon contact with excess moisture. “Hydrofiber dressings work in a manner similar to alginate dressings in that they expand upon contact with excess moisture. This action makes hydrofiber dressings useful for wounds that create large amounts of exudate. Unlike alginate dressings, though, hydrofiber dressings do not contribute to hemostasis, so they are not necessarily the best type of dressings to use when wounds are oozing blood.”

51

23. Irrigation of a wound must be done at a pressure between ___________________ in order to be effective.

c. 4 psi and 15 psi “Irrigation may be performed at the bedside by the nurse; it must be done at a pressure between 4 psi and 15 psi in order to be effective: pressures less than 4 psi are not strong enough to loosen tissue and pressures greater than 15 psi have been shown to damage healing skin and to drive debris deeper into the tissues.”

24. One of the most common forms of testing for sensation is

by using the

b. monofilament test. “One of the most common forms of testing for sensation is by using the Semmes-Weinstein monofilament test.”

25. If a patient does not have sensation during properly performed testing, this may indicate

d. neuropathy. “A patient who cannot consistently detect the monofilament during the test should receive further evaluation for decreased sensation due to neuropathy.”

26. A common form of biological debridement is the use of

c. medical-grade maggots. “One of the most common forms of biological debridement is the use of medical-grade maggots placed in the wound bed.”

52

27. When signs of wound infection occur, the patient may benefit from

a. a short-term antimicrobial wound cleansing product. “If odor or other signs of infection are present in the wound, the patient may benefit from a short-term cleansing regimen of antimicrobial wound cleansing products, despite their potential cytotoxicity.”

28. Foam dressings are

a. thickened dressings with foam padding for wound protection. “Foam dressings are thickened dressings that contain foam as a type of padding to protect the wound. Used in a number of different wound types, foam dressings can be packed into very deep wounds to fill space or they may be placed on top of superficial wounds to provide padding and protection from further injury.”

29. True or False: Preparation of the wound bed focuses on

maintaining moisture levels in the wound bed, promoting new tissue growth, and preventing infection.

a. True “Wound bed preparations focuses on maintaining moisture levels in the wound bed, promoting new tissue growth, and preventing infection.”
