Perioperative Nursing- it is the nursing care rendered to the total surgical experience of the patient. 3 Phases y Preoperative phasey y
Intraoperative phase Postoperative phase
Effects of Surgery on a ClientA. Physical Effects B. Psychological Effects
The Surgical Risk PatientsA. Extremes of age B. Malnourished (emaciation/obesity) C. Dehydrated patients D. Patients with severe trauma or injury, infection or
sepsis E. Patients with cardiovascular disease F. Endocrine dysfunction G. Hepatic/Renal disease
Medications That Can Affect the Surgical Client Antibiotics Antidysrhythmics Anticoagulants Corticosteroids Insulin Diuretics Antidepressant
Classifications of Surgeryy According to Urgency:
Emergent requires immediate attention; Disorders maybe life-threatening. 2. Urgent- surgical problem requires prompt attention within 24-30hrs 3. Required- condition requires surgery within a few weeks 4. Elective- approximate time for surgery is at the convenience of the patient, failure to have surgery is not catastrophic 5. Optional- is scheduled completely at the preference of the patient.1.
Classification of Surgeryy According to Degree of Risk:
Major- high degree of risk > maybe complicated/prolonged > large losses of blood may occur > vital organs maybe involved > post-op complications may be likely Minor- little risk with few complications > often performed in a day
Classifications Of Surgeryy According to Purpose 1. 2. 3. 4. 5.
Diagnostic- verifies suspected diagnosis Exploratory- estimates the extent of the disease or injury Curative- removes/repairs damage tissues Ablative- Removing diseased organ that cant wait anymore Reconstructive-partial or complete restoration; bringing back orig. appearance and function
y Cont. y Constructive- repairing damaged tissue/congenitally defective organ y Palliative relieves symptoms but does not cure the underlying diseases
Preoperative Phase
Informed Consent (Operative Permit)
Obtaining Inform Consent1. The surgeon is responsible for obtaining the consent for 2. 3. 4. 5. 6.
surgery. No sedation should be administered to the client before he/she signs the consent. Minors may need a parent or legal guardian to sign the consent form. Older client may need a legal guardian to sign the consent form. The nurse may witness the client s signing of the consent form. If the patient is unable to write, an X to indicate his sign is acceptable if there is a signed witness to his mark.
Pocedures Requiring Permit1. Surgical procedures where scalpel,scissors, suture,
hemostats or electrocoagulation maybe used. 2. Entrance into a body cavity 3. Radiologic procedure, particularly if contrast material is required. 4. General anesthesia, local infiltration and regional block

y A group of procedures that prevent
contamination of microorganisms through the knowledge of contain and control. Sterile Technique Methods by which contamination of an item is prevented by maintaining the sterility of an item/area involved with the procedure.
Basic Principles of Aseptic Technique1. All items used within the sterile field must
be sterile. 2. A sterile barrier that has been permeated must be considered contaminated. 3. The edges of a sterile wrapper or container are considered unsterile once the package is opened. 4. Gowns are considered sterile from chest to the level of the sterile field, and the sleeves to 2inches above the elbows.
Tables are sterile at table level only. Sterile persons and items touch only sterile areas; unsterile persons and items touch only unsterile areas. Movement around the sterile field must not contaminate the field. All items and areas of doubtful sterility are considered contaminated.
Recommended Practice IIIy Items used within the sterile field should be sterile y Event-related sterility system
- sterility is not altered overtime, but may be compromised by certain events/environmental conditionsy Shelf life
- refers to the time an item may remain on the shelf and still maintain its sterility. y Spaulding Criteria - are used to determine the potential for transmission of infectious agents.
Recommended Practice IVy All items introduced to a sterile field should be opened, dispensed and transferred by methods that maintain item sterility and integrity. 1. The surgical team should practice careful aseptic technique during all invasive surgical procedures. 2. Unscrubbed individuals should open wrapped sterile supplies by opening the wrapper flap farthest away from them first. 3. Sharps and heavy objects should be presented to the scrubbed person/opened on a sterile surface. 4. Peel pouches should be presented to the scrubbed person. 5. Rigid container systems should be opened on a separate surface.
y When dispensing solutions, the solution receptacle on the sterile field should be placed near the table s edge, or held by scrubbed person.
Strike- through - contamination of sterile surface by moisture that has originated from a non-sterile surface and penetrated the protective covering of the sterile item
y Medications should be delivered to the sterile field in an aseptic manner.
Recommended practice V y A sterile field should be maintained and monitored constantly. 1. A sterile field should be prepared in the location in which it will be used. 2. For unsterile personnel, movement around the sterile field should maintain a distance of at least 12 inches from the sterile field. 3. Sterile fields should be prepared as close as possible to the time of use. 4. Sterile field should not be covered. 5. Conversations in the presence of a sterile field should be kept to a minimum.
Recommended Practice VIy All personnel moving within or around a sterile field should do y
y
y y
so in a manner that maintains the sterile field. Unscrubbed personnel - should face sterile fields on approach - should not walk between two sterile fields Scrubbed personnel - should keep their arms and hands above the level of the waist at all times. - arms should not be folded with the hands in the armpits - should avoid changing levels. The number and movements of the surgical team should be kept to a minimum. When a break in the sterile technique occurs, corrective action should be taken immediately.
Recommended Practices for traffic Patterns in the Perioperative Practice Settingy Non- Restricted Area y Semi-Restricted Area y Restricted Area y Transition Zone
Recommended Practices for Surgical AttireSurgical Attirey Helps contain bacterial shedding and promotes environmental y y y y
control. If a two-piece pantsuit is worn, the top of the scrubsuit should be secured at the waist or fit close to the body. Should be changed daily or whenever it becomes visibly soiled, contaminated or wet. Lab coats/cover gowns should be removed before entering a semi- restricted/restricted area Non-scrubbed personnel should wear long-sleeved jackets that are buttoned/snapped closed during use.
Head Covery Headgear should be donned before the scrub attire to
prevent fall-out from the hair collecting on the scrub attire. y Personnel should cover head and facial hair, including sideburns and necklines, when in the semi-restricted and restricted areas of the surgical suit. y Contaminated headgear must be removed and laundered by the facility.
Surgical Masky Should fully cover both mouth and nose and be
secured in a manner that prevents venting. y Double mask is unacceptable, doesn t increase filtration. y Should be removed by handling only the ties, should be discarded immediately. y Should not be saved by hanging them around the neck or tucking them into a pocket for future use
Glovesy Sterile gloves must be worn when performing sterile
procedure. y Medical, non sterile gloves are recommended for nonsterile activities. y Should be changed between patient contacts/contaminated items. y Hand hygiene should be performed after gloves are removed.
Recommended Practices for Standard and Transmission based Precautions in the Perioperative Practice settingy Standard Precautions to prevent pathogen transmission should be used during all invasive procedures. y Standard Precautions should include use of protective barriers and frequent hand washing to reduce risk of exposure to potentially infectious materials. y Personnel should take precautions to prevent injuries caused by scalpels and other sharp instruments. y Personnel should handle specimens as potentially infectious material. y Work practices should be designed to minimize risk of occupational exposure to bloodborne and other potentially infectious pathogens.
y Transmission based precautions should be used in addition to standard precautions for patients who are known or suspected to be infected with highly transmissible pathogens. 1. Airborne precautions - examples: rubeola, varicella, tuberculosis - respiratory protection to be worn by susceptible persons - placing surgical mask on patients during transport - elective surgical procedures on TB patients should be delayed until patient is no longer infectious. 2. Droplet precautions - examples: diptheria,pertussis,influenza,mumps - wearing a mask when within three feet of patients - positioning patients at a distance of at least three feet from other patients
3. Contact Precautions
- wearing gloves when caring for patients/coming in contact with items that may contain high concentrations of microbes. - wearing gowns when it is anticipated that clothing will have substantial contact with patients/items in aegs. environment - precautions are maintained during transport. - adequately cleaning and disinfecting patient care equipment and items before use w/ each patient.
Surgical Hand ScrubGoals: y Mechanical removal of soil and transient microbes from the hands and forearms y Chemical reduction of the resident microbial count to as low a level as possible y Reduction of potential of rapid rebound growth of microbes. y Antimicrobial Agents y Iodophors Chlorhexidine gluconate
Anatomic Hand Scrub Technique
Sequence in Removing Soiled Gowns and Gloves at the End of the Procedure
Preparation of Surgical Suppliesy Decontamination contaminates are removed
either by hand cleaning or mechanical methods using specific solutions.y Disinfection-to used to destroy/kill/inhibit
growth of microbes thru application of antiseptic solution.y Sterilization- rendering an item totally free of all
living microorganisms including spores.

Anesthesia and Related ComplicationsCommon Anesthetic Technique Minimal Sedation y Patient remains conscious y Protective reflexes remain intact y Can respond to verbal commands Moderate Sedation -state of depressed level of consciousness that does not impair patient s ability to maintain a patent airway and to respond to physical stimulation and verbal commands. Deep Sedation - Drug induced state during which the patient cant be easily aroused but can respond purposefully after repeated stimulation
General Anesthesiay Complete loss of consciousness y A reversible state that provides analgesia, muscle
relaxation and sedation y It depresses the cerebral cortex where conscious interpretation of pain takes place y Protective reflexes are lost y Produced by IV/inhaled anesthetics
Nitrous Oxidey Colorless, odorless non-explosive gas y Is rarely used alone y When combined with other agents and oxygen----it
y y y y
already serves as potentiator for other inhalation agents High concentration nitrous oxide can produce hypoxia induction agent given with oxygen used alone for short procedures used as inhalation analgesic
Inhalation Anesthesiay Volatile agents 1. Halothane - safe to use - producing rapid smooth induction - non-flammable/non-explosive - very potent - seldom causes nausea and vomiting - non-irritating to mucous membranes -excellent bronchodilator - hepatotoxic -decreases bp - causes malignant hyperthermia
Forane (Isoflourane)y Provides rapid induction, rapid emergence y Low incidence of nausea and vomiting y Does not stimulate excessive secretions y Non-hepatotoxic/non-nephrotoxic y Excellent choice for neurosurgery y Not recommended for children under 2 years of age----
--due to longer airway irritation
Enfluraney Has similar effects to halothane y Muscle relaxation is stronger y Hepatotoxicity is not a problem y Induces electroencephalographic changes causing
seizure.

Sitting Position Lateral Position
Epidural Anesthesiay Injecting local anesthetic into epidural space by way
of a lumbar puncture y Associated with obstetric surgery; anorectal and perineal procedure y Administered via bolus Peripheral Nerve Blocks y Anesthetic is injected around a nerve that supplies sensation to a small area of the body
Intravenous Blocky Involves IV injection of a local agent and the use of an
occlusion tourniquet y Procedures involving the arm, wrist and hand Local Anesthesia (Infiltration) y Used for minors and superficial procedures y The agent is injected in the surgical site Topical Anesthesia y Anesthetic agent is directly applied to the skin and mucous membranes

Suturesy Absorbable sutures
Examples: Chromic, Plain,Polydiaxone (PDS), Polyglactin 910 (Vicryl),Polyglycolic Acid(Biovek) - Used for those who cant return for suture removal/in internal body tissues y Non-Absorbable sutures Examples: Silk,Nylon,Prolene (Polypropylene) - Used either on skin wound closure/in stressful internal environments where absorbable sutures will not suffice - Less scarring because they provoke less immune response
Suturesy Is a medical device used to hold tissue together after
an injury or surgery till healing takes place. Absorbable Sutures material is digested by body cells and fluids during the healing period. Plain dissolves within 5-10 days, Yellow Chromic- dissolves within 1 month, Brown Vicryl/Safil- dissolves within 60-90 days, Lavender PDS (Polydioxone)- dissolves 2 times longer than the other absorbable sutures, White
Non absorbable Suturesy Material is not absorbed or digested by tissues during
healing period Types:
Silk- is an animal product from silk worm cocoons. (Black) Cotton- made from long staple cotton, treated to make it smooth, (White) Prolene- biosynthetic, non-absorbable suture material, as substitute to silk Wire- gives the greatest strength to any suture material

Postoperative Phase3 Stages Immediate Stage - (1-4hrs) after surgery Intermediate Stage - (4 -24hrs) after surgery Extended Stage - (1-4days) after surgery/last follow-up visit with the attending physician
Immediate Postoperative Period Respiratory Position - left lateral with neck extended and upper arm supported on a pillow. - supine with head to side and chin extended forward Check presence of gag reflex Maintain artificial airway until gag reflex returned Oxygen Assess rate and depth of respiration Assess breath sounds Monitor for signs of atelectasis, pneumonia, pulmonary embolism
Cardiovasculary Cardiovascular
Assess skin and check capillary refill Assess peripheral edema Monitor for bleeding Assess pulse rate and rhythm Monitor for hypo/hypertension Monitor for cardiac dysrhythmias Assess for Homan s Sign
Intermediate Post op Periody Monitor Respiratory Status
- coughing/deep breathing q 1-2 hrs - turning in bed q 2hrs - early ambulation - auscultate lungs q 4hrs y Monitor Cardiovascular Status - leg exercises q 2hrs - apply anti-embolic stockings - vital signs, color, temp of skin
Promote Fluid and Electrolyte BalanceMeasure I and Oy Promote Optimum Nutrition
- maintain IV infusion as ordered - Assess return of peristalsis -Progressive increase in diety Promote Return of Urinary Function
- Assess ability to void/ bladder distention - Report to surgeon if client has not voided after8hrs post-op
Transferring the patient from the PACUTransfer Criteria: Patient coming out of General Anesthesia y Vital signs are stable for at least 30mins and are within normal range y Patient is breathing easily y Reflexes has returned to normal y Patient is responsive and oriented to time and place
Patient who had regional anesthesia
y Sensation is restored and circulation is intact y Reflexes has returned y Vital signs have stabilized for at least 30mins y Adequate urine output y Control of pain y Control or absence of vomiting
Post-operative ComplicationsAtelectasis - a collapse of the alveoli with retained mucus secretions - Usually develop 1-2days post-op Aspiration - caused by inhalation of food, gastric contents, water or blood into the tracheobronchial system. - anesthetics and narcotics depress the CNS,causing inhibition of cough and gag reflex
- an inflammatory response in which cellular material
3. Pneumonia
replaces alveolar gas. - may develop 3-5days post-op Assessment: y Dyspnea, increased RR y Crackles over involved lung area y Elevated temp y Productive cough and chest pain y Hypotension y Decreased breath sounds
Pulmonary Embolism-An embolus blocking the pulmonary artery disrupting blood flow to one or more lobes of the lungs y Assessment: y Dyspnea y Sudden sharp chest/upper abdominal pain y Cyanosis y Tachycardia y A drop in blood pressure
Cardiovascular ComplicationsThrombophlebitis y Inflammation of the vein, often accompanied by clot formation y 7-14 days post-opy Assessment: y Vein inflammation y Aching or cramping pain y Vein feels hard and cordlike and is tender to touch y Elevated temperature y Positive Homan s sign
Intervention hydrate patient adequately Avoid massaging to calves or thighs Avoid standing or sitting in one pace or crossing legs Avoid inserting IV s into legs Assess for Homan s Sign
Circulatory ComplicationsHemorrhage -The loss of a large amount of blood externally/internally for a short period of time Shock -Loss of circulatory fluid volume caused by hemorrhage Assessment: y Restlessness y Weak rapid pulse y Hypotension y Tachypnea y Cool clammy skin y Reduced urine output
9. Constipation10. Paralytic Ileus- paralysis of intestinal peristalsis 11. Wound Infection - occurs 3-6 days post op 12. Wound Dehiscence - Separation of wound edges on the suture line - occurs between 5th and 8th day post op 13. Wound Evisceration - Protrusion of the internal organs and tissues through an opening in the wound edges
Urinary Retention-Involuntary accumulation of urine in the bladder as a result of loss of muscle tone - Due to effects of anesthetics/narcotics y Assessment: y Inability to void y Restlessness and diaphoresis y Lower abdominal pain, distended bladder y Elevated BP
Postoperative Discharge TeachingFocus on: y Proper wound dressing y Medications y Diet y Follow-up visit removal of sutures in 7-10 days/ removal of staples in7-14 days y Activity levels-no lifting for 6 weeks y - not to lift anything (>10lbs) y Return to work in 6-8 weeks y Signs and symptoms of complications
Post Chest or Lung Surgery(Pneumonectomy) Discharge Instructiony Breathing exercises y y y y y y
for 3 wks Arm and shoulder exercise -5times a day(10-20 repetitions /exercise Practice standing straight with shoulders even on the affected side No heavy lifting of more than 20lbs for 3-6mos Stop any activity that causes dypnea,chest pain,excessive fatigue Obtain influenza and pneumonia vaccine Report intermittent cough with sputum
Drainsare placed in wounds only when abnormal fluid collections are present/expected Are placed near the incision site: In compartments that are intolerant to fluid accumulation In areas with large blood supply In infected draining wounds Areas that have sustained large superficial tissue dissection Greatest amt is expected during the first 24 hrs are removed when amount of drainage decreases
Types of DrainsGravity1. Penrose Drain 2. T-Tube
Mechanic1. Jackson-Pratt Drain 2. Hemovac
B. Mechanical- these are portable self contained closed wound mechanical devices that suction fluid after collapsing them and closing the valve thus forcing the fluid to be pulled into the collection chamber. examples: Hemovac Jackson- Pratt
Types of Wound HealingFirst Intention Healing - Wounds are made aseptic by minor debridement and irrigation - with a minimum tissue damage and tissue reaction - Wound edges are properly approximated with suture - Granulation tissue is not visible/scar formation minimal
y Secondary Intention Healing- Wounds are left open to heal spontaneously or surgically closed at a later date - Examples include burns, traumatic injuries, ulcers and suppurative infected wounds - Cavity of the wound fills with a red, soft, sensitive tissue (granulation tissue), which bleeds easily, a scar eventually forms. - In infected wounds, drainage may be accomplished by use of special dressings and drains. - Produces deeper wider scar
Care and Handling of Surgical Specimens
Types of Surgical Specimen 1. Routine specimen -specimen that doesn t require immediate attention -placed in a preservation fluid -labeled and sent to Pathology Department ff conclusion of the procedure - scrub nurse should separate like specimens from different locations -specimens not immediately passed off the field should be kept moist in saline -calculi should not be placed in formalin, same with foreign bodies - amputated extremities are wrapped before sending them to the pathology/morgue
2.Diagnostic Specimen
y Frozen Section - Requires special handling and immediate examination
by the pathologist - With verbal report of the findings communicated to the surgeon during the surgical procedure - Examples include breast biopsy/any organ, tumor or lesion - Specimen is sent dry and is properly labeled.
Culturesy Are taken on a patient who comes to the OR with a y y y y y
known/suspected infection 2 types: aerobic and anaerobic, requires different medium for growth This will determine the antibiotic that will specifically affect the microbes Are obtained under sterile condition, using appropriate collection tube. Exact procedure for collecting cultures for specific test will vary from each institution Must be sent to the lab immediately for accurate processing
