NURSING CARE OF PATIENTS RECEIVING CHEMOTHERAPY

Chemotherapy

-is the use of chemicals to treat disease.

-Paul Erlich, considered to be the father of chemotherapy,

. The drugs used in cancer treatment vary in their chemical structure , biological side effects and toxicities.

Some are effective in treating one specific types of cancer while others are utilized in the treatment of wide variety of malignancies.

The methods of administration also vary according to the chemotherapeutic and new techniques for safer and more effective administration.

Nursing management - requires knowledge about the treatment -, skill in assessment- technical expertise,- ability and desire to support the client physically and emotionally.

-

Nursing care begins with..........- thorough understanding of the patients condition; -goal of therapy , drug dose, route, schedule, administration principles;- and potential side effect- monitoring responses to the therapy,- reassessing - documenting signs and symptoms,- communicating pertinent information to other members of the health care team.

There are five ways 1. Adjuvant therapy- conjunction with another treatment .2. Neoadjuvant chemotherapy-y to shrink the tumor prior to surgical removal

3. Primary therapy- localized cancer which there is an alternative but less than completely effective treatment.

4. Induction chemotherapy- primary treatment which no alternative treatment exists.

5. Combination chemotherapy- two or more chemotherapeutic agents, allowing each medication to enhance

the action of other.

ROLE OF A NURSEPrior to chemotherapy administration1 Review- The chemotherapy drugs prescription which should have -Name of anti-neoplastic agent.-Dosage-Route of administration-Date and time that each agent to be administered.2. Accurately identify the client 3.Medications to be administered in conjunction with the chemotherapy e.g antiemetics, sedatives etc.

4.. Assess the clients condition including - Most recent report of blood counts including hemoglobin ,hematocrit, white blood cells and platelets. -Presence of any complicating condition eg: infection ,bleeding -Physical status -Level of anxiety -Psychological status.

5. Prepare for potential complications.-Review the procedure and have medication available anaphylaxis

6.Assure accurate preparation of the agent -dosage calculation -Expiry date checked - correct reconstitution -Method of administration7.Assess patients understanding of chemotherapeutic agents and administration procedures.

II. Calculation of drug dosage

- based on body surface area.

III. Drug reconstitution/Preparation-according to hospital policy and guidelines by the manufacturer

-Aseptic technique should be followed.

-Personal protective equipment includes disposable surgical gloves, long sleeves gown and elastic or knit cuffs.

-Protective eye goggles

-To minimize exposure

-Wash hands before and after drug handling.

-Limit access to drug preparation area

IV. Drug administration 1. Route- i)Oral - Emphasize the importance of compliance by the patient with prescribed schedule.

V. - Drugs with emetic potential should be taken with meals.

IV. ii) Intramuscular and subcutaenous –V. -can be administered I/M or subcutaneously

are few in number.VI. VII.-Non-vesicants like L-asperaginase,

bleomycin, cyclophosphamide, methotraxate. Cyta arabine,and some hormonal agents are given I/M & or subcutaneously.

VIII. IX.-Use the smallest gauge needle possible for the

viscosity of the medication.

iii) Intravenous -Common method .-May be given through central venous catheters or peripheral access. -Absorption is more reliable. -This route is required for administration of vesicants and it also reduces the need of repeated injection. -Because the I/V provides direct access to the circulatory system, the potential for infection and life threatening sepsis is a serious complication of I/V chemotherapy.

The following guidelines to be kept in mind:-Inspect the solution, container and tubing for signs of contamination including particles, discoloration, cloudiness, and cracks or tears in bottle or bag-Aseptic technique to be followed-Prepare according to manufacturer’s directions-Select a suitable vein-Large veins on the forearm are the preferred site.-Use distal veins first, and choose a vein above areas of flexion.-For non-vesicant drugs, use the distal veins of the hands (metacarpal veins): then the veins of the forearms(basilic and cephalic veins)

-For vesicants, use only the veins of the forearms. Avoid using the metacarpal and radial areas.

-Avoid the antecubital fossa and the wrist because an extravasation in these areas can destroy nerves and tendons, resulting in loss of function. -Peripheral sites should be changed daily before administration of vesicants-Avoid the use of small lumen veins to prevent damage due to friction and the decreased ability to dilute acidic drugs and solutions. Select the shortest catheter with the smallest gauge appropriate for the type and duration of the infusion (21g to 25g for I/V medications and 19 g for blood products).

-Avoid a vein which has been used for venous access within the past 24 hrs to prevent leakage from a prior puncture site. Prevent trauma and infection at the insertion site. -Apply a small amount of iodine based antiseptic ointment over the insertion site & cover the area with sterile gauze.Intravenous Chemotherapy Via Central Vein Infusion (Hickman Catheter)

V. Documentation -chemotherapeutic drugs, dose, route ,and time -Premedications, postmedications, prehydration and other infusions and supplies used for chemotherapy regimen.

-Any complaints by the patient of discomfort and symptoms experienced before, during, and after chemotherapeutic infusion.

VI. Disposal of supplies and unused drugsa)Do not clip or recap needles or break syringes.b)Place all supplies used intact in a leak proof ,puncture proof, appropriate labeled container.c)Place all unused drugs in containers in a leak proof, puncture proof, appropriately labeled container.d)Dispose of containers filled with chemotherapeutic supplies and unused drugs in accordance with regulations of hazardous

wastes.

VII. Management of chemotherapeutic spills

Chemotherapy spills should be cleaned up immediately by properly protected personnel trained in the appropriate procedure. A spill should be identified with a warning sign so that other person will not be contaminated.

Supplies Required Chemotherapy spill kit containsRespirator mask for air borne powder spillsPlastic safety glasses or gogglesHeavy duty rubber glovesAbsorbent pads to contain liquid spillsAbsorbent towels for clean up after spillsSmall scoop to collect glass fragmentsTwo large waste disposal bags

Protective disposable gownContainers of detergent solution and clear tap water for post spill clean up.Puncture proof and leak proof container approved for chemotherapy waste disposalApproved, specially labeled, impervious laundry bag.

Spill on hard surfaceRestrict area of spillObtain drug spill kitPut on protective gown, gloves, gogglesOpen waste disposal bagsPlace absorbent pads gently on the spill; be careful not to

touch spill.

Place absorbent pad in waste bagCleanse surface with absorbent towels using detergent solution and wipe clean with clean tap water.Place all contaminated materials in the bag.Wash hands thoroughly with soap and water.

Spill on personnel or patientRestrict area of spillObtain drug spill kitImmediately remove contaminated protective garments or linenWash affected skin area with soap and waterIf eye exposure-immediately flood the affected eye with water for at least 5 mts; obtain medical attention promptlyNotify the physician if drug spills on patient.Documentation- Document the spill.

VIII. Staff EducationAll personnel involved in the care should receive an orientation to chemo. Drugs including their known risk , relevant techniques and procedures for handling, the proper use of protective equipment and materials, spill procedures, and medical policies covering personnel handling chemo. agents.Personnel handling blood, vomitus, or excreta from patients who have received chemotherapy should wear disposable gloves and gowns to be appropriately discarded after use.

IX. Extravasation management-Etravasation is the accidental infiltration of vesicant or irritant chemotherapeutic drugs from the vein into the surrounding tissues at the I/V site. -A vesicant is an agent that can produce a blister and /or tissue destruction. -An irritant is an agent that is capable of producing venous pain at the site of and along the vein with or without an inflammatory reaction. -Injuries that may occur as a result of extravasation include sloughing of tissue , infection, pain ,and loss of mobility of an extremity.

1.Prevention of extravasation-Nursing responsibilities for the prevention of extravasation include the following -Knowledge of drug s with vesicant potentialSkill in drug administration-Identification of risk factors e.g. multiple vene punctures-Anticipation of extravasation and knowledge of management protocol-New venepuncture site daily if peripheral access is used

-Central venous access for 24 hrs vesicants infusion-Administration of drug in a quiet, unhurried environment-Testing vein patency without using chemotherapeutic agents-Providing adequate drug dilution-Careful observation of access site and extremity throughout the procedure-Ensuring blood return from I/V site before, during, and after vesicant drug infusion.-Educating patients regarding symptoms of drug infiltration , e.g. pain, burning, stinging sensation at I/V site.

2.Extravasation management at peripheral site-According to hospital policy and approved antidote should be readily available.-The following procedure should be initiated-Stop the drug-Leave the needle or catheter in place-Aspirate any residual drug and blood in the I/V tubing, needle or catheter, and suspected infiltration site-Instill the I/V antidote-Remove the needle

If unable to aspirate the residual drug from the IV tubing , remove needle or catheterInject the antidote sub-cutaneously clockwise into the infiltrated site using 25 gauge needle; change the needle with each new injectionAvoid applying pressure to the suspected infiltration siteApply topical ointment if orderedCover lightly with an occlusive sterile dressingApply cold or warm compresses as indicatedElevate the extremityObserve regularly for pain, erythema, induration, and necrosisDocumentation of extravasation management. All nursing personnel should be alert and prepared for the possible complication of anaphylaxis.
