Cytotoxic drugs (CDs) are life-saving for patients with cancer but they can
be very dangerous for the staff members who must handle and administer them.
In order to maintain the highest safety standards for patients, clients and
staff members, these procedures are instituted.
Storage:
CDs must be stored inside of closed containers to prevent accidental breakage.
CD storage containers must be labeled appropriately.
Spills:
A chemotherapy spill kit shall be assembled and maintained near the site
where CDs are mixed or administered. ________________________ (fill in the name
of the person responsible) shall ensure the spill kit is prepared and replenished
when necessary.
If the spill is outside of the Biological Safety Cabinet (BSC), remove non-essential
personnel from the area. Spills shall be cleaned up by absorbing the spilled
liquid with absorbent pads while wearing gloves, gown and mask. The contaminated
materials shall be placed in the yellow "Chemo" bag located in the preparation
or administration area. The contaminated area shall be cleaned with water and
detergent (NOT disinfectant). For any large spill (greater than 5 ml of CD),
_________________ and the Safety Director shall be notified and an accident
report filed.
Personnel Contamination
If during preparation or administration of a CD, your protective clothing or
body is contaminated with the drug, immediately stop the procedure and remove
the contaminated gloves or clothing. Wash the affected area with detergent (NOT
disinfecting) soap and water. If your eyes are contaminated, immediately call
out for assistance from other workers; flush your eyes at the eye wash station
for at least 15 minutes. Notify __________________________________ and the Safety
Director of the incident and seek medical attention if warranted.
Preparation: All CDs shall be drawn up, reconstituted or prepared inside
of the Biological Safety Cabinet (BSC) located in the treatment area. Only staff
members who have been trained and authorized by______________________________
shall attempt to mix, prepare or administer CDs. All drugs shall be handled
in accordance with the manufacturer's instructions and the following procedures:
a. Assemble all reagents on an absorbent liner within the BSC.
b. Turn on the hood at the switch and remove non-essential people from the area.
c. Wash your hands with normal detergent soap but not disinfectant soap.
d. Put on an impervious, lint-free gown with elastic cuffs. This "cover" should
only be worn in the CD prep/administration area.
e. Put on a pair of unpowdered chemo gloves with the glove over the cuff of
the gown or smock. For extended procedures, double gloving is suggested. Gloves
should be changed every 30 minutes.
f. Attach injection pins to drug bottles.
g. Select a leur-lock syringe based on estimated volumes (syringe should never
be more than half to two-thirds full of solution.)
h. Attach the syringe to an appropriate needle.
i. Draw up the required amount of diluent.
j. Stick the needle into the drug container and draw out a small amount of air.
Inject a small amount of diluent. Repeat this process until the entire amount
if diluent is injected into the drug vial. The goal of this step is to never
have the drug in a "pressurized" container to decrease the likelihood of spraying
or aerosolization.
k. With the needle still in the vial, mix the solution by gently swirling until
all particulates are dissolved.
l. Invert the vial and withdraw the solution in small amounts. Inject an equal
amount of air back into the vial. Repeat this process until all the drug is
drawn up into the syringe.
m. Aspirate slightly on the plunger to remove all drug from the needle and hub
then remove the needle from the syringe.
n. Wipe the syringe with an alcohol gauze and replace the cap on the needle
using the one-handed technique.
o. Label a zip-lock bag and the syringe with the patient's name, the date and
the appropriate sticker.
p. Place the syringe in a zip-lock bag for transport to the patient administration
area.
q. Place all disposable supplies from the hood in the yellow receptacle marked
"Chemo" located next to the BSC. Do not recap remaining needles - dispose of
them directly in the sharps container inside of the BSC. When the sharps container
is full, seal it and place it inside of a yellow "Chemo" bag and place it in
the normal collection box for sharps containers.
r. Remove your gown and gloves without touching the outside and dispose of them
in the yellow "Chemo" bag next to the BSC.
s. Wash your hands with normal detergent soap but not disinfectant soap.
When CDs are being prepared or administered, the area shall be clearly identified
with the appropriate sign and non-essential personnel kept at least 5 feet away.
Eating, drinking, smoking and chewing gum, applying cosmetics and food storage
are prohibited in the CD preparation and administration area. These activities
are also prohibited in any areas where patients treated with CDs are hospitalized
or when handling these patients.
Administration:
Only properly trained staff members authorized by ____________________________
shall administer CDs or assist in the procedure. Administration of CDs shall
only be performed in the designated area and non-essential personnel must be
kept at least 5 feet away from the procedure area. All staff members must wear
protective gowns, powder-free latex gloves and eye protection for the duration
of the procedure. The drug manufacturer's directions shall be followed for administration.
The administration area (5 feet surrounding the table) shall be cleaned with
water and detergent (not disinfectant) soap when the procedure is completed.
Patient Care:
Patients who have received CD treatments must be identified with a cage card.
Only authorized and trained staff members shall care for CD patients.
Excretions from CD patients may be hazardous. The chart on the following page
should be used as a guide for determining the risk of exposure. Potentially
hazardous materials must be collected using appropriate protective equipment
and disposed of properly: liquid waste in the sanitary sewer and solid waste
in a yellow "Chemo" bag.
