Extravasation at the Elbow
Ms. R, 52, is receiving peripheral IV doxorubicin for breast cancer via a 22-gauge catheter in the right antecubital fossa. Twenty minutes in, she reports burning at the site. The nurse sees mild swelling and blanching; there is no blood return. The vesicant kit is on the unit but the nurse has never used it. The infusion has run approximately 40 mL of a 100 mL bag. The oncologist is in another building at a tumour board.
1. List the immediate actions in priority order and explain the reasoning behind each.

Immediate actions (priority order):
- STOP the infusion immediately - do not flush. Every additional millilitre of vesicant increases tissue injury.
- Leave the cannula in place - it may be needed for aspiration and antidote instillation; removing it prematurely can lose access.
- Aspirate residual drug/fluid per protocol if trained and ordered.
- Call for help - second nurse, charge nurse, and page the oncologist (or on-call covering clinician) for orders.
- Retrieve and open the vesicant kit; follow the kit's antidote and procedure instructions.
- Elevate the limb and apply cold compresses for doxorubicin (anthracycline = cold, not warm).
- Mark the perimeter of the affected area with a pen and time-stamp it.
- Document time, drug, volume, catheter, symptoms, interventions, and who was notified.
Reasoning: Anthracyclines are powerful vesicants; injury can progress over days to necrosis. Speed and not flushing are the highest-yield actions. Cold causes vasoconstriction, limiting spread. Marking allows objective tracking of progression.
Honest limitation: The nurse should say plainly that she has not used the kit before and ask a trained colleague to assist - this is safer than improvising. She should also report the event through the incident system afterward.
2. What follow-up and system-level lessons should be addressed after the acute event?
Read the worked answer
Patient follow-up:
- Ongoing assessment at scheduled intervals (e.g., 24, 48, 72 hours and beyond) for pain, blistering, erythema, and necrosis.
- Plastic surgery/dermatology referral if injury progresses.
- Analgesia and wound care as needed; prepare the patient for possible delayed worsening.
- Documented patient education about warning signs and who to call.
System-level lessons (quality improvement):
- Competency gap - the nurse had never used the vesicant kit. Annual vesicant/extravasation competency and mock drills should be mandatory for anyone administering vesicants.
- Access choice - a 22-gauge antecubital catheter for a vesicant is suboptimal; consider central access or a larger, well-positioned catheter per policy. Review whether antecubital placement is appropriate for this regimen.
- Kit accessibility and familiarity - kit location known and contents reviewed at onboarding.
- Escalation pathway - the oncologist being off-site should not delay antidote orders; confirm an on-call backup exists.
- Incident reporting and review - file a report, review at quality meeting, and feed changes back to staff.
Framing: The acute response protects the patient now; the system review protects the next patient. Both are professional obligations, and the nurse should participate openly rather than defensively.
