Pneumonitis, Extravasation, and Local Therapy Emergencies
Key Takeaways
- New cough, dyspnea, hypoxia, chest tightness, fever, or declining exercise tolerance during cancer therapy requires prompt assessment for pneumonitis, infection, embolism, or progression.
- Extravasation is a time-sensitive local emergency, especially with vesicants that can cause tissue necrosis and functional loss.
- Radiation, surgery, ablation, and interventional procedures can cause urgent complications such as bleeding, infection, airway edema, perforation, or organ inflammation.
- Nursing actions include stopping harmful exposure, focused assessment, site protection, ordered antidotes or compresses, symptom monitoring, and escalation.
- Patient education should identify respiratory red flags, infusion site symptoms, wound concerns, and when to seek emergency care.
Pneumonitis, Extravasation, and Local Therapy Emergencies
Not every emergency is systemic at first. Some begin in the lungs, a vein, a radiation field, a surgical site, or a procedure area. The RN's task is to notice patterns early and prevent small injuries from becoming respiratory failure, tissue necrosis, sepsis, hemorrhage, or permanent functional loss.
Pneumonitis
Pneumonitis is inflammation of lung tissue and may be caused by immune checkpoint inhibitors, targeted therapies, antibody drug conjugates, chemotherapy, radiation, infection, aspiration, or combined treatments. Symptoms include new or worsening cough, dyspnea, chest tightness, fever, fatigue, hypoxia, or reduced activity tolerance. It can mimic pneumonia, pulmonary embolism, heart failure, anemia, anxiety, or disease progression. Because the differential is broad and risk is high, new respiratory symptoms during cancer therapy deserve prompt escalation.
| Respiratory finding | Nursing concern |
|---|---|
| New dry cough during immunotherapy | Possible immune-related pneumonitis |
| Dyspnea with hypoxia | Needs urgent evaluation and oxygen support |
| Fever plus cough | Infection, pneumonitis, or both |
| Pleuritic pain | Consider pulmonary embolism or infection |
| Rapidly rising oxygen need | Emergency response and possible transfer |
Nursing actions include vital signs, pulse oximetry, lung assessment, activity tolerance, medication and treatment review, infection screening, and provider notification. Apply oxygen as indicated, prepare for imaging or labs, and reinforce that patients should not self-start leftover antibiotics or steroids. Severe pneumonitis may require hospitalization, high-dose corticosteroids, treatment hold, bronchoscopy, or specialty consultation.
Extravasation
Extravasation is leakage of a drug into surrounding tissue. Vesicants can cause blistering, necrosis, tendon or nerve injury, and loss of function. Irritants may cause pain or inflammation without the same necrotic potential, but all suspected events require action. Early signs include burning, stinging, pain, swelling, erythema, blanching, coolness, lack of blood return, resistance during flushing, leaking at the site, or slowed infusion.
If extravasation is suspected, stop the infusion immediately. Leave the catheter in place until policy directs removal because aspiration of residual drug or antidote administration may be needed. Disconnect tubing, aspirate if directed, notify the provider, mark and measure the site, photograph if policy allows, elevate the limb, apply warm or cold compresses according to drug-specific guidance, and administer antidote if ordered. Do not apply heat or cold randomly; the correct choice depends on the agent. Document drug, concentration, estimated volume, site, symptoms, interventions, patient response, education, and follow-up plan.
Radiation and Procedure Emergencies
Radiation emergencies can include airway edema after head and neck treatment, severe esophagitis with dehydration, radiation pneumonitis, spinal cord risk, skin breakdown with infection, cystitis, enteritis, and bleeding. Surgical and interventional complications may include hemorrhage, infection, wound dehiscence, perforation, bile leak, urinary obstruction, post-ablation syndrome, pneumothorax, or embolization complications. Nurses should monitor pain that is out of proportion, fever, drainage, swelling, crepitus, shortness of breath, hypotension, tachycardia, and new neurologic deficits.
Patient Education
Teach patients to call for new shortness of breath, persistent cough, fever, chest pain, oxygen saturation decline if home monitoring is used, painful or blistering infusion sites, spreading redness, drainage, wound opening, uncontrolled pain, vomiting, or bleeding. For extravasation follow-up, patients should know that tissue injury can evolve over days and must be reported promptly. For radiation and procedures, clear discharge instructions, contact numbers, and teach-back are part of emergency prevention.
Follow-Up After Local Injury
Local therapy emergencies need follow-up because damage may evolve after the patient leaves the chair, scanner, operating room, or procedure suite. For pneumonitis, ask whether the patient can speak full sentences, climb usual stairs, sleep flat, and maintain usual oxygen saturation. For extravasation, provide site-specific instructions, expected follow-up calls, and symptoms that require urgent reassessment such as increasing pain, blistering, numbness, reduced movement, drainage, or spreading redness.
For procedure sites, compare pain and drainage with discharge instructions and assess anticoagulant use. Good nursing documentation includes measurements, photos if allowed, patient education, provider notification, and the exact plan for reassessment.
