Nursing care for anaphylaxis

The nurse works within the emergency team and follows the facility's anaphylaxis protocol. Treatment begins from the clinical pattern rather than waiting for a laboratory result or for every possible symptom to appear.

The initial assessment checks airway swelling or voice change, breathing effort and wheeze, pulse and blood pressure, skin appearance, alertness, and symptoms affecting the stomach or bowel. Nurses also identify the likely trigger, when exposure occurred, medicines already given and any relevant allergy history.

Repeated observations matter because the reaction can change quickly. A person may have dangerous breathing or circulation problems without hives, so skin findings are only one part of the assessment.

Nursing actions commonly include activating emergency support, helping position the patient safely, administering intramuscular epinephrine as authorised, providing oxygen, obtaining vascular access and preparing fluids or additional medicines ordered by the clinician. The team also prepares airway equipment if swelling or breathing difficulty progresses.

The nurse documents symptom onset, suspected exposure, observation findings, medicine doses, administration sites, response to treatment and communication with the patient or family. Clear timing supports clinical decisions if another dose or higher-level airway care is needed.

New throat tightness, voice change, worsening wheeze, falling blood pressure, faintness, confusion or reduced responsiveness prompts immediate escalation. Monitoring continues after improvement because symptoms may recur and the required observation period depends on reaction severity, treatment response and clinical risk factors.

Before discharge, ask the team to explain the suspected trigger, medicines given, warning signs of recurrence and where to seek urgent help. Patients prescribed an epinephrine injector should receive hands-on technique teaching, a written action plan and guidance on carrying and storing the device. Follow-up may include allergy assessment and review of avoidable triggers.
