Anaphylaxis
ADU-02
Diagnosis
Hypotension, bronchospasm, high peak-airway pressures, decreased breath sounds, tachycardia, urticaria
Call for help
- Ask: "Who will be the crisis manager?"
- Crisis manager designates checklist reader
Give EPINEPHrine bolus
- Repeat bolus with increasing dose as needed
- Consider EPINEPHrine infusion
Establish/secure airway
- Turn FiO2 to 100% or start supplemental oxygen
Remove potential causative agents
Give fluid bolus
Consider...
- Minimize volatile anesthetics if patient remains unstable
- Consider albuterol as adjunctive therapy for bronchospasm unresponsive to EPINEPHrine
- Vasopressin bolus and/or infusion for patients with hypotension unresponsive to EPINEPHrine
- Terminate procedure
- Once hemodynamically stable:
- Supplemental treatment with diphenhydrAMINE and corticosteroids
- Tryptase level: Check within first hour, repeat at 4 and 18-24 hours
