Perioperative anaphylaxis: Management and risk reduction strategies in 2024

The Australian and New Zealand College of Anaesthetists (ANZCA) reports anaphylaxis is the most common cause of death associated with anaesthesia in Australia, and the incidence is rising. Anaphylaxis is a life-threatening event that without early recognition and prompt crisis management results in morbidity and mortality. Trigger agents for anaphylaxis in the Australian perioperative environment are commonly neuromuscular blocking agents, antibiotics and chlorhexidine. Many cases of mild to life threatening anaphylaxis (grades 1–3) in Australia are under-reported.The Australian Perioperative Anaphylaxis guidelines have recently beenupdated to optimise management of patients experiencing anaphylaxisduring anaesthesia. The Australian Therapeutic Goods Administration (TGA)also launched an initiative in March 2023 to reduce perioperative anaphylaxis,withdrawing 44 products containing pholcodine due to its association withanaphylactic reactions during general anaesthesia.
