Anaphylaxis and anaphylactoid reactions. A guide to prevention, recognition, and emergent treatment.

摘要

Anaphylaxis and anaphylactoid reactions are adverse immunologic responses that require early intervention to prevent life-threatening consequences. The initial symptoms, such as nasal congestion or pruritus, can quickly progress to cardiac collapse or asphyxiation. In this article, Drs Rusznak and Peebles discuss the mechanisms of these reactions, common causative agents, preventive strategies, recognition, and treatment.
