Allergic reactions and anaphylaxis during anaesthesia

Abstract

Although allergic reactions during anaesthesia are rare, it may have potentially life threatening consequences when anaphylaxis develops. Should a patient have a possible reaction under anaesthesia, it is important to identify an offending agent to prevent re-exposure during subsequent procedures. This review aims to identify common causes of anaphylaxis during anaesthesia, how to deal with the emergency, and how to follow up the at-risk patient.
