Anaphylaxis during anaesthesia. Results of a two‐year survey in France

Between January 1, 1997 and December 31, 1998, 467 patients were referred to one of the allergo‐anaesthesia centres of the French GERAP (Groupe d’Etudes des Réactions Anaphylactoïdes Peranesthésiques) network and were diagnosed as having anaphylaxis during anaesthesia.

Latex was less frequently incriminated (12.1%) than in previous reports. A significant difference was observed between the incidence of anaphylactic reactions observed with each neuromuscular blocking agent and the number of patients who received each drug during anaesthesia in France throughout the study period (P
