Drugs and other agents involved in anaphylactic shock occurring during anaesthesia. A French multicenter epidemiological inquiry.
An epidemiological inquiry was carried out in departments of anaesthesia and immunology in French University and General Hospitals, as well as among those who were already known to have an allergo-anaesthesia outpatient clinic. This inquiry aimed to find out how many patients had undergone diagnostic investigations after as well as an anaphylactoid reaction during an anaesthetic in 1990 and 1991, as well as the demographic data, the kind of assessment, the accident mechanism and the drugs involved. Twenty-one French centres replied to the questionnaire and a series of 1,585 patients tested over a two-year period was thus collected. There were three female patients to one male. The reactions occurred mostly in the adult (80%), but 9% were observed in children. Allergological tests for IgE-dependent anaphylaxis were the skin tests (21 centres), combined with radioimmunological assays of specific serum antibodies to muscle relaxants (10 centres), propofol (9 centres), latex (5 centres), leukocyte histamine release (9 centres) and human basophil degranulation test (4 centres). The criteria for a positive result were the same for all centres. Among these 1,585 patients, 813 were recognized as having had a reaction of immunological origin (52%). The substances involved were identified in these 813 patients as being muscle relaxants (70%), latex (12.6%), hypnotics (3.6%), benzodiazepines (2.0%), opioids (1.7%), colloids (4.7%), and antibiotics (2.6%). Suxamethonium was responsible for 43% of the IgE-dependent reactions involving a muscle relaxant, vecuronium for 37%, pancuronium for 13%, alcuronium for 7.6%, atracurium for 6.8% and gallamine for 5.6%.(ABSTRACT TRUNCATED AT 250 WORDS)
