[Anaphylactoid complications due to the use of anesthetic products and adjuvants. Apropos of 18 cases].

Eighteen grave anaphylactic accidents arising during induction or during anaesthesia, are analysed. By order of frequency, the clinical signs are cutaneous manifestations (70 p. 100 of the cases), bronchospasm (65 p. 100), cardiovascular collapse (45 p. 100). In four cases, cardiac arrest occurred. The course was always favourable, with no after-effects. Immuno-allergic tests enabled one to make the diagnosis of true anaphylaxis in eight cases (seven shocks due to succinylcholine, one due to propanidide), of non specific histamine-liberation in five cases; in the other cases, it was impossible to express an opinion.
