[Allergy to suxamethonium. Case report].

The authors describe a clinical case of an allergy to suxamethonium (succinylcholine) chloride which prompted--a posteriori--an allergological work-up. This, in turn, demonstrated all the factors favoring histamine-release: atopic predisposition, tendency of nonspecific histamine-release, and real allergy to the muscle relaxant. This study has enabled the induction of anaesthesia without any problems, by avoiding the allergens through preventive therapy.
