Upper airway edema: An anaphylactoid reaction to succinylcholine?

Abstract

Succinylcholine (SCh) was reported to cause histamine release in 1957 when skin reactions were observed in four patients. Since then, at least 12 additional cases of hypersensitivity to the drug have been described. This report presents a case of probably SCh-induced upper airway edema in a patient with bronchial asthma and known penicillin allergy.
