Laryngospasm and bronchospasm add to the hazards associated with anaesthesia in both man and animals. Of one thousand anaesthetic deaths in Great Britain and Ireland reported to the Association of Anaesthetists between 1949 and 1955, it was found that fifty deaths were due to respiratory obstruction of one sort or another (CitationEdwards et al., 1956). It has been stated that laryngeal spasm is perhaps potentially the most frequent source of respiratory obstruction during general anaesthesia in man (CitationGillespie, 1963).
