Anaesthesia for bronchoscopy: examination of a standard technique.

An anaesthetic technique for bronchoscopy is described, based on increments of methohexitone given in strict relation to body weight and time, suxamethonium being used to produce relaxation. There was no awareness in the 75 patients studied, while the recovery was rapid and unrelated to the duration of bronchoscopy. The efficacy of small aliquots of lignocaine in reducing injection pain was the same whether given before, or mixed with, the initial methohexitone injection. Other sequelae relating to the anaesthetic technique were minimal.
