Factors contributing to a reduction in anaesthetic mortality.

A substantial improvement in anaesthetic mortality has been noted at Coronation Hospital; the reasons for this are discussed. The factors considered include lethal circumstances associated with the use of suxamethonium and fentanyl; improved ventilation monitoring and postanaesthetic surveillance; a technique in the resuscitation of bleeding patients aimed at conserving the intravascular contents; and the management of dehydrated patients. The dangers associated with the induction of anaesthesia in a head-up position are considered and alternated means are suggested.
