title: Should air-oxygen replace nitrous oxide-oxygen in general anaesthesia?
abstract: The use of compressed air-oxygen mixtures to replace nitrous oxide-oxygen in general anaesthesia was investigated in 378 patients. There were neither prolongations of recovery time nor instances of awareness under anaesthesia. The cost of general anaesthesia using compressed air-oxygen was about half that for nitrous oxide-oxygen mixtures.
