RESUMO
Nitrous oxide has a long history of successful use in inhalational anaesthesia. Nevertheless questions are being raised over possible deleterious effects which may complicate its routine use. As more potent volatile agents have become available, compressed air/oxygen mixtures are gradually replacing nitrous oxide as a carrier gas in inhalational anaesthesia. We recommend that compressed air be installed on all anaesthetic machines and that in future, machines be designed so as to make it impossible to administer both nitrous oxide and air simultaneously (AU)

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.(AU)

The use of compressed air/oxygen mixtures to replace nitrous oxide/oxygen in general anaesthesia is investigated in 378 patients. There was no prolongation of recovery time nor instances of awareness under anaesthesia. The cost of general anaesthesia, using compressed air/oxygen mixtures was BDS$10.05 per patient while the cost of using nitrous oxide/oxygen mixtures was BD$20.11 per patient (AU)

An investigation was carried out to establish if the intravenous injection of gallamine triethiodide 40mg in an anaesthetized patient breathing spontaneously, was sufficient to depress ventilation as judged by a rise Pa co2. Fifty women undergoing minor gynaecological surgery were divided into two equal groups at random. One group received thiopentone, nitrous oxide, oxygen and trichlorethylene anaesthesia. The other group received in addition gallamine 40 mg. On examination of blood gases, no statistical difference could be demonstrated between the two groups. It was concluded that this practice does not depress spontaneous ventilation.(AU)
