Innovar as an adjunct to nitrous oxide, oxygen, curare anaesthesia.
WrTH THE INCREASING concern many anaesthetists are feeling toward the rather routine use of halogenated hydrocarbons, we felt it worthwhile to develop a simple technique to avoid these agents in major surgical procedures. The well recognized use of nitrous oxide (N20) plus oxygen (O2), muscle relaxants and hyperventilation provides adequate operating conditions for certain procedures, i.e. ches...
متن کاملInspiratory to end-tidal oxygen difference during nitrous oxide anaesthesia.
In order to evaluate the value of the inspiratory to end-tidal oxygen concentration difference (Io2-E'o2) as a monitor during general anaesthesia, we studied 40 orthopaedic patients allocated randomly to four groups: anaesthesia with enflurane or isoflurane in nitrous oxide with either spontaneous or controlled ventilation. (Io2-E'o2) followed an asymptotically increasing curve because of decre...
متن کاملEffects of general anaesthesia on the intraocular pressure in man. Trichloroethylene in nitrous oxide and oxygen.
The effect of TCE on the intraocular pressure was investigated in eight patients under thiopentone nitrous oxide/oxygen anaesthesia, using a muscle relaxant (pancuronium bromide). Pulmonary ventilation was controlled and the end-tidal carbon dioxide was maintained at 5 per cent. In every patient the intraocular pressure was observed to rise as TCE was administered and then to return to the init...
متن کاملCirculatory effects of pentazocine and pethidine during general anaesthesia with nitrous oxide, oxygen and halothane.
Pentazocine 30 mg and pethidine 30 mg were given intravenously to two groups of patients receiving general anaesthesia with nitrous oxide, oxygen and halothane. The injections were repeated after 10 minutes. The effects on cardiac output, arterial blood pressure, heart rate and central venous pressure were measured. Both drugs caused a transient fall (approximately 20 per cent) in cardiac outpu...
متن کاملRelationships between inspired oxygen concentration and venous admixture during nitrous oxide-oxygen-halothane anaesthesia.
The inspired oxygen concentration (F/O2) was changed on 43 occasions at about 30-min intervals in 13 patients during artificial ventilation with mixtures of nitrous oxide (N2O), oxygen and halothane. Ventilator settings remained unchanged for each patient and at the end of each period, samples of arterial and central venous blood (and, in six patients, pulmonary arterial blood) and inspired and...
