Relationships 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...
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 کاملMyocardial blood flow and oxygen consumption during halothane-nitrous oxide anaesthesia for coronary revascularization.
The effects of halothane on myocardial blood flow and myocardial oxygen balance were studied in seven male patients with stable angina and normal left ventricular function. Patients were receiving maintenance doses of beta-receptor antagonists and underwent coronary artery bypass surgery. Anaesthesia consisted of halothane and 50% nitrous oxide in oxygen. Halothane decreased myocardial blood fl...
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 کاملImpairment of oxygen transfer in the lung by increasing oxygen concentration during halothane and trichloroethylene anaesthesia.
Two groups of 10 patients were studied during artificial ventilation with a mixture of oxygen, nitrogen and either halothane or trichloroethylene. Arterial blood and respiratory gas smapling was performed at FIO2 values of 0.33, 0.5 and 0.75. The efficiency of oxygen transfer, expressed as the difference between pulmonary end-capillary and arterial oxygen content, was found to decrease progress...
