The influence of diaphragmatic position on abnormal gas exchange has been examined to investigate the theory that the impairment in gas exchange in anaesthetized man is caused by disturbance of diaphragmatic mechanics, resulting in abnormalities of d

The effect of changes in muscle blood flow on the rate of recovery from neuromuscular block produced by pancuronium was investigated in dogs, and were shown to be independent variables. The significance of this finding in relation to recent work on b

Previous studies have shown a dose-related effect of a number of general anaesthetic agents on the early cortical waves in the auditory evoked response (AER). In this study the effect of surgical stimulation on these waves was examined in 11 patients

A technique for measuring cardiac output which depends on the uptake of an inert soluble gas from the lungs has been evaluated during anaesthesia. A respiratory mass spectrometer has been used to follow the concentrations of argon and freon-22 during

A method is described for measuring metabolic gas exchange during general anaesthesia using a respiratory mass spectrometer, a mixing box and two inert tracer gases. Measurement of inspired and expired minute volume is possible to within 2% oxygen co

The auditory evoked response (AER) has been studied in six patients before the induction of general anaesthesia, during anaesthesia with nitrous oxide in oxygen and mechanical ventilation, then with a stepwise increasing rate of infusion of Althesin

The concentration of carbon dioxide in end-tidal gas was compared with the tension in arterial or superior vena caval blood during thoracotomy in twelve patients. In six adults requiring pulmonary resection, one-lung anaesthesia did not change the di

We have examined the effects of isoflurane (0.6–2.9% end-tidal) on the auditory evoked response (AER) in six patients before elective surgery. Isoflurane produced significant dose-related changes in the AER: reductions in amplitude and increases in

The effects of increasing concentrations of halothane and enflurane on selected components of the auditory evoked response were studied in 12 patients; six received halothane and six enflurane. After the induction of anaesthesia with thiopentone, ana
