The halothane-ether azeotrope 3 per cent in oxygen has been administered to twenty patients already adequately anaesthetized with halothane. Respiration was artificially maintained between 8-1Q L. per min., using non-return breathing equipment.Systolic blood pressures were frequently recorded by sphygmomanometry and vasculometry. The amplitude of the peripheral pulse was continuously displayed by a simple vasculometer and vasculograms were obtained at frequent intervals.It was observed that the azeotrope in most patients caused a progressive decline in blood pressure which reached profound levels in five patients. The hypotension was associated with a decrease in the amplitude of the pulse wave in all cases and circulatory stasis with cyanosis was seen in six cases.It is concluded that the administration of mixtures of either and halothane is illogical and the physical and pharmacological reasons for this conclusion are presented.It is suggested that halothane by itself in oxygen is fully capable of providing all the necessities of safe and effective anaesthesia. |
