Cardiac output changes with altered acid-base status during methoxyflurane anaesthesia.
THE PIYBPOSE OF this study was to determine the effects upon cardiac out-put of alterations in acid-base states during methoxyflurane anaesthesia in dogs. Studies of varied acid-base states on cardiac functions have been described in v i tro 1 and in v ivo. ~.3 A clear understanding of cause and effect relationships has been prevented by disparity of results, lack of correlation with surface ar...
متن کاملRespiratory and Metabolic Changes during Methoxyflurane and Halothane Anaesthesia.
Respiratory and metabolic changes were studied in twenty normal children during inhalation of 1.5 per cent methoxyflurane or halothane. Both agents caused a significant reduction in pH, and this acidosis was entirely due to a raised Pco2. It was calculated that after 30 minutes anaesthesia the approximate arterial tension of methoxyflurane was 0.3 per cent and that of halothane 0.8 per cent. Si...
متن کاملChanges in fetal acid base status during intravascular transfusion.
Umbilical venous pH, PCO2, PO2, and base excess was measured immediately before and after 72 intravascular transfusions in 34 fetuses with erythroblastosis fetalis. In 67 uncomplicated transfusions, infused adult blood led to a mean (95% confidence intervals) fall in pH (0.037, CI 0.029 to 0.044) and base excess (2.03, CI 1.61 to 2.45) and a mean rise in PCO2 (0.24 kPa, CI 0.13 to 0.35). These ...
متن کاملOxalic acid excretion after methoxyflurane and halothane anaesthesia.
METttOXYFLURANE IS A general anaesthetic that has been implicated in the production of postoperative renal dysfunction. 1-6 The precise mechanism is unknown, but the finding of many oxalate crystals in the renal tubules, 5,6 and large amounts of oxalic acid in the urine of patients who develop renal failure after methoxyflurane anaesthesia s has suggested the possibility that oxalic acid may be...
متن کامل[Effect of epinephrine on the human heart during methoxyflurane anaesthesia].
THE EFFECTS Of epinephrine on the dog's heart during methoxyflurane anaesthesia have been reported2 ,2 According to Bamforth, epinephrine can cause fibrillation of the dog's heart during deep anaesthesia at a potentiality about equal to that of chloroform, but much less than that of cyelopropane. On the other hand, Van Poznak found that arrhythmias produced by intravenous epinephrine in the con...
