Circulatory effects of controlled arterial hypotension with trimetaphan during nitrous oxide-halothane anaesthesia.
Studies were made in ten patients of the circulatory changes occurring during the administration of trimetaphan to produce hypotension during nitrous oxide/halothane anaesthesia. Ventilation was spontaneous throughout. There were significant falls in arterial pressure and peripheral resistance. Cardiac output was relatively unaffected. Heart rate sometimes increased and this was associated with...
متن کاملMetabolic effects of induced hypotension with trimetaphan and sodium nitroprusside.
In two groups of patients undergoing induced hypotension with sodium nitroprusside or trimetaphan blood concentrations of lactate, pyruvate and standard bicarbonate did not differ significantly between the groups. In the nine patients who received trimetaphan there was a progressive, but statistically non-significant, decrease in mean lactate. Nitroprusside (15 patients) was associated with a s...
متن کاملCrisis management during anaesthesia: hypotension.
BACKGROUND Hypotension is commonly encountered in association with anaesthesia and surgery. Uncorrected and sustained it puts the brain, heart, kidneys, and the fetus in pregnancy at risk of permanent or even fatal damage. Its recognition and correction is time critical, especially in patients with pre-existing disease that compromises organ perfusion. OBJECTIVES To examine the role of a prev...
متن کاملHypotension during subarachnoid anaesthesia: haemodynamic effects of ephedrine.
We have compared the haemodynamic effects of ephedrine alone with ephedrine and colloid for the treatment of hypotension produced by subarachnoid anaesthesia in 30 patients aged 60-90 yr with fractures of the neck of femur. Group one received ephedrine as an initial bolus dose of 0.2 mg kg-1 followed by an infusion of 0.5 mg kg-1 h-1. Group two received ephedrine and colloid (polygeline, Haemac...
متن کاملCerebral circulatory and metabolic effects of hypotension produced by deep halothane anaesthesia.
Hypotension to a mean blood pressure of 33 mmHg for periods of 70 to 187 minutes was induced by increasing the inspired halothane concentration in 11 baboons which were already anaesthetized with 0·5% halothane, nitrous oxide, and oxygen. During hypotension, cerebral blood flow, measured by Xenon clearance and by a carotid electromagnetic flowmeter, decreased by more than half, and sagittal sin...
