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 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 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 کاملThe effects of nitrous oxide on controlled hypotension during low flow anesthesia.
BACKGROUND AND OBJECTIVES We investigated the effect of Nitrous Oxide (N2O) on controlled hypotension in low-flow isoflurane-dexmedetomidine anesthesia in terms of hemodynamics, anesthetic consumption, and costs. METHODS We allocated forty patients randomly into two equal groups. We then maintained dexmedetomidine infusion (0.1 μg.kg(-1).min(-1)) for 10 minutes. Next, we continued it until th...
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...
