Metabolic 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 کاملCardiovascular actions of trimetaphan nitroprusside. Comparison with sodium nitroprusside in greyhounds.
Trimetaphan nitroprusside (TNP) is a new potent hypotensive agent developed to induce and maintain decreases in arterial pressure unaccompanied by resistance. This study investigated its properties and compared them with those of sodium nitroprusside (SNP) in anaesthetized greyhounds. The mean dose response to TNP was obtained by measuring haemodynamic changes in five dogs. With increasing dose...
متن کاملEffect of sodium nitroprusside and trimetaphan on neuromuscular transmission in the frog.
In summary, it appears from this and other studies that trimetaphan has the potential for producing neuromuscular blockade when used in large doses or when combined with other muscle relaxants. The mode of action appears to be principally that of non-depolarizing neuromuscular blockade. Sodium nitroprusside, on the other hand, even in doses beyond these accepted clinically, does not affect neur...
متن کاملIntracranial pressure changes in neurosurgical patients during hypotension induced with sodium nitroprusside or trimetaphan.
Intracranial pressure has been measured in 45 patients undergoing neurosurgery during the induction of deliberate hypotension using either sodium nitroprusside or trimetaphan. A statistically significant increase in intracranial pressure (ICP) occurred during the early stages of the infusion of nitroprusside in normocapnic patients. A non-significant increase in ICP was obtained in hypocapnic p...
متن کاملElectrical activity of the cerebral cortex during induced hypotension in man. A comparison of sodium nitroprusside and trimetaphan.
During the routine use of controlled hypotension the electroencephalogram (EEG) and mean arterial pressure (MAP) were monitored in 20 normotensive patients (younger than 70 years-of-age) receiving either trimetaphan (TMP) or sodium nitroprusside (SNP). The reduction in MAP was quicker and greater with SNP. Significant differences in EEG voltage between the two agents were seen in the range 55-4...
