Effect of ketamine on transmission in sympathetic ganglia
British Journal of Anaesthesia
|April 1, 1980
Abstract:
The effect of ketamine on sympathetic ganglion transmission has been studied using the guineapig isolated hypogastric nerve-vas deferens preparation. Ketamine produced a dose-dependent depression in the response to preganglionic stimulation (IC50 2.05 X 10--4 mol litre--1). No change in the response to postganglionic stimulation was recorded. The anti-cholinergic activity of ketamine was confirmed using the frog isolated rectus abdominis.
