Narcosis, blood glucose, plasma insulin and renin concentrations: experimental research with Althesin, thiopental and ketamine.

In the rat, narcotic doses of Althesin injected intraperitoneally did not modify blood glucose concentration nor plasma insulin concentration. On the contrary, a reduction of blood glucose concentration, associated with an increase of plasma insulin concentration was observed when narcotic doses of thiopental and ketamine were administered. Plasma renin concentrations decreased after injection of Althesin and thiopental but increased after injection of ketamine.
