Agent-selective effects of volatile anesthetics on GABAA receptor-mediated synaptic inhibition in hippocampal interneurons.

abstract：:The pharmacokinetics and protein binding of propofol were studied in ten patients with cirrhosis and in ten control patients undergoing elective surgery. All patients received 2.5 mg.kg-1 propofol as an intravenous bolus injection for the induction of anesthesia. Whole blood propofol concentrations were measured at in...
