It has been postulated that nitric oxide (NO) is a neurotransmitter involved in consciousness, analgesia, and anesthesia. Halothane has been shown to attenuate NO-mediated cyclic guanosine monophosphate accumulation in neurons, and a variety of anesthetic agents attenuate endothelium-mediated vasodilation, suggesting an interaction of anesthetic agents and the NO-cyclic guanosine monophosphate pathway. However, the exact site of anesthetic inhibitory action in this multistep pathway is unclear. The current study examines effects of volatile and intravenous anesthetic agents on the enzyme nitric oxide synthase (NOS) in brain.
