Dexmedetomidine is known to protect against ischemia-reperfusion (IR) in various organs; however, the mechanisms of dexmedetomidine in the liver remain unclear. We investigated whether dexmedetomidine preconditioning leads to hepatic protection and whether nitric oxide was associated with this protective mechanism by employing N-nitro-l-arginine methyl ester (l-NAME), a nitrous oxide synthase inhibitor.
