Abstract

To determine the effect of anesthetics on liver relaxation times in rat, two experiments were performed. In the first experiment, normal and protein-depleted rats underwent total hepatectomy under ether anesthesia or following decapitation. In the second experiment, livers were excised from normal rats under ketamine or pentobarbital anesthesia, or following decapitation. Hepatic T1 and T2 were measured for all animals using a RADX 10 MHz spin analyzer. Ketamine produced T1 values significantly different from decapitation. Ketamine, pentobarbital, and ether in normal animals all produced T2 values significantly different from decapitation. It is apparent that anesthetization of rats prior to in vitro measurement of hepatic relaxation times is not equivalent to decapitation; nor are the anesthetics examined equivalent to one another.
