UNASSIGNED: @entity221 is a common complication during anesthesia of bears, and it can be life threatening. The objective of this study was to evaluate the effectiveness of active cooling on core body temperature for treatment of @entity221 in anesthetized @entity16745 ( @entity16745 ). In addition, body temperature after reversal with @entity22571 was also evaluated. Twenty-five adult and subadult @entity16745 were captured with a combination of @entity25171 - @entity25170 and @entity4763 or @entity8998 . A core temperature capsule was inserted into the bears' stomach or 15 cm into their rectum or a combination of both. In six bears with gastric temperatures >= 40.0  C, an active cooling protocol was performed, and the temperature change over 30 min was analyzed. The cooling protocol consisted of enemas with 2 L of water at approximately 5  C/100 kg of body weight every 10 min, 1 L of intravenous fluids at ambient temperature, water or snow on the paws or the inguinal area, intranasal @entity26 supplementation, and removing the bear from direct sunlight or providing shade. Nine bears with body temperature >39.0  C that were not cooled served as control for the treated animals. Their body temperatures were recorded for 30 min, prior to administration of reversal. At the end of the anesthetic procedure, all bears received an intramuscular dose of @entity22571 . In 10 bears, deep rectal temperature change over 30 min after administration of @entity22571 was evaluated. The active cooling protocol used in hyperthermic bears significantly decreased their body temperatures within 10 min, and it produced a significantly greater decrease in their temperature than that recorded in the control group.
