Figure 1. Cranial temperature in dogs assigned to one of three study groups (n = 7 in each): a reference group maintained at a target temperature of 37 degrees Celsius, a 38 degrees Celsius group, or a 39 degrees Celsius group. Dogs were maintained at the target temperature for a minimum of 20 min before, during, and 1 h after the ischemic insult. Reported values are the averages of the left and right cranial temperature measurements. Shaded area = the 12.5-min period of complete ischemia; vertical bars = 1 SD. Standard deviations are not represented during the ischemic period.
