Fig. 1. Intraoperative changes in tympanic membrane temperature. Data are expressed as mean ± SD. Comparisons at Lowest and Ex among the three groups were performed using analysis of variance followed by the Dunnett test. *P < 0.05 versus the control group. AMR 15 (open circle) = a group of patients who re-ceived 15 μg · kg−1· min−1amrinone with a 1.0-mg/kg loading dose of amrinone; ReAMR (open triangle) = a group of patients who received 5 μg · kg−1· min−1amrinone with a 1.0-mg/kg loading dose of amrinone twice, at the start of cooling and rewarming; Control (solid circle) = a group of patients who received no amrinone; Cooling = at the start of active cooling; Rewarming = at the start of active rewarming; Lowest = at the time when tympanic temperature reached the lowest temperature; Ex = at extubation.
