*P<0.05: The comparison is significant between the two groups. ^†P<0.05 significant compared to the preoperative reading within the same group. T0: the preoperative value, T1: 5^th min after induction, T2: directly before intramyometrial vasopressin administration, T3: 15^th min after vasopressin administration, T4: 30^th min after vasopressin administration, T5: 45^th minute after vasopressin administration, T6: 60th min after vasopressin administration, T7: directly at the end of surgery; T8: 60th min in the postoperative care unit
