  1. Values are mean ± SD. T0: before operation; T4: the end of operation; T5: 3 h after operation. S1: spinal anesthesia with operation time ≤ 30 min; S2: spinal anesthesia with operation time > 30 min; PF1: propofol-fentanyl intravenous anesthesia with operation time ≤ 30 min; PF2: propofol-fentanyl intravenous anesthesia with operation time > 30 min
