Changes in PTI, WLI, MAP, HR and SpO2. PTI: pain threshold index; BWI: brain wavelet index; MAP: mean arterial pressure; HR: heart rate; SpO2: pulse oxygen saturation. T0: baseline values, T1: before GA induction; T2: after intubation; T3: after incision; T4: 5 min after carbon dioxide pneumoperitoneum; T5: the end of operation; T6: 5 min after extubation in the operation room. *: unpaired Student’s t-test, p < 0.05 between groups
