About this trial

Use huawei wristwatch to record maternal rhythm status and record the VAS score after cesarean section under combined spinal-epidural anesthesia. Based on this study the investigators intend to explore the correlation between maternal circadian rhythm status and postoperative pain after cesarean section.
