Brief summary
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.
Interventions
DEVICEHuawei bracelet
Huawei bracelet was used to continuously record maternal respiration, heart rate, temperature and sleep data, and then calculate maternal circadian rhythm state

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Incidence of moderate and severe pain after cesarean section | From ending of the surgery to 24hours after cesarean section | number rating scale (NRS) for pain (0=no pain to 10=worst pain) \>4 |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pain intensity durig 12 to 24 hours after surgery | From 12 hours after cesarean section to 24 hours after cesarean section | number rating scale (NRS) for pain (0=no pain to 10=worst pain) |
| Pain intensity durig 0 to 6 hours after surgery | From ending of the surgery to 6 hours after cesarean section | number rating scale (NRS) for pain (0=no pain to 10=worst pain) |
| Heart rate variability | From the time of inclusion in the study until the patient's postoperative discharge, assessed up to 1 week | Heart rate variability recorded by Huawei bracelet |
| Pain intensity durig 6 to 12 hours after surgery | From 6 hours after cesarean section to 12 hours after cesarean section | number rating scale (NRS) for pain (0=no pain to 10=worst pain) |
| Variability of patients' activity | From the time of inclusion in the study until the patient's postoperative discharge, assessed up to 1 week | Variability of patients' activity recorded by Huawei bracelet |
