Effect of S-ketamine in Cesarean Section Combined Anesthesia
Study Details
Study Description
Brief Summary
To compare the anti-hyperalgesia effect between S-ketamine with placebo for Maternal receiving elective Cesarean Section under Combined spinal and epidural analgesia.
Based on this study the investigators intend to verify the role and potential mechanism of S-ketamine combined anesthesia in alleviating hyperalgesia after cesarean section, prove that it can reduce hyperalgesia and postoperative pain. explore the role of S-ketamine in alleviating postoperative hyperalgesia in different PCA ways and explore the safety of S-ketamine in the perilactation

Outcome Measures
Primary Outcome Measures
- Hyperalgesia at 30 after surgery [Change from baseline to 30 minutes postoperatively]
Pain threshold and pain tolerance in the forearm of dominant hand
- Hyperalgesia at 24 hours after surgery [Change from baseline to 24 hours postoperatively]
Pain threshold and pain tolerance in the forearm of dominant hand
Secondary Outcome Measures
- Pain score (NRS socre) at 0-6 hours postoperatively [From ending of the surgery to 6 hours postoperatively]
NRS score: Pain was assessed on a scale of 0-10, with 0 being no pain and 10 being most painful
- Pain score (NRS socre) at 6-12 hours postoperatively [From 6 hours postoperatively to 12 hours postoperatively]
NRS score: Pain was assessed on a scale of 0-10, with 0 being no pain and 10 being most painful
- Pain score (NRS socre) at 12-24 hours postoperatively [From 12 hours postoperatively to 24 hours postoperatively]
NRS score: Pain was assessed on a scale of 0-10, with 0 being no pain and 10 being most painful
- The number of patient controlled analgesia pump pressed [0-48 hours postoperatively]
When the patients felt pain, the patient controlled analgesia pump can be pressed once
- Patient controlled analgesia pump analgesic consumption [0-48 hours postoperatively]
The amount of the analgesic consumption
