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

Arms and Interventions

Arm Intervention/Treatment
Experimental: E1

S-ketamine was administered intravenously after delivery,patient controlled epidural analgesia(PCEA)was administered postoperatively PCEA formula:(10μg/ml hydromorphone+0.11% ropivacaine) 200ml

Drug: S-ketamine
S-ketamine or placebo were given to the fetus after delivery Patient-controlled intravenous analgesia or patient-controlled epidural analgesia were administered postoperatively
Other Names:
  • Patient controlled analgesia
  • Experimental: E2

    S-ketamine was administered intravenously after delivery,patient controlled intravenous analgesia(PCIA) was administered postoperatively PCIA formula:(100μg/ml hydromorphone) 100ml

    Drug: S-ketamine
    S-ketamine or placebo were given to the fetus after delivery Patient-controlled intravenous analgesia or patient-controlled epidural analgesia were administered postoperatively
    Other Names:
  • Patient controlled analgesia
  • Placebo Comparator: C1

    placebo was administered intravenously after delivery,patient controlled epidural analgesia(PCEA) was administered postoperatively PCEA formula:(10μg/ml hydromorphone+0.11% ropivacaine) 200ml

    Drug: S-ketamine
    S-ketamine or placebo were given to the fetus after delivery Patient-controlled intravenous analgesia or patient-controlled epidural analgesia were administered postoperatively
    Other Names:
  • Patient controlled analgesia
  • Placebo Comparator: C2

    placebo was administered intravenously after delivery,patient controlled intravenous analgesia(PCIA) was administered postoperatively PCIA formula:(100μg/ml hydromorphone) 100ml

    Drug: S-ketamine
    S-ketamine or placebo were given to the fetus after delivery Patient-controlled intravenous analgesia or patient-controlled epidural analgesia were administered postoperatively
    Other Names:
  • Patient controlled analgesia
  • Outcome Measures

    Primary Outcome Measures

    1. Hyperalgesia at 30 after surgery [Change from baseline to 30 minutes postoperatively]

      Pain threshold and pain tolerance in the forearm of dominant hand

    2. 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

    1. 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

    2. 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

    3. 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

    4. 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

    5. Patient controlled analgesia pump analgesic consumption [0-48 hours postoperatively]

      The amount of the analgesic consumption
