Not Applicable
Completed
Conditions
Gynecological; Surgery (Previous), Affecting Fetus or Newborn, Due to Obstructed Labor
Analgesia
Interventions
Drug: 0.25mg/kg of esketamine in combination with 2 mg morphine sulfate
Drug: 0.25mg/kg of esketamine in combination with 1 mg morphine sulfate
Drug: 2 mg morphine sulfate
Registration Number
NCT05582135

Brief Summary

The aim of this study was to determine whether the addition of esketamine to morphine would improve postoperative analgesia after caesarean section.

Parturients who planned for a caesarean delivery using combined spinal-epidural anaesthesia with a request for postoperative anaesthesia were randomly divided into four groups (A, B, C and D). When the surgery was completed, the parturients in groups A, B, C and D were administered 2 mg morphine, 0.25mg/kg of esketamine, 0.25mg/kg of esketamine plus 2 mg morphine sulfate and 0.25mg/kg of esketamine plus 1 mg morphine through the epidural catheters, respectively. The postoperative pain at rest, pain with movement, the number of rescue analgesics and adverse effects were evaluated for 48 h after caesarean delivery.

Primary Outcome Measures
NameTimeMethod
Postoperative pain score at restForty-eight hours after caesarean delivery

The pain scores at rest were evaluated by the parturients themselves using a VAS based on a linear scale from 0 to 10, where 0 represented an absence of pain and 10 represented maximal pain.

Postoperative pain score with movementForty-eight hours after caesarean delivery

The pain scores on movement were evaluated by the parturients themselves using a VAS based on a linear scale from 0 to 10, where 0 represented an absence of pain and 10 represented maximal pain.
