Brief summary
The goal of this clinical trial is to learn the clinical and cost effectiveness of intrathecal morphine (ITM) in addition to usual care as a postoperative pain relief strategy following major laparoscopic abdominal surgery compared with current usual care. The main questions it aims to answer are: An enhanced analgesic technique, consisting of ITM in addition to usual care , improves the postoperative quality of recovery at day 1 after surgery by at least 6 points on the 15-item quality of recovery questionnaire (QoR-15) compared to usual care alone, in patients undergoing major laparoscopic abdominal surgery? Researchers will compare ITM + Usual care to Sham ITM + Usual Care (The sham ITM mimics the ITM procedure, but the dura is not breached) to see if ITM works to postoperative pain relief. Participants will: Receive ITM + Usual care or Sham ITM + Usual care on surgery day Have interview with outcome assessors and complete the CRFs on the day of surgery, postoperative day 1, day 2, day 3 and up to postoperative day 30
Interventions
The participants allocated to this group will receive ITM (Intrathecal Morphine) in addition to usual care with opioid-based PCA(Patient-Controlled Analgesia). ITM consists of an intrathecal injection of 300 micrograms (0.3mg) of preservative-free morphine.Usual care involves postoperative analgesia with opioid-based PCA without postoperative continuous infusion of opioids. No other drugs other than opioids are allowed in the PCA.
The sham ITM mimics the ITM procedure, but the dura is not breached.
