OBJECTIVE:Gynaecological oncological surgery (GOS) includes a wide variety of surgical procedures and postoperative pain is a major concern. This study compared the impact of intrathecal morphine (ITM) plus patient-controlled analgesia (PCA) with PCA alone on morphine consumption, pain relief and patient satisfaction after GOS. METHODS:Sixty women undergoing GOS under general anaesthesia were randomized to receive either 0.3 mg ITM or placebo. On arrival at the postanaesthesia care unit each patient received a morphine PCA pump. The three primary outcome measures were pain, patient satisfaction scores evaluated using a 100-mm visual analogue scale and cumulative PCA morphine consumption. RESULTS: No significant differences were observed in the demographic data. Cumulative PCA morphine consumption was significantly lower in the ITM group compared with the control group. Fatigue scores were lower in the ITM group compared with the control group but did not reach statistical significance. Pain, sedation and patient satisfaction scores, and the rate of side-effects were similar for the two groups. CONCLUSIONS: Administering ITM in GOS could improve postoperative analgesia and reduce morphine consumption without serious side-effects.
