BACKGROUND: Local analgesia through wound catheters is used as a part of multimodal analgesia. The efficacy of continuous subfascial wound infusion compared to epidural analgesia is unknown for abdominal hysterectomy and bilateral salpingo-oophorectomy (TAH-BSO) via Pfannenstiel incision. The aim of this study was to compare the aforementioned two methods in this type of surgery for postoperative morphine consumption, acute and persistent postsurgical pain.
METHODS: Fifty patients enrolled in the study were randomly allocated to receive continuous 10 mL/h levobupivacaine either via subfascial (Group S) or epidural (Group E) catheter for 48 h postoperatively. In Group S 0.25% levobupivacaine was used for the first six hours and 0.125% thereafter, whereas Group E received 0.125% levobupivacaine throughout the study period. Cumulative morphine consumption, static and dynamic pain, gastrointestinal recovery, ambulation, patient satisfaction, hospital stay, as well as pain at 2nd and 6th months were evaluated.
RESULTS: Group S was superior to Group E regarding cumulative morphine consumption (16.8±7.2 mg and 28.7±10.3 mg respectively, P<0.001; mean difference -11.9 with 95% CI of the difference -17.1 to -6.7) and pain relief. Patient satisfaction was higher in Group S compared to Group E (P=0.006). Less postoperative vomiting was observed in Group S. No difference was detected in length of hospital stay and persistent postsurgical pain incidence.
CONCLUSION: Wound analgesia via subfascial catheter with continuous levobupivacaine infusion decreases postoperative morphine consumption and increases patient satisfaction compared to epidural analgesia with no difference in persistent postsurgical pain following TAH-BSO via Pfannenstiel incision.
