Randomized Controlled Trial Clinical TrialLack of postoperative pain relief after hysterectomy using preperitoneally administered bupivacaine.
It is well known that wound infiltration with local anesthetic can reduce postoperative pain in various degrees and with very few side effects. A previous study showed better analgesic effect when local anesthetic was applied in the subfascial, rather than the subcutaneous, layer. The present study investigated the effect of frequent bolus injections of bupivacaine (15 mL 2.5 mg/mL) preperitoneally through catheters placed intraoperatively in women who had undergone hysterectomy. ⋯ Bolus injections of bupivacaine through intraoperative placed catheters did not improve analgesia postoperatively compared with saline injections.
