BACKGROUND AND AIMS

Parenteral analgesics and epidural analgesia are two standard options to treat postoperative pain after total abdominal hysterectomy (TAH). Fascial plane blocks such as transversus abdominis plane (TAP) block have gained popularity recently. However, effect of these analgesic regimens on quality of postoperative recovery (QoR) has not been studied. Hence we aimed to assess and compare the QoR with three different postoperative analgesic regimens---parenteral analgesia, epidural analgesia, and TAP block in patients undergoing TAH under general anesthesia.

MATERIAL AND METHODS

Sixty female patients undergoing TAH were randomized into three groups of 20 each for postoperative analgesia. Epidural group received boluses of 0.125% bupivacaine for 24 h, parenteral group received injection diclofenac and injection tramadol alternately every 6 h for 24 h, and TAP group received bilateral TAP block with 0.25% bupivacaine at end of operation. QoR was assessed postoperatively by 40-item questionnaire-QOR-40 and pain was assessed by numerical rating scale (NRS).

RESULTS

QOR-40 score was comparable across the three groups at 24, 48, and 72 h postoperatively. TAP block prolonged the time to first rescue analgesic ( = 0.02) and reduced the total 24-h postoperative morphine consumption by 2.4 (95% CI: 1.0, 3.8) mg ( = 0.002) and 7.8 (95% CI: 6.4, 9.1) mg ( < 0.001) when compared with epidural and parenteral groups, respectively.

CONCLUSION

The QoR after abdominal hysterectomy is similar with either intravenous analgesics or epidural analgesia or TAP block when used with rescue analgesia to manage postoperative pain. TAP block provides superior analgesia and reduces 24-h morphine consumption when compared with parenteral and epidural analgesia.
