Summary

Multimodal opioid-sparing analgesia is recommended in order to prevent post-operative complications and shorten length of stay. Administration by the surgeon of local anesthetics in the abdominal wall after surgery for a suspected gynaecological malignancy will be studied. Eighty women above the age of 18 and undergoing a midline laparotomy for a suspected gynecologic malignancy will be recruited. Half of these women will received a Transversus Abdominis Plane (TAP) block using local anesthetics, and half will receive a placebo (saline water). The primary outcome studied will be the total dose of opioid in morphine equivalents received in the postoperative period. The primary hypothesis is that surgeon-performed TAP blocks reduce the need for opioids after surgery. Secondary outcomes including postoperative pain scores, postoperative nausea and vomiting rates, time to flatus, incidence of clinical ileus and time to discharge from hospital will also be recorded.

Interventions

PROCEDURE

Surgeon-administered transversus abdominis plane (TAP)

Prior to fascial closure, the rectus muscle is gently elevated superiorly and the surgeon identifies its lateral border; the nerves that supply the anterior abdominal wall travel through the myofascial plane between internal oblique and transversus abdominis muscles, 2 fingerbreadths above the iliac crest. Access to this plane can easily be achieved by inserting a blunted needle through the parietal peritoneum; there is an appreciable loss of resistance ('one pop') and the correct plane is entered. After careful aspiration to ensure no vascular injury has occurred, 20 mL 0.25% bupivacaine or 20 mL of normal saline is injected slowly. The same procedure is repeated on the other side.
