Abstract


Background: Gynaecological surgeries are performed by abdominal incision is common and post-operative pain and discomfort is always anticipated. TAP block is a regional anaesthetic technique which blocks the abdominal neural afferents by administrating local anaesthetic drugs into the neuro-fascial plane. The other method for postoperative analgesia is surgical wound infiltration with local anaesthetic drugs. The aim of this study was to evaluate the post-operative analgesic efficacy of TAP block versus wound infiltration in gynaecological surgeries.

Methods: The study was a prospective randomized study conducted on patients undergoing open gynaecological surgeries, conducted at the Government medical college and ESI hospital, Coimbatore. The study was initiated after obtaining an ethical clearance from the institution. Group A: patients who underwent bilateral TAP block with 0.3 ml/kg 0.25% Bupivacaine on each side. Group B: patients who received wound infiltration of 0.25% Bupivacaine 0.6ml/kg.

Results: TAP block provided superior analgesic effect than the surgical site infiltration group, without significant changes in the hemodynamic parameters. The duration of analgesia was longer and the need of Tramadol in the postoperative period was found to be lesser in the TAP block group as compared to wound infiltration group.

Conclusions: The TAP block is an effective and safe technique for postoperative analgesia for gynaecological surgeries than compared to the surgical wound infiltration. The requirement of Tramadol as a postoperative analgesia was less with TAP block compared to surgical wound infiltration.
