The effects of laparoscopic guided transversus abdominis plane (TAP) block in sleeve gastrectomy procedure: a randomized single blinded placebo controlled trial

Abstract

Aims: Laparoscopy-guided transversus abdominis plane (TAP) block is a novel postoperative analgesic modality. We aimed to explore the effect of TAP block in laparoscopic sleeve gastrectomy (LSG) procedures. Methods: Forty patients were randomized into two groups: TAP block with bupivacaine and placebo. Visual analog scale scores at postoperative hours 1, 6, 12, and 24, total analgesic consumption and opioid doses, and postoperative nausea and vomiting (PONV) scores were evaluated between the groups. Results: Postoperative first-hour VAS scores differed significantly between the groups (p
