The Role of Preoperative and Postoperative Transversus Abdominis Plane and Rectus Sheath Block in Patients Undergoing Total Laparoscopic Hysterectomy

Purpose: This study was performed to assess the efficacy of a preoperative and postoperative transversus abdominis plane (TAP) and rectus sheath (RS) block compared with no TAP and RS block in patients undergoing total laparoscopic hysterectomy (TLH).

Design: Prospective observational cohort study.

Methods: From January 2014 to December 2017, 195 women undergoing TLH were categorized into three groups based on their perioperative analgesia: no TAP + RS block (n = 88), preoperative TAP + RS block + systemic analgesia (n = 68), and postoperative TAP + RS block + systemic analgesia (n = 39). We evaluated use of nonsteroidal anti-inflammatory drugs (NSAIDs) and NSAID consumption within the first 12 hours postoperatively and the numerical rating scale score at 0, 12, and 24 hours postoperatively.

Findings: Women with a preoperative TAP + RS block had a significantly lower utilization rate of NSAIDs within the first 12 hours postoperatively (54.4% vs 75.0%; P = .007), lower postoperative flurbiprofen dose (45.5 vs 62.0 mg; P = .048), and lower numerical rating scale score at 12 hours postoperatively (1.63 vs 2.20; P = .002) compared with women with no TAP + RS block.

Conclusions: A preoperative TAP + RS block provided superior postoperative analgesia in patients undergoing TLH and reduced analgesic consumption during the first 12 hours postoperatively.
