Item Erector spinae plane block versus transversus abdominis plane block in laparoscopic hysterectomy(Future Science Group, 2022-11) Warner, Matthew; Yeap, Yar Luan; Rigueiro , Gabriel; Zhang , Pengyue; Kasper , Kelly; Obstetrics and Gynecology, School of MedicineBackground: The objective was to determine whether an erector spinae plane (ESP) block could provide additional postoperative analgesic benefits compared with a transversus abdominis plane block. Methods: 78 patients were separated into two groups (n = 39 per group). Both groups received bilateral injections of 266 mg Exparel® (20 ml) and 60 ml of 0.125% bupivacaine. Patients undergoing a transversus abdominis plane block received these injections intraoperatively, while patients undergoing an ESP block received these preoperatively. Outcomes were measured based on scores in opioid usage; pain (visual analog scale) at rest and with movement; nausea; sedation and patient satisfaction. Results: There were no significant intergroup differences in any category (all scores had p > 0.05). Conclusion: No additional analgesic benefits were found using the ESP block procedure.Item Erector Spinae Plane Blocks vs No Blocks for Laparoscopic Hysterectomy(2022-09-17) Blais, Austin; Yeap, Yar; Warner, MatthewBackground: Erector spinae plane blocks have recently gained traction in modern literature as a simple and effective alternative to Transverse Abdominis Plane (TAP) blocks for decreasing post-operative abdominal pain. Post-operative pain causes a significant burden to patients receiving laparoscopic hysterectomy, which can be ameliorated with effective anesthetic care promoting faster recovery. Objective: Our study aims to test the hypothesis that ESP block patients will have better pain scores and less opioid usage compared to patients who only receive IV pain meds. Methods: We performed a retrospective chart review on patients at University Hospital who underwent laparoscopic hysterectomy between May 2019-August 2021. 64 patients met criteria for inclusion. Those who received ESP block were compared with controls who received no block. Results: Our review found a significant reduction in both the patient reported max pain (4.0 vs 7.0, P=0.005) and average pain scores (2.2 vs 3.5, P=0.029) as measured by the Visual Analogue Scale. Conclusion: The erector spinae plane block shows potential for being an effective and simple alternative to TAP blocks or to IV opioids for the control of post-operative pain in laparoscopic hysterectomy.
