Erector spinae plane block versus transversus abdominis plane block in laparoscopic hysterectomy. Pain Management, 12(8), 907–916. https://doi.org/10.2217/pmt-2022-0037https://hdl.handle.net/1805/40892Background: 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.en-USAttribution-NonCommercial-NoDerivatives 4.0 InternationalESP blockTAP blockanalgesialaparoscopic hysterectomypain managementpostoperative painArticle
