Summary

This randomized clinical study aims to compare the postoperative analgesic efficacy, analgesic consumption, and patient satisfaction of erector spinae plane (ESP) block administered in three different patient positions-lateral, prone, and sitting-in individuals undergoing elective laparoscopic cholecystectomy. The study also evaluates the variation in skin-to-block site distance depending on patient positioning.

Detailed description

Erector spinae plane (ESP) block is a relatively recent regional anesthesia technique performed under ultrasound guidance, widely used for managing acute postoperative pain. While the ESP block is known for its safety, simplicity, and versatility, there is limited evidence regarding the influence of patient positioning on its clinical effectiveness and technical performance. This prospective, randomized, single-blind study investigates the impact of administering bilateral ESP block at the T7 vertebral level in three different patient positions: lateral decubitus, prone, and sitting. The study includes adult patients (aged 18-65, ASA I-II) undergoing elective laparoscopic cholecystectomy under general anesthesia. Primary outcomes include postoperative pain scores (VAS and NRS). Secondary outcomes include total rescue analgesic consumption (tramadol), time to first analgesic requirement, patient satisfaction scores (Likert scale), and measurement of the skin-to-block site distance across different positions. Data will be collected at defined intervals up to 24 hours postoperatively. The findings are expected to inform clinicians on the optimal patient positioning for ESP block to enhance block efficacy and patient comfort during laparoscopic abdominal surgery.
