Erector Spinae Plane Block and its Impact on Postoperative Diaphragmatic Dysfunction in Morbidly Obese Patients Undergoing Laparoscopic Sleeve Gastrectomy: A Double-Blind Randomized Control Trial

Bilateral ESP block in individuals with class III obesity undergoing sleeve gastrectomy significantly reduces the incidence of postoperative diaphragmatic dysfunction, preserves pulmonary function, and reduces postoperative nalbuphine consumption. These findings support the integration of erector spinae plane blocks into multimodal perioperative strategies to enhance respiratory outcomes and patient comfort in patients living with obesity undergoing metabolic bariatric surgery.
