LUNG ULTRASOUND GUIDED POSITIVE END EXPIRATORY PRESSURE ADJUSTMENT IN ENHANCED RECOVERY PROGRAM BASED LAPAROSCOPIC BARIATRIC SURGERY

Abstract

Objective: This prospective study aims to evaluate the effectiveness of lung ultrasound-guided positive end-expiratory pressure (PEEP) adjustment in optimizing respiratory mechanics and enhancing recovery in patients undergoing laparoscopic bariatric surgery within an enhanced recovery program (ERP).

Methods: Patients scheduled for laparoscopic bariatric surgery within an ERP were enrolled. Lung ultrasound was performed preoperatively and intraoperatively to assess lung recruitment and optimize PEEP levels. Respiratory parameters, including oxygenation indices and ventilatory mechanics, were monitored throughout the perioperative period. Postoperative outcomes, including pulmonary complications, and overall recovery, were assessed.

Results: Preliminary results indicate that lung ultrasound-guided PEEP adjustment effectively optimized lung recruitment and improved respiratory mechanics during laparoscopic bariatric surgery within an ERP. Patients in the intervention group demonstrated better oxygenation indices and more stable ventilatory parameters compared to controls (p-value <0.05). Additionally, the intervention group showed reduced rates of postoperative pulmonary complications indicating enhanced recovery.

Conclusion: Lung ultrasound-guided PEEP adjustment represents a promising approach for optimizing respiratory function and enhancing recovery in patients undergoing laparoscopic bariatric surgery within an ERP. Further studies are warranted to validate these findings and establish standardized protocols for its implementation in clinical practice.
