Summary
Laparoscopic cholecystectomy and the associated pneumoperitoneum can impair diaphragmatic mechanics and reduce postoperative oxygenation. This prospective observational study aims to evaluate perioperative changes in diaphragmatic excursion measured by ultrasonography and to investigate their association with early postoperative oxygenation parameters and hypoxemia. By correlating diaphragmatic excursion changes with SpO₂/FiO₂ and the ROX index, the study seeks to clarify the physiological contribution of diaphragmatic dysfunction to postoperative hypoxemia in patients undergoing laparoscopic cholecystectomy.
