Diaphragmatic Excursion Changes and Postoperative Oxygenation After Laparoscopic Cholecystectomy
Sponsor: Istinye University
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.

Conditions
Interventions
Standard perioperative care with observational diaphragm ultrasonography
No therapeutic intervention is applied in this study. All patients receive standard perioperative anesthesia and surgical care according to institutional routine. Diaphragmatic excursion is assessed non-invasively using ultrasonography in the preoperative period and at 15 minutes postoperatively in the post-anesthesia care unit. Oxygenation parameters and respiratory variables are recorded for observational analysis only.
