Postoperative SpO₂/FiO₂ Ratio and Analgesic Methods in Laparoscopic Surgery
Sponsor: Istinye University
Summary
This prospective observational study aims to evaluate the association between postoperative oxygenation, assessed by the SpO₂/FiO₂ ratio, and body mass index (BMI), STOP-BANG score, and postoperative analgesic methods in patients undergoing elective laparoscopic cholecystectomy in the reverse Trendelenburg position. Postoperative SpO₂ and FiO₂ values will be recorded within the first postoperative hour, and the SpO₂/FiO₂ ratio will be calculated. Analgesic techniques applied as part of routine clinical practice will be documented. The study does not involve any additional intervention beyond standard care. The findings are expected to contribute to a better understanding of factors associated with early postoperative oxygenation and hypoxemia risk.

Standard of Care
No intervention is applied in this study. Patients are managed according to routine clinical practice. Demographic data, body mass index, STOP-BANG score, postoperative analgesic methods, and postoperative SpO₂ and FiO₂ values are recorded, and the SpO₂/FiO₂ ratio is calculated.
