Postoperative SpO₂/FiO₂ in Obese and Non-Obese Patients: Role of STOP-BANG

Not yet recruiting

• Conditions: Oxygen Deficiency

• Registration Number: NCT07188649
• Lead Sponsor: Istinye University

Brief Summary

The aim of this study is to evaluate the effect of the Reverse Trendelenburg position on oxygenation (SpO₂/FiO₂ ratio) in the early postoperative period in patients undergoing laparoscopic surgery. In our study, obesity is considered as a comparative subgroup in terms of variability of this effect; additionally, the STOP-BANG score, which measures the risk of obstructive sleep apnea syndrome, is examined as an auxiliary indicator.
