İn This Study, Patients Undergoing Bariatric Surgery Will be Divided Into Two Groups. The Control Group Will Receive Normal-flow, While the Study Group Will Receive Low-flow Inhalational Anesthesia. The Aim is to Compare the Incidence of Postop Atelectasis-between the Two Groups Using USG Evaluation

• Conditions: Ultrasonography; Atelectasis; Pulmonary Complications

• Registration Number: NCT07041567
• Lead Sponsor: Istanbul University

Brief Summary

This study is a clinical trial and its purpose is to evaluate the effect of low and normal flow anesthesia on atelectasis formation in patients undergoing bariatric surgery by ultrasonography.

In this study, lung ultrasounds and respiratory function tests will be performed on volunteers before and after surgery. These procedures are completely painless and safe.

No invasive procedure will be performed in the study; the methods used do not pose any additional risk other than existing treatment procedures.
