Comparison of the Effect of Supine and Prone Position on the Ultrasonographic Airway Measurements

Not Applicable

Completed

• Conditions: Respiratory Complication; Airway Edema; Obstructive Sleep Apnea
• Interventions: Diagnostic Test: preoperative airway ultrasonography; Diagnostic Test: postoperative airway ultrasonography

• Registration Number: NCT05197400
• Lead Sponsor: Ankara City Hospital Bilkent

Brief Summary

The aim of this study is to compare the preoperative and postoperative ultrasonographic measurements of patients undergoing in the prone position and the change in upper airway edema.

The secondary aim of the study is to investigate the relationship between OSAS risk levels determined by the STOP-BANG score in the preoperative period of the patients participating in the study, and airway ultrasound measurements and postoperative critical respiratory events in the preoperative and postoperative period.
