Effect of Applying Cuff Air Leak Pressure as Intraoperative Cuff Pressure on Postoperative Complications

Not Applicable

Withdrawn

• Conditions: Intubation Complication

• Registration Number: NCT04302142
• Lead Sponsor: The University of Texas Health Science Center, Houston

Brief Summary

The purpose of the study is to achieve effective ventilation with critical intracuff pressure (Pcr) and determine if application of Pcr reduces the risks associated with over-insufflation of endotracheal cuff including postoperative sore throat, cough,nausea, vomiting, aspiration, and pneumonia.
