Comparison of Endotracheal Intracuff Pressure Between Two Cuff Sealing Methods

Not Applicable

Completed

• Conditions: Endotracheal Tube

• Registration Number: NCT03385044
• Lead Sponsor: DongGuk University

Brief Summary

The endotracheal intracuff pressure is to be maintained at a low level to prevent trachea and nerve damages, and yet be high enough to secure air sealing. The objective of the study is to compare minimal occlusive volume technique (MOVT) and expired volume/inspired volume ratio (VE/VI ratio) from a spirometer method of endotracheal tube (ETT) cuff inflation with respect to the cuff pressure required to seal the airway during a laparoscopic surgery under general anesthesia. A study design is a randomized crossover trial in 35 patients. The primary outcome is the intracuff pressure of an endotracheal tube. The study consists of two cuff sealing methods separated by a period of 10 minutes.
