Benchmarking the Applicability of Four Methods of Endotracheal Tube Cuff Inflation for Optimal Sealing: A Randomized Trial.

Purpose: To assess the comparable applicability of four methods of endotracheal tube cuff (ETTc) inflation on the basis of optimal level of intracuff pressure and presence of intubation-related complications.

Design: Double-blind, randomized trial.

Methods: A total of 139 adult surgical patients scheduled to undergo nitrous oxide-free general anesthesia were assigned into one of four groups according to the method used for ETTc inflation.
