Post-operative Sore Throat as Determined by Endotracheal Tube Inflation Technique

This study has been completed.

University of California, San Francisco Identifier:
First received: February 24, 2011
Last updated: January 6, 2014
Last verified: January 2014

The purpose of this study is to test whether the incidence of sore throat and other tracheal co-morbidities such as dysphagia and hoarseness can be lessened by use of a cuff manometer at the beginning of surgery to inflate to the proper pressure compared to the standard technique.

The investigators hypothesis is that inflation of the endotracheal balloon using a cuff manometer immediately after intubation will reduce the incidence of sore throat and other tracheal co-morbidities.
