Summary

A study of a new approach to determining if, following endotracheal intubation, the endotracheal tube (ETT) is in the trachea or the esophagus. The test for correct placement consists of inflating the cuff to a pressure of 50 (to be determined by the study) and tugging the ETT gently up and out of the mouth. The investigators hypothesize that if it is in the esophagus, it will slide easily all the way out; if in the trachea, the cuff will be impeded by catching on the lower surface of the cricoid ring, and that this will require a greater force to extubate with cuff inflated than that required for the esophagus.

Conditions

  • Intubation, Intratracheal

Interventions

DIAGNOSTIC_TEST

Measuring extubation force

Intubation of the esophagus of anesthetized participants who are having planned endotracheal intubate for surgery; inflation of the cuff; attachment of a force transducer to the tube connector; and gently tugging the tube out of the mouth. Then intubating the esophagus and repeating the tugging procedure. Meanwhile, the force of resistance to tugging is measured with a force transducer.
