Evaluation of Techniques for Tracheal Tube Exchange in Standard and Critical Care Patients

Study Overview
=================
Brief Summary
-----------------
A randomized controlled study to evaluate different Techniques and Approachs for the Exchange of a tracheal tube or supraglottic airway device in a Simulator

Detailed Description
-----------------
Exchanging a tracheal tube (ETT) in the high-risk difficult airway patient carries the risk of hypoxemia and the potential of a lost airway. Maintaining continuous airway access during the exchange by incorporating an airway exchange catheter (AEC) or similar device may reliably lessen exchange risk, especially in the known or suspected difficult airway patient, by providing a conduit to facilitate ETT passage into the trachea. We evaluated some approven / etablished techniques in a Simulator based study design.
