Impact of Cricoid Pressure and BURP on Airway Dimensions
This study aims to observe how cricoid pressure and the BURP maneuver affect the dimensions of your airway.
Data Collection
Summary
Study start date: June 1, 2011
Actual date on which the first participant was enrolled.Cricoid pressure (CP) and the backward-upward-rightward pressure (BURP) manoeuver, are extralaryngeal manoeuvers which are widely applied during endotracheal intubation, respectively offering potential protection against passive gastric regurgitation and improved laryngeal view in emergency airway management. Their validity in achieving an improvement of the laryngeal view has been questioned. The objective of this study is to measure the change in mean anterior-posterior rima glottidis (APRIMA) distance and mean area under the vocal cords after backward upward rightward pressure (BURP) and cricoid pressure (CP). The investigators will measure the APRIMA distances and areas under the vocal cords, using a specially created module in the program DeVIDE. The measurements assessed during BURP and CP will be expressed relative to the measurements when no external pressure is applied.
