Airway Manoeuvers - Implications for Airway Management?

In anesthesia, intubation is a technique used to secure an airway. This technique is not always straightforward. Sometimes it is difficult to place an endotracheal tube. There are two manners of giving pressure to the patients neck, to improve view and facilitate intubation.

The investigators hypothesize that by giving this pressure the effective work area is likely to be smaller. The investigators would like to quantify this effect by measuring the effective work area, using a specially designed computer program.

About this study

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.
