Voice Tessitura and Size of the Required Laryngeal Mask — EVG  

Laryngeal Masks Clinical Trial

Official title:
Voice Tessitura and Size of the Required Laryngeal Mask

Clinical Trial Summary

The choice of the size of the laryngeal mask (i-gel) is based on the weight. Even following the weight recommendations, it is quite common to choose a mask that is too big or too small, which leads to ventilation leaks (too small), or insertion failures (too big) and leads to a change of mask for bigger or smaller.

The i-gel are laryngeal masks (2nd generation) which consist of gel and have been designed by molding on larynx corpses. The masks are not inflatable (so not adaptable).

I-gel masks are used in adult and pediatric patients for weights ranging from 2 Kg to over 90 Kg to provide ventilation during general anesthesia.

Patients with a deep voice probably need a larger laryngeal mask than their weight alone suggests.

The investigators propose to measure the lowest sound emitted by the patient because it would seem logical that the larger the larynx is, the more the voice is serious.

This hypothesis will be verified a posteriori by the size of the laryngeal mask used and adapted by comparing it to the range of the voice.
