Tracheal intubation using a videolaryngoscope (Glidescope®) on a mannequin

Abstract

Our work consists to evaluate the learning of GlideScope® by nurse anesthetists of CHUSS.

Prospective single-center study has been conducted in CHUSS. 30 operators with varying experience in anesthesia have made each 10 attempts of orotracheal intubation with GlideScope® on a mannequin of standard adult intubation. The primary endpoint was the time required to perform tracheal intubation. The secondary endpoints included: the length of exposure, the time between exposure and the glottal intubation and the rate of intubation failure.

There was a significant decrease in the duration of intubation between the first and last test, indicating learning by different operators. However, this decrease is not continuous, and there is a plate from the sixth test. The overall failure rate across all attempts was 7.7%. We did not find a failure from the third attempt. All failures occurred after exposure and were 2 types: esophageal intubation, or the insertion of the tube failure in the time (120 seconds). It is not noted impact of the experience on the learning speed.

The GlideScope® need learning. This learning is fast and the high rate of success that provides whatever the previous experience of the operator can advocate the use of GlideScope® in our context or most intubations are made by nurse anesthetists.
