Abstract

Introduction

The use of the videolaryngoscope (VL) facilitates intubation in adults and children, but experience in neonates is scarce. The objective of this study was to compare the VL with the classic laryngoscope (CL) in acquiring the skill of neonatal endotracheal intubation (ETI) and evaluate transferability of skill from VL to CL. We hypothesize that, on a neonatal mannequin, the VL will be superior to the CL with regard to success rate and that the skill will be transferred from VL to CL.

Methods

A randomized controlled trial was held at Sainte-Justine Hospital’s simulation center. Third- and fourth-year medical students were randomized into group A, which used VL for the first phase and CL for the second phase, and group B, which used CL for both phases. Each subject performed 9 ETI on 3 simulated neonatal airways in each phase.

Results

Thirty-four students performed 612 intubations. Success in group A was higher than in group B in the first phase of the study (96.5% vs. 84.6%, P < 0.001). During phase 2, group A’s success did not change significantly (91.7% vs. 96.5%, P = 0.07). Time to successful intubation was longer using the VL (27.6 vs. 15.6 seconds, P < 0.001), but there was no difference in phase 2 (12.5 vs. 10.2 seconds, P = 0.24). There were no esophageal intubations using the VL.

Conclusions

Success rate of ETI on mannequins was improved, and esophageal intubations decreased while learning ETI using the VL compared with the CL. Once ETI is learned on mannequins using the VL, this skill is transferrable to the CL.
