Success of Pediatric Anesthesiologists in Learning to Use Videolaryngoscopes

University of Alberta646 enrolled

Overview

There are two new instruments on the market that anesthesiologists use when putting a breathing tube into the lungs of patients. The purpose of this study is to see how easily anesthesiologists can learn to use them in children.

Each anesthesiologist performed 20 timed baseline intubations. They were then randomized to perform 20 timed intubations with one of the two new videolaryngoscopes followed by 20 with the other new videolaryngoscope. The goal was to see how quickly they could become proficient.

Outcomes

Primary Outcomes

Success in Learning to Use a Videolaryngoscope(VLS)

Anesthesiologists were to perform 20 intubations with each videolaryngoscopes. #1-10 were for practice. "Rapid Success" was no failed intubation attempts on #11-20 and a median time-to-intubation no more than 50% longer than their baseline median time-to-intubation on #11-15 . "Delayed Success" was achieving these same parameters on #16-20 if they were not achieved on #11-15. Operators who did not achieve either goal were labeled as having "No Success".

Time frame: Up to 5 minutes per intubation

Secondary Outcomes

Cormack & Lehane Score

This Outcome was designed to determine if the view of the airway as determined by the Cormack \& Lehane grading system is improved by use of the GlideScope (GS) video laryngoscope and/or the Karl Storz Direct Coupled Interface (DCI) (KS) video laryngoscope as this would be a surrogate marker for utility in a difficult airway. Score is reported as a whole number from I to IV with I being an easy intubation and IV being one where the larynx cannot be visualized at all.

Time frame: reported during intubation (up to 5 minutes)

Time to Intubation, Analyzed by Order of Laryngoscopes Used

To determine if the learning curve was altered by the order in which the two new laryngoscopes were learned by the anesthesiologist,mean and median times on intubations #16-20 were compared for the two videolaryngoscopes.

Time frame: 4 years

Time to Intubation, Stratified by Weight of Patients

To compare the time-to-intubation for these laryngoscopes in children of different weights.

Time frame: 4 years

Mean Years Since Completion of Anesthesiology Residency

To investigate whether there was a correlation between the years since completion of anesthesiology residency to the mid-point of study (2008)and median time-to-intubation for all first attempt intubations for the study. Years since completion of anesthesiology residency reported in the data table, correlation reported in the statistical analysis below
