Teach Intubation by Novices in Anaesthesiology

Study Overview
=================
Brief Summary
-----------------
Comparision of direct laryngoscopy and video laryngoscopy to learn successful tracheal intubation by novices in anaesthesiology

Detailed Description
-----------------
Video laryngoscopy has been recommended as an alternative during difficult conventional direct laryngoscopy using the Macintosh blade. However, successful visualisation of the larynx and tracheal intubation using some of the indirect laryngoscopes or video laryngoscopy requires hand-eye coordination. To best of our knowledge in the current literature there are no data how is the best educative way to learn successful tracheal intubation by novices in anaesthesiology.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Crossover Assignment
Interventional Model Description: Starting with 100 tracheal intubations with conventional tracheal intubation and videolaryngoscopy and after 100 intubations change the device for the next 100 intubations
Masking: Single


Arms and Interventions

| --- | --- |
| Experimental: Videolaryngoscopy (McGrath Macintosh)<br>First pass success rate using the videolaryngoscopy | Device: Videolarygoscopy<br>* In a randomised order we evaluate the first pass success rate of the tracheal tube into the trachea.<br>|
| Experimental: conventional direct laryngoscopy<br>First pass success rate using the conventional direct laryngoscopy | Device: conventional laryngoscopy<br>* In a randomized order we evaluate the first pass success rate of the tracheal tube into the trachea.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| First pass success rate | successful tracheal intubation at the first attempt, compared to more than one attempt | at intubation in 60 seconds | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time to ventilation | From Insertion of the blase into the mouth until first ventilation | at intubation in 120 seconds | 
| Cormack and Lehane Classification | after insert the device the user describe the glottis visualisation | at intubation in 120 seconds | 
| Overall success rate | after two attempts using defined rescue techniques (e.g. rigid stylet, laryngeal mask) | at intubation in 120 seconds | 
| Subjective Training Process | after 25 intubation attempts | at one month |
