3.2. Scenario B
The successful rate of first attempt intubation in a difficult environment by inexperienced was 73,3% for INT and 50% for conventional laryngoscope. Overall effectiveness was 83,3% and 86,7%, respectively (Fig. Intubation with conventional laryngoscope versus intubrite laryngoscope by inexperienced participants in difficult pre-hospital.The successful rate of first attempt intubation in the experienced group was 86,7% with INT compared to 60% with a conventional laryngoscope in difficult settings. Overall effectiveness was 96,7% for both devices (Fig. Intubation with conventional laryngoscope versus intubrite larngoscope by experienced participants in difficult pre-hospital settings.Such devices as intubrite provide better working conditions and make up for deficiencies in successful tracheal intubation by inexperienced participants in a normal and difficult environment where successful tracheal intubation is highly correlated with the number of attempts. Participants were more effective in the second and third attempts. The correlation was less significant in the intubrite group.Tracheal intubation with intubrite was more effective in the experienced group. The first-attempt intubation effectiveness performed by skilled participants was higher with both devices. Like in the inexperienced group, successful intubation correlated with a number of attempts. The efficacy of tracheal intubation with intubrite was also higher in the experienced group.
