This study set out to determine the efficacy of blind intubation by novice physicians using the i-gel and the Air-Q devices. Prior the study, a training session focused on anatomy, physiology and pathophysiology of the airways, as well as methods for airway control was provided to all participants. The novice physicians were randomly assigned to either the i-gel or the Air-Q. Several parameters were assessed including time to intubation (primary outcome), time to secure the airway, efficacy of blind intubation and difficulty of the procedure (measured in visual-analogue scale or VAS). Results showed that the time for airway management was 6.5 seconds for the i-gel and 11 seconds for the Air-Q. Time to intubation was significantly shorter when using the i-gel as compared to the Air-Q. Moreover, the effectiveness of intubation was 90% for the i-gel and 78% for the Air-Q. i-gel also had a lower VAS score, and the majority of the participants preferred it to the Air-Q. Therefore, these results suggest that the i-gel represents a better choice for blind intubation by novice physicians when performing CPR.
