This manikin study aimed to compare the performance of several supraglottic airway devices (SADs) in different blind intubation scenarios performed by 116 inexperienced physicians. The devices used included i-gel, Air-Q laryngeal airway and Ambu AuraGain. The three devices were tested on a paediatric manikin in three different scenarios, which included normal airway without chest compressions (A), normal airway with continuous chest compressions plus the CORPLUS CPR system (CCS) (B), and difficult airway with continuous chest compressions plus CCS (C). Parameters assessed in this investigation included first intubation success rate, median time to SAD placement, time to endotracheal intubation, as well as ease of intubation. Results have shown that the i-gel performed better in every scenario and in all parameters tested as compared to the other devices. Therefore, these data demonstrated that the i-gel is the most effective device for emergency blind intubation performed by inexperienced physicians in paediatric patients.

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.
