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 investigation aimed to compare the successful intubation rate of the i-gel using three types of endotracheal tubes (ETTs). 75 ASA I and II patients (age 18-60 years) undergoing elective surgery under general anaesthesia were randomly assigned into three groups based on the type of endotracheal ETT, which included polyvinyl chloride ETT (Group P), intubating laryngeal mask airway ETT (Group I) and flexometallic ETT (Group F). Recorded parameters included time taken for successful intubation, success rate, number of attemps, manoeuvres, and complications. Results demonstrated that Group P had the lowest time and mean time for intubation, as well as the highest first attempt and overall intubation success rate. Therefore, the combination of polyvinyl chloride ETT with i-gel to intubate patients with difficult airways represents the most successful approach compared to other combinations. However, additional studies are needed to validate these results.
