i-gel as an intubation conduit: Comparison of three different types of endotracheal tubes

Choudhary N, Kumar A, Kohli A, Wadhawan S, Bhadoria P. Indian J Anaesth. 2019 Mar;63(3):218-224

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.

Comparison Of The I-Gel Supraglottic And King Laryngotracheal Airways In A Simulated Tactical Environment.

March JA, Tassey TE, Resurreccion NB, Portela RC, Taylor SE. Prehosp Emerg Care. 2018 May-Jun;22(3):385-389.

The aim of this study was to compare the performance of the I-Gel airway (IGA) to the King LT laryngotracheal airway (KA) in a simulated tactical scenario. The evaluation was carried out by assessing the time to successful tube placement on a manikin. Participants were also videomonitored to assess their height exposure above the protection barrier. Finally, participants were questioned on which device they preferred with results favouring i-gel.

Endotracheal intubation versus supraglottic airway placement in out-of-hospital cardiac arrest: a meta-analysis

Benoit et al. Resuscitation. 2015 Aug;93:20-6

A literature search was carried out in PubMed, Scopus, and the Cochrane database. Studies where intubation and SADs were compared in prehospital cardiac arrest patients were found and a meta-analysis was carried out. Outcomes measured were ROSC, survival to hospital admission, survival to hospital discharge, and neurologically intact survival until discharge.
