Protection afforded by respirators when performing endotracheal intubation using a direct laryngoscope, GlideScope®, and i-gel® device: A randomized trial

Kang H, Lee Y, Lee S, Song Y, Lim TH, Oh J, Lee J, Shin H. PLoS One. 2018 Apr 19;13(4):e0195745

This study carried out an investigation on the use of two respirators (fold- and cup-type) by physicians (n=26) as protection against infections during intubation procedures with three different devices (DL, GlideScope and i-gel). Results showed a lower protection level when wearing the cup-type respirator during intubation with DL (75%) compared to GlideScope (100%) and i-gel (100%). Therefore, the type of airway device selected for intubation may impact on the level of protection of certain types of respirators. However, due to the limited number of respirators tested and the small sample size, additional larger studies are needed to validate these results.

A comparison of various supraglottic airway devices for fiberoptical guided tracheal intubation

Metterlein T, Dintenfelder A, Plank C, Graf B, Roth G. Rev Bras Anestesiol. 2017 Mar - Apr;67(2):166-171

Random assignment of 52 adult patients to different supraglottic devices, from: Laryngeal Tube, LMA, i-gel, LMA Unique, LMA Supreme and Aura-once. After successful ventilation, device positioning was examined to assess glottic opening. Glottic view ranged from 40% for Laryngeal Tube to 90%, with i-gel recording 70%.

An observational study using Tracheal intubation Assisted by Bronchoscopy And Sad during Continuous Oxygenation (TABASCO) method through the i-gel. Easy intubation was secured in all patients with no adverse events recorded.

I-gel O2 resus pack, a rescue device in case of severe facial injury and difficult intubation

Baratto F, Gabellini G, Paoli A, Boscolo A. Am J Emerg Med. 2017 Jan 26

Report of two cases of attempted suicide by firearm managed with the use of the i-gel O2 Resus Pack. In both patients, laryngoscopy attempts failed before an i-gel was inserted and either fibreoptic-assisted intubation or fibreoptic bronchoscopy were performed. Authors conclude that the i-gel's properties mean the device could easily be used by untrained rescuers and might perform an important role during out-of-hospital emergency.

Fiberoptic-guided intubation after insertion of the i-gel airway device in spontaneously breathing patients with difficult airway predicted: a prospective observational study

Arévalo-Ludeña J, Arcas-Bellas JJ, Alvarez-Rementería R, Alameda LE. J Clin Anesth. 2016 Dec;35:287-292

After i-gel insertion in 85 adult patients, general anaesthesia was induced to place an endotracheal tube by fibreoptic bronchoscope. i-gel insertion time, intubation time and oxygen saturation were monitored. Authors conclude this to be a safe and effective technique.
