Non-Conventional Utilization of the Aintree Intubating Catheter to Facilitate Exchange Between Three Supraglottic Airways and an Endotracheal Tube: A Cadaveric Trial.

Lopez NT, McCoy SK, Carroll C, Jones E, Miller JA. Mil Med. 2018 Jun 19 [Epub ahead of print]

Prospective crossover study on cadavers to measure airway exchange on three pre-placed supraglottic airways: King LT, i-gel and LMA Unique. Participants, recruited from emergency medical personnel in a training lab, rated the difficulty level of placement of each airway device. Successful exchange equalled proper placement of the ETT in the trachea. Authors conclude the i-gel superior for blind airway exchange with an ETT in this set up.

Comparison of the Macintosh laryngoscope and blind intubation via the iGEL for intubation with cervical spine immobilization: A randomized, crossover, manikin trial

Gawlowski P, Smereka J, Madziala M, Szarpak L, Frass M, Robak O. Am J Emerg Med. 2017 Mar; 35(3): 484-487.

Paramedics performed standard intubation and blind intubation in three airway scenarios. Results show that blind intubation with the i-gel was superior to ETI performed by paramedics.

Tracheal intubation through I-gel performed during simulated cardiopulmonary resuscitation

Wojewodzka-Zelezniakowicz M, Majer J. Am J Emerg Med. 2017 Jan 16.

Manikin study to compare the efficacy of ETI performed by 27 nurses using the i-gel as a guide with/without chest compressions. Results showed that in this scenario, nurses were able to perform blind intubation using the i-gel with 'high efficiency'.

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%.

Continuous ventilation during intubation through a supraglottic airway device guided by fiberoptic bronchoscopy: a observational assessment

Landsdalen HE, Berge M, Kristensen F, Guttormsen AB, Søfteland E. Acta Anaesthesiol Scand. 2017 Jan;61(1):23-30 

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.
