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.

Current practice patterns of supraglottic airway device usage in paediatric patients amongst anaesthesiologists: A nationwide survey.

Jain RA, Parikh DA, Malde AD, Balasubramanium B. Indian J Anaesth. 2018 Apr;62(4):269-279

This survey was sent to over 16,000 members of the Indian Society of Anaesthesiologists and given to delegates at the Asian Society of Paediatric Anaesthesiologists conference 2017. Percentage, mean and standard deviation were calculated. Results showed i-gel was the most commonly used device (60%) and 75% of respondents had access to second-generation supraglottic airways.

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.

Success rate of airway devices insertion: laryngeal mask airway versus supraglottic gel device.

Pournajafian A, Alimian M, Rokhtabnak F, Ghodraty M, Mojri M. Anesth Pain Med. 2015 Mar 30;5(2):e22068.

61 patients were randomised for cLMA or I-gel insertion for brief orthopaedic surgery. Insertion time, success/failure rate, and incidence of complications (sore throat, hoarseness, bleeding) were all recorded. The devices were comparable, with a low incidence of complications overall and no instances of blood in the airway or on the device. The I-gel is therefore an acceptable alternative to the LMA Classic.
