Randomised comparison of the effectiveness of the laryngeal mask airway supreme, i-gel and current practice in the initial airway management of out of hospital cardiac arrest (REVIVE-Airways): a feasibility study

Benger J, Coates D, Davies S, Greenwood R, Nolan J, Rhys M, Thomas M, Voss S. Br J Anaesth. 2016;116(2):262-8

A cluster randomised trial of paramedics within one ambulance service in England over a 12-month period, split into groups using either the i-gel or LMA Supreme or usual practice for all patients with non-traumatic adult OHCA. Primary outcome was study feasibility, including recruitment and protocol adherence. Secondary outcomes included survival to hospital discharge and to 90 days. 184 of 535 paramedics consented, with 615 patients recruited. The LMA Supreme arm was suspended following 'adverse incidents'. No differences were reported in secondary outcomes.

Pillow height for i-gel® insertion: a randomized clinical trial

Fujiwara A, Komasawa N, Minami T. J Anesth. 2016;30(3):542

Randomised controlled trial of 70 patients divided into two groups by height: low (4cm), and high (12cm). Performed by novice doctors, insertion efficacy difference between groups did not differ.

Assessment of suitability of i-gel and laryngeal mask airway-supreme for controlled ventilation in anesthetized paralyzed patients: A prospective randomized trial

Radhika KS, Sripriya R, Ravishankar M, Hemanth Kumar VR, Jaya V, Parthasarathy S. Anesth Essays Res. 2016;10(1):88-93

Patients were split into i-gel and LMA Supreme groups, with insertion attempts, time and any manoeuvres needed forming outcomes, along with peak inspiratory pressure (PIP).  LMA-S was inserted successfully in more patients, but with no significant difference in PIP.

Evaluation of the efficacy of six supraglottic devices for airway management in dark conditions: a crossover randomized simulation trial

Ohchi F, Komasawa N, Imagawa K, Okamoto K, Minami T. J Anesth. 2015 Dec;29(6):887-92

15 novice doctors and 17 with >2 years experience were asked to insert each airway device into a manikin in random order. This was done in a windowless room with all the lights on and again with the lights switched off. Insertion time, insertion success, and participant's own perception of ease of use were all recorded. Ventilation success was lower in both groups when using the ProSeal and cLMA in the dark. Insertion time for these devices was longer in the dark, an effect that was also seen in both groups. Both ProSeal and cLMA were rated as more difficult to use in the dark compared with light conditions and with other devices. These results are thought to be due to the difference in design between these airways and the others used in the study, which are stiffer and anatomically shaped.
