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.

Comparison of Four Different Supraglottic Airway Devices in Terms of Efficacy, Intra-ocular Pressure and Haemodynamic Parameters in Children Undergoing Ophthalmic Surgery

Peker G, Takmaz SA, Baltacı B, Başar H, Kotanoğlu M. Turk J Anaesthesiol Reanim. 2015 Oct;43(5):304-12

Prospective, randomised study on 60 children aged 1-10 years. Insertion attempts and ease, leak pressure and complications were recorded. Results suggest no difference between the devices under these conditions.

Comparison of I-gel with Classic Laryngeal Mask Airway Regarding the Ease of Use and Clinical Performance

Arı DE, Ar AY, Karip CŞ, Siyahkoç İ, Arslan AH, Akgün FN. Turk J Anaesthesiol Reanim. 2015 Oct;43(5):299-303

Insertion time and successful first attempt incidence were measured within the 50 patients assigned to the device groups. i-gel was quicker to insert with other results 'did not differ'. Authors conclude i-gel may be 'a more advantageous' device compared with LMA.

Comparison of three supraglottic airway devices for airway rescue in the prone position: A manikin-based study

Gupta B, Gupta S, Hijam B, Shende P, Rewari V. J Emerg Trauma Shock. 2015 Oct-Dec;8(4):188-92

Insertion of i-gel, ProSeal and LMA Classic were studied in prone position. Time to insertion, ease of insertion, bronchoscopic view an insertion score were compared. i-gel was the quickest and easiest to insert.

Effect of pneumoperitoneum and Trendelenberg position on oropharyngeal sealing pressure of I-gel™ and ProSeal LMA™ in laparoscopic gynecological surgery: A randomized controlled trial

Mishra SK, Sivaraman B, Balachander H, Naggapa M, Parida S, Bhat RR, Yuvaraj K. Anesth Essays Res. 2015 Sep-Dec;9(3):353-8

60 patients were enrolled to either i-gel or ProSeal groups, with the primary objective to compare sealing pressure. Authors conclude ProSeal gave a better seal.
