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.

In a difficult access scenario, supraglottic airway devices improve success and time to ventilation

Wetsch WA, Schneider A, Schier R, Spelten O, Hellmich M, Hinkelbein J. Eur J Emerg Med. 2015 Oct;22(5):374-6

Manikin study to assess speed of effective ventilation administered in a simulated motor vehicle accident victim, comparing i-gel against tracheal intubation, Ambu AuraOnce and laryngeal tube. Fastest effective ventilation achieved with i-gel.

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.

A comparison of fibreoptic-guided tracheal intubation through the Ambu ® Aura-i ™, the intubating laryngeal mask airway and the i-gel ™: a manikin study

de Lloyd LJ, Subash F, Wilkes AR, Hodzovic I. Anaesthesia. 2015 May;70(5):591-7

Thirty anaesthesists each performed two tracheal intubations through each device. i-gel was the quickest device, with no failed intubation reported, compared to six for the Aura-I.

Performance of intubation with 4 different airway devices by unskilled rescuers: manikin study

Lee DW, Kang MJ, Kim YH, Lee JH, Cho KW, Kim YW, Cho JH, Kim YS, Hong CK, Hwang SY. Am J Emerg Med. 2015 May;33(5):691-6

LMA Classic, i-gel, PENTAX Airway Scope and Macintosh laryngoscope were all tested, with time to ventilation, intubation success rate and difficulty of intubation measured. Authors conclude that intubation with i-gel was faster and easier.
