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.

Evaluation of I-gel™ airway in different head and neck positions in anesthetized paralyzed children

Jain D, Ghai B, Bala I, Gandhi K, Banerjee G. Paediatr Anaesth. 2015;25(12):1248-53

30 children induced with sevoflurane in oxygen and administered atracurium intravenously. Oropharyngeal leak pressure in neutral, maximum flexion and maximum extension were primary outcomes measured. In extreme flexion of head and neck, caution is warranted during ventilation.
