Supraglottic Airway Devices and Effect on Voice-Comparison of LMA Proseal and i-gel: Double-Blind Randomized Clinical Trial

Vaidya S, Kundra P, Gopalakrishnan S, Parida P, Yuvaraj K, Mohan PM. J Voice. 2016 Sep;30(5):631-7

90 adult patients were randomly assigned to LMA Proseal and i-gel groups, with voice evaluated using perceptive and acousitc analysis. In both groups voice results deteriorated comparably.

Layperson mouth-to-mask ventilation using a modified I-gel laryngeal mask after brief onsite instruction: a manikin-based feasibility trial

Schälte G, Bomhard LT, Rossaint R, Coburn M, Stoppe C, Zoremba N, Rieg A. BMJ Open 2016;6(5):e10770

100 participants were analysed using a labelled i-gel with an integrated mouthpiece and asked to follow an instruction chart. 79% were able to ventilate the manikin effectively, with 90% using the correct turn and direction.

Sniffing Position and i-gel Rotation Approach for i-gel Insertion under General Anesthesia

Takahashi Y, Murashima K, Kayashima K. Masui 2016 Apr;65(4):330-5

Study on 50 adults to test the efficacy of i-gel insertion assistance techniques - sniffing the morning air position and rotation. Average insertion time was 24 seconds at first attempt. Authors conclude both techniques 'can be used for insertion'.

Pressure support ventilation with the I-gel in intensive care unit: case report

Akan B, Erdem D, Albayrak MD, Aksoy E, Akdur F, Gogus N. Braz J Anesthesiol. 2016;66(2):219-21

This case report described the use of the i-gel for the management of ventilation in an ICU patient. A 49-year-old woman was hospitalized in ICU due to fever and respiratory distress. Three intubations using a bougie failed, but the airways were subsequently secured with an i-gel (size 3) at the first attempt. No issues were seen in mechanical ventilation using the i-gel for 48 hours in pressure-controlled ventilation. Thus, the i-gel can be used in difficult intubation scenarios, allowing mechanical ventilation up to 48 hours.
