Influence of Head and Neck Position on Oropharyngeal Leak Pressure and Cuff Position with the ProSeal Laryngeal Mask Airway and the I-Gel: A Randomized Clinical Trial

Mishra SK, Nawaz M, Satyapraksh MV, Parida S, Bidkar PU, Hemavathy B, Kundra P. Anesthesiol Res Pract. 2015;2015:705869

After induction of anaesthesia and device insertion, head position was ranomly changed from neutral to flexion, extension and lateral rotation. Leak pressure, fibreoptic view and ventilation scores were among the results measured. Effective ventilation can be performed with both devices, but 'extreme precaution' should be taken in flexion position in ProSeal.

Comparison of five 2nd-generation supraglottic airway devices for airway management performed by novice military operators.

Henlin T, Sotak M, Kovaricek P, Tyll T, Balcarek L, Michalek P. Biomed Res Int. 2015;2015:201898

Prospective, randomised, single-blinded study comparing five supraglottic airway devices (ProSeal LMA, Supreme LMA, SLIPA, Laryngeal Tube Suction-D and i-gel) in low light conditions on 505 patients after induction of general anaesthesia. Insertion time was shortest in Supreme LMA and i-gel groups.

A performance comparison of the paediatric i-gel with other supraglottic airway devices.

Smith P, Bailey CR. Anaesthesia. 2015 Jan;70(1):84-92

Review of 62 published articles, including 14 randomised controlled trials, comparing i-gel with other supraglottic airway devices in children. Leak pressure was found to be the most common primary outcome. Authors conclude i-gel is 'at least equivalent' to other devices, and may give higher leak pressures and improved fibreoptic view of the glottis.

Evaluation of i-gel(™) airway in children: a meta-analysis

Maitra S, Baidya DK, Bhattacharjee S, Khanna P. Paediatr Anaesth. 2014 Oct;24(10):1072-9

A total of nine studies were included using search keywords, with results finding that i-gel gave significantly higher leak pressure and ProSeal. Authors conclude it is an effective alternative to ProSeal and cLMA.

i-gel™ in Ambulatory Surgery: A Comparison with LMA-ProSeal™ in Paralyzed Anaesthetized Patients.

Das A, Majumdar S, Mukherjee A, Mitra T, Kundu R, Hajra BK, Mukherjee D, Das B. J Clin Diagn Res. 2014 Mar;8(3):80-4

Ease of insertion and time taken to placement and post-operative complications were measured. i-gel was easier to insert with a shorter insertion time.
