Endotracheal intubation versus supraglottic airway placement in out-of-hospital cardiac arrest: a meta-analysis

Benoit et al. Resuscitation. 2015 Aug;93:20-6

A literature search was carried out in PubMed, Scopus, and the Cochrane database. Studies where intubation and SADs were compared in prehospital cardiac arrest patients were found and a meta-analysis was carried out. Outcomes measured were ROSC, survival to hospital admission, survival to hospital discharge, and neurologically intact survival until discharge.

Comparison of the i-gel and other supraglottic airways in adult manikin studies: systematic review and meta-analysis

An J, Nam SB, Lee JS, Lee J, Yoo H, Lee HM, Kim MS. Medicine (Baltimore). 2017 Jan;96(1):e5801

Authors conducted a specialised search of study databases for eligible randomised controlled trials, setting device insertion time and first-attempt insertion success rate as their primary outcomes. In the 14 RCTs included, i-gel was faster than the majority of other supraglottic airways, with only three others recording shorter insertion times. Authors concluded that the 'unapparent advantage' of insertion success rate indicated the need for further evidence gathering in this area.

Laryngeal mask airway ProSeal provides higher oropharyngeal leak pressure than i-gel in adult patients under general anesthesia: a meta-analysis

Maitra S, Baidya DK, Arora MK, Bhattacharjee S, Khanna P. J Clin Anesth. 2016 Sep;33:298-305

Meta-analysis of 10 RCTs to assess results when comparing the oropharyngeal leak pressure of each device. LMA ProSeal returned more favourable results, although i-gel deemed easier to insert. ProSeal also reported higher blood staining.

Comparison between supraglottic airway devices and endotracheal tubes in patients undergoing laparoscopic surgery: A systematic review and meta-analysis

Park SK, Ko G, Choi GJ, Ahn EJ, Kang H. Medicine (Baltimore). 2016 Aug;95(33):e4598

In total, 17 randomised controlled trials were identified fitting the parameters outlined. Incidence of postoperative complications including cough at removal, dysphagia, sore throat and laryngospasm were higher in the ETT group. However no differences were shown regarding insertion success at first attempt and insertion time, among others.

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.
