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 of the clinical performance of i-gel, LMA Supreme and LMA ProSeal in elective surgery

Liew GH, Yu ED, Shah SS, Kothandan H. Singapore Med J 2016; 57(8): 432-437

150 adult patients undergoing general anaesthesia were randomly assigned to 3 groups for ventilation via one of the SADs. Speed and ease of insertion, ease of gastric tube insertion, amount of gastric contents drained, leak pressure, and complications were all recorded. Patients were interviewed 1 and 24h after surgery to determine the incidence and severity of sore throat, hoarseness and dysphagia.

Observation of ventilation effects of I-gel™, Supreme™ and Ambu AuraOnce™ with respiratory dynamics monitoring in small children

Gu Z, Jin Q, Liu J, Chen L. J Clin Monit Comput. 2016 Aug 4. [Epub ahead of print]

105 patients were including in this paediatric study, with primary outcomes including leak pressure and respiratory dynamic data. Authors conclude that the 'i-gel presented a better sealing effect and fewer adverse reactions.'

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.

Retrospective cohort investigation of perioperative upper respiratory events in children undergoing general anesthesia via a supraglottic airway

No HJ, Koo BW, Oh AY, Seo KS, Na HS, Ryu JH, Lee SW. Medicine (Baltimore) 2016 Jul;95(28):e4273.

Observational analysis of medical records of previous anaesthetic procedures at one university hospital. Comparison of the two anaesthetic agents included use of four supraglottic airways: LMA Flexible, LMA Supreme, LarySeal and i-gel.
