i-gel® from Intersurgical: clinical evidence listing

A comprehensive list of all known published clinical evidence on the device

Comparison of the i-gel™ and the Laryngeal Mask Airway Classic™ in terms of clinical performance

Polat R, Aydin GB, Ergil J, Sayin M, Kokulu T, Ozturk I. Braz J Anesthesiol. 2015 Sep-Oct;65(5):343-8

Performance of i-gel vs LMA Classic was measured in 120 patients, with respect to successful insertion attempts, insertion time, peak airway pressure, regurgitation, fibreoptic glottic view and postoperative complications. i-gel gave a shorter insertion time and better fibreoptic view.

Comparison of Second-Generation Supraglottic Airway Devices (i-gel versus LMA ProSeal) During Elective Surgery in Children

Sanket B, Ramavakoda CY,Nishtala MR, Ravishankar CK, Ganigara A. AANA J. 2015 Aug;83(4):275-80

Study to compare efficacy of each device on patients aged up to 10 years. Ease of insertion, time to insertion and oropharyngeal leak pressure were some of the measurements taken. Insertion time was significantly faster with i-gel.

I-gel Versus LMA-Fastrach Supraglottic Airway for Flexible Bronchoscope-Guided Tracheal Intubation Using a Parker (GlideRite) Endotracheal Tube: A Randomized Controlled Trial

Moore A, Gregoire-Bertrand F, Massicotte N, Gauthier A, Lallo A, Ruel M, Todorov A, Girard F. Anesth Analg. 2015 Aug;121(2):430-6

120 patients were randomly assigned to i-gel or LMA Fastrach groups, with tracheal intubation and mask insertion success rate measured. Use of i-gel as a conduit in this scenario is equivalent to Fastrach, however gives shorter intubation times and a better visualisation of the glottic opening.

Propofol requirement for insertion of I-gel versus laryngeal mask airway: A comparative dose finding study using Dixon's up-and-down method

Ashay NA, Wasim S, Anil TB. J Anaesthesiol Clin Pharmacol. 2015 Jul-Sep;31(3):324-8

This randomised controlled trial compared propofol requirements for i-gel and LMA Classic when inserted 60 seconds after injection. i-gel required a significantly lower dose.

A randomized controlled trial of the effect of preoperative dexmedetomidine on the half maximal effective concentration of propofol for successful i-gel insertion without muscle relaxants

Jang YE, Kim YC, Yoon HK, Jeon YT, Hwang JW, Kim E, Park HP. J Anesth. 2015 Jun;29(3):338-45

37 patients were randomly allocated to either a dexmedetomidine or control (saline) group. Authors conclude that preoperative dexmedetomidine reduced the EC50 of propofol.
