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.

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.

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.

I-gel Laryngeal Mask Airway Combined with Tracheal Intubation Attenuate Systemic Stress Response in Patients Undergoing Posterior Fossa Surgery.

Tang C, Chai X, Kang F, Huang X, Hou T, Tang F, Li J. Mediators Inflamm. 2015;2015:965925

Patients were allocated to either tracheal tube intubation or i-gel facilitated intubation groups, with haemodynamic profile, oxidative response and aneasthesia recovery parameters measured. Using i-gel combined with an endotracheal tube in this scenario proved safe and effective, 'leading to uneventful recovery'.

A randomized comparison between the i-gel™ and the air-Q™ supraglottic airways when used by anesthesiology trainees as conduits for tracheal intubation in children

Jagannathan N, Sohn L, Ramsey M, Huang A, Sawardekar A, Sequera-Ramos L, Kromrey L, De Oliveira GS. Can J Anaesth. 2015 Jun;62(6):587-94

96 children aged one month to six years were randomised into either i-gel or air-Q groups, with time to successful tracheal intubation the primary end point. Both served as effective conduit devices in this scenario.
