Postoperative sore throat: a systematic review

El-Boghdadly K, Bailer R, Wiles M. Anaesthesia 2016;71(6):706-17

Review into prevalence of sore throat after use of supraglottic airway devices against tracheal intubation in general anaesthesia. Authors suggest that, in adults, i-gel results in a lower incidence of post-operative sore throat.

The i-gel Supraglottic Airway as a Conduit for Fibreoptic Tracheal Intubation - A Randomized Comparison with the Single-use Intubating Laryngeal Mask Airway and CTrach Laryngeal Mask in Patients with Predicted Difficult Laryngoscopy

Michálek P, Donaldson W, McAleavey F, Abraham A, Mathers RJ, Telford C. Prague Med Rep. 2016;117(4):164-175

Comparative study of three supraglottic airways as conduits in patients with predicted difficult laryngoscopy. Primary outcome measure was success rate of tracheal intubation through the device. No statistical difference was recorded in success rates between devices, however i-gel proved quicker to insert compared to ILMA and the intubation time was shorter compared to CTrach. i-gel is a suitable alternative to sILMA and CTrach in this scenario, and the shorter times recorded may provide an advantage in cases of difficult oxygenation.

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.

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.
