Theiler L, Gutzmann M, Kleine-Brueggeney M, Urwyler N, Kaempfen B, Greif R. Br J Anaesth 2012; 109(6): 990-995

Over a period of 24 months, 2049 uses of the i-gel® were measured across five independent hospitals in Switzerland to evaluate insertion success rates, leak pressures, adverse events, and risk factors for failure. Patients’ mean age was 47 years. The authors concluded that the i-gel® is a reliable device, failing in less than 5% of patients and providing high leak pressures. Serious adverse events are rare.

Randomized clinical trial of the i-gel® and Magill tracheal tube or single-use ILMA® and ILMA® tracheal tube for blind intubation in anaesthetized patients with a predicted difficult airway.

Theiler L, Kleine-Brueggeney M, Urwyler N, Graf T, Luyet C, Greif R. Br J Anaesth 2011; 107(2): 243-250

A prospective, randomised, controlled trial comparing the success rate of blind tracheal intubation with a Magill PVC tube through i-gel®. Corresponding tracheal tube was introduced under fibreoptic visualization, but without guidance. Primary outcome was intubation success rate.
