i-gel® from Intersurgical: clinical evidence listing

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

New single use supraglottic airway device with non-inflatable cuff and gastric tube channel

Siddiqui AS, Ahmed J, Siddiqui SZ, Haider S, Raza SA. J Coll Physicians Surg Pak. 2012; 22(7): 419-23

An experimental study using i-gel® on 100 female patients undergoing elective gynaecologic surgery was performance-measured on ease of insertion, time to insert, peak airway pressure and leak pressure. A gastric tube was placed in each patient. Pharyngolaryngeal morbidities were also recorded. In 92% of patients, i-gel® was inserted successfully first time and there were no instances of blood on the device post-procedure. Authors confirm the i-gel® is a simple and easy to use device.

Randomized crossover comparison of the laryngeal mask airway classic with i-gel® laryngeal mask airway in the management of difficult airway in post burn neck contracture patients

Singh J, Yadav MK, Marahatta SB, Shrestha BL. Indian J Anaesth 2012; 56(4): 348-52

Prospective, crossover, randomised trial of i-gel® against cLMA on 48 post-burn neck contracture patients with reduced neck movement and mouth opening. Primary outcome was overall success rate, with other measurements taken in time to ventilation, leak pressure, fibreoptic view and visualisation of square wave pattern. Success rate for i-gel® was 91.7%, against 79.2% for cLMA. i-gel® outperformed cLMA in all measurements. Authors conclude their study has ‘better clinical performance in the difficult airway management of the airway in the post burn contracture of the neck’.

Tracheal intubation through i-gel® conduit in a child with post-burn contracture

Gupta Richa, Gupta Ruchi, Wadhawan S, Bhadoria P. J Anaesth Clin Pharmacol 2012; 28(3): 397–398

Report of i-gel® (size 2.5) used as a conduit for intubation on a nine-year-old girl scheduled for post-burn contracture with limited neck extension. Spontaneous ventilation and depth of anaesthesia were maintained, even after removal of the i-gel®. Authors conclude that fibreoptic ventilation through i-gel® is a ‘highly successful technique’.

General anesthesia in a case of right-sided aortic arch with Kommerell’s diverticulum diagnosed on preoperative examination

Nakano S, Uda R, Nakajima O, Yamamoto N, Akatsuka M. Masui 2012; 61(7): 765-8

Case of the use of i-gel as preferred airway device and vehicle for tracheal intubation in a 59-year-old male with known Kommerell’s diverticulum, scheduled for repair of a tibial fracture under general anaesthesia. The i-gel® resulted in an uneventful operation with both controlled and spontaneous respiration, and the authors’ conclude that i-gel® is a useful device in such specific cases.
