i-gel® from Intersurgical: clinical evidence listing

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

Sore throat following three adult supraglottic airway devices

L'Hermite J, Dubout E, Bouvet S, Bracoud LH, Cuvillon P, Coussaye JE, Ripart J. Eur J Anaesthesiol. 2017 Jul;34(7):417-424

Comparison of the incidence of sore throat in 546 patients following use of LMA Unique, LMA Supreme and the i-gel. Primary outcome was incidence 24 hours postoperatively. Authors concluded that recordings were not significantly different between the three devices.

Ambu AuraOnce versus i-gel laryngeal mask airway in infants and children undergoing surgical procedures. A randomized controlled trial

Alzahem AM, Aqil M, Alzahrani TA, Aljazaeri AH. Saudi Med J. 2017 May;38(5):482-490

Randomised assignment of 112 patients to either AuraOnce or i-gel groups in which oropharyngeal leak pressure, ease of insertion and fibreoptic viewing were measured. i-gel recorded more favourable leak pressures and superior fibreoptic viewing.

Are nurses able to perform blind intubation? Randomized comparison of I-gel and laryngeal mask airway

Ladny JR, Bielski K, Szarpak L, Cieciel M, Konski R, Smereka J. Am J Emerg Med. 2017 May; 35(5): 786-787

Manikin study to assess effectiveness of blind intubation through the i-gel, LMA Classic and a standard cuffed tracheal tube, performed by 34 nurses in CPR conditions across two scenarios (with and without chest compressions). Primary measure was time to intubation. i-gel recorded a lower median time to intubation and higher, statistically significant, successful insertion rates in both scenarios. Performing compressions doesn't significantly affect time to perform blind intubation in this setting, but reduces the effectiveness of first intubation attempt. i-gel was faster in both scenarios.

Comparison of the Macintosh laryngoscope and blind intubation via the iGEL for intubation with cervical spine immobilization: A randomized, crossover, manikin trial

Gawlowski P, Smereka J, Madziala M, Szarpak L, Frass M, Robak O. Am J Emerg Med. 2017 Mar; 35(3): 484-487.

Paramedics performed standard intubation and blind intubation in three airway scenarios. Results show that blind intubation with the i-gel was superior to ETI performed by paramedics.

Calling the patient's own name facilitates recovery from general anaesthesia: a randomised double-blind trial

Jung YS, Paik H, Min SH, Choo H, Seo M, Bahk JH, Seo JH. Anaesthesia. 2017 Feb;72(2):197-203.

Random allocation of patients into two groups: one with a name-specific verbal command and one using a general term. Time to i-gel removal was quicker in the name group.
