i-gel® from Intersurgical: clinical evidence listing

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

A comparison of the I-Gel supraglottic device with endotracheal intubation for bronchoscopic lung volume reduction coil treatment

Arevalo-Ludeña J, Arcas-Bellas JJ, Alvarez-Rementería R, Flandes J, Morís L, Muñoz Alameda LE. J Clin Anesth. 2016 Jun;31:137-41

Prospective observational study on 22 patients comparing the use of i-gel against orotracheal intubation. Tidal volume, peak pressure, gas leaks and adverse events were recorded. Authors conclude i-gel is 'an effective and safe alternative' to OTI in this scenario.

Spatial relationship of I-gel and Ambu® AuraOnce on pediatric airway: a randomized comparison based on three dimensional magnetic resonance imaging

Aqil M, Delvi B, Abujamea A, Alzahrani T, Alzahem A, Mansoor S, Aaljazaeri A. Minerva Anestesiol. 2016 Jun 17

Sixty paediatric patients were split between the two groups, with scans of head and neck performed after confirmation of device placement. Both devices 'significantly' reduced the area of glottis opening. i-gel produced greater dilation of upper oesophogeal sphincter. Authors conclude more studies needed to test these results to 'reduce morbidity on pediatric airway'.

Comparison of remifentanil EC50 for facilitating i-gel and laryngeal mask airway insertion with propofol anesthesia

Choi JB, Kwak HJ, Lee KC, Lee SR, Lee SY, Kim JY. J Anesth. J Anesth. 2016 Jun;30(3):377-83

Randomised study comparing 41 female patients across two groups: i-gel and LMA, undergoing anaesthesia. EC50 of remifentanil concentration for i-gel insertion was significantly lower.

Comparison of oropharyngeal leak pressure and clinical performance of LMA ProSeal™ and i-gel® in adults: Meta-analysis and systematic review

Shin HW, Yoo HN, Bae GE, Chang JC, Park MK, You HS, Kim HJ, Ahn HS. J Int Med Res. 2016 Jun;44(3):405-18

Online searches of popular databases resulted in 14 randomised controlled trials being included. Overall, leak pressure was higher with ProSeal, but i-gel was faster to insert, had lower incidence of blood staining on removal and sore throat.

Evaluation of six different airway devices regarding regurgitation and pulmonary aspiration during cardio-pulmonary resuscitation (CPR) – A human cadaver pilot study

Piegeler T, Roessler B, Goliasch G, Fischer H, Schlaepfer M, Lang S, Ruetzler K. Resuscitation 2016 May;102:70-4

Randomised human cadaver study comparing Laryngeal Tube, EasyTube, LMA Classic, i-gel, ETI and BVM effect on protection against regurgitation and aspiration during CPR. Five minutes of CPR was administered according to 2010 European Resuscitation Council Guidelines. Aspiration was detected in two out of five cadavers with i-gel, while none were recorded when using ETI. Study provides experimental evidence that ETI offers superior protection during CPR.
