Taylor J, Black S, Brett S, Kirby K, Nolan JP, Reeves BC, Robinson M, Rogers CA, Scott LJ, South A, Stokes EA, Thomas M, Voss S, Wordsworth S, Benger JR. Resuscitation. 2016 Sep 30. pii: S0300-9572(16)30476-2

Patient enrollment began in June 2015 for this study comparing the use by paramedics of the i-gel against endotracheal intubation in OHCA in the UK. The primary outcome is the modified Rankin Scale score at hospital discharge. The trial will enrol 9070 patients over two years.

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.

An exploration of the views of paramedics regarding airway management

Brandling J, Rhys M, Thomas M, Voss S, Davies S, Benger J. Scand J Trauma Resusc Emerg Med. 2016; 24: 56

A study within a UK ambulance study exploring the customs and beliefs or paramedics in relation to airway management and whether tracheal intubation sustains professional identity. Interviews were conducted with 17 participants, which identified four key factors: pride, utility, expectations and professionalisation. Authors conclude the interviews identified a 'wide range of views' on airway management based on evidence and experience.

Airway management in out-of-hospital cardiac arrest in Finland: current practices and outcomes

Hiltunen P, Jäntti H, Silfvast T, Kuisma M, Kurola J. Scand J Trauma Resusc Emerg Med. 2016; 24: 49

Data on patients with OHCA and attempted resuscitation in an area of Finland over a six-month period in 2010 was collected, with airway techniques and adverse events recorded. Of the 614 patients, 67% were treated with endotracheal intubation and 30% with supraglottic airway devices.  Overall survival to hospital discharge was 17.8%.

i-gel as alternative airway tool for difficult airway in severely injured patients

Häske D, Schempf B, Niederberger C, Gaier G. Am J Emerg Med. 2016;34(2):340

Report of two cases where i-gel was successfully used in a prehospital setting on patients with severe head and neck trauma. Authors suggest that, on evidence, i-gel is an 'appropriate primary airway tool'.
