Comparison between supraglottic airway devices and endotracheal tubes in patients undergoing laparoscopic surgery: A systematic review and meta-analysis

Park SK, Ko G, Choi GJ, Ahn EJ, Kang H. Medicine (Baltimore). 2016 Aug;95(33):e4598

In total, 17 randomised controlled trials were identified fitting the parameters outlined. Incidence of postoperative complications including cough at removal, dysphagia, sore throat and laryngospasm were higher in the ETT group. However no differences were shown regarding insertion success at first attempt and insertion time, among others.

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.

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%.
