The quality of cardiopulmonary resuscitation using supraglottic airways and intraosseous devices: a simulation trial

Reiter DA, Strother CG, Weingart SD. Resuscitation 2013; 84(1): 93-7

Emergency Medicine residents split into teams took part in two simulated ventricular fibrillation cardiac arrests using a high fidelity simulator, testing whether use of a laryngeal mask airway improved resuscitation results. Time to airway placement, duration and success rate of airway placement and percent hands off time were among results measured. Authors conclude that use of a laryngeal mask and an IO device led to ‘significantly faster establishment of an airway’

Abstract

Supraglottic Airway Device preference and insertion speed in F1 doctors

Adlam M, Purnell D. Resuscitation 2012; 83(5): e129

Twenty-one Foundation Year One Trainees were asked to attempt to ventilate a manikin with either an LMA or i-gel®, of their own choosing. Results showed 71% chose to use an LMA, although on reflection 95% preferred the i-gel®. Speed of insertion was faster with i-gel®. Study supports use of i-gel® on resus trolleys for use by non-airway trained doctors.

LMA Supreme® vs i-gel®--a comparison of insertion success in novices

Ragazzi R, Finessi L, Farinelli I, Alvisi R, Volta CA. Anaesthesia 2012; 67(4): 384-8

Following a short lecture and manikin training, novice airway users were randomly selected to insert either the LMA Supreme® or i-gel® into 80 patients undergoing breast surgery, to measure insertion success rate and ventilation profile.

Hands-off time during insertion of six airway devices during cardiopulmonary resuscitation: A randomised manikin trial

Ruetzler K, Gruber C, Nabecker S, Wohlfarth P, Priemayr A, Frass M, Kimberger O, Sessler D, Roessler B. Resuscitation 2011; 82(8): 1060-1063

After an audio-visual lecture and practical demonstration, 40 voluntary emergency medical technicians with limited airway management experience were recruited to perform airway management with six devices, including the i-gel®, during sustained compressions on manikins. Hands-off time was significantly longer when inserting a traditional endotracheal tube, whereas the supraglottic devices were inserted successfully on each occasion.

Evaluation of four airway training manikins as patient simulators for the insertion of eight types of supraglottic airway devices

Jackson KM, Cook TM. Anaesthesia. 2007 Apr;62(4):388-93

The airway arm of this trial compared devices including i-gel, Cobra, SLIPA and Laryngeal Tube Suction II. Each device was inserted twice into each manikin by ten anaesthetists, with each insertion scored and ranked. No one manikin outranked the others for all devices. i-gel insertion was 'significantly the easiest'.
