Study on tracheal intubation in manikins and patients with a camera embedded in the tip of the tracheal tube Vivasight™ pre-loaded in a size 5 i-gel®. All attempted intubations were successful, with a mean time of 1.4 seconds, and was faster when compared to intubation via LMA®.

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

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.

Six different supraglottic airway devices, including i-gel®, were tested by 58 paramedics for speed and ease of insertion in a manikin, whilst wearing either a standard uniform or chemical, biological, radiation, nuclear-person protective equipment (CBRN-PPE). During the latter test, i-gel® was the fastest of the six to insert with a mean insertion time of 19 seconds. Overall, the wearing of CBRN-PPE has a detrimental effect on insertion time of supraglottic airways.

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.
