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.

Insertion of six different supraglottic airway devices whilst wearing chemical, biological, radiation, nuclear-personal protective equipment: a manikin study

Castle N, Pillay Y, Spencer N. Anaesthesia 2011; 66(11): 983-8

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.

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.

Performance and skill retention of intubation by paramedics using seven different airway devices – a manikin study

Ruetzler K, Roessler B, Potura L, Priemayr A, Robak O, Schuster E, Frass M. Resuscitation 2011; 82 (5): 593-597

41 paramedics with no previous experience watched a lecture and demonstration. They then attempted to insert each of six supraglottic airways and an ET tube into a manikin in random order. After three months, all participants were assessed again without receiving further training. All supraglottic airways except ProSealTM were more successful than the ET tube. i-gel®, Unique® and LT-DTM had significantly faster times to insertion and ventilation than the other devices. There was no significant difference in success rates for supraglottic airways after three months, however, ET tube insertion rates decreased from 78% to 58% in that time.
