Twenty anaesthesiologists from the Air Ambulance Department at Oslo University Hospital used i-gel®, laryngeal tube LTSII™ and Macintosh laryngoscopes in two scenarios with either unrestricted (scenario A) or restricted (scenario B) access to the cranial end of the manikin. Technique selected, success rates and time to completion were primary outcomes. Results showed that in scenario B, all physicians secured the airway on first attempt, compared to 80% for ETI, whilst also completing in a quicker time. Authors conclude that ‘ETI was time consuming and had a low success rate’.
