This randomised crossover study compared the cLMA® to the i-gel® during endotracheal intubation of a manikin. 32 anaesthetists took part in the study. For each device, two intubations took place with the tracheal tube directly over the fibrescope and two used an Aintree Intubation Catheter. Intubation took significantly less time with the i-gel® using both methods. Five oesophageal intubations occurred with the cLMA. Anaesthetists stated a preference for the i-gel® due to the ease of use. The authors conclude that the i-gel® is a more appropriate choice for intubation than the cLMA.
