[Tracheal intubation through the intubating laryngeal mask airway training on manikin: comparison of single use and reusable devices from the same manufacturer]. / Apprentissage sur mannequin de l'intubation trachéale à l'aide d'un masque laryngé pour l'intubation : comparaison des dispositifs réutilisables et à usage unique d'un même fabricant.

ABSTRACT

INTRODUCTION: Recently, the French Society for Anaesthesia and Intensive Care (SFAR) has updated algorithms for difficult airway management, in which, the place of the intubating laryngeal mask (ILMA) is well defined. Moreover, in the guidelines, the SFAR recommended that the training for the different techniques for difficult intubation should initially be achieved on manikins. However, few data are available for disposable ILMA learning process on manikins. STUDY DESIGN: To compare, on manikin, the learning curves of the disposable and reusable ILMA. MATERIALS AND METHOD: Forty operators (anaesthesiologist, nurse, resident), experienced with conventional tracheal intubation but novice to commercially available ILMAs (Sebac, Pantin, France), underwent videotape learning and manikin training. After randomisation, each participant had to perform 10 timed consecutive tracheal intubations with either reusable or disposable ILMA. The learning curve was built according to the duration of successful procedure. Failure was considered if tracheal intubation could not be achieved or if the procedure lasted more than five minutes. RESULTS: No difference was noted between the two groups in terms of learning curves, number and repartition of the failed attempts during the learning process. CONCLUSION: This study shows that both disposable and reusable ILMA share similar learning process on manikins. Further studies are needed to evaluate the efficiency of the disposable ILMA in the clinical field of difficult intubation.
