Laryngeal tube and intubating laryngeal mask insertion in a manikin by first-responder trainees after a short video-clip demonstration

Prehosp Disaster Med. 2009 Jan-Feb;24(1):63-6. doi: 10.1017/s1049023x00006555.


Introduction: This study was performed in the Finnish Defense Forces to assess the potential applicability and value of short video clips as educational material to teach advanced airway management and as the first means of introducing the use of a laryngeal tube (LT) or an intubating laryngeal mask (ILMA) to inexperienced, military, first-responder trainees with no prior hands-on experience.

Methods: The 60 non-commissioned medical officers participating in this study were randomly assigned into one of two groups: the LT- and the ILMA-group. After viewing the video clips, the trainees were required to perform 10 consecutive, successful insertions of the given instrument into a manikin. The number and duration of the attempts required prior to the 10 consecutive successful insertions were measured.

Results: The goal of 10 consecutive successful insertions was attained by all 30 subjects in the LT-group, and by 27 of 29 subjects in the ILMA-group with a maximum of 30 attempts. Improvement in the ease and speed of insertion was evident between the first and last consecutive insertions in both groups.

Conclusions: "Satisfactory" to "good" skill levels are achieved with the applied video-clip demonstration method, even in inexperienced first-responder trainees lacking previous hands on experience.
