Abstract 132: Effects of a 2-hours BLS Course With and Without a Supplementary 7-min Training Video on Resuscitation Performance During Simulated Cardiac Arrest
Background: The 2010 guidelines for cardiopulmonary resuscitation recommend high quality chest compressions without unnecessary interruptions. This emphasizes the importance of new teaching strategies aiming on high quality chest compressions. Objective of the study was to evaluate the effects of a supplementary training video after a 2 hours basic life support (BLS) course on the no-flow fraction and other quality measures in BLS during a 5-minutes simulated resuscitation scenario.
Methods: 163 students of medical professions underwent a 2 hours shortened practical BLS curriculum. Participants were randomized into video and control group. Before and after the course the participants completed a 5-minutes resuscitation scenario with persisting ventricular fibrillation pairwise (scenario 1 + 2) using Resusci Anne Simulator (Laerdal, Stavanger/ Norway). The video group watched a 7-minutes educational video demonstrating optimal sequence of resuscitation tasks and aiming to reduce interruptions in chest compressions. Both groups were evaluated in a third scenario. Primary endpoint was the no-flow fraction; secondary endpoints include pre- and post-shock pause in chest compressions and other quality measures.
Results: Repeated-measures ANOVA revealed a significant decrease of NFF after the BLS course by over 20% (control group from .59 to .36, video group from .61 to .39 (p<.01)).
Analysis also revealed a significant difference between the two groups after video Intervention (p=.011), indicating that the video group again improved their performance whereas control group did not. After the BLS training, the pre-shock pause decreased in both groups (p<.01). After watching the video, the pre-shock pause in the video group decreased from 25 to 20 seconds without reaching statistical significance.
Conclusions: A 7-minutes video intervention with focus on optimal sequence of tasks improves resuscitation skills even after a 2 hours BLS course.
