Abstrakt:	Objectives: To assess the ability of schoolchildren to use a automated external defibrillator (AED) to provide an effective shock and their retention of the skill 1 month after a training exercise supported by audiovisual materials. Material and Methods: Quasi-experimental controlled study in 205 initially untrained schoolchildren aged 6 to 16 years old. SAEDs were used to apply shocks to manikins. The students took a baseline test (T0) of skill, and were then randomized to an experimental or control group in the first phase (T1). The experimental group watched a training video, and both groups were then retested. The children were tested in simulations again 1 month later (T2). Results: A total of 196 students completed all 3 phases. Ninety-six (95.0%) of the secondary school students and 54 (56.8%) of the primary schoolchildren were able to explain what a SAED is. Twenty of the secondary school students (19.8%) and 8 of the primary schoolchildren (8.4%) said they knew how to use one. At T0, 78 participants (39.8%) were able to simulate an effective shock. At T1, 36 controls (34.9%) and 56 experimental-group children (60.2%) achieved an effective shock (P< .001). At T2, 53 controls (51.4%) and 61 experimental-group children (65.6%) gave effective shocks (P=.045). All the students completed the tests in 120 seconds. Their average times decreased with each test. The secondary school students achieved better results. Conclusion: Previously untrained secondary school students know what a AED is and half of them can manage to use one in simulations. Brief narrative, audiovisual instruction improves students' skill in managing a SAED and helps them retain what they learned for later use.
