Automated external defibrillation by very young, untrained children.
For patients with sudden cardiac death (SCD), the time interval to defibrillation is the main determinant of survival. As such, the American Heart Association has attempted to promote public-access defibrillation (PAD). Previous studies have shown that automated external defibrillators (AEDs) can be used successfully by untrained adults.


OBJECTIVE
To determine whether very young, untrained children could use AEDs.


METHODS
Third-grade students from an elementary school participated in this study representing a convenience sample of volunteers. They were given no formal training, but were shown how to peel off the backing from the electrode pads, like a sticker. Students were then given a mock code situation using a training manikin. The time to delivery of first shock was recorded. Students were then trained during a 2-minute review of the process, one on one with an instructor, and the study was then repeated. Data were analyzed using a paired Student's t-test comparing pre- and post-training.


RESULTS
Thirty-one children participated in the study, with a median age of 9 years. For untrained children, the mean time for delivery of the first shock was 59.3 +/- 13.6 seconds, 95% CI = 54.3 to 64.3. Following training, the mean time for delivery of the first shock was 35.2 +/- 6.0 seconds, 95% CI = 33.0 to 37.4, p = 0.001.


CONCLUSIONS
Although this study suggests that even very young, untrained children can successfully perform automated external defibrillation, training does significantly decrease the time to delivery of first shock.
