¿Pueden los escolares aprender el DESA con materiales baratos? DIY-AED, un dispositivo adaptado de bajo coste

Abstract

The Kids Save Lives statement promotes the teaching of BLS content in schools (Schroeder et al). Training projects within the declaration have highlighted the importance of implementing strategies with low-cost materials (Nakagawa et al). Objective: To describe the AED use skills of 10-11 YEAR primary school students after training with low-cost adapted teaching material (DIY-AED). Methods: A quasi-experimental simulation study was carried out with a total sample of 38 schoolchildren (58% male and 21% with previous training in some first aid content). Three nurses gave the students a brief 20-minute session of explanation-demonstration-simulation of AED using the DIY-AED. The DIYAED is a low-cost tool designed to enable school children to manipulate an AED with simple materials. The approximate cost of each DIY-AED was 5€. All participants had a DIY-AED at their disposal during the session and were able to perform a complete AED sequence. The simulation assessment was performed with a Laerdal manikin and a training AED. Results: 90% (34/38) of the participants demonstrated that they were able to use the AED autonomously. The remaining four participants showed some difficulty (1. not being able to use the AED; 2. not performing a safe shock; 3. making a mistake in the order of the sequence; 4. needing help from the teleoperator to use the AED). 84% of the participants placed the electrodes in the recommended location. 97% delivered a safe shock to the victim. 29% of participants did not restart CPR after the shock. The mean time from AED arrival to shock delivery was 109±19 seconds; 95% CI (103-116) seconds. Conclusion: DIY-AED has proven to be a useful tool for the acquisition of AED skills using accessible, inexpensive and/or recyclable materials. All participants were able to perform simulation without the need for AED training, so it appears to be an efficient tool for training in schools.
