Abstract 215: New Mannequin Made by Recyclable Plastic Bottles for Training Thoracic Compressions at Schools
Introduction: The teaching of Cardiopulmonary Resuscitation (CPR) in schools is already established by the "Kids Save Lives".A low-cost mannequin with the possibility of using recycled material may be a new means of training for children and young people in low-income areas. Objectives: To develop a low-cost mannequin derived from recycled material and evaluate its ability to demonstrate simulations of chest compressions for children and young people. Methods: Development of the model of a low fidelity mannequin made by children in a standard platform based on a plastic bottle (PET) inserted in a T-shirt with other recycled materials such as paper and Styrofoam. The compression simulation test was conducted by a randomized, single-blind study with the inclusion of volunteers at a high school. The children, without previous training in CPR, were randomized to one of the training arms of Laerdal’s Litle Anne mannequin (L) or plastic bottle mannequin (PB). The compression test was performed on a multi-sport court, during 60 minutes, through a video demonstration of CPR with emphasis on chest compressions. The two groups were balanced in age and gender. After the training, all students underwent a test on the Anne Quality Laedal mannequin with two minutes of chest compressions supervised by an instructor (blind to the previous training), that evaluate the frequency of the compressions, correct position of the hands, mean time without compression, total number of compressions and mean depth of compressions. Results: A total of 88 children and young people with a mean age of 14 years of both genders were included. Forty children trained with the L mannequin and 48 with the PB. The variable depth of compression showed differences between the trained groups, where the PB model was 4.1 points higher than the L model (p=0.012) without being able to affirm that there was an effect on the item depth sufficient (p=0.077). Others variables did not present differences between groups. Conclusion: The PB mannequins have very low cost and can be a new model for CPR training in schools. On the compressions ability, only the depth variable was superior in the PB model, perhaps due to the greater similarity of the mannequin to human chest strength.
