Avaliação de conhecimentos de estudantes do ensino médio acerca da cadeia de sobrevivência em suporte básico de vida antes e após treinamento teórico-prático

Abstract

Object: Evaluate the knowledge of high school students about the links of the survival chain and the understanding of Basic Life Support (BLS). Method: Study conducted in a public school with high school students. The following steps were followed: 1) Application of a questionnaire, with the objective of ascertaining the students’ previous knowledge on the subject; 2) Presentation of a dialogued conference on the survival chain in cardiac arrest situations; 3) Development of practical skills with students on how to act in a PCR situation, following the survival chain; 4) Application of the same questionnaire in order to ascertain students’ knowledge after the development of the activity. Results: the average of correct answers when comparing the pre and post-test considering questions regarding the survival chain, prehospital care by SAMU, cardiopulmonary resuscitation and cardiac arrest showed a significant difference (Wilcoxon test p <0.001). Conclusion: There was a significant acquisition of theoretical knowledge by high school students about the survival chain in Basic Life Support, after the theoretical and practical intervention, inferring that these university extension actions contribute to educating the population and may result in reduced mortality in cases of CRP in an out-of-hospital setting.
