Diseases of the circulatory system are the most common cause of death in Brazil. Because the general population is often the first to identify problems related to the circulatory system, it is important that they are trained. However, training is challenging owing to the number of persons to be trained and the maintenance of training.
To assess the delivery of a medical-student led cardiopulmonary resuscitation (CPR) training program and to assess prior knowledge of CPR as well as immediate and delayed retention of CPR training among middle school students.
Two public and two private schools were selected. CPR training consisted of a video class followed by practice on manikins that was supervised by medical students. Multiple choice questionnaires were provided before, immediately after, and at 6 months after CPR training. The questions were related to general knowledge, the sequence of procedures, and the method to administer each component (ventilation, chest compression, and automated external defibrillation). The instructors met in a focus group after the sessions to identify the potential problems faced.
In total, 147 students completed the 6-month follow-up. The public school students had a lower prior knowledge, but this difference disappeared immediately after training. After the 6-month follow-up period, these public school students demonstrated lower retention. The main problem faced was teaching mouth-to-mouth resuscitation.
The method used by medical students to teach middle school students was based on the see-and-practice technique. This method was effective in achieving both immediate and late retention of acquired knowledge. The greater retention of knowledge among private school students may reflect cultural factors.
循环系统疾病是巴西最常见的死亡原因。由于普通人群通常是最先发现与循环系统相关问题的人，因此对他们进行培训非常重要。但是，由于需要培训的人数众多以及培训的维持，培训具有挑战性。
评估医学生主导的心肺复苏术 (CPR) 培训计划的实施情况，并评估中学生对 CPR 的初步了解以及 CPR 培训的即时和延迟保留情况。
选择了两所公立和两所私立学校。CPR 培训包括视频课程，然后由医学生监督使用模型进行练习。在 CPR 培训之前、之后立即以及 6 个月后提供多项选择题问卷。这些问题与一般知识、程序顺序以及每个组件（通气、胸部按压和自动体外除颤器）的管理方法有关。在课程结束后，指导员们在焦点小组中开会，以确定面临的潜在问题。
共有 147 名学生完成了 6 个月的随访。公立学校的学生先验知识较低，但这种差异在培训后立即消失。6 个月随访期后，这些公立学校的学生表现出较低的保留率。面临的主要问题是教授口对口复苏术。
医学生用于教授中学生的方法基于观察和实践技术。这种方法在实现即时和长期保留所学知识方面非常有效。私立学校学生保留知识的能力更强可能反映了文化因素。
