Epidemiology of out of hospital cardiac arrest in school children and the role of school ECG screening

假设：我们假设，在国家一级，在学校进行公共除颤（PAD）与此类学生发生院外心源性心脏骤停（OHCA）后结局的改善相关。 方法：分析2005- 2009年日本Utstein登记和全国学龄儿童调查数据。 结果如下：在所有合格患者中，最初被旁观者电击的患者比例和OHCA后神经系统结局良好的患者比例增加。除颤时间与OHCA后良好的神经功能结局独立相关。 50%的患者在学校有OHCA，这与运动期间的事件有关。 学校的OHCA与良好的神经学结局相关。 结论：在日本全国范围内，小学和中学学生在学校接受PAD与OHCA后良好的神经功能结局相关。

Hypothesis: We hypothesized that public-access defibrillation (PAD) at school was associated with the improved outcome after out-of-hospital cardiac arrest (OHCA) of cardiac origin (OHCA) in such students at the national level. Methods: We analyzed Japanese Utstein registry and nation-wide survey data of school children during 2005-9. Results: The proportion of patients initially shocked by a bystander among total eligible patients and the proportion of patients with a favorable neurological outcome after OHCA increased. The collapse to defibrillation time was independently associated with a favorable neurological outcome after OHCA. 50% of patients had OHCA at school, which was associated with the event during exercise. OHCA at school was associated with a favorable neurological outcome. Conclusions:PAD at school is associated with a favorable neurological outcome after OHCA in elementary and middle school students at the national level in Japan.
