概括
公共出血控制套件可以拯救生命. 根据商场模拟,在公共场所放置这些装有自动外部除器 (AED) 的套件可以最大限度地提高大规模伤亡事件中的生存率.
科学领域:
- 紧急医疗 紧急医疗
- 公共卫生 公共卫生
- 创伤外科 手术 创伤外科
背景情况:
- 公共获取出血控制 (BAC) 措施可以显著减少与创伤相关的死亡事故.
- 在公共场所战略性地放置出血控制套件 (BCKs) 对于能够及时介入旁观者至关重要.
- 大规模伤亡事件 (MCI) 需要有效的公共安全策略和立即的医疗反应.
研究的目的:
- 调查不同公共出血控制套件放置策略对模拟大规模伤亡事件中的伤亡者生存的影响.
- 为了比较BCK与自动外部除器 (AED) 联合定位的有效性与其他分布模型.
主要方法:
- 开发了一个计算机模拟商场炸弹爆炸的模拟.
- 参数包括伤亡人数,公众愿意提供帮助,以及受伤类型,这些都是由证据和专家意见来决定的.
- 评估了四种BCK放置策略:与AED同处 (90秒间隔),分散 (10个位置) 和1个或2个出口附近.
主要成果:
- 在90秒的步行间隔内将BCK与AED放在同一位置,产生了最高数量的幸存受害者 (18.2).
- 在整个购物中心均分散10个套件,导致存活率略低 (18.0).
- 在一个或两个主要出口放置套件导致幸存者最少 (15.9和16.1).
结论:
- 在90秒的步行间隔内与AED同时放置出血控制套件是改善模拟大规模伤亡事件中伤亡结果的最佳策略.
- 战略布置,而不仅仅是BCK的可用性,对于最大限度地提高公共空间的生存率至关重要.
- 这一发现支持将出血控制资源整合到现有的公共安全基础设施中,例如安装AED.
