急诊院前猝死事件的发生特点

The analyses of the features of pre-hospital sudden death

目的：系统分析院前猝死事件的发生特点，了解院前猝死事件的发生规律，以便更好地对于院前猝死事件、特别是心脏性猝死进行有效的救治、降低病死率。方法和结果:分析我院 1973～1999 年院前急诊救治病例 1030 例，其中院前发生猝死病例 106 例；猝死的高发年龄段有两个：一个为 66～75 岁年龄段（为27.3％）,另一为46～55年龄段（非退休年龄，为22.6%）；发生猝死病例中，既往有明确心血管病史的病例68例（占64.2％），不明原因23例（占21.6％），其他原因15例（占14.2%）；引发猝死的直接原因为：室速、室颤（构成比 55.0%）心源性休克(16.7%)；结论：院前猝死事件，是目前需要院前急诊救治的主要急危重症之一，而其中以急性心血管事件所致的猝死的救治更为重要。对于已有心血管病基础的患者应注意其发生猝死的高度危险性，同时应注意低年龄组人群猝死的发生。

Objective:systemically analysis the features of the pre-hospital sudden deathevents(SDE), especially the features of cardiac sudden death, for further elucidating the regularities of the SDEs, and for further decreasing the mortality of SDEs. Methods: totally 1030 pre hospital emergent cases be collected from 1973～1999, were analyses systemically. Results:the total SDEs are 106 cases; the cases who had basic cardiovascular diseases are 68,in which there are 89.6% have coronary heart diseases(CHD) AMI or OMI with re infarction. It should be highly noticed that, there are two peak SDEs age stages: the first is 46-55 year old stage(non, retaired age stage,ratio:22.6%), and the second stage is 66. 75 years old(ratio:27.3%)Conclusion: The pre-hospital SDEs, now is one of the most needed to be treated emergent cases. For those had the history of cardiovascular diseases, it should be highly noticed that the high possibility of sudden death, especially those have basic coronary cardiac events
