目的:探讨急性中风病例死亡时间的昼夜节律变化特点和规律。方法:回顾性分析180例急性中风死亡患者死亡时间,利用圆形分布的统计方法计算出死亡高峰时刻和24 h内95%的死亡时间集中时间段。结果:急性中风患者严格统计学意义上的死亡高峰时间是不存在的(P>0.10),相对的死亡高峰时刻为清晨07:24;出血性脑血管病患者死亡高峰时刻为清晨07:48;缺血性脑血管病患者的死亡高峰时刻为清晨05:43。结论:脑血管病患者死亡时间有一定的昼夜节律分布特点,清晨通常为死亡的高峰时段,工作中应加强夜间和凌晨患者的管理和监测,对减少病死率有积极意义。
Objective: To investigate the characteristics and regularity of circadian rhythm of death in acute stroke. Methods: A retrospective analysis of 180 patients died of acute stroke death time, the use of circular distribution of statistical methods to calculate the peak time of death and 95% of 24 h within the focus of the time of death. Results: The peak time of death was not statistically significant in patients with acute stroke (P> 0.10), the relative peak of death was at 07:24 in the morning and the peak of death in patients with hemorrhagic cerebrovascular disease was at 07:48 in the morning. The peak time of death in patients with ischemic cerebrovascular disease is 05:43 in the morning. Conclusion: The death time of patients with cerebrovascular disease has some characteristics of circadian rhythm distribution. Early morning is usually the peak period of death. The management and monitoring of patients at night and in the early morning should be strengthened in the work, which is of great significance to reduce the mortality.
