急性重症胰腺炎患者死亡时间的日周期分布特征

The diurnal rhythm distribution of the death time of acute severe pancreatitis patients

目的探讨急性重胰腺炎患者死亡时间的日周期分布特征。方法运用χ2检验和圆形分布方法,分析了1980年-2007年间收治的247例ASP患者的死亡时间。结果①所分析的病例中有179例死于夜间,占72.47%,年龄组间差异有显著性,而性别间和两诊疗年代间则否;②全部病例死亡时间的集中趋势为04:12,而夜间死亡病例的集中趋势为03:41,2年龄组间和两诊疗年代间差异有显著性,但性别间差异无显著性;③老龄急性重症胰腺炎患者与老龄慢性呼吸衰竭患者同类资料比较差异无显著性。结论急性重症胰腺炎患者死亡时间确实存在夜间集中趋势,提示我们必须及时地采取相应的诊疗和急救措施才能使患者安度"魔鬼时间"。

Objective To investigate the diurnal rhythm distribution of the death time of acute severe pancreatitis patients. Methods The death time of 247 patients with acute severe pancreatitis during 1980-2007 was analyzed with χ^2-test and circular distribution method.Results ①Of all cases analyzed, 179 （72.47%） died in the nighttime. There was significant difference between aged groups, but no significant difference was found between the sex groups and the treatment-times groups.②The central tendency of the death time of all cases was at 4：12 o＇clock while that of 179 cases who died in the nighttime was at 3：41 o＇clock. There was significant difference between aged groups and the treatment-times groups, but no significant difference was found between the sex groups. ③There was not significant difference between the aged patients with acute severe pancreatitis and the aged patients with chronic respiratory failure. Conclusion There was, indeed, a central tendency in the diurnal periodical distribution of the death time of acute severe pancreatitis patients, suggesting that timely and emergent treatment measures must be taken accordingly to help the patients to survive ＂the devil＇s time.
