蛛网膜下腔出血患者再出血的危险因素

目的：探讨蛛网膜下腔出血患者再出血的危险因素。方法：对168例住院蛛网膜下腔出血患者随访观察6个月，出现再出血者40例，对再出血者有关危险因素水平与对照组无再出血的128例蛛网膜下腔出血患者的有关危险因素水平进行比较。结果：168例蛛网膜下腔出血患者发生再出血40例，再出血率23．8％；病例组在发病年龄〉60岁、高血压、动脉瘤、入院时间〉24h、饮酒等危险因素均高于对照组，特别是动脉瘤、高血压、饮酒；而吸烟、性别、糖尿病、高血脂症两组间无明显统计学差异。结论：发病年龄〉60岁、高血压、动脉瘤、未手术治疗、入院时间〉24h及饮酒是蛛网膜下腔出血患者再出血的危险因素。

Study on the risk factors of rebleeding in subarachnoid hemorrhage

Objective To evaluate the risk factors of rebleeding in subarachnoid hemorrhage patients.Methods One hundred and sixty-eight patients who survived the subarachnoid hemorrhage were followed up for 6 months after the bleeding,which included 40 cases of rebleeding,128 cases of nonrebleeding.The risk factors were compared between the two groups.Results In the rebleeding patients,more patients had the risk factors as being over 60 years,hypertension,aneurysm,admission over 24 hours after the first attack,diabetes and drinking alcohol in the rebleeding patients,with a significant difference compared with nonrebleeding patients(P<0.01).There was no significant difference in the other risk factors,as smoking,sex,heart disease and hyperlipidemia between two groups(P>0.05).Conclusion Being over 60 years old,hypertension,aneurysm,admission over 24 hours after the first attack,diabetes and drinking alcohol were the risk factors in rebleeding insubarachnoid hemorrhage.
