脑出血首次血肿量与首次平均血压及其预后的相关性分析

Correlation Analysis of Initial Volume of Hematoma Initial Mean Blood Pressure and Prognosis of Patients with Cerebral Hemorrhage

目的：脑出血首次血肿量（IVH）与首次平均血压（IMBP）及其预后的相关性进行研究，并提出了脑出血易感性假说即P＝K■。方法：1．不同出血部位的年龄、IVH、IMBP进行比较。2．同一出血部位存活组与死亡组的IVH进行比较．3．IVH与年龄、IMBP、预后进行相关性分析。4．统计学处理：评价用X±SD；t检验；相关性分析用直线回归。结果：1．基底节、皮质下出血与丘脑比较显示：IVH大（P＜0．05）。2．基底节与皮质下出血比较：平均年龄小（P＜0．05）；IMBP高（P＜0．05）。3．死亡组的击底节、皮质下出血的IVH大于存活组（P＜0．001）。4．相关性分析：IVH与IMBP相关性：基底节呈正相关；基底节及皮质下均显示相关。结论：基底节出血的IMBP及病死率、皮质下出血的病死率随IVH的增加而增高。

Objective The correlation was studied between initial volume of hematoma (IVH)and initial mean bIood pressure(IMBP) and prognosis in patients with cerebral hemor-rhage. Hypothesis was put forward of predisposion in cerebral hemorrhage.Methods: 1. Comparison with age,IVH,IMBP in different hemorrhagic location. 2. Comparison with IVH between un fatal and fatal groups in the same Iocation 3. Correlation be-tween IVH and age,IMBP,prognosis. 4. Statistical Methods:Values were expressed as mean ±SD; Student's t test ;linear regression was used in correlation analysis. Results: 1. Comparing basal ganglionic and subcortical to thalamus:IVH larger (P<0. 05) 2. Comparing basal ganglionic to subcortical: mean age younger(P<0. 05) ; IMBP higher (P>0.05 ) 3. The IVHsof basal ganglionic and subcortical in fatal group were respectively larger than that in unfatal. 4. Correlation Analysis:Correlation between IVH and IMBP in basal ganlionic was positive lcorrelation in subcortical. Correlation between IVH and fatality rate in basal gangilonic and subcortical was postive. Conclusion:The IMBP and fatality rate in basal ganglionic, and fatalilty rate in subcortical,increased with its IVH.
