[Abstract] ObjectiveTo observe the level of plasma fibrinogen(FIB) at acute pha se in medium to large spontaneous supratentorial intracerebral haemorrhages(ICH)and analyze the impact factors associated with FIB.Methods153 patients withspontaneous supratentorial intracerebral haemorrhages were included in this stud y. We measured their plasma FIB at next morning and obtained the other clinicaldata associated with the prognosis of ICH routinely. According to the higher li mit of the plasma FIB level, we defined plasma FIB>4.00g /L as the elevated leve l. Univariate and multiple logistic regression were used respectively to analyzethe correlativity of the elevated plasma FIB with related 20 factors.Results The percentage of supratentorial ICH patients with plasma FIB>4.0g/L was 36.5% a nd plasma FIB≤4.00g/L was 63.52%. The independent impact factors of plasma FIBwere sex, scores of National Institutes of Health Stroke Scale(NIHSS), and plate let(PLT). ( OR=3.916, 95%CI 1.612~9.516, OR=2.622, 95%CI 1.560~4.408, OR=1.007 , 95%CI 1.001~1.012,respectively).Conclusions The independent impact factors of p lasma FIB were sex, scores of National Institutes of Health Stroke Scale, and pl atelet at acute phase in medium to large spontaneous supratentorial intracerebra l haemorrhages.

据报道,脑出血时血浆纤维蛋白原(FIB)浓度等血液流变学指标有异常改变,FIB≤4.0g/L 是中大量自发性幕上脑出血预后良好的独立预测因素[1]。本文分析153例中大量自 发性幕上脑出血患者在发病24小时内的FIB及其临床资料,探 讨影响FIB水平的有关因素,现报道如下。
1 资料与方法
1.1 一般资料:选择2007年4月至2008年4月,温州市、舟山市人民医院的神经内科,中到 大量自发性幕上脑出血住院患者153例。均符合1995年全国脑血管病会议制定的诊断标准, 急性起病,排除非血管性病因。脑CT检查确诊为脑出血,位于幕上,首次脑CT扫描出血量≥ 20ml,脑出血量按多田氏公式(π/6×长×宽×层厚)来计算,排除蛛网膜下腔出血,及其他 非卒中颅内疾病。153例中,男101例,女52例,年龄30~84(59.0±11.8)岁。患者基本临床特征:见表1。入院时患者的FIB水平范围是1.70~7.06g/L,呈近似正态分布,其 均数为(3.83±1.00)g/L。
1.2 方法:所有患者均完成统一的脑卒中入院登记表,全面收集患者的临床特征、一般情 况、既往史、临床体征和FIB等资料。在入院次晨测FIB,并全面搜集可能与FIB相关 的其他临床指标;所有测定均在相关医院检验科进行。患者均在入院后次晨采取静脉血注入 真空抗凝管中(3.2%构除酸钠溶液)送检。检测仪器采用法国公司Stago 公司STA_compact,STA_R全自动血凝仪。正常参考值为2.0~4.0g/L。FIB水平的分界值根 据FIB水平正常参考值高限确定,FIB>4.00g/L定义为高FBI水平,将年龄、性别、入院第一 次血压收缩压、舒张压、出血部位:皮层、深部、脑室出血或破入脑室、中风或TIA、高血 压、糖尿病、高血脂、吸烟、酗酒、入院GCS评分(Glasgow Coma Scale)、入院美国国立卫 生院脑卒中量表评分(NIHSS, National Institutes of Health Stroke Scale)、低密度脂 蛋白(LDL, Low density lipoprotein)、甘油三酯(TG,Triglyceride)、血小板(PLT,Pl atelet)、空腹血糖、入院时随机血糖,可能影响FIB的20个因素作为自变量,FIB水平作为 应变量作单因素和多因素Logistic回归分析。
1.3 统计学方法:使用SPSS12.0软件包对资料数据进行统计分析。以单因素Logistic回 归分析,P≤0.10时该因素可能与预后有关,可进入多因素Logistic逐步回归分析。
2 结果
2.1 影响FIB水平的单因素分析:将可能影响入院时FIB水平的20个因素行单因素Logistic回归分析,见表2。结果显示:性别 、吸烟、入院GCS评分、入院NIHSS评分、PTL、6个变量的P值≤0.10,可以进入多因素 Logistic回归分析。, 百拇医药(戴方瑜 韩钊 臧秋玲 王苹莉 叶祖森)
