[目的]探讨急性颅脑创伤患者血浆凝血因子Ⅶ(FⅦ)活性变化及其与凝血功能的相关性.[方法]选取2014年3月至2016年3月本院收治的急性颅脑创伤患者92例作为观察组,同时选择同期在本院体检健康的92例健康志愿者作为对照组,检测两组血浆FⅦ活性值,并检测活化部分凝血活酶时间(AFFF)、血小板(PLT)、D-二聚体、纤维蛋白原(FIB)、血红蛋白(Hb)、血乳酸(Lac)等相关凝血指标,计算国际标准化比值(INR),并检测颅内压(ICP).比较观察组和对照组血浆FⅦ活性及其与凝血功能指标的相关性.[结果]观察组血浆FⅦ活性值为(91.45±32.10)%,对照组为(97.20±16.03)%,两组比较差异无统计学意义(t=-1.537,P>0.05).血浆FⅦ活性低患者INR、APTT、Lac显著高于血浆FⅦ活性高的患者,血浆FIB水平显著低于血浆FⅦ活性高者,差异均具有统计学意义(均P<0.05).观察组伴凝血功能异常患者共计35例,其血浆FⅦ活性为(86.70±28.84)%,观察组不伴凝血功能异常患者57例,其血浆FⅦ活性为(97.83±30.16)%,两组比较差异具有统计学意义(t=-2.176,P0.05).INR,APTT and Lac were significantly higher than that of plasma F activity in patients with high plasma activity FⅦ.The plasma FIB level was significantly lower than that of plasma FⅦ high activity,the differences were statistically significant (P<0.05).abnormal coagulation function in patients of the observation group counted a total of 35 cases,the plasma activity of FⅦ was (86.70±28.84)%,57 patients was accompanied with coagulation dysfunction in the observation group,The plasma activity of FⅦ was (97.83±30.16)%,there were significant differences between the two groups (t=-2.176,P<0.05).[Conclusion]Plasma activity FⅦ in patients with acute craniocerebral trauma is related to coagulation function,Plasma activities FⅦ in patients with abnormal coagulation function decreased,which is worthy of further clinical research.
