摘要 目的观察单纯性颅脑损伤患者的凝血功能改变与伤情和预后的关系。方法本组112例患者入院时抽取肘静脉血检查凝血常规指标[包括凝血酶原时间(PT)、活化部分凝血活酶时间(APTT)、凝血酶时间(TT)和纤维蛋白原(FBG)]及D-二聚体。按照患者伤情和预后不同对比凝血指标差异。结果(1)根据GCS评分分组,TT在GCS≤5分组比GCS6~8分(P<0.05)、GCS9~12分(P<0.001)两组都高,FBG在GCS≤5分组较后两组降低(P<0.001);(2)根据GOS评分分组,GOS1分组TT值比GOS2、3、4、5分组延长(P<0.01),FBG在GOS1分组较GOS2、3、4、5分组明显降低(P<0.001);(3)有继发性颅内血肿患者比无继发性颅内血肿患者的PT、APTT值延长(P<0.05),Fbg降低(P<0.05);(4)存在外伤性脑梗死比无外伤性脑梗死患者的PT、APTT值缩短,Fbg值降低(P<0.001);(5)D-二聚体:GCS评分越低,D-二聚体阳性率(>0.5μg/ml)越高(P<0.001),GOS评分预后不良(1~3分)D-二聚体阳性率比预后良好(4~5分)组高(P<0.001),有继发性血肿者D-二聚体阳性率比无继发性血肿者高(P<0.001);有外伤性脑梗死者D-二聚体阳性率比无外伤性脑梗死者低(P<0.01)。结论颅脑损伤后患者存在凝血异常,这种凝血异常与患者的伤情严重程度有关,也与伤后并发症和患者预后有相关性,D-二聚体比凝血常规项目更能敏感地反应出这种凝血功能改变。
