急诊老年危重患者凝血纤溶指标的变化及与病情严重程度的关系

目的 通过监测急诊老年危重患者凝血、抗凝、纤溶等指标,观察这些指标的变化及是否与病情严重程度相关.方法 选择年龄≥60岁,符合系统性炎症反应综合征(SIRS)诊断标准且急性生理和慢性健康状况Ⅱ(APACHE Ⅱ)评分≥10分的危重患者67例,24 h内采静脉血进行凝血检测:部分凝血活酶活化时间(APTT)、凝血酶原时间(PT)、凝血酶时间(TT)、D-二聚体(D-D)、纤维蛋白原(Fib)、抗凝血酶-Ⅲ(AT-Ⅲ)、蛋白C(PC)、纤溶酶原激活物抑制物1(PAI-1),并行APACHE Ⅱ评分.按照生存情况分为存活组(43例)和死亡组(24例),按照老年多器官功能不全综合征(MODSE)诊断标准分为MODSE组(30例)和非MODSE组(37例).结果 MODSE组与非MODSE组APACHE Ⅱ评分(25.83±1.19)分比(18.11±0.73)分]及存活组与死亡组APACHE Ⅱ评分(18.81±0.72)分比(26.50±1.42)分]比较差异均有统计学意义(P<0.01).与非MODSE组及存活组比较,MODSE组及死亡组PT延长,D-D显著升高,AT-Ⅲ、PC活性显著下降(P<0.05).PT、D-D、PAI-1与APACHE Ⅱ评分呈正相关(相关系数分别为0.328、0.308、0.335,P<0.05);AT-Ⅲ、PC与APACHEⅡ评分呈负相关(相关系数分别为-0.469、-0.559,P<0.01).结论 急诊老年危重患者存在凝血、抗凝、纤溶等指标的紊乱现象,且紊乱程度与疾病的严重程度相关,PT延长、D-D升高以及PC、AT-Ⅲ下降,提示病情严重及预后不良.

Relationship between abnormality of coagulation-fibrinolysis system and prognosis of elderly critical patients in emergency department

Objective To investigate the variation of biomarker of coagulation, anti-coagulation, fibrinolysis in elderly critical patients and find out whether they are related to the disease severity. Methods Sixty-seven patients were no less than 60 years old. Eligible criteria: coincidence with the diagnostic criteria of systemic inflammatory response syndrome (SIRS) and APACHE Ⅱ score was no less than 10 scores. Blood sample was drawn from the venous for the test of biomarker (APTT, PT, TT, D-D, Fib, AT-Ⅲ , PC, PAI-1). According to the existent status,all the patients were divided into two groups:survival group (43 cases) and death group(24 cases) ,meanwhile,according to the diagnostic criteria of MODSE,all the patients were divided into MODSE group (30 cases) and non-MODSE group (37 cases). Results There were significant differences in APACHE Ⅱ score between MODSE group and non-MODSE group, survival group and death group (25.83 ± 1.19) scores vs(18.1±20.73) scores and(18.81±0.72) scores vs(26.50 ± 1.42) scores](P <0.01). The PT and D-D in MODSE group anti death group were higher than those in non-MODSE group and survival group, the differences were significant (P <0.05),while the activity of AT-Ⅲand PC in MODSE group and death group were lower than those in non-MODSE group and survival group, the differences were significant (P <0.05). The PT,D-D and PAI-1 were positively correlated to APACHE Ⅱ score (related coefficients were 0.328, 0.308, 0.335,P <0.05). The AT-Ⅲ and PC were negatively correlated to APACHE Ⅱ score (related coefficients were -0.469, -0.559,P <0.01). Conclusions The abnormality of eoagnlation-fibfinolysis system exists in elderly critical patients. The extended PT, elevated D-D and PAI-1 ,descended PC and AT-Ⅲ are the hints of disease severity and poor prognosis.
