本文对 52例肺栓塞患者治疗前后纤维蛋白原和D 二聚体进行测定 ,发现治疗有效者纤维蛋白原有明显下降 (P <0 .0 5) ,无效者则有上升趋势 ,而D 二聚体在治疗 2 4h后下降 ,其中有效者下降明显 (P <0 .0 5) ,结果表明 ,纤维蛋白原和D 二聚体的变化对肺栓塞疗效判定有一定临床意义 In this paper, 52 patients with pulmonary embolism before and after treatment of fibrinogen and D dimer determination found that the effective treatment of fibrinogen was significantly decreased (P <0. 05), the ineffective is an upward trend, and D dimerization Body in the treatment of 24 h after the decline, in which the effective decreased significantly (P <0. 05), the results show that changes in fibrinogen and D dimer determine the efficacy of pulmonary embolism has some clinical significance
