骨折病人血管完整性遭到破坏,凝血系统被激活,从而降解纤维蛋白原,形成纤维蛋白,纤溶系统相继被激活,形成血浆纤维蛋白原降解产物(fibrin/fibrinogen degradation products,FDP)碎片与D-二聚体(D-dimer,DD),因此,凝血指标处于动态变化之中[1]。同时,骨折病人恢复时间较长,病人需长期卧床及制动,极易诱发深静脉血栓(deep vein thrombosis, DVT)、肺栓塞等并发症。DD和FDP是评价凝血功能的重要指标,是骨科用来判断病人凝血功能是否正常、是否发生血栓的常用指标。临床研究[2]指出,通过观察凝血指标变化,采取针对性治疗措施,可有效预防DVT。本研究对骨折病人凝血指标和DD、FDP水平进行检测,分析其临床价值。现作报道。

摘要:
目的探讨凝血指标和D-二聚体(DD)及血浆纤维蛋白原降解产物(FDP)水平检测对骨折病人的临床意义。 方法选取骨折病人57例作为观察组,同期健康体检者68名作为对照组,比较2组凝血酶原时间(PT)、活化部分凝血酶原时间(APTT)、凝血酶时间(TT)、纤维蛋白原(Fg)和DD、FDP水平,并比较观察组不同类型骨折病人Fg、DD、FDP阳性率,以及发生深静脉血栓(DVT)与未发生DVT病人的Fg、DD、FDP水平。 结果观察组Fg、DD、FDP水平均明显高于对照组(P < 0.01),TT低于对照组(P < 0.05),2组PT和APTT差异均无统计学意义(P>0.05)。观察组中不同类型骨折病人Fg、DD阳性率差异均无统计学意义(P>0.05),FDP阳性率差异有统计学意义(P < 0.05)。术前1 d,观察组中发生DVT与未发生DVT病人的Fg、DD、FDP水平差异无统计学意义(P>0.05);术后7 d,发生DVT病人Fg、DD和FDP水平均明显高于未发生DVT病人(P < 0.01),且发生DVT病人Fg、DD、FDP水平均较术前1 d明显升高(P < 0.01)。 结论凝血指标和DD、FDP水平可有效反映骨折病人凝血功能,灵敏度较高,对预防病人DVT形成具有一定的指导价值。 -

Abstract:ObjectiveTo explore the clinical significance of the coagulation parameters, D-dimer (DD) and plasma fibrinogen degradation product(FDP) levels in patients with fractures. MethodsA total of 57 fracture patients and 68 healthy people were divided into the observation group and control group, respectively.The prothrombin time(PT), activated partial prothrombin time(APTT) and thrombin time(TT), and levels of fibrinogen(Fg), DD and FDP were compared between two groups.Among the patients in observation group with different types of fractures, the positive rates of Fg, DD and FDP, levels of Fg, DD and FDP in patients with and without deep vein thrombosis(DVT) were compared. ResultsThe levels of Fg, DD and FDP in observation group were significantly higher than those in control group(P < 0.01), the level of TT in observation group was lower than that in control group(P < 0.05), and the differences of the level of PT and APTT between two groups were not statistically significant(P>0.05).The differences of the positive rates of Fg and DD in observation group with different types fracture were not statistically significant(P>0.05), and the difference of the positive rate of FDP in observation group with different types fracture was statistically significant(P < 0.05).Before 1 day of operation, the differences of the levels of Fg, DD and FDP in observation group between patients with and without DVT were not statistically significant(P>0.05).After 7 days of operation, the levels of Fg, DD and FDP in patients with DVT were significantly higher than those in patients without DVT(P < 0.01), and the levels of Fg, DD and FDP in patients with DVT significantly increased compared with before 1 day of operation(P < 0.01). ConclusionsCoagulation index, DD, FDP can effectively reflect the coagulation function of fracture patients, its sensitivity is high, and it has certain guiding value to prevent the DVT formation in patients. -
