目的：探讨护理干预应用于低分子肝素钙预防下肢骨折术后深静脉血栓形成的临床疗效。方法选择2014年2月至2015年2月医院收治的下肢骨折手术患者120例，根据随机数字表法分为对照组（常规护理）和观察组（护理干预），各60例，术后均给予低分子肝素钙治疗。观察并比较两组深静脉血栓形成、下肢肿痛的发生率，治疗后血液流变学、凝血酶原时间（PT）、D-二聚体变化情况，以及护理满意度。结果与对照组相比，观察组术后深静脉血栓形成、下肢肿痛的发生率均显著降低（ P﹤0.05）；全血高切黏度、全血中切黏度、全血低切黏度、红细胞聚集指数、D-二聚体水平均明显降低，PT明显增高（ P﹤0.05）；护理满意度明显改善（ P﹤0.05）。结论低分子肝素钙预防术后深静脉血栓形成期间，护理干预能明显改善下肢骨折手术患者血流的高凝、高黏度状态，提升护理满意度。%Objective To study the clinical efficacy of nursing intervention of nursing intervention on deep venous thrombosis after lower limb fractures treatment by low molecular heparin calcium. Methods 120 operation patients with lower limb fractures in the hospital during February 2014 to February 2015 treated by low molecular heparin calcium were divided into the control group ( routine nursing ) and the observation group ( nursing intervention ) according to the random number method, 60 cases in each group. The incidence of deep venous thrombosis and lower limb swelling and pain, the changes of blood rheology, prothrombin time ( PT ) , D-dimer, and the nursing satisfaction degree in the two groups were observed and compared. Results Compared with the control group, the incidence of deep venous thrombosis and lower limb swelling and pain were significantly reduced in the observa-tion group ( P ﹤ 0. 05 ); compared with the control group, the levels of whole blood high shear viscosity, whole blood cut viscosity, whole blood low cut viscosity, erythrocyte aggregation index and D-dimer were significantly decreased and the PT was obviously in-creased after nursing in the observation group ( P ﹤ 0. 05 );compared with the control group, the satisfaction degree for nursing service was significantly improved in the observation group ( P ﹤ 0. 05 ) . Conclusion Low molecular heparin calcium with effective nursing intervention in the prevention from deep venous thrombosis can significantly improve the high coagulation and viscosity state of blood flow and increase the nursing satisfaction degree.
