    【摘要】目的 研究不同剂量肝素在重度慢阻肺病人静脉留置针的封管效果。方法 300例重度慢阻肺病人随机分为对照组实验组,各150例,在每次治疗结束后均用3mL肝素盐水正压封管,浓度分别为62.5 U/mL、125 U/mL。观察并比较2组病人堵管及出血发生情况。结果 肝素封管液堵塞的发生率实验组与对照组比较差异有统计学意义 (P<0.01);实验组与对照组在发生出血情况上差异无统计学意义(P>0.05)。结论 重度慢阻肺病人静脉留置针使用3 mL肝素盐水(125 U/mL)封管既可减少堵管发生又安全。

    【Abstract】ObjectiveTo evaluate the different dose heparin in the closure of the superficial venous catheter in patients with severe chronic obstructive pulmonary disease. Methods 300 patients with severe chronic obstructive pulmonary disease with superficial vein indwelling needle were selected and randomly divided into two groups, each group 150 cases. For the observation group ,0.9% sodium chloride injection containing heparin sodium (heparin sodium 125u/ml) was adopted to seal the tube,while for the control group, sodium chloride injection containing heparin sodium (heparin sodium 62.5u/ml) was adopted.The sealing effects of the two methods were compared.. Results The demographics did not differ between the two groups.The transfusion unobstructed conditions of patients of test group were much better than that of the control group cases.Conclusion Sealing tube with 3ml heparin dilution (62.5u/ml) is superior to heparin sodium (125u/ml) in patients with severe chronic obstructive pulmonary disease. ......
