摘要:
比较使用生理盐水、62.5 U/mL肝素液、83.3 U/mL肝素液进行静脉留置针封管的封管效果。将150例患者按抛硬币法分为3组,A组采用生理盐水 5 mL、B组采用62.5 U/mL肝素液3 mL、C组采用83.3 U/mL肝素液3 mL进行封管,记录3组患者留置针留置时间、堵管例数及针眼出血情况。留置时间分别是A组2 d、B组2.3 d、C组3.5 d,两两比较均有显著性差异 (P<0.05);A组堵管率最高,C组堵管率最低。凝血机理正常的患者应用83.3 U/mL肝素液3 mL进行推-停-推的脉冲式冲管加正压封管能有效延长留置时间,降低堵管率。

Abstract:
To investigate the effects of normal saline,62.5 U/mL heparin and 83.3 U/mL heparin in the sealing of superficial vein indwelling needle.Divided 150 patients with superficial vein indwelling needle randomly into three groups: A,B and C,then sealed the tube of A,B and C with normal saline,62.5 U/mL heparin and 83.3 U/mL heparin respectively, and observed the indwelling needle time and the number of tube blockage.The time of indwelling in group A was 2 d, in group B was 2.3 d,in group C was 3.5 d;there were significantly differents among the three groups(P<0.05).Had the highest incidence of tube blockage in group A and the lowest incidence of tube blockage in group C.Seal the indwelling needle tube with 83.3 U/mL heparin in patients without coagulation dysfunction can significantly reduce the incidence of tube blockade and prolong time of indwelling.
