摘　　要：目的探讨不同浓度肝素钠溶液封管与锁骨下静脉留置管堵塞关系。方法对进行锁骨下静脉穿刺置管术的肿瘤患者共889例，分A、B两组进行观察，A组在输液前后用肝素钠盐水（50μ/ml）5ml冲管，B组肿瘤患者输液前后用肝素钠盐水（125μ/ml）5ml冲管，两者均采用正压封管。统计学方法采用，检验。结果A组导管堵塞发生率为5．55％，B组导管堵塞发生率为1．13％，两者比较有显著性差异（P〈0．01）。结论应用不同浓度肝素钠溶液冲管与导管堵塞有关系，研究结果表明，用肝素钠盐水（125μ/ml）5ml冲管能有效降低导管堵塞发生率。Objective To investigate the relationship of sealing catheter with different concentration of heparin sodium and obstruction after pereutaneous insertion of subclavian venous catheters. Methods A total of 889 cases of tumor with pereutaneous insertion of subclavian venous catheters were individed into two groups, group A was flushed with （50 U/nd） 5 ml heparin sodium before and after infusion, and group B were flushed with （S0 U/ml） 5 ml beparin sodium before and after infusion. Results 5.55% （25/889） of catheter obstruction in group A were occurred and 1.13% （5/889） of catheter obstruction in group B were occurred, there was signification difference between the two groups （P 〈 0. 05） . Conclusions There is an obvious relationship of sealing catheter with different concentration of heparin sodium and obstruction after percutaneous insertion of subclavian venous catheters. Flushing catheter with 125 U/nd heparin sodium can reduce the catheter obstruction rate effectively.
