摘　　要：目的探讨肝素钠溶液与生理盐水冲封管方式在锁骨下中心静脉置管(锁穿)导管内赘生物形成及导管堵管率方面的差异。方法将126例腹部肿瘤锁穿患者按置管顺序随机分为肝素钠组(62人)和生理盐水组(64人),分别给予6～8ml肝素钠溶液(浓度为50U/ml)、生理盐水脉冲式冲封管。比较两种冲封管溶液引起的导管内赘生物形成情况、导管留置时间与堵管率等方面是否存在不同。结果肝素钠组与生理盐水组导管内赘生物情况、导管留置时间差异无显著意义,P>0.05;导管内赘生物情况与导管留置时间呈正相关,r=0.112;两组导管堵管率亦不存在统计学差异,P>0.05。结论生理盐水冲封管对导管内赘生物情况、导管堵管率等可以起到与肝素钠溶液冲封管相同的效果,且生理盐水符合人体内环境,对血管刺激小,操作简单方便,提高了护理工作的安全性、有效性。Objective To study the effects of the two different tube-sealing fluids in the formation of tube excrescence and tube-plugging. Method 126 stomach cancer patients with central venous catheter were randomly divided into heparin group and sodium group. For the heparin group, 6-8 ml heparin sodium （50 U/ml） was adopted for sealing trochar, and for the sodium group, 6-8 ml 0.9% normal saline was adopted for sealing troehar. The difference of tube excrescence and tube-plugging was compared. Result There were no differences in the formation of tube excrescence and the indwelling time between the heparin group and the sodium group（P〉0.05）. There was positive correlation between the formation of tube excrescence and the indwelling time. And there was no difference in tubeplugging between the two groups（P〉0.05）. Conclusion 0.9 % normal saline can achieve the effects of heparin sodium in the formation of tube excrescence and tube-plugging, so the normal saline can replace heparin sodium because of its low price and less infections.
