目的：探讨肝素稀释液用于肺心病患者静脉留置针封管是否优于生理盐水。
Objective To explore whether tube sealing on trochar with heparin dilution liquid is excellent than sodium chloride in patients with pneumocardial disease.
2
结果：生理盐水封管组浅静脉留置针阻管发生率为22.1%，而肝素钠封管组为7.4%，后者显著少于前者（P<0.05）。
Results :The occlusion rate of superficial vein detained needle was 22.1% in group of normal saline, but 7.4% in group of heparin sodium(P<0.05).
3
结果两组患者封管效果、留置针留置时间及封管的维持时间比较，差异无统计学意义（P＞0.05）。
Results There was no significant(P>0.05) in the effects of sealing tube, catheter indwelling time and the duration of sealing tube.
