摘要
选择静脉留置针输液病人３００人次，将其随机分为生理盐水组（１５０人次）及肝素钠组（１５０人次），分别采用生理盐水和肝素钠液作为封管液，结果两组在通管有效方面无差异（Ｐ＞０．０５）。
Selected 300 patients(times)received to vein permanent perfusion were divided randomly into 2 groups of normal saline and natrium heparin as tube-sealing solution respectively.Results showed that the effectiveness through tube was no difference between the 2 groups(P>0.05),indicating that normal saline as tube-sealing solution can be used to the patients unsuitable to the use of natrium heparin.
