外周静脉留置针不同封管液封管效果的研究

目的 比较外周静脉留置针两种封管液的封管效果。以选择更有效的封管液封管。减少临床上由于封管液选用不当而致堵管情况的发生，避免由于堵管而不得不再次穿刺给患者带来的痛苦。方法 将68例患者按随机抽样的方法分为对照组和实验组，每组均34例，对照组用0．9％生理盐水5ml封管。实验组用肝素盐水（50u／m1）5ml封管，两组均采用正压封管方法，进行留置效果比较。结果 实验组用肝素盐水（50u／ml）5ml封管。有效率为93．10％。对照组用0.9％生理盐水5ml封管，有效率为64．93％。经统计学处理χ^2=20．16．P〈0．01两组封管方法有显著性差异。肝素盐水封管优于生理盐水。结论 对外周静脉留置针而言．主张用肝素盐水封管。

Study on the Effect of the Different Liquids of a Vein Detains the Needle

OBJECTIVE To compare the effect of two kinds of liquids that is to seal the tube of a vein detains the needle is for to choice the liquid more effectively to seal the tube. That will reduce the situation that the tube will be closed, and will avoid the suffering to have to stab again. METHODS The methods is divided into 68 sufferers matched control and the experiment set. The method to divide is a random sampling. Each one is all 34. The matched control is 5 milliliters of to seal the tube with 0,9% physiology brine. Experimenting the set is 5 milliliters of to seal the tube with the heparin brine （50u/ml）. Two all adopt just press to seal to take care of the method, and then to compare the detention result＇ s, RESULTS Experimenting the set is 5 milliliters of to seal the tube with the heparin brine （50u/ml） .The efficience is 93,10%.The matched control is 5 milliliters of to seal the tube with 0.9% physiology brine, the efficience is 64.93%. The statistics result is that χ^2=20.16, P〈0.01. Two the sets seal to take care of the method to show the difference, the heparin brine seals the tube to surpass the physiology brine. CONCLUSION The heparin brine seals the tube surpass the physiology brine.A vein detains the needle should adopt the heparin brine to seal the tube, the result will be better.
