四种浓度肝素钠稀释液予静脉留置针封管的效果比较

目的：探讨肝素钠用于静脉留置针封管的最佳浓度,为指导临床有效减少导管堵塞的发生率提供可靠的理论依据.方法： 将入选对象根据入院时间的先后顺序接受浓度25U/ml、50U/ml、75U/ml、125U/ml肝素钠稀释液封管分为4组,每组50人,观察留置针保留时间.结果： 4组留置针保留时间,经统计学分析25U/ml组与125U/ml组差异无统计学意义P〉0.05;25U/ml组与75U/ml组差异有统计学意义P〈0.05;75U/m组与125U/ml组差异有统计学意义P〈0.05.结论： 75U/ml肝素钠稀释液减少堵管的发生率，使经静脉留置针输液顺利进行.

Four kind of density heparin sodium diluent to give the vein leaving alone needle tube sealing the effect to compare

ObjeetiveTo investigate the heparin intravenous catheter sealed tube for the optimal concentration for clinical effective in reducing the incidence of catheter blockage and provide a reliable theoretical basis. Methods：Selected objects received under a hospital order in time the concentration of 25U/ml,50U/ml, 75U/ml, 125U/ml heparin dilution sealed tube divided into 4 groups of 50 people, observe the catheter retention time. Resuits：4 catheter retention time, the statistical analysis 25U/ml group and 125U/ml no significant difference between groups P〉 0.05;25U/ml group and 75U/ml group difference was significant P 〈0. 05;75U / m group and 125U/ml group difference was significant P 〈0.05. Conclusion：75U/ml diluted heparin to reduce the incidence of plugging,so that infusion of intravenous catheter smoothly.
