三种封管液对小儿留置针的影响比较

目的探讨三种封管液对小儿留置针留置效果的影响。方法选择需静脉留置套管针输液的患儿100例,随机分为1、2、3三组,分别采用50 U/ml的肝素钠盐水、10 U/ml的肝素钠盐水和生理盐水作为封管液,对三组留置针的留置时间、静脉炎和堵管发生率进行比较。结果 1组的留置时间明显优于2、3组(P0.05),三组之间静脉炎和堵管发生率的比较无统计学意义(P0.05)。结论 50 U/ml肝素盐水封管效果优于10 U/ml肝素盐水和生理盐水。

Effect of Three Different Flush Solutions on the Peripheral Intravenous Catheters in Pediatrics

Objective To compare the effect of 3 different flush solutions on the peripheral intravenous catheters in Pediatrics. Methods One hundred hospitalized Pediatric patients carrying a peripheral intravenous catheter were randomly divided into three groups. Then three groups were subjected to catheter flushing with a syringe prefilled with 50 U/ml of combination heparin and saline,10 U/ml heparin saline, normal saline,respectively.The indwelling time ,the phlebitis rates and the incidence of catheter blocking among 3 groups were compared,re?spectively.Results The indwelling time of group 1 was longer than that of group 2 and 3(P<0.05).The phlebitis rates and the incidence of catheter blocking among 3 groups were not significantly different (P>0.05).Conclusion The flush solution of 50 U/ml heparin saline could be better than other two groups.
