摘要
目的观察不同封管液对留置针堵管率及静脉炎发生率的影响,为临床封管液的选择提供实证依据。方法选取留置静脉留置针的住院患者150例,随机分为三组:生理盐水组、50U/mL肝素盐水组、100U/mL肝素盐水组,每组各50例,分别采用生理盐水、50U/mL肝素盐水、100U/mL肝素盐水封管,观察比较三组静脉留置针堵管及静脉炎发生率。结果生理盐水组堵管率为32.0%、50U/mL肝素盐水组为14.0%、100U/mL肝素盐水组为10.0%,三组比较,差异有统计学意义(P<0.05)。三组静脉炎情况比较,差异有统计学意义(P<0.05),其中100U/mL肝素盐水组最重。结论50U/mL肝素盐水封管可在一定程度上防范留置针堵管,不增加静脉炎发生的危险,因此,效果优于生理盐水和100U/mL肝素盐水。
Objective To compare the effect of 3 different flush solutions used to flush out the peripheral intravenous catheters on incidence rates of catheter blocking and phlebitis,to provide an objective reference for clinical nurses to select a safe flush solution. Methods Totally, 150 hospitalized patients carrying a peripheral intravenous catheter were randomly divided into three groups of 50 each,and were subjected to catheter flushing with a syringe prefilled with normal saline （the NS group）, 50 U/mL of combination heparin and saline （the low-dose group）,100 U/mL heparin saline （the high-dose group）. The incidence rates of catheter blocking and phlebitis in the 3 groups were compared. Results The incidence rates of catheter blocking was 32.0% in the NS group, 14.0% in the low-dose group and 10.0% in the high-dose group, with statistical difference between the 3 groups （P〈0.05）. There was significant difference in phlebitis rates among the 3 groups （P〈0.05）, with the high-dose group sustaining the most severe injuries. Conclusion The low-dose heparin （50 U/mL ） used as a flush solution could prevent catheter blocking without increasing the risk of phlebitis,being better than normal saline or 100 U/mL heparin saline.
