输入液体在小儿静脉留置针封管中的应用研究

目的探讨直接使用输入的液体进行小儿静脉留置针封管的可行性及效果。方法将120例患儿随机分为A、B、C三组,每组40例,A组用生理盐水,B组用肝素钠稀释液,C组直接使用输入的原液体进行封管,观察静脉留置针的留置时间、封管时间、堵管、外渗、静脉炎的发生率。结果C组与A组,C组与B组静脉留置时间、平均封管时间、堵管、外渗、静脉炎的发生率比较差异无统计学意义(P>0.05)。结论直接使用输入的液体进行封管具有操作简便、节省资源等优点,故此法是可行的、有效的。

Effect of infused liquid for intravenous catheter lock in pediatric patients

Objective To evaluate the feasibility and efficacy of infused liquid used for sealing up the intravenous indwelling catheter directly in pediatric patients. Methods A total of 120 pediatric patients were randomly divided into three groups, with 40 cases in each group. Patients in group A and group B used normal saline and heparin solution for intravenous catheter lock respectively. And patients in group C used infused liquid for sealing up the indwelling catheter directly. A comparative study about the incidence of catheter occlusion and infusion phlebitis as well as indwelling time was performed in the three groups. Results There were no differences between the group A and group C with regard to the incidence of catheter occlusion and infusion phlebitis as well as indwelling time. And there were no differences between the group B and the group C (P>0.05). Conclusion It is applicable and effective to use infused liquid for sealing up the intravenous indwelling catheter directly.
