改良冲管方法预防经PICC输注多烯磷脂酰胆碱注射液管路堵塞的效果观察

Improved pipe-washing prevents blockage of PICC for polyenephosphatidy lcholine infusion

目的探讨改良冲管方法对预防经PICC输注多烯磷脂酰胆碱注射液堵管的效果。方法将2014年4月-2015年3月收治的应用多烯磷脂酰胆碱注射液治疗的15例患者作为对照组,将2015年4月-2016年3月收治的应用多烯磷脂酰胆碱注射液治疗的18例患者作为改良组。对照组患者采用常规方法冲管,即输液前后予0.9%氯化钠注射液10mL脉冲式冲管;改良组患者应用改良方法冲管,即在常规冲管的基础上,在输注多烯磷脂酰胆碱注射液前后加用5%葡萄糖注射液50mL静脉点滴冲管,和5%葡萄糖注射液10mL脉冲式冲管。比较两组患者PICC输液测试是否堵管时的最大滴速及堵管情况。结果改良组末次输注测试是否堵管时的最大滴速高于对照组;改良组患者输液堵管情况少于对照组,两组比较,差异有统计学意义(均P<0.05)。结论改良冲管方法能有效降低因输注多烯磷脂酰胆碱注射液堵管情况的发生。

Objective To discuss the impact of improved pipe-washing on blockage of PICC for infusion of polyene phosphatidylcholine injection（PPI）. Methods A total of 15 patients treated with infusion of PPI from April 2014 to March 2015 were chosen as the control group by convenience sampling method, while another 18 patients treated with PPI from April 2015 to March 2016 were selected as the experimental group. In the control group the pipes were washed with 0.9% 10 mL sodium chloride injection before PPI infusion, while in the experimental group improved pipe washing method was applied. We compared the two groups in terms of the maximum number of transfusion drops and rate of unplanned extubation caused by pipe blockage. Results The maximum number of transfusion drops for pipe biockage test in the experimental group was significantly greater than that in the control group（P0.01）. The incidence of pipe blockage was smaller than that in the control group（P〈0.01）. Conclusion Improved pipe washing method can effectively reduce rate of tube blockage.
