简介:目的探讨耐高压PICC导管在结直肠癌患者CT检查中的应用效果。方法选取自2014年1月至2016年1月在本院进行首次化疗的结直肠癌患者120例.分为观察组和对照组各60例。观察组经耐高压PICC导管注入造影剂行增强CT检查,而对照组患者经外周静脉留置针注入造影剂行增强CT检查。比较两组患者行增强CT检查时的造影剂外渗发生率、护理耗时及导管维护费用的差异。结果观察组患者造影剂的外渗发生率(0vs.5%,P=0.022),护理耗时[(6.36±7.71)分钟/次诋(13.32±3.29)分钟/次,P=0.001],导管维护费用[(1186.31±165.36)元/次眠(1250.25±170.67)元/次.P=0.0391均低于对照组。结论在结直肠癌患者中经耐高压PICC导管行增强CT检查,能降低造影剂外渗的发生率.减少护理时数.降低维护费用。
