目的 探讨3种不同封管方法对植入式静脉输液港的影响,选择最佳封管方法.方法 将植入静脉输液港的乳腺癌患者60例随机分为A、B、C组各20例.A组每天输液完毕用20mL生理盐水脉冲式冲管,再用5mL生理盐水正压封管,1个输液周期结束,拔除蝶翼针时用20mL生理盐水脉冲式冲管,再用5mL生理盐水正压封管;B组每天输液完毕用20mL生理盐水脉冲式冲管,再用5mL肝素盐水(0.05U/L)正压封管,拔除蝶翼针用20mL生理盐水脉冲式冲管,再用5mL肝素盐水(0.05U/L)正压封管;C组每天输液完毕用20mL生理盐水脉冲式冲管,再用5mL生理盐水正压封管,1个输液周期结束,拔除蝶翼针时先用20mL生理盐水脉冲式冲管,再用5mL肝素钠盐水(0.05U/L)正压封管.比较3组患者输液港堵管发生率.结果 A组与B组比较,A组与C组比较,输液港堵管发生率差异均有统计学意义(P＜0.01);B组与C组比较,输液港堵管发生率差异无统计学意义(P＞0.05).结论 每天输液完毕用20mL生理盐水脉冲式冲管,再用5mL生理盐水正压封管,1个输液周期结束,拔除蝶翼针时先用20mL生理盐水脉冲式冲管,再用5mL肝素钠盐水(0.05U/L)正压封管,方法最佳,经济实惠,没有安全隐患,堵管发生率低.%Objective To explore the effect of three different methods of sealling the duct of the implantable vascular access devices, and choose the best method. Methods A total of 60 breast cancer patients who used implantable vascular access devices were randomly divided into group A, B and C with 20 patients in each group. Group A, after transfusion everyday, 20mL normal saline ( NS ) was used to flush the duct by pulsed -wave mode and 5mL NS to seal the duct by positive pressure. Then the same method was used to seal the duct at the end of every transfusion cycle before pulling out the butterfly wing needle. Group B,After transfusion everyday,20mL NS was used to flush the duct by pulsed -wave mode and 5mL heparin saline ( 0. 05U/L ) to seal the duct by positive pressure. Before pulling out the butterfly wing needle,20mL NS was used to flush the duct by pulsed -wave mode first,then 5mL heparin saline ( 0. 05U/L ) to seal the duct by positive pressure. Group C,after transfusion everyday,20mL NS was used to flush the duct by pulsed - wave mode and 5mL NS to seal the duct by positive pressure,but at the end of every transfusion cycle, the same method was used as group B to seal the duct before pulling out the butterfly wing needle. Finally, the incidence rate of the duct obstruction was compared among the three groups. Results There were statistically significant differences between group A and B, group A and C in the incidence rate of the duct obstruction ( P <0. 01 ). Between group B and C ,the incidence rate of duct obstruction had no statistical difference( P > 0. 05 ). Conclusion After transfusion everyday, 20mL NS was used to flush the duct by pulsed - wave mode and 5mL NS to seal the duct by positive pressure, but at the end of every transfusion cycle, first 20 mL NS was used to flush the duct by pulsed - wave mode, then 5mL heparin saline ( 0. 05U/L ) was used to seal the duct by positive pressure before pulling out the butterfly wing needle. It is a good method which is not only economic, but also safe and the incidence rate of duct obstruction is low.
