目的：探讨导管后端修剪联合更换连接器在PICC患者导管堵塞中的应用。方法12例患者置入后端修剪式PICC，发生连接器堵管，采取常规堵管处理无效时，经后端修剪联合更换连接器后，冲洗导管。结果12例患者中，8例患者行导管修剪并更换连接器后，用20 mL肝素稀释液脉冲式冲管，导管通畅。4例患者行导管修剪并更换连接器后，冲洗导管仍有一定阻力，再给予稀释尿激酶注射液进行溶栓处理，0.5~3 h后，导管通畅。结论对导管连接器发生堵管PICC患者，行后端修剪联合更换连接器，方法安全简单有效，避免拔除导管，不仅减少了患者医疗费用，而且避免患者再次置管的痛苦。

Objective To explore the effect of backend pruning and connector changing on catheter blockage of 12 cases with PICC tube. Methods Connector obstruction occurred in 12 patients with PICC tube. After the failure of conventional processing for obstruction, backend pruning and connector changing were conducted then the tube was flushed. Results for eight patients of twelve, after tube pruning and connector changing, the tube was flushed with 20 mL heparin dilution and smoothness was achieved. For another four patients, after the flushing with heparin dilution, no smoothness was observed, thus thrombolysis was carried out. Conclusion Backend pruning and connector changing are economical and practical methods for catheter obstruction. In addition, standardized nursing and operation can effectively reduce the incidence of connector obstruction, so as to reduce the economic burden of patients and improve the quality of life of patients.
