封管液预防中心静脉导管堵塞的研究进展

Research progress on the causes and preventive measures of central venous catheter blockage

中心静脉导管(CVCs)现已广泛应用于重症医学科的急危重病救治、液体复苏、药物输注、胃肠外营养、血流动力学监测、化疗以及连续性血液净化治疗等。尽管CVCs的应用可为临床医疗护理工作提供便利,但患者在使用的同时会发生各种各样置管并发症的比例要超过15%,此外,导管堵塞的发生率约为25%。目前认为充分的冲管和有效的封管是减少和预防导管堵塞的重要手段。本文就不同封管液预防中心静脉导管堵塞进行综述,以期为临床护理人员预防中心静脉导管堵塞提供参考。

Central venous catheters(CVCs)are now widely used in critical care for critical care,fluid resuscitation,drug infusion,parenteral nutrition,hemodynamic monitoring,chemotherapy,and continuous blood purification treatment.Although the application of CVCs can facilitate clinical medical care work,the proportion of patients with various catheter complications will exceed 15%,and the incidence of catheter blockage is about 25%.At present,adequate flushing and effective sealing are considered to be important means to reduce and prevent catheter blockage.This article reviews the prevention of central venous catheter occlusion with different sealing fluids,in order to provide reference for clinical nurses to prevent central venous catheter occlusion.
