成人PICC堵塞的预防及处理专家共识

Prevention and management of PICC occlusion in adults:an expert consensus

经外周静脉置入中心静脉导管(PICC)作为静脉治疗通路应用广泛,而导管堵塞是PICC使用过程中最常见的并发症之一,发生导管堵塞可能导致拔管或重新置管,延长患者住院时间,增加医疗费用,影响治疗的实施与患者的预后。导管堵塞的预防及处理意义重大,日常维护与护理操作应完整规范、执行到位,需建立基于证据的标准流程以满足临床工作需要。本共识遵循WHO指南制订手册提供的方法与原则,形成包括PICC通畅性评估、堵塞程度及类型评估、风险因素预防、堵塞处理在内的系统性规范化临床实践流程,以期减少PICC相关并发症,保障PICC使用寿命及患者治疗安全。

Peripherally inserted central catheter(PICC)is widely used as an intravenous therapy pathway,and catheter occlusion is one of the most common complications during the use of PICC.Catheter occlusion may lead to extubation or re-catheterization,which may generate prolonged hospital stay and increased medical costs,thus affecting the implementation of treatment and patient prognosis.The prevention and treatment of occlusion are of great significance.Daily maintenance and nursing operations should be complete,standardized and implemented in place.Evidence-based standard procedures should be established to meet the needs of clinical work.This consensus follows the methods and principles provided in the WHO guidelines formulation manual,and forms a systematic and standardized clinical practice process,including PICC patency assessment,catheter occlusion degree and type assessment,risk factor prevention,blockage management,etc.The purpose of this consensus is to reduce catheter-related complications,ensure the longevity of PICC and the safety of patient treatment.
