经外周静脉置入中心静脉导管(peripherally inserted central catheter,简称PICC)是一种由外周静脉(贵要静脉、肘正中静脉、头静脉)穿刺的中心静脉导管,其导管尖端位于上腔静脉或锁骨下静脉~([1])。PICC留置时间可长达1年,减轻了患者多次静脉穿刺的痛苦和操作者的压力~([2]),也避免了反复静脉穿刺或化疗药物外渗引起的静脉炎~([3])。另外,PICC操作较为简便,还不会出现中心静脉导管(CVC)插管时所引起的出血和气胸等机械并发症,其安全性较高。尽管PICC对于
Peripherally inserted central catheter (peripherally inserted central catheter, PICC) is a central venous catheter punctured by the peripheral vein (VIP vein, elbow median vein, head vein), the catheter tip is located in the superior vena cava or clavicle Under the vein ~ ([1]). PICC retention time can be as long as 1 year, reducing the patient’s multiple venipuncture pain and operator pressure (2), but also to avoid repeated venipuncture or chemotherapeutic drug-induced phlebitis ~ (3) ). In addition, PICC operation is relatively simple and does not appear the central venous catheter (CVC) intubation caused by bleeding and pneumothorax and other mechanical complications, its safety is higher. Although PICC for
