稳定可靠的血管通路是血液透析治疗顺利进行的保证。近年来,随着老年及糖尿病等血管条件差的患者的增加,经皮下隧道留置带袖套的中心静脉导管的使用率越来越高;许多慢性肾衰竭患者因未能及时建立动静脉内瘘,也只能以临时性中心静脉导管作为通路开始血液透析。但中心静脉导管相 Stable and reliable vascular access is a guarantee of successful hemodialysis treatment. In recent years, with the increase of patients with poor vascular conditions, such as the elderly and diabetes, the use of central venous catheters for percutaneous tunnel placement of cuffs is getting higher and higher. Many patients with chronic renal failure are unable to establish arteriovenous fistula in time , Hemodialysis can only be started with a temporary central venous catheter as access. But the central venous catheter phase
