血液透析是治疗急、慢性肾衰的有效方法,良好的血管通路是保证血液透析顺利进行和充分透析的关键。随着肾衰竭维持性血液透析患者中老年、肥胖、糖尿病人群发病率不断增加,血管通路的建立越来越困难。对这些血管条件差的患者,当动静脉内瘘失败,无法重建时,往往选择中心静脉进行置管,建立血液透析的血管通路,所以保持中心静脉导管的通畅,是保证患者充分血液透析的前提。本文将我院泌尿内科 Hemodialysis is an effective method to treat acute and chronic renal failure. Good vascular access is the key to ensure the smooth and thorough hemodialysis. With the increasing incidence of middle-aged, obese and diabetic patients in maintenance hemodialysis patients with renal failure, the establishment of vascular access is more and more difficult. In these patients with poor vascular conditions, when the failure of arteriovenous fistula, can not be reconstructed, often choose the central venous catheter, the establishment of hemodialysis vascular access, so to maintain the central venous catheter patency, is to ensure that patients with adequate hemodialysis premise .
