目的:比较股静脉、锁骨下静脉和颈内静脉插管留置双腔导管在血液透析中的应用.方法:106例尿毒症患者,40例行股静脉插管,36例行锁骨下静脉插管,30例行颈内静脉插管进行血液透析(血透).观察三种不同插管途径的血流速度、评估透析的充分程度(KT/V值)、血尿素氮重复循环率、导管留置时间以及与导管相关的并发症.结果:颈内静脉和锁骨下静脉插管的血流速度、透析效能、导管留置时间均明显高于股静脉插管,而锁骨下静脉和股静脉插管的并发症则较多.结论:三种方法比较,颈内静脉插管是一种相对更理想的血透临时性血管通路.“,”Objective: To compare the utility of bia catheter left in subclavical vein, femoral vein or intracervical vein in hemodialysis Methods: To investigate the blood flow velocity, KT/V value, blood urea nitrogen(BUN) recycling rate, retaining time of vein catheter and the complication associated with catheter 106 cases with uremic patients carried on hemodialysis, 36 cases were placed the bia catheter in subclavical vein, 40 cases in femoral vei...
