Study of hemodialysis performance and recirculation ratios of subclavian catheter hemodialysis is reported. Data are compared to the results obtained when a conventional intrafistular single-lumen hemodialysis needle is used under similar conditions. Renal blood flow values were slightly but not significantly lower for subclavian hemodialysis. Small molecular extraction ratios were identical. Small molecular clearances were somewhat lower for the subclavian approach, especially at high dialyzer blood flow rates. However, the differences were not significant, and overall extraction ratios, calculated for the entire dialysis period with both access methods in 43 patients, were identical. Recirculation averaged 12.5% for the fistular approach and 20% for the subclavian approach. It is concluded that, as a whole, dialysis performance is somewhat lower with the subclavian vascular access method. This is mainly due to a higher recirculation rate, and in turn to the consequence of the length of the intravascular device. However, this minor differences do not necessitate changes in dialysis schedules.
报告了锁骨下导管血液透析的透析性能和再循环率的研究。将数据与在类似条件下使用传统的动静脉内瘘单腔血液透析针时获得的结果进行比较。锁骨下血液透析的肾血流量值略低,但差异不显著。小分子提取率相同。锁骨下途径的小分子清除率略低,尤其是在高透析器血流量时。然而,差异不显著,并且在43例患者中使用两种通路方法计算的整个透析期的总体提取率相同。动静脉内瘘途径的再循环平均为12.5%,锁骨下途径为20%。得出的结论是,总体而言,锁骨下血管通路方法的透析性能略低。这主要是由于再循环率较高,而这又是血管内装置长度的结果。然而,这种微小差异并不需要改变透析方案。
