The use of permanent double lumen hemodialysis catheters (PermCath, Quinton, Seattle, WA) was surveyed in 17 dialysis units with a total of 1,372 patients. During the period of study, 210 patients received or already had such catheters. Their use varied widely, being highest in units dialyzing many older patients with associated diseases and difficulties with vascular access. Flow problems occurred in 46% and clotting in 24%; 27% required urokinase (at least once), and 10% received some form of anticoagulation. Local infections occurred in 15% and septicemia (at least once) in 15%. Some older patients elected to continue with this form of "painless" dialysis.
在17个透析单位对1372名患者使用永久性双腔血液透析导管（PermCath，昆顿公司，西雅图，华盛顿州）进行了调查。在研究期间，210名患者接受了此类导管或已经有此类导管。其使用情况差异很大，在透析许多患有相关疾病且血管通路有困难的老年患者的单位中使用率最高。46%的患者出现血流问题，24%的患者出现凝血；27%的患者需要使用尿激酶（至少一次），10%的患者接受了某种形式的抗凝治疗。15%的患者发生局部感染，15%的患者发生败血症（至少一次）。一些老年患者选择继续采用这种“无痛”透析方式。
