Abstract: Objective To evaluate the efficacy and safety of the new type and domestic made temporary hemodialysis catheter for hemodialysis patients. Methods A total of 140 patients in need of temporary central vein catheterization for hemodialysis from Oct. 2013 to Oct. 2014 in the two clinical centers were enrolled in this study. Patients were randomly divided into two groups. Half of the patients used the new type temporary hemodialysis catheter, and the rest of the patients used arrow temporary hemodialysis catheter for hemodialysis. The quality, manipulation, blood flow, dialysis adequacy and complications were compared between the two groups. Results The average age of the patients was 61.06±16.02 years. In test group, the average blood flow was 215.43±10.03 ml/min, indwelling duration was 30.49±15.65 days, spKt/V was 1.23±0.04, URR was 66.16±2.11%, and the scores of quality and ease of use were 99.84%, which had no differences from the control group (t=- 1.865, P=0.064 for blood flow; t=- 0.827, P=0.409 for indwelling duration; t= -1.601, P=0.112 for spKt/V; t=-1.791, P=0.075 for URR; and χ2=-1.000, P=0.321for the scores of quality and ease of use). The incidence of adverse event was 2.86% in test group and 1.43% in control group (χ2=0.000, P=1.000). There was no treatment-related serious adverse effect in both groups. Conclusion This clinical study shows that the new type and domestic made temporary hemodialysis catheter is effective and safe for temporary blood access in hemodialysis patients.
