研究目的:

(1)主要目标:比较枸橼酸钠封管液与肝素封管液在ICU血液净化导管中导管功能障碍发生率的差异。 (2)次要目标:比较两组患者在导管保留时间、导管相关血流感染、导管相关血栓形成、导管相关感染、穿刺部位出血事件、ICU住院时间等方面的差异。  

Objectives of Study:

(1) Primary objective: To compare the differences in the incidence of catheter dysfunction between sodium citrate lock solution and heparin lock solution in ICU blood purification catheters. (2) Secondary objectives: To compare the differences between the two groups of patients in terms of catheter retention time, catheter-related bloodstream infections, catheter-related thrombosis, catheter-related infections, puncture site bleeding events, ICU length of stay, and other aspects.
