研究目的: |
探讨不同封管频次对重症监护病房CRRT治疗后透析导管未拔除患者导管功能障碍发生率、导管存活时间的影响,确定相对较低导管功能障碍风险的封管频次。同时评估不同封管频次对导管通畅性的维持效果及导管相关血流感染的影响,找出能较好平衡感染风险与保持导管通畅的封管策略。 |
||||||||||||||||||||||
|
Objectives of Study: |
To investigate the impact of different catheter locking frequencies on the incidence of catheter dysfunction and catheter survival time in patients with dialysis catheters not removed after CRRT treatment in the intensive care unit, and to determine the locking frequency with relatively lower risk of catheter dysfunction. At the same time, to evaluate the effect of different locking frequencies on maintaining catheter patency and their influence on catheter-related bloodstream infections, in order to find a locking strategy that can better balance the risk of infection and maintaining catheter patency. |

随机方法(请说明由何人用什么方法产生随机序列): |
该试验包括需要 CRRT 的重症监护病房 (ICU) 患者,患者以 1:1的比例随机分为2组,由中央计算机生成的随机序列确定。A组为24h封管一次,B组为72h封管一次。 |
||||||||
|
Randomization Procedure (please state who generates the random number sequence and by what method): |
This trial includes ICU patients requiring CRRT, who are randomly assigned to two groups at a 1:1 ratio based on a randomization sequence generated by a central computer. Group A receives catheter locking every 24 hours, while Group B receives catheter locking every 72 hours. |

|
Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture: |
Data Collection: Data were collected using the hospital's electronic information system and an Excel spreadsheet for case information recording. Data Management: The research team managed the data using the Excel spreadsheet for case information and ultimately uploaded it to the hospital's scientific research system for centralized management. |
