研究目的:

本研究旨在探讨改良预冲法无肝素透析技术在出血及高危出血倾向患者中的安全性与有效性,优化无肝素透析操作流程。核心目的是解决现有无肝素透析技术在临床应用中的关键瓶颈。降低无肝素透析过程中的体外循环凝血风险,提高透析器和管路的有效使用时间;在避免肝素类抗凝剂使用的前提下,保证有效透析时间;减少因凝血导致的透析中断、治疗效果下降及患者急性并发症的发生。  

Objectives of Study:

This study aims to investigate the safety and efficacy of the modified priming method for heparin-free dialysis in patients with bleeding or high-risk bleeding tendencies, with the goal of optimizing the operational protocol for heparin-free dialysis. The core objective is to address critical bottlenecks in the clinical application of existing heparin-free dialysis techniques. Specifically, it seeks to reduce the risk of extracorporeal circuit clotting during heparin-free dialysis, extend the effective utilization time of dialyzers and tubing, ensure adequate dialysis duration without the use of heparin-based anticoagulants, and minimize dialysis interruptions, decreased treatment efficacy, and acute complications in patients caused by clotting events.

干预措施:

使用800-1000ml 0.9%氯化钠注射液预冲管路,闭式循环15分钟(血流量260ml/min),无需肝素吸附。透析中每30分钟用200ml生理盐水冲洗管路。传统无肝素透析(每隔30min生理盐水冲洗200ml)

干预措施代码:

Intervention:

Use 800–1000 mL of 0.9% sodium chloride injection to prime the circuit, then circulate in a closed loop for 15 minutes (blood flow rate 260 mL/min). No heparin adsorption is required. During dialysis, flush the circuit with 200 mL of normal saline every 30 minutes.Dialysis process: Adjust the flushing frequency according to coagulation status.
