研究目的:

(1)探讨甲磺酸萘莫司他抗凝的CRRT行透析管路采血代替外周血管采血监测抗凝效果的可行性,旨在减少患者血液净化过程中的采血创伤和痛苦,并为规范NM抗凝监测采血程序提供科学依据。 (2)探讨不同体外循环连接方式(正接和反接)对透析管路采血替代外周血管采血的监测结果的影响。 (3)探讨甲磺酸萘莫司他泵停泵不同时长对透析管路采血时监测结果有无影响,以优化抗凝监测流程,减少因停泵采血造成体外循环凝血的风险,确定采血最佳方案。  

Objectives of Study:

(1) To explore the feasibility of CRRT anticoagulated with nafamustat mesylate by dialysis tube blood collection instead of peripheral blood blood collection to monitor the anticoagulation effect, aiming to reduce the trauma and pain of blood collection during the blood purification process of patients, and provide a scientific basis for standardizing NM anticoagulation monitoring blood collection procedures. (2) To explore the influence of different cardiopulmonary bypass connection methods (forward connection and reverse connection) on the monitoring results of blood collection from the dialysis line instead of blood collection from peripheral blood vessels. (3) To explore whether different time stops of nafamostat mesylate pump have any influence on the monitoring results of dialysis line blood collection, so as to optimize the anticoagulation monitoring process, reduce the risk of cardiopulmonary bypass coagulation caused by pump stopping blood collection, and determine the best blood collection plan
