连续性血液净化体外循环静脉壶凝血的危险因素分析及预防措施进展

摘要

Continuous blood purification is a group of extracorporeal blood purification techniques therapy technology,because of its continuous,slow removal of water and solute characteristics,It has become an important auxiliary method in the treatment of criti-cal patients. The clotting of bubble chamber in cardiopulmonary bypass(CPB)is a difficult problem in the process of continuous blood purification treatment. This article elaborates the factors such as the level of bubble chamber,CBP treatment time,blood flow velocity, patient's internal environment,anticoagulant way and so on.We provide a guidance for the targeted nursing intervention of critically pa-tients who are undering CBP treatment.%连续性血液净化(CBP)是一组体外血液净化治疗技术,因其连续、缓慢清除水分及溶质的特点,已成为危重病救治中的重要辅助手段.而体外循环静脉壶凝血是CBP治疗过程中的一大难题.文章从静脉壶的液面高度、CBP的治疗时间、血流速度、患者内环境、抗凝方式等方面因素进行阐述,为行CBP治疗的危重症患者进行针对性护理干预提供指导.
