本文应用连续动静脉血液滤过(CAVH)系列中的连续静脉静脉血液滤过(CVVH)及连续静脉静脉血液透析滤过(CVVH DF)治疗危重病人32例.结果表明,CAVH系列能有效地解除过度的水负荷,其平均超滤率达622ml/h,对血尿素氮、肌酐也有较好的清除,与治疗前相比,差异显著(P<0.01),而心血管并发症少.提示CAVH方法能较好地配合用于多器官功能衰竭等一类危重病的治疗. In this paper, continuous venous venous hemofiltration (CVVH) and continuous intravenous venous hemodiafiltration (CVVH DF) in the series of continuous arteriovenous hemofiltration (CAVH) were used to treat 32 critically ill patients.The results showed that the CAVH series can effectively release Excessive water load, the average ultrafiltration rate of 622ml / h, on the blood urea nitrogen, creatinine clearance better, compared with before treatment, the difference was significant (P <0.01), and less cardiovascular complications. CAVH prompted The method can be well used in the treatment of a series of critical diseases such as multiple organ failure.
