Continuous veno-venous hemofiltration and intermittent hemofiltration in treatment of type 1 cardiorenal syndrome: A clinical research / 第二军医大学学报

ABSTRACT

Objective To compare the effects of continuous veno-venous hemofiltration (CVVH) and intermittent hemofiltration (IHF) on the hemodynamics and clinical outcomes of patients with type 1 cardiorenal syndrome. Methods From May 2008 to June 2011, 34 patients diagnosed with type 1 cardiorenal syndrome were admitted to our hospital and received CVVHQ9 cases) or IHF (15 cases). The general data, acute hemodynamic changes before and after hemofiltration and clinical outcomes at 28 days after hemofiltration were evaluated. Results There were no significant differences in the heart rates, diastolic blood pressure between the two groups before and after hemofiltration (P>0.05). The systolic pressure was similar between the two groups before hemofiltration (P>0.05), but that in the IHF group was significantly lower than that in the CVVH group after hemofiltration (P0.05), but the minimal mean pressure in IHF group was significantly lower than that in the CVVH group (P0.05). Multivariate analysis suggested that APACHE II was the main influence factor of 28-day mortality of patients, and APACHE II and net ultrafiltration were the main influence factor of the minimal mean pressure. Conclusion Compared with IHF, CVVH fails to greatly reduce the mortality of patients with type 1 cardiorenal syndrome. The severity of the disease is the main influence factor for the hemodynamic changes and the 28-day mortality of patients with type 1 cardiorenal syndrome.
