Abstract:
Objective To investigate the effect of continuous venous-venous hemofiltration (CVVH) and continuous venous-venous hemodialysis (CVVHD) on patients with lactic acidosis.Methods A total of 137 cases with lactic acidosis were included in this prospective randomized control study.lhe patients were collected from the University of Hong Kong-shenzhen Hospitall and the First Affiliated Hospital of Shantou University Medical College from April 2009 to April 2013.Inclusion criteria were patients with lactic acidosis.Exclusion criteria were patients with end-stage malignancy or terminal stage of illnesses.The patients were randomly divided into two groups:CVVH group and CVVHD group,and patients of both group were intervened with conventional treatments as well.For each group,the lactic acid and blood gas analysis were tested before CRRT,and at 4 hours,8 hours,12 hours,24 hours,and 48 hours of CRRT.The patients' mortality and length of ICU stay time were analysed and recorded.Statistical analysis was performed using SPSS 15.0software.Results When the length of time for treatment was the same,the efficacy between CVVH group and CVVHD group showed no difference in blood lactic acid level [4 h:(11.65 ± 3.39) mmol/L vs.(11.12±2.65) mmol/L; 8 h:(8.78±2.35) mmol/L vs.(8.59±2.09) mmol/L; 12 h:(6.91 ±1.67)mmol/Lvs.(6.74±1.76) mmol/L;24h:(1.66±0.39) mmol/Lvs.(1.51±0.30) mmol/L; 48 h:(0.95 ±0.24) mmol/L vs.(0.66 ±0.20) mmol/L,P ＞ 0.05) and pH value [4 h:(6.93 ±0.14) vs.(7.05±0.09);8h:(7.04±0.10)vs.(7.12±0.05); 12h:(7.13±0.07)vs.(7.20±0.04);24h:(7.30±0.03) vs.(7.38±0.04); 48h:(7.41 ±0.03) vs.(7.46±0.02),P＞ 0.05].There are also no difference in the hospital mortality (11.4％ vs.10.4％,P=0.854) and length ofICU stay time [(9.5 ±2.4) d vs.(8.8 ± 2.9) d,P =0.329].Conclusions Both CVVH and CVVHD can effectively correct hyperlactemia,enhance acid-base balance,contributing no differences in length of ICU stay time and patients' hospital mortality.
