Abstract:
ObjectiveTo investigate the effect and outcome of critically illness with acute kidney injury (AKI) treated with continuous veno-venous hemodiafiltration (CVVHDF) in children.Methods Twenty-four cases of critically illness with AKI were treated with CVVHDF in our pediatric intensive care unit from Jan 2008 to Dec 2010.The levels of creatinine (Cr),blood urea nitrogen (BUN),K +,Na + and HCO3- were observed before CVVHDF and 6,12,24,48,72 h after CVVHDF.ResultsCatheter was successfully established for CVVHDF in 24 cases of AKI.The average duration of CVVHDF was 46 h ( 16 ～142 h).The blood levels of Cr and BUN were significantly decreased at 6 h after CVVHDF [ ( 196.3 ±112.4) μmol/L,( 13.3 ± 8.5 ) mmol/L] and 12 h after CVVHDF [ ( 106.1 ± 84.2) μ mol/L,( 10.2 ± 9.7 )mmol/L] as compared to those before treatment [ (340.6 ±298.2) μmol/L,(31.6 ± 11.3) mmol/L] (P ＜0.05,P ＜ 0.01 ).After 48 h of CVVHDF,the Cr,BUN returned to normal range.The imbalance of blood K +,Na +,and HCO3- improved at 6 h after CVVHDF and returned to nomal levels at 24 h.Total 28 d fatality rate was 29.2％ (7/24),and all death cases were complicated with multiple organ dysfunction syndrome.ConclusionCVVHDF therapy for AKI can quickly clear Cr,BUN and excess water,correct electrolyte disorders,improve kidney function in children.
