title: [A multicenter prospective clinical study on continuous blood purification in treating childhood severe sepsis].
abstract: OBJECTIVE
  To evaluate efficacy of continuous blood purification (CBP) in childhood severe sepsis through the analysis of organ function, inflammatory mediators and prognosis.
  
  
  METHODS
  Forty-seven children with severe sepsis aged 29 days -16 years who were treated in PICU of Shanghai and Zhejiang five hospitals during October 1, 2011 and September 30, 2012 were enrolled; 30 cases treated with CBP were recorded as logged group , 17 cases without CBP as unlogged group. Changes in the cardiovascular, respiratory function, renal function, inflammatory markers, PRISM score III, PCIS and survival were observed and compared between the two groups at baseline (d0), first days (d1), second days (d2), third days (d3), fifth days (d5).
  
  
  RESULTS
  (1) Cardiovascular function: In d3 and d5, heart rate (HR) and mean arterial pressure (MAP) were improved as compared to unlogged group (121, 119 vs. 138, 137; 71, 80 mmHg vs. 63, 62 mmHg, P < 0.05), with no statistical significance in arterial blood lactate concentration. (2) Oxygenation index (PaO₂/FiO₂) and arterial oxygen saturation (SaO₂) increased as compared to unlogged group, but did not reach statistical significance. (3) Blood urea nitrogen (BUN) and creatinine (Cr) were improved as compared with unlogged group from d1 (P < 0.05). (4) Inflammatory mediators did not show significant differences. (5) Twenty-eight days survival rate: logged group was 70.0%, unlogged group was 52.9%, but the difference was not statistically significant (P = 0.242).
  
  
  CONCLUSIONS
  CBP can improve circulatory function, oxygenation, and renal function in children with severe sepsis. No evidence was found that CBP could decrease the level of inflammatory mediators, improve critical score and 28 days survival rate.
