4、nt Therapy in the PICU: Pediatric Outcome Literature,Few pediatric studies (all single center) use a severity of illness measure to evaluate outcomes in pCRRT: Lane noted that mortality was greater after bone marrow transplant who had 10% fluid overload at the time of HD initiation Smoyer2 found hig

Faragson3 found PRISM to be a poor outcome predictor in patients treated with HD Zobel4 demonstrated that children who received CRRT with worse illness severity by PRISM score had increased mortality Did not stratify by modality,1.

7、 who receive CRRT are more ill,Maxvold NJ et al: Am J Kidney Dis 1997 Nov;30(5 Suppl 4):S84-8,Pediatric ARF: IHD and CRRT,Bunchman TE et al: Ped Neph 16:1067-1071, 2001,Pediatric ARF: Disease and Survival,Bunchman TE et al: Ped Neph 16:1067-1071, 2001,Pediatric ARF: Modality and Survival,% Survival,

The mean PRISM score at admission to the Texas Childrens Hos
9、pital PICU is 14.,RESULTS,22 pt (12 male/10 female) received 23 courses (3028 hrs) of CVVH (n=10) or CVVHD (n=12) over study period. Overall survival was 41% (9/22). Survival in septic patients was 45% (5/11). PRISM scores at ICU admission and CVVH initiation were 13.5 +/- 5.7 and 15.7 +/- 9.0, resp

11、in the PICU Pediatric Literature,Survival curve demonstrates that nearly 75% of deaths occurred less than 25 days into the ICU course,Goldstein SL et al: Pediatrics 2001 Jun;107(6):1309-12,Renal Replacement Therapy in the PICU Pediatric Literature,Lesser % FO at CVVH (D) initiation was associated with improved outcome (p=0.03) Lesser % FO at CVVH (D) initiation was also associated with improved outcome when sample was adjusted for severity of illness (p=0.03; multiple regression analysis),
