Abstract
INTRODUCTION: Decreased pediatric survival has been reported with long-duration (>4 weeks) continuous renal replacement therapy (CRRT), though the practice has not been well-described. METHODS: Retrospective chart review in a children's hospital of all patients treated with CRRT over 2 years (2003-4), including those who underwent long (group 1) and shorter duration (group 2) therapy. RESULTS: We identified 39 patients: median age was 6 years (range: 0.3-23; 7 were infants), median PRISM III score was 16 (range: 4-35), and the most frequent primary diagnosis was a stem cell transplant (in 12 out of 39). At continuous renal replacement therapy initiation, almost all patients (38 out of 39) had multiorgan dysfunction syndrome, most (35 out of 39) were being treated with at least one inotrope or vasopressor, and median fluid overload was 18% (range: 1-43%). Survival was poor (38%). Groups 1 (n = 7) and 2 (n = 32) had similar age (p = 0.44), PRISM III score (p = 0.61), and stem cell transplant diagnosis (p = 0.65). At CRRT initiation, the incidence of multiorgan dysfunction syndrome (p=0.18), inotrope or vasopressor treatment (p = 0.56), and fluid overload severity (p = 0.71) were similar. Those in group 1 had a longer mean CRRT as well as persistent cardiovascular dysfunction limiting the utility of intermittent dialysis. Survival was similar between groups (p = 1). CONCLUSIONS: Critically-ill patients treated with long and shorter duration CRRT had a similar survival rate.
