    Abstract:
    BACKGROUND: This article reports demographic characteristics and intensive care unit survival for 344 patients from the Prospective Pediatric Continuous Renal Replacement Therapy (ppCRRT) Registry, a voluntary multicenter observational network. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS: Ages were newborn to 25 yr, 58% were male, and weights were 1.3 to 160 kg. Patients spent a median of 2 d in the intensive care unit before CRRT (range 0 to 135). At CRRT initiation, 48% received diuretics and 66% received vasoactive drugs. Mean blood flow was 97.9 ml/min (range 10 to 350 ml/min; median 100 ml/min); mean blood flow per body weight was 5 ml/min per kg (range 0.6 to 53.6 ml/min per kg; median 4.1 ml/min per kg). Days on CRRT were <1 to 83 (mean 9.1; median 6). A total of 56% of circuits had citrate anticoagulation, 37% had heparin, and 7% had no anticoagulation. RESULTS: Overall survival was 58%; survival differed across participating centers. Survival was lowest (51%) when CRRT was started for combined fluid overload and electrolyte imbalance. There was better survival in patients with principal diagnoses of drug intoxication (100%), renal disease (84%), tumor lysis syndrome (83%), and inborn errors of metabolism (73%); survival was lowest in liver disease/transplant (31%), pulmonary disease/transplant (45%), and bone marrow transplant (45%). Overall survival was better for children who weighed >10 kg (63 versus 43%; P = 0.001) and for those who were older than 1 yr (62 versus 44%; P = 0.007). CONCLUSIONS: CRRT can be used successfully for a wide range of critically ill children. Survival is best for those who have acute, specific abnormalities and lack multiple organ involvement; sicker patients with selected diagnoses may have lower survival. Center differences might suggest opportunities to define best practices with future study.
