title: Continuous renal replacement therapy and plasma exchange in newborns and infants.
abstract: The objective of our study was to present our experience in the treatment of small children with continuous renal replacement therapy (CRRT) and plasma exchange (PE). From March 1986 to April 2000, 21 critically ill children (14 newborns and 7 infants) with acute renal failure (ARF) and multiple organ failure were treated with CRRT and PE. In the newborn group, there were 8 males and 6 females, age 15.7 +/- 11.7 days, with body weights of 3,348 +/- 585 g. In the infant group, there were 4 males and 3 females, age 118 +/- 67 days, with body weights 5,186 +/- 734 g. The indications for the beginning of CRRT and/or PE were ARF with anuria and hyperhydration (17 patients), azotemia and anuria (1 patient), hemolytic uremic syndrome (1 patient), and hyperammonemia (2 patients). In all patients, peritoneal dialysis was considered inappropriate. PE and CRRT monitors were used, double lumen 5 Fr and 7 Fr hemodialysis catheters were the vascular access, low dose heparin and prostacyclin were anticoagulants, and lactate or bicarbonate buffered replacement solutions were used predilutionally. Side events were clotting within the extracorporeal circuit, catheter malfunction, serious hypotension (6 patients), and pulmonary edema (1 patient). Ten of 21 patients (47.6%) recovered renal function and 9 of 21 patients (42.9%) survived. Survivors had fewer failing organs (3.6 +/- 0.5) than nonsurvivors (4.8 +/- 0.9) (p = 0.0008). Pump driven CRRT and PE were feasible, efficient, and safe procedures in newborns and infants. Without CRRT, it is uncertain whether any of our patients would have the chance to survive.
