UnlabelledAcute renal insufficiency accounts for high mortality in paediatric intensive care patients, particularly in infants. Peritoneal dialysis, usually carried out with dialysate volumes of >20 ml/kg body weight, increases pulmonary artery pressure, which may compromise myocardial function in critical illness. In this paper we report our experiences with the use of lower dialysate volumes in the treatment of critically ill children with renal impairments. We suggest that low-volume peritoneal dialysis is able to achieve adequate ultrafiltration, which relieves overhydration in ventilated and haemodynamically compromised children. A total of 116 paediatric intensive care patients treated between 1992 and 2000 was the subject of this investigation. Diagnosis, indication for dialysis, arterial and central venous pressure, blood gases, creatinine, blood urea nitrogen, urinary output at installation, ultrafiltration, fluid balance, duration and complications during dialysis as well as survival were investigated. The overall mortality was 53%. The respective diagnoses and mortality rates were as follows: 65% of the patients suffered from cardiac diseases (54% mortality), 7% from renal diseases (13%) and 28% from multi-organ system failure (62%). Low-volume peritoneal dialysis was started at evidence of total body fluid overload with inadequate urinary output and resulted in a mean ultrafiltration of 2.8 ml/kg body weight per h. A negative fluid balance was achieved in 53% of patients, mainly in those suffering from hypervolaemia and minor oliguria. None of the complications resulted in death.Conclusionearly installation of low-volume peritoneal dialysis offers a safe and adequate ultrafiltration procedure for paediatric critical care patients suffering from minor oliguria and fluid overload.
