Five different arteriovenous renal replacement systems were used to treat 23 critically ill oliguric or anuric children. Slow continuous ultrafiltration (SCU) was carried out for 8 patient days, continuous arteriovenous haemofiltration (CAVH) for 40, suction-supported CAVH for 56, continuous or intermittent arteriovenous haemodiafiltration (AVHDF) for 3, and continuous arteriovenous haemodialysis (CAVHD) for 24 days. SCU allowed excellent control of fluid overload in 4 patients within 47 +/- 17 h. Urea clearances ranged from 5.6 +/- 2.1 ml/min per m2 (spontaneous CAVH) to 15.3 +/- 3.7 ml/min per m2 (CAVHD) and enabled good control of azotaemia. Ultrafiltration rates of the different filters ranged from 1.6 +/- 0.3 to 11.5 +/- 2.4 ml/min per m2. The only serious complication was a femoral artery thrombosis in a 1.5-year-old boy. Minor side-effects were local bleeding at the entrance site of the arterial catheter and transient hypotension during suction-supported CAVH. Of 23 patients, 8 died because of progressive multiple organ system failure, a mortality of 35%.

UI	MeSH Term	Description	Entries
D007022	Hypotension	Abnormally low BLOOD PRESSURE that can result in inadequate blood flow to the brain and other vital organs. Common symptom is DIZZINESS but greater negative impacts on the body occur when there is prolonged depravation of oxygen and nutrients.

D013396	Suction	The removal of secretions, gas or fluid from hollow or tubular organs or cavities by means of a tube and a device that acts on negative pressure.

D013997	Time Factors	Elements of limited time intervals, contributing to particular results or situations.	Time Series,Factor, Time,Time Factor
D014462	Ultrafiltration	The separation of particles from a suspension by passage through a filter with very fine pores. In ultrafiltration the separation is accomplished by convective transport; in DIALYSIS separation relies instead upon differential diffusion. Ultrafiltration occurs naturally and is a laboratory procedure. Artificial ultrafiltration of the blood is referred to as HEMOFILTRATION or HEMODIAFILTRATION (if combined with HEMODIALYSIS).
D058186	Acute Kidney Injury	Abrupt reduction in kidney function. Acute kidney injury encompasses the entire spectrum of the syndrome including acute kidney failure; ACUTE KIDNEY TUBULAR NECROSIS; and other less severe conditions.
