Tidal dialysis urea [NU] and total nitrogen [NT] clearances were obtained from nine patients, weighing 15-79 kg. Clearances normalized to a 70 kg body weight [nClr in ml/min/70 kg] increased with dialysate flow normalized to body weight [nFlow in ml/hr/kg]. The nClr [NU] = 6.862 + 0.352 x nFlow (r = 0.641, p less than or equal to 0.01). The nClr [NT] = 15.815 + 0.431 x nFlow (r = 0.460, p less than or equal to 0.01). Dialysate non-urea nitrogen [NT - NU] losses were 44.63 +/- 2.79 mg/kg daily, and these were altered minimally by the dialysate flow rate.

UI	MeSH Term	Description	Entries
D010531	Peritoneal Dialysis, Continuous Ambulatory	Portable peritoneal dialysis using the continuous (24 hours a day, 7 days a week) presence of peritoneal dialysis solution in the peritoneal cavity except for periods of drainage and instillation of fresh solution.	CAPD,Continuous Ambulatory Peritoneal Dialysis
D001806	Blood Urea Nitrogen	The urea concentration of the blood stated in terms of nitrogen content. Serum (plasma) urea nitrogen is approximately 12% higher than blood urea nitrogen concentration because of the greater protein content of red blood cells. Increases in blood or serum urea nitrogen are referred to as azotemia and may have prerenal, renal, or postrenal causes.
