Tidal peritoneal dialysis. Urea and total nitrogen losses.
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.
