To evaluate the temporal pattern of urea excretion in chair-adapted primates (Macaque fascicularis) on continuous total parenteral nutrition (TPN), two groups of five animals were studied. Group I received continuous TPN (75 glucose kcal; 0.56 g nitrogen; and 100 ml fluid per kg per day) while Group II received a single morning isonitrogenous oral meal along with a continuous isovolemic intravenous infusion of 0.45% saline. Urine was collected hourly in group I for 2 days and every 4 hr in group II for 5 days and analyzed for urea content. Time series analysis revealed no periodicity of urea excretion in either group. Six animals were then studied for a total of 46 TPN days to define the relationship between the urea content of a single 3-hr morning urine aliquot and its respective content in a 24-hr collection. A significant linear relationship was found (r = +0.76, p less than 0.01). However, using this relationship, a reasonable estimate (+20%) of measured 24-hr urea output was achieved only 50% of the time using a single 3-hr urea output. Chair-adapted primates maintained on continuous TPN or a single oral meal with continuous saline infusion do not exhibit a periodic pattern of urea excretion. The variability in 3-hr urinary urea output in the chaired primate on continuous TPN does not consistently permit accurate estimation of the coincident 24-hr urinary urea output.
