Factors influencing nitrogen balance during total parenteral nutrition have been investigated in 38 malnourished patients studied for a cumulative period of 280 days. According to multiple regression analysis, nitrogen intake (0.213 +/- 0.004 g kg-1 day-1, mean +/- SD) proved to be the major determinant of a positive nitrogen balance (0.018 +/- 0.004 g kg-1 day-1), followed by non-protein energy intake (43.3 +/- 0.5 kcal kg-1 day-1). Total calorie intake to predicted basal energy expenditure and non protein calorie to nitrogen ratios appeared to have little significance on nitrogen balance, when corrected for the two former variables.
在38例营养不良患者中进行了为期280天的累计研究，以探讨全胃肠外营养期间影响氮平衡的因素。根据多元回归分析，氮摄入量（0.213±0.004 g·kg⁻¹·d⁻¹，均值±标准差）被证明是正氮平衡（0.018±0.004 g·kg⁻¹·d⁻¹）的主要决定因素，其次是非蛋白质能量摄入量（43.3±0.5 kcal·kg⁻¹·d⁻¹）。在校正了前两个变量后，总热量摄入与预测基础能量消耗的比值以及非蛋白质热量与氮的比值对氮平衡似乎没有显著意义。
