本文测定了三种氨基酸混合液的pH值和可滴定酸度，并与八种常用的静脉注射液进行了比较。虽然两组的平均pH值相似，但三种氨基酸混合物的平均可滴定酸度（30.54 mEq/L）明显高于八种静脉注射溶液（0.13 mEq/L）。氨基酸混合物的高可滴定酸度可能是高营养婴儿发生代谢性酸中毒的一个主要因素。8种静脉注射溶液的可滴定酸度与水空白溶液（0.16 mEq/L）无显著差异。
The pH and titratable acidity of three amino acid mixtures used in hyperalimentation were determined and compared with those of eight common intravenous solutions. Although the mean pH of the two groups was similar, the mean titratable acidity of the three amino acid mixtures (30.54 mEq/liter) was markedly higher than that of the eight intravenous solutions (0.13 mEq/liter). The high titratable acidity of the amino acid mixtures could be a major factor in the development of metabolic acidosis in hyperalimented infants. The titratable acidity of the eight intravenous solutions did not differ significantly from that of water blanks (0.16 mEq/liter).
