To characterize the baseline nutritional changes occurring in healthy baboons receiving an acute lung injury, we prospectively evaluated serial nutritional changes in eight adult baboons that received oleic acid (0.08 mL/kg) and then required mechanical ventilation for a period of 8 d. The animals were given hypocaloric feeding. Nutritional assessment included the measurement of changes in muscle mass and changes in visceral protein concentration and plasma lipids. Both serum protein and albumin concentrations decreased for 3 d after mechanical ventilation began but then remained stable. The animals exhibited a marked increase in bronchoalveolar lavage fluid (BALF) protein concentrations after receiving oleic acid. We conclude that previously healthy baboons receiving only dextrose infusion during mechanical ventilation have marked decreases in serum albumin occurring after the lung injury. Decreases in albumin occur very early and may represent pooling of albumin in the lung after the oleic acid injury.
