title: Energy expenditure in premature newborns with bronchopulmonary dysplasia.
abstract: Five premature newborns (birth weight, mean +/- SD, 960 +/- 145 g; gestational age 28 +/- 1 weeks) with bronchopulmonary dysplasia (BPD) according to the criteria of Bancalari, and 6 controls (birth weight 1,320 +/- 210 g; gestational age 30 +/- 2 weeks) were studied for energy expenditure (EE) by indirect calorimetry. The measurement of total EE was performed when the intake of the infants in both groups was the same and when the respiratory condition had stabilized (control group: postnatal age 31 +/- 6 days, 1,950 +/- 200 g; BPD group: postnatal age 105 +/- 45, postnatal weight 2,440 +/- 380). The BPD group had a higher VO2 (11.15 vs. 8.04 ml/kg/min, p less than 0.01), VCO2 (9.13 vs. 7.74 ml/kg/min, p less than 0.02) and total EE (76 vs. 61 kcal/kg/day, p less than 0.02). The highest values were encountered in the 3 more severely ill infants: mean VO2 11.03 ml/kg/min, mean EE 82 kcal/kg/min. In these cases, administration of medium chain triglycerides limits the increase in VCO2 and lowers the respiratory quotient (0.87 vs. 0.96 in controls.
