Abstract Objective To study the relationship between early parenteral nutrient intake and the development of bronchopulmonary dysplasia (BPD) in preterm infants with gestational age less than 32 weeks who could not receive enteral nutrition within one week after birth. Methods A retrospective study was conducted on preterm infants born between October 2017 and August 2022 with gestational age less than 32 weeks who were admitted to the Neonatal Intensive Care Unit in Children's Hospital of Soochow University within 24 hours after birth and relied solely on parenteral nutrition within the first week of life. The study population included 79 infants with BPD and 73 infants without BPD. Clinical data during hospitalization were compared between the two groups. Results The proportions of infants with weight loss of more than 10% after birth, extrauterine growth retardation, and parenteral nutrition-associated cholestasis in the BPD group were higher than in the non-BPD group (P<0.05). The time to regain birth weight, time to achieve full enteral feeding, and corrected gestational age at discharge were longer in the BPD group than in the non-BPD group. The Z-scores of physical growth at corrected gestational age of 36 weeks were lower in the BPD group than in the non-BPD group (P<0.05). The BPD group had a higher fluid intake and a lower calories intake in the first week than the non-BPD group (P<0.05). The starting dose and total amount of amino acids, glucose, and lipids in the first week were lower in the BPD group than in the non-BPD group (P<0.05). The BPD group had a higher glucose-to-lipid ratio on the third day and higher energy-to-nitrogen and glucose-to-lipid ratios on the seventh day after birth than the non-BPD group (P<0.05). Conclusions Preterm infants with BPD had lower intake of amino acids and lipids and a lower proportion of calories provided by amino acids and lipids in the first week of life, which suggests an association between early parenteral nutrition intake and the development of BPD.
