Objective:
To study the clinical features, etiology, treatment, and prognosis of neonatal chylous effusions.
Methods:
A retrospective analysis was performed for the clinical data of 21 neonates with chylous effusions.
Results:
Among these 21 neonates, 13 had chylothorax, 2 had chyloperitoneum, 2 had chylopericardium, and 4 had chylous polyserositis. Five neonates with congenital chylous effusions were enrolled as the congenital group, which mostly occurred in the fetal period, and symptoms were observed shortly after birth. Sixteen neonates with acquired chylous effusions were enrolled as the acquired group, and the symptoms mainly appeared within 1 week after central venous catheterization (in 14 neonates) or appeared together with sepsis (in 2 neonates). Compared with the acquired group, the congenital group had significantly higher specific gravity, white blood cell count, monocyte percentage, and albumin level in effusions (P<0.05) and significantly lower levels of glucose and triglyceride (P<0.05). Central venous catheterization-induced chylous effusions were mainly associated with inappropriate position, displacement damage, and hypertonicity. Conservative treatment was the main treatment method for the neonates with chylous effusions (in 20 children), with a response rate of 85%. Compared with the acquired group, the congenital group had a significant higher proportion of neonates receiving special formula feeding, a significantly lower proportion of neonates with extubation, and a significantly longer time to the absorption of effusions (P<0.05).
Conclusions:
The time to the occurrence of symptoms and clinical manifestations vary with disease etiology and location in neonates with chylous effusions. Neonates with acquired chylous effusions may experience hypertonic solution effusion due to vascular injury. Conservative treatment has a marked clinical effect on neonatal chylous effusions. It appears to be more difficult to treat neonates with congenital chylous effusions than those with acquired chylous effusion.

A pleural effusion is the abnormal collection of fluid between the parietal and visceral pleura layers of tissue that form the lining of the lungs and chest cavity. It can occur independently or due to surrounding parenchymal diseases, such as infection, malignancy, or inflammatory conditions.
