Fluid requirements in the preterm infant

Clin Perinatol. 1992 Mar;19(1):233-50.


Fluid requirements in the newborn are related to net fluid expenditures, normal changes in body water composition, and the integrity of renal regulatory functions. A variety of clinical conditions and therapeutic modalities also have an important effect on fluid requirements. Fluid therapy must be individualized to meet the specific needs of the infant. Appropriate fluid therapy will facilitate physiologic changes of body water composition and decrease neonatal morbidity.
