Early complications in virtually all body systems occur as a result of difficulties in maintaining homeostasis
A preterm infant has difficulties with fetal to neonatal transition and maintaining homeostasis i.e. temperature control, euglycemia, fluid and electrolyte balance. Preterm infants usually exhibit significant jaundice and profound anemia. Full enteral nutrition is a problem even in healthy a near-term infant.
