Vitamin D Testing

Birth History

January 2009

A brief history of the premature infant is that the infant was born via C-section performed on the mother in whom the ultrasound showed abnormal umbilical blood flow and the intrauterine growth was retarded.

The premature infant had Apgar scores of 6 and 7. The infant was intubated and given Survanta, which is a lung surfactant, to help with breathing. The infant was also quickly transferred to a neonatal intensive care unit for medical management.
