The Maternal Fetal Center works in tandem with obstetrical providers and birthing centers to optimize the health of the mothers and babies. Children’s Hospital operates Level II satellite neonatal intensive care units at birthing centers in Merced, Fresno and Hanford, and is planning to expand our unit at Saint Agnes Medical Center to a community Level III NICU. This much-needed upgrade will allow more babies delivered at Saint Agnes who require a higher level of care to stay in the same hospital as their mothers.
Our perinatologists regularly address medical challenges pregnant women may face and offer encouragement, education, and hope while caring for patients and families in an atmosphere of kindness, dignity and respect. No other program in Central California can provide the depth and breadth of services available through the Maternal Fetal Center at Children’s Hospital Central California.
