Except for the hyperinsulinism associated with the infant of a diabetic mother (accounting for about 5 percent of NICU admissions annually), pancreatic disorders of the newborn are rare. Congenital anomalies (such as annular pancreas) and endocrine disorders (such as hyperinsulinism of nesidioblastosis or hyperglycemia of neonatal diabetes mellitus) present many challenges to the personnel caring for these infants and their families. The potential mortality and morbidity of these disorders make it imperative for nurses and nurse practitioners working with infants to recognize and understand pancreatic dysfunction so that appropriate and timely intervention can prevent complications of brain injury and developmental delay. The home care needs of these infants and the extensive teaching needs of their parents require skilled nursing care to ensure a safe discharge.
