Medical problems associated with prematurity are frequently complex, and a multidisciplinary approach is often required. Some common problems include the following: (1) anemia, which can be reduced by iron supplementation, (2) cerebral palsy or mental retardation as a result of intraventricular hemorrhage or periventricular leukomalacia, (3) respiratory problems, including bronchopulmonary dysplasia and apnea, (4) visual problems, such as those associated with retinopathy of prematurity, (5) gastroesophageal reflux and (6) surgical problems, including inguinal or umbilical hernia and cryptorchidism. Monitoring of growth and development includes recording the infant's head circumference, weight and length on a growth chart for premature infants. Nutritional status should be assessed at each visit, watching for hyperosmolar problems in infants receiving high-calorie formulas. Consultation with other specialists may be required if abnormalities are identified during follow-up care in the office.
