Care of the premature infant: Part I. Monitoring growth and development

When monitoring growth and development in the premature infant, physicians should make adjustments for the estimated due date. With minor exceptions, administration of immunizations is based on the chronologic age. Administration of hepatitis B vaccine should be delayed until the infant weighs 2,000 g (4 lb, 5 oz). Administration of influenza vaccine should be considered in infants with chronic medical problems, and the pneumococcal vaccine may be beneficial at age two in children 1 with chronic problems, especially pulmonary disease. Premature infants should also be monitored to assure appropriate nutrition. Breast-fed infants should probably receive vitamin supplements during the first year. Supplemental iron should be initiated at two weeks to two months after birth and continued for 12 to 15 months. Office care includes screening for problems that occur more frequently in premature infants, especially vision and hearing problems. Because many of these infants require care from multiple medical disciplines, coordination of care is another important role for the family physician. The goals of this care are to promote normal growth and development and minimize morbidity and mortality.
