title: Common issues in the care of sick neonates.
abstract: Newborn infants may be transferred to a special care nursery because of conditions such as prematurity (gestation less than 37 weeks), prolonged resuscitation, respiratory distress, cyanosis, and jaundice, and for evaluation of neonatal sepsis. Newborn infants' core temperature should be kept above 36.4 degrees C (97.5 degrees F). Nutritional requirements are usually 100 to 120 kcal per kg per day to achieve an average weight gain of 150 to 200 g (5 to 7 oz) per week. Standard infant formulas containing 20 kcal per mL and maternal breast milk may be inadequate for premature infants, who require special formulas or fortifiers that provide a higher calorie content (up to 24 kcal per mL). Intravenous fluids should be given when infants are not being fed enterally, such as those with tachypnea greater than 60 breaths per minute. Hypoglycemia can be asymptomatic in large-for-gestational-age infants and infants of mothers who have diabetes. A hyperoxia test can be used to differentiate between pulmonary and cardiac causes of hypoxemia. The potential for neonatal sepsis increases with the presence of risk factors such as prolonged rupture of membranes and maternal colonization with group B streptococcus. Jaundice, especially on the first day of life, should be evaluated and treated. If the infant does not progressively improve in the special care nursery, transfer to a tertiary care unit may be necessary.
