Breast feeding and infant nutrition.

Breast feeding is a management problem requiring knowledge of the physiology of lactation, maternal and infant nutritional requirements, and specifics such as drugs which enter the milk. The job of the physician is to allay anxiety; this helps establish the let-down reflex and increases milk production. "Caking," mastitis and even abscesses are not indications for weaning. Rest, warm compresses and frequent nursing are indicated. Breast-fed infants have less tendency to obesity than those who are bottle-fed. Early solid foods in the diet are not needed.

Acetaminophen poisoning.

A case of suspected acetaminophen poisoning is reported in a child who ingested 19 gm of acetaminophen over a seven-day period. She exhibited evidence of severe renal and hepatic damage which resolved with supportive therapy. Serum levels of acetaminophen were not in the toxic range; hence, proof of the etiology was not possible. It is probable that a delay in suspecting acetaminophen toxicity allowed time for the serum acetaminophen level to return to normal. Acetaminophen is a safe drug when used properly, but overdosage can cause severe toxicity. With increased use in this country, increasing episodes of overdosages should be anticipated. Blood levels should be obtained early in acutely ill patients when acetaminophen toxicity is suspected.

Neonatal resuscitation.

A variety of common situations result in asphyxia of the newborn. The infant may be born in secondary or terminal asphyxia. The infant at greatest risk of neurologic sequelae is the low birth weight infant with a low five-minute Apgar score. Personnel must be trained and the delivery room must be properly equipped for successful resuscitation. For example, a radiant warmer is essential. Meconiumstained infants require special care. Meconium must be removed from the airway. The list of postasphyxial complications is formidable.

Thermoregulation of the newborn.

The classic modes of heat loss affecting the newborn are conduction, convection, radiation and evaporation. The disproportionate ratio of surface area to body weight (SA/BW) of the premature infant is the basis of inefficient heat conservation, combined with a blunted metabolic response. Hypothermia leads to hypoxemia, acidosis, hypoglycemia, kernicterus and other lethal complications. Mistakes are common. Attention to minute details is required for stabilization of body temperature at the "neutral temperature zone" in delivery room, nursery and in transport.
