Prophylactic methylxanthine for preventing of apnea in preterm infants.

Recurrent apnea is common in preterm infants, particularly at very early gestational ages. These episodes of loss of effective breathing can lead to hypoxemia and bradycardia which may be severe enough to require resuscitation including use of positive pressure ventilation. In infants with apnea, methylxanthines have been successful as treatment to prevent further episodes. It is possible that prophylactic therapy, given to all very preterm infants from soon after birth, might prevent apnea and its associated hypoxemia and bradycardia.
