Brain injury in the premature infant--current concepts of pathogenesis and prevention.

Brain injury in the premature infant and, particularly, the prevention of that injury is an enormous problem. With modern neonatal intensive care, approximately 85% of very low birth weight infants survive, and of these survivals, approximately 5-15% exhibit major spastic motor deficit, grouped under the rubric, 'cerebral palsy', and an additional 25-50% exhibit less prominent developmental disabilities, particularly school failure.
