Abstract
The emergence of new obstetrical and neonatal technologies, as well as more aggressive clinical management, has significantly improved the survival of extremely low birth weight infants. This development has heightened concerns about the limits of viability. ELBW infants, weighing less than 1,000 grams and no larger than the palm of one's hand, are often described as of late twentieth century technology. Improved survivability of ELBW infants has provided opportunities for long-term follow-up. Information on their physical and emotional development contributes to developing standards of practice regarding their care
