Long-term outcome of infants at the margin of viability.
The outcome of babies at extremely short gestational age (22 to 26 weeks) effects our clinical decisions regarding their care. We looked at survival and presence of disability at 25 +/- 11 months of age in 246 of these infants born at our hospital between 1992 and 1996 who were average weight for gestational age. Babies were evaluated in our follow up clinic by a pediatrician, and a physical therapist for cerebral palsy, blindness and deafness, and by a psychologist with the Bayley II. Chances for survival without disability exceeded 50% of live born infants at 25 weeks gestation or a birth weight of 700 to 800 grams. Chances for survival exceeded 50% of live born infants at 24 weeks gestation or a birth weight of 600 to 700 grams. Chances for intact survival reached 50% of survivors at 23 weeks gestation or a birth weight of 400 to 500 grams.
