| Abstract |
Purpose
: By rapid development of neonatal intensive care from 1960, we are able to
expect the long survival of the very low birth weight infants. But, there were high risk of poor growth, neurodevelopmental delay, deafness, and blindness in very low birth weight infants. So, it is important to follow-up after discharge. We try to compare normal term infants with very low birth weight infants by evaluating growth and neurodevelopmental outcome from living very low birth weight infants to corrected 2 years age.
Methods
: This study was performed on 55 very low birth weight infants with
corrected age 6 months to 24 months who were admitted to the neonatal intensive care
unit of Presbyterian Medical Center from August 1991 to December 1993 and 61 normal
term infants with age 6 months to 24 months who had been born in Presbyterian
Medical Center. We compared very low birth weight infants with normal term infants
about growth and neurodevelopmental outcome at corrected age 6, 12, 18, 24 months.
Weight, height and head circumference were measured. Developmental testing was
performed using the BSID-Ⅱ(Bayley scales of infant development, Ⅱ). BSID-Ⅱ test
provide Mental DevelopmentIndex (MDI) and Psychomotor Development Index(PDI).
Motor handicap was graded as mild, moderate, or severe cerebral palsy. Sensorineural
impairments were measured.
Results
: 1) Very low birth weight infants were low in weight, height and head circumference compared with normal term infants to corrected 2 years age. But, most cases were above 10 percentile
2) Very low birth weight infants were in low in BSID-Ⅱ's MDI(93.5±15.8) and
PDI(91.3±17.9) compared with normal term infants. But, 76% of them were within
normal range in MDI, 77% of them in PDI.
3) Seven patients of 55 very low birth weight infants had severe neurodevelopmental
handicaps and three patients had severe cerebral palsy.
Conclusion
: We concluded that very low birth weight infants had significantly
lower growth and BSID-Ⅱ than normal term infants, but majority of very low birth
weight infants belong to normal range. |
