Trends in neonatal outcome with low Apgar scores.

Trends in incidence and neonatal outcome following low Apgar scores (1 min Apgar score < 6) were prospectively studied during the years (1981, 1983, 1986 and 1988. The incidence of birth asphyxia was 7.6% of live births during the study period; it was 5.8% in 1981, increased to highest of 8.9% in 1986 with slight reduction to 7.2% in 1988. Birth weight distribution of asphyxiated babies and 1 min Apgar score < 3 (severe asphyxia) remained unchanged. A significant decline in neonatal mortality with asphyxia was noted from 46.0% to 28.4% during 1981 and 1988 respectively. Aetiological factors for asphyxia could be identified in nearly 90% of infants during 1988, and all but 2 of 12 factors studied registered significant differences from control non-asphyxiated group.
