[Incidence of congenital malformations and neonatal mortality in children born at the Regional Hospital in Brzeziny in years 1990-2001].
The aim of the study was to estimate the incidence of congenital malformations and neonatal mortality rate in children born in our hospital from 1990 to 2001, taking into account the effects of low birth weight and premature delivery. We investigated medical documentation of 5496 children born during the analyzed period. Presence of major and minor malformations and survival through the neonatal period were determined for each subject. Among newborns with low birth weight 8.3% were born with congenital malformations, among those born preterm--12.1%. The major malformations were 3 times more often in children with low birth weight and 4 times more often in children born prematurely. In our cohort the mortality of 0.2% was observed. Congenital defects, followed by the complications of preterm delivery, were the predominant causes of natal death. Deaths due to congenital defects occurred twice as often as the deaths caused by prematurity complications. The congenital malformations mortality in newborns with congenital malformations reached 4.8%. The majority of congenital defects deaths were caused by central nervous system defects, chromosomal aberrations and multiple congenital malformations.
