[Analysis of very underweight newborn infants (less than 1,500 g) 1972-1982. Epidemiologic aspects, labor presentation, position and adjustment, method of delivery and mortality].

Infants with a very low birthweight (less than 1500 g) have a fundamental influence on perinatal mortality and mortality of babies up to one year also nowadays. The epidemiological role of different signs of risk in the context of the birth of these children is presented. The total mortality of the infants with a very low birthweight (less than 1500 g) was 64,4%. Usually there were combinations of factors, which caused the death of the infants. Complications of secundinae, immaturity and malformations were the substantial factors of lethality of the stillbirths. At the mortality of babies there were intracranial bleedings and immaturity (less than 1000 g, less than 28 completed weeks of pregnancy) in the foreground of the causes of death.
