title: [Analysis of the postnatal condition and mortality of neonates with extremely low birth weight].
abstract: OBJECTIVE
  The aim of this study was to analyze the postnatal condition and mortality of neonates with extremely low birth weight.
  
  
  METHODS
  The study group consisted of 35 neonates delivered in the 1st Dept of Ob/Gyn. Medical University of Warsaw in the period of 1996-2000. The group was divided into two classes depending on the birth weight. There were newborns weighted 500-750 g in the first class and 751-1000 g in the second one. Newborns condition in the 1st minute of life was assessed with Apgar score. The rate of mortality up to the 7th day of life as well as the causes of deaths was analyzed.
  
  
  CONCLUSIONS
  Postnatal mortality rate of premature newborns extremely low birth weight is still very high, especially in case of newborns below 750 g. Respiratory distress syndrome and intracranial hemorrhage are the most common causes of demise of those newborns.
