title: [Preterm deliveries of extremely low birth babies--analysis of the course of pregnancy, labour and neonatal outcome].
abstract: OBJECTIVE
  Preterm delivery of baby with extremely low birth weight (ELBW) is an important problem in contemporary perinatology and a major reason of perinatal mortality. A great development of neonatal intensive care that has occurred over the last few years has resulted in the decrease of perinatal mortality rate. The aim of the study is to analyse the course of pregnancy, labour and neonatal outcome in the group of patients who delivered ELBW children.
  
  
  METHODS
  In 1st Obstetric and Gynaecology Department Clinic of Medical University of Warsaw, 6982 deliveries were conducted from 1996 to 2000. Among them there were 589 preterm ones. As a result 44 women delivered ELBW children. These 44 deliveries were divided into three groups according to the reasons: Idiopathic preterm contractility-24 patients PROM with intrauterine infection or threatening infection-14 Induction of delivery because of lethal foetal defects and direct foetal distress-6.
  
  
  RESULTS
  The most common reasons for deliveries of ELBW children were hypertension and ascending infections.
  
  
  CONCLUSIONS
  A great number of mothers who delivered ELBW children had low socioeconomic status. In most cases pregnancy was unplanned and body mass index of the mothers was below 19. Almost all these newborns were severely depressed and delivery was often complicated. It is important to conduct labour in a careful way to avoid tissue injuries.
