title: [The incidence of serious complications in neonates with birth weight < 1,500 g in the Czech Republic (in the period 2000-2002)].
abstract: OBJECTIVE
  To analyse the incidence of serious complications in neonates with birth weight lower than 1,500 g in the Czech Republic in the years 2000-2002.
  
  
  METHODS
  A retrospective epidemiological study.
  
  
  METHODS
  Frequency analysis of the data from the National Register of Neonates, administrated by the Institute of Health Information and Statistics of the Czech Republic.
  
  
  RESULTS
  The incidence of PIVH of level III-IV in neonates with weight of up to 1,500 g in the Czech Republic in the years 2000-2002 was 6.8-10.3%; the incidence of cPVL reached 6.4-7.6%; the incidence of ROP of level III and of a higher level was 6.6-7.9% and the incidence of NEC was between 4.3 and 5.7% of all live births. Among the surviving neonates, the percentages of those who did not have any of the PIVH, ROP, HIE or meningitis diagnoses in the reference period were as follows (according to their birth weights): 500-749g 50-63.8%; 750-999 g 69.7-74.8%; 1,000-1,499 g 86.8-91.4%; 1,500-1,999g 98-98.2%; 2,000-2,499 g 99.4-99.5%; and in the group with weight above 2,500g, the percentage was 99.9%.
  
  
  CONCLUSIONS
  The incidence of serious complications in neonates with birth weight of up to 1,500 g in the Czech Republic in the years 2000-2002 was comparable with the data stated in the literature, except for cPVL, the incidence of which was higher in the Czech Republic. The proportion of neonates, who were released and did not have any of the complications, which pose a risk to normal neurosensory development, does not virtually change for birth weights higher than 1,500 g and reaches 98 and more percent. However, among the surviving neonates with birth weight of up to 750, their proportion is mere 50-64%.
