text: [The significance of meconium-containing amniotic fluid at the onset of labor following a normal pregnancy].
  The delivery process of 218 gravids admitted after a normal course of pregnancy with meconium containing amniotic fluid are analysed. The higher operative frequency (25,2%) in comparison with the test group (10,9%) and the fact that in 4 fetuses the pH value on admission was under 7,20 confirm the recommendation to make obligatory the admission amnioscopy of all gravids at the beginning of birth. This practice involves continuous medical shift work. The perinatal mortality of the analysed deliveries was 0,46%.
