title: [The epidemiology of meconium stained amniotic fluid on hospital basis].
abstract: OBJECTIVE
  To explore the epidemiology of meconium stained amniotic fluid pero-delivery.
  
  
  METHODS
  6,206 one-fetal delivery cases were divided into meconium stained amniotic fluid and normal amniotic fluid groups. Statistics were analysed on two groups using Cohort study.
  
  
  RESULTS
  Incidence of meconium stained amniotic fluid was 16.4%. There was no significant difference on maternal medical complication between two groups. The percentage of parity, gestational week > or = 42 weeks and big birth weight were higher in meconium stained amniotic fluid group than that in normal amniotic fluid group (P < 0.001). The average Apgar score in meconium stained amniotic fluid group was lower than that in normal amniotic fluid group (P = 0.001). The percentage of stillbirth, low birth weight and transferred newborn care unit in meconium stained amniotic fluid group were higher than that in normal amniotic fluid group (P < 0.001).
  
  
  CONCLUSIONS
  The relative factors on meconium stained amniotic fluid were maternal parity, gestational weeks > or = 42 weeks and big birth weight. No correlation between meconium stained amniotic fluid and maternal medical complication. Morbidity of newborn baby was higher in meconium stained amniotic fluid. Meconium stained amniotic fluid is a important clinical factor on evaluating pregnancy outcome.
