Intrapartum amnioinfusion for meconium-stained amniotic fluid

Aim: The purpose of this study was to assess whether the intrapartum amnioinfusion (AI) in the presence of meconium-stained amniotic fluid (MSAF) influence the rate of cesarean section and perinatal outcome. Material and methods: The investigated group consisted of 405 pregnant women in labor with meconium-stained amniotic fluid: 163 had performed AI, and 242 constituted a control group (without AI). The way of delivery, the occurrence of fetal distress symptoms in cardiotocography, fetal outcome based on Apgar scoring and umbilical artery acidemia, the presence of clinical and radiological symptoms of meconium aspiration syndrome and respiratory disorders in neonates were analyzed. Results: The performance of AI influenced neither the occurrence of the signs of fetal distress nor the rate of cesarean section indicated by fetal distress. There was no difference in the incidence of low Apgar score (< 5) at 1 and at 5 min. and umbilical acidemia. The frequency of meconium aspiration syndrome and neonate’s dyspnea were comparable. There were no major complications related to AI. Conclusions: The prophylactic intrapartum AI for meconium stained amniotic fluid does not decrease the incidence of fetal distress or the rate of cesarean section and it does not improve neonatal outcome.
