[Prevention of meconium aspiration]

Abstract

The aim of the study was to determine the risk of meconium aspiration by perinatal and obstetric characteristics and to give directions for prophylactic management. 67 infants with meconium-stained amniotic fluid received intrapartum pharyngeal suctioning and postpartum direct laryngoscopy and suctioning of the trachea. The risk for the presence of meconium in airways is increased if meconium is visible at the vocal cords (p less than 0.01), amniotic fluid showing thick meconium staining (p less than 0.001) Fischer-score being below 7 points (p less than 0.05) or Apgar-score being below 8 points(p less than 0.05). Immediately after delivery inspection of the vocal cords is necessary by direct laryngoscopy. Suctioning of the trachea under direct vision after delivery should be done if meconium is visualized at the vocal cords. Meticulous care of the fetus exposed to a meconium containing amniotic fluid environment and the avoidance of acute fetal stress may decrease the incidence of meconium aspiration.
