In utero distal pulmonary meconium aspiration.

We have recently had eight cases of severe meconium aspiration syndrome which occurred despite clearing of the posterior pharynx of meconium after delivery of the head but before delivery of the body. Seven of the eight cases had documented fetal distress before delivery. Two stillborns with meconium aspiration are presented and illustrate that electronic fetal monitoring and aggressive obstetric intervention should be coupled with the suctioning technic to prevent significant mortality and morbidity associated with meconium-stained deliveries.
