More on Meconium Aspiration

To the Editor.— The report by Wiswell et al in the May 1990 issue of Pediatrics1 provides valuable insight into meconium aspiration syndrome. However, I am concerned that there is a possible cause of meconium aspiration syndrome in the vigorous neonate which has not received enough emphasis, either in this or other reports. Namely, vigorours babies who develop meconium aspiration syndrome may be insidiously aspirating regurgitated meconium in the first few hours after leaving the delivery room.
