Chylothorax in two mongoloid infants.

Abstract

Two newborns with stigmata of Down syndrome required resuscitation at birth because of unilateral congenital chylous pleural effusion. After thoracentesis, ventilation was improved. Congenital chylous pleural effusion in newborns with Down syndrome has not previously been described. Pleural effusion at birth must be promptly diagnosed and aspirated.
