The extensive study recently reported by Sherman and co-workers attempts to evaluate the use of early tracheal aspiration in diagnosing congenital pneumonia.1 Their findings are of interest and confirm some previous studies and clinical impressions.
However, the authors' conclusion that "early direct tracheal aspiration ... appears to be a specific ... procedure for the early diagnosis of congenital pneumonia" does not seem to be supported by the data they present.
Specifically, for their conclusion to be valid, a definite correlation of positive tracheal aspirates with presence of pneumonia must be made.
