CLASSIFICATION OF ACUTE RESPIRATORY DISORDERS

Experience suggests that many newborn infants with acute respiratory disorders do not fit classic diagnostic patterns. There also is considerable variation among authors about which particular diagnostic criteria should be relied upon to define common disorders, such as respiratory distress syndrome (RDS), also known as hyaline membrane disease (HMD). In 1962, Miller classified patients having RDS based on oxygen therapy, grunting, and respiratory rate but used no radiographic criteria for diagnosis, despite the fact that Donald and Steiner had described the reticulogranular or ground glass pattern now regarded as the “classic” radiographic picture of RDS in 1953. In a review of 39 pediatric and neonatology textbook and articles in 1991, Teji and David found the presence of a reticulogranular pattern on chest film the most widely agreed upon criterion for establishing the diagnosis of RDS, with 70% of authors in agreement.Clearly, diagnostic criteria evolve over time with our understanding of the features, pathophysiology and treatment of diseases.
