Lung function of children with history of obstructive bronchitis in their infancy.

A group of 98 children admitted to the hospital in the first 2 years of life with diagnosis of obstructive bronchitis was reexamined at 10 years of age. The examination included complexed lung function measurements. No important functional abnormalities were found in relation to passed obstructive bronchitis, features of allergy, frequency of attacks of the disease in the past, and bronchial reactivity to histamine. In the small group of children with diagnosis of bronchial asthma in the meantime made, the results of examination were most frequently abnormal but did not coincide with the previous diagnosis. They indicated rather nonhomogeneity of ventilation, characteristic for peripheral lung abnormalities.
