[Bronchiolitis. Our clinical experience in the 4 years from 1981 to 1984].
The clinical experience of 661 children with bronchiolitis is reported in four-years period to gain a better understanding of diagnosis and pathogenesis of bronchiolitis. Upper airways infections, expiratory dyspnea, clear sound by chest percussion, vesicular rales and whistling by chest auscultation, air trapping on the chest radiography were considered as essential data of diagnosis. It was found in 595 patients: expiratory dyspnea, air trapping, vesicular r. and whistling in 85% and whistling only in 15%; hypoxemia in 20% combined with hypercapnic acidosis in 10%; normoxemia in 80% combined with hypocapnia in 54%; hyperlactemia in 64% combined with an increment in the serum of CPK in 50% and of GPT in 30%; virus were cultured in 27%, adenovirus and RSV were identified in 90%. Instead it was found in 66 patients: air trapping but no difficult breath, with normal chest auscultation; crisis of cyanosis or paleness-cyanosis chilly sweat in 80% were motive of admission. The clinical and/or radiological features of "air trapping" were considered as essential symptoms and signs of bronchiolitis. The insufficient systemic perfusion was considered as a frequent occurrence and as cause for sudden respiratory and circulatory emergency.
