Clinical, bronchoscopic, spirographic, scintigraphic, and chemical analyses were done in 24 children with cystic fibrosis to assess the mucolytic effects of acetylcysteine inhalations versus L-arginine hydrochloride aerosols. The latter drug is less active than acetylcysteine and should not be used to treat children with cystic fibrosis.

Review of 158 patients with hyaline membrane disease was undertaken. The introduction of artificial ventilation with a positive end-expiratory pressure (IPPB and PEEP) has doubled the prevalence of pneumothorax, pneumomediastinum and interstitial emphysema from 20.7% to 39.7%). ⋯ No patient treated with CNP alone developed bronchopulmonary dysplasia. Patients treated with IPPB with PEEP had a marked decreased prevalence of bronchopulmonary dysplasia (17.2%) when compared to patients treated with IPPB alone (36.2%), probably related to the enhanced overdistension of relatively normal areas of the lung may be related to the increased prevalence of lung rupture seen during IPPB with PEEP.
