The effect of isoproterenol on airway obstruction in cystic fibrosis.

The effect of isoproterenol inhalations was studied on 95 occasions in 47 patients with cystic fibrosis.Spirometric and airway resistance measurements showed small but statistically significant changes in the MMEF, MBC and airway resistance, although there was considerable variation from patient to patient. Over-inflation of the lungs, as indicated by a high thoracic gas volume, was not significantly decreased by the administration of the drug.It is suggested that before using isoproterenol routinely as a treatment for cystic fibrosis, response to this drug should be measured in each individual patient.

Negative pressure artificial respiration: use in treatment of respiratory distress syndrome of the newborn.

Forty-five newborn infants in respiratory failure with respiratory distress syndrome were treated with intermittent negative pressure ventilation (INPV). There was a survival rate of 38% (17/45).All infants were initially treated without nasotracheal intubation. However, 24 of these developed a Paco(2) greater than 70 mm. Hg and were subsequently intubated. Intubation was followed by a decrease in the degree of hypercarbia in each instance and simultaneous increase in Pao(2).COMPLICATIONS ENCOUNTERED DURING VENTILATION WERE: emphysema (one patient), aspiration pneumonia (two patients), septicemia (two patients), misplaced nasotracheal tube (one patient).Follow-up of the 17 surviving patients for periods of four to 36 months disclosed two patients with post-intubation hoarseness. One infant initially had spastic quadriplegia with EEG abnormalities, both of which cleared by 5 months of age. In the remaining 14 infants, the results of physical, neurological and psychological examinations have remained within normal limits.
