To the Editor:
—The articles on bronchial asthma by Drs. Unger and Abramson that appeared in the Oct. 11, 1952, issue of The Journal were excellent. Emphasis must be placed repeatedly on the danger of using morphine in asthma, as it so often is a cause of death in status asthmaticus. This applies to other strong respiratory depressants, like meperidine hydrochloride.I should like to add a suggestion for the prevention of what I call "nasal-descending asthma," a condition frequently following "head colds," which may provoke, especially in children, acute exacerbations of the severest type. I classify this into two forms, one in which severe asthma follows the nasal symptoms after minutes to hours and the other in which the severe chest symptoms occur after one or two days. The use of epinephrine in oil as Dr. Unger suggests is good for the first type, the more rapidly developing form.
