Abstract
Patients [16] in whom bronchospasm developed during general endotracheal anesthesia were studied. The severity of wheezing and peak airway pressure decreased in every patient after the initial administration of isoetharine. The data obtained support the conclusion that metered-dose nebulization of isoetharine is a useful technique for the treatment of bronchospasm occurring during anesthesia, and that since its use results in few cardiovascular actions, it may be preferable to isoproterenol. The latter particularly may be the case in management of patients who have pre-existing myocardial irritability.
