[Pharmacoloby of the bronchomotor tonus during anesthesia].
In a patient under general anesthesia, the occurrence of bronchospasm can be readily treated provided the cause is diagnosed early. The corrective drugs to dilate are readily available: atropine, epinephrine and theophylline. In the choice of preanesthetics, anesthetics and adjuvants, it is important to remember that there are differences in the bronchomotor effects; most curareform drugs constrict except pancuronium; most inhalational anesthetics dilate in contrast to intravenous anesthetics. In the event that bronchospasm cannot be re relieved by drugs, intubation and assisted breating can be applied to maintain adequate gas exchange in the alveoli.
