Quizplus · Accepted Answer

Racemic epinephrine is often used via either inhaled aerosol or direct lung instillation for its strong ?-adrenergic vasoconstricting effect,to reduce airway swelling after extubation or during epiglottitis,croup,or bronchiolitis or to control airway bleeding during endoscopy.This effect would provide short-term bronchodilation,but little or no relief from airway edema.The ?-adrenergic vasoconstrictive response would slow the progress of airway edema.
