Corticosteroids in airway management

Abstract

Adrenal corticosteroids exert a strong suppressive influence on the basic inflammatory response that leads to tissue swelling. The corticosteroid effect is nonspecific. In upper airway obstruction caused by edema from infection, allergy, or trauma, corticosteroids will exert some degree of suppressive effect. The steroid effect is local and directly proportional to the concentration of steroids in the inflamed tissue. In upper airway obstruction steroids should be delivered to the inflamed tissue in high concentration with the least delay. Dexamethasone and methylprednisolone produce high blood levels within 15 to 30 minutes of intramuscular injection. Recommended initial doses for acute airway obstruction are dexamethasone, 1.0 to 1.5 mg/kg, or methylprednisolone, 5 to 7 mg/kg. The risk of harm from steroid therapy of 24 hours or less is negligible.
