Dexamethasone Dosing for Airway Edema
Pediatric Population
- The French guidelines support repeated doses of IV dexamethasone before and after tracheal extubation in neonates at risk for laryngeal edema following traumatic or repeated intubation 1, 2
- A negative cuff leak test increases risk of laryngeal edema, postextubation stridor, and reintubation in children 1, 2
- Epinephrine nebulization may be used for postextubation stridor in children, with effectiveness lasting 2 hours, requiring PACU or ICU monitoring 1, 2
Adult Population
- Dexamethasone 4-8 mg/day is recommended for moderately symptomatic patients with symptomatic brain metastases with vasogenic edema 3
- Dexamethasone 16 mg/day is recommended for patients with marked symptoms, mass effect, elevated intracranial pressure, or impending herniation 3
Administration Considerations
- IV and oral bioavailability of dexamethasone are equivalent (1:1 conversion), with 40 mg IV being equal to 40 mg oral 4
- Antifungal prophylaxis should be strongly considered in patients receiving prolonged steroids 4, 5
