Adrenaline administered via a nebulizer in adult patients with upper airway obstruction

Racemic adrenaline administered via a nebulizer has been used successfully in children with upper airway obstruction resulting from croup and postintubation oedema. We report four adult cases of upper airway obstruction of differing aetiologies successfully managed with the administration of adrenaline via a nebulizer (1 mg in 5 ml of normal saline and repeated as necessary). This appears to be safe and effective in selected cases of upper airway obstruction with immediate benefits and few cardiovascular sequelae.
