Brassy Cough

Brassy or Metallic sound  of cough is a characteristic feature of Bacterial tracheaitis , it's not associated with drooling or dysphagia and usually it's predisposed by a viral infection in a less than 3 years old child (remember the concept of normally small /narrow airways in younger children ), and it's caused by Staph aureus.

management is through supporting airways through inhaled corticosteroids besides an appropriate Antistaph. antibitotic.
