acute bronchitis

1. An infection of the bronchi that may be indistinguishable from the common cold, often associated with repetitive coughing or sputum production. It is usually caused by viruses (particularly rhinoviruses, influenza A or B, parainfluenza, adenoviruses, or respiratory syncytial virus) or less often by Mycoplasma pneumoniae, Chlamydia, streptococci, Haemophilus spp, Moraxella lacunata, Bordetella pertussis, or staphylococci.
2. Noninfectious inflammation of the bronchi caused by exposure to such irritants as dusts, fumes, or pollens.

Patient care

Patients are treated with bedrest, increased fluid intake, and antipyretics and analgesics for comfort. Antibiotics are rarely indicated (even if purulent sputum is present), unless bacterial infection is determined by culture or the symptoms continue for more than 10 days or there is an underlying disease such as congestive heart failure, chronic obstructive lung disease, or an immunodeficiency. Some prolonged cases of acute bronchitis will eventually prove to be caused by pertussis, which will respond to erythromycin-based drugs. A chest x-ray examination to check for pneumonia is indicated when clinically suspected (the presence of severe respiratory symptoms, fever, tachycardia, hypoxia, or abnormal lung sounds).
