Acute bronchitis is defined by a cough which persists for MORE THAN 5 DAYS
- Fever is unusual in acute bronchitis if your patient has a fever consider pneumonia
- (95%) of acute bronchitis is viral
- Bacterial causes of acute bronchitis include:
- M. Catarrhalis (the common bacterial cause of acute bronchitis)
- H. influenzae
- S. Pneumoniae
Chest X-Ray if diagnosis is uncertain or symptoms have persisted despite conservative treatment
Since most cases (95%) are viral symptomatic treatment is the cornerstone of management:
- Supportive measures include hydration, expectorants, analgesics, β2-agonists, and cough suppressants as needed (not recommended for children).
- For acute exacerbations of chronic bronchitis, in which bacterial causes are more likely, empiric first-line treatment is a second-generation cephalosporin; second-line treatment is a second-generation macrolide or trimethoprim-sulfamethoxazole.
- Antibiotics are indicated for the following: elderly patients, those with underlying cardiopulmonary diseases and a cough for more than 7 to 10 days, and any patient who is immunocompromised.
Amoxicillin/clavulanic acid 875 mg two times per day for 10 days
antibiotics which are usually not indicated in the treatment of acute bronchitis
Doxycycline 100 mg PO two times per day for 14 days
antibiotics are usually not indicated in the treatment of acute bronchitis
Increased fluids and ibuprofen
Give the patient an albuterol inhaler
Albuterol, is a beta-agonist used as a bronchodilator (usually in asthma); here, it should be used only if there is evidence of bronchoconstriction.
Treat with a macrolide antibiotic
Administer penicillin intramuscularly
Penicillin would not be an appropriate treatment for acute bacterial bronchitis
Influenza titers are not necessary if you suspect a bacterial etiology.
Pulmonary function tests
Pulmonary function tests in acute bronchitis are not necessary, except in very serious cases.
The same bugs that cause upper respiratory infections cause acute bacterial bronchitis: H. influenzae, M. Catarrhalis and S. Pneumonia
Fungi are usually not considered when acute bronchitis is the diagnosis, you may be more suspicious in a patient who is immunocompromised.
Acute bronchitis is not an allergic reaction.
Oseltamivir 75 mg on day two of symptoms
Although oseltamivir (Tamiflu) given within 2 days of symptom onset for Influenza A/B may decrease symptom duration it is not considered prophylaxis.
corticosteroids are never used as prophylaxis for an infection.
this antifungal medication is never used in acute bronchitis.
