Revision as of 03:34, 23 February 2014
Background
- Inflammation of large airways of the lung
- PNA must be excluded by clinical evaluation or by CXR
- If all 5 are negative PNA is safely excluded:
- 1. HR >100
- 2. RR >24
- 3. Temp >38 (100.4)
- 4. Exam findings c/w focal consolidation, egophony, or fremitus
- 5. Age >64yr
- If all 5 are negative PNA is safely excluded:
Epidemiology
- Viruses are most common cause
- Influenza, paraflu, RSV, corona, adeno, rhino
- Bacterial cause occurs in <10% of cases
- Mycoplasma, C. pneumoniae, pertussis (1% of bronchitis cases)
Diagnosis
- Cough, with or without sputum, without e/o PNA, common cold, or Asthma
- Cough >5d is more suggestive of bronchitis than common cold
- Cough may persist for 10-20d
- Cough >3wk suggests asthma, COPD, pertussis, postnasal drip, GERD
- Often follows URI
Work-Up
- CXR only indicated in elderly or suspicion for PNA
Treatment
- American College of Chest Physicians 2006 Guidelines[1]
- Routine treatment w/ abx is not justified
- Antitussive agents can be useful (codeine, dextromethorphan)
- In individuals without comorbidities antibiotics have no improvement in symptoms or duration [2]
- Do not treat patients with antibiotics unless:[3]
- older than 65 years
- recent hospitalizations in the past year
- Diabetes
- On chronic steroids
- If treating based upon the above criteria then a 5 day treatment is preferred [4]
- Bronchodilators only useful if there is wheezing
