Treatment for COPD Exacerbation
The treatment of COPD exacerbation requires a combination of short-acting bronchodilators, systemic corticosteroids, and antibiotics when indicated, with noninvasive ventilation for severe cases with respiratory failure. 1
Pharmacological Management
Bronchodilators
- Short-acting inhaled β2-agonists (SABAs), with or without short-acting anticholinergics, are the initial bronchodilators recommended for acute treatment of exacerbations 1
- Either metered-dose inhalers (with or without spacer) or nebulizers can be used effectively, though nebulizers may be easier for sicker patients 1
- The combination of ipratropium and albuterol is more effective than either agent alone, providing superior peak effect and sustained bronchodilation 2
- Intravenous methylxanthines (theophylline) are not recommended due to increased side effect profiles 1
Corticosteroids
- Systemic glucocorticoids improve lung function (FEV1), oxygenation, and shorten recovery time and hospitalization duration 1
- A dose of 40 mg prednisone per day for 5 days is recommended (duration should not exceed 5-7 days) 1
- Oral prednisolone is equally effective to intravenous administration 1
- Corticosteroids may be less efficacious in patients with lower blood eosinophil levels 1
Antibiotics
- Antibiotics should be given when there is increased sputum purulence plus either increased dyspnea or increased sputum volume 1
- Antibiotics reduce the risk of short-term mortality by 77%, treatment failure by 53%, and sputum purulence by 44% 1
- Antibiotics are particularly important for patients requiring mechanical ventilation 1
- The recommended duration of antibiotic therapy is 5-7 days 1
- Antibiotic choice should be based on local bacterial resistance patterns; initial empirical treatment typically includes an aminopenicillin with clavulanic acid, a macrolide, or a tetracycline 1
Treatment Setting and Classification
Exacerbation Classification
- Mild: treated with short-acting bronchodilators only 1
- Moderate: treated with short-acting bronchodilators plus antibiotics and/or oral corticosteroids 1
- Severe: requires hospitalization or emergency room visit; may be associated with acute respiratory failure 1
Treatment Setting
- More than 80% of exacerbations can be managed on an outpatient basis 1
- Hospitalization should be considered for severe exacerbations, particularly with acute respiratory failure 1
Respiratory Support for Severe Exacerbations
- Targeted oxygen therapy should be titrated to an SpO2 of 88-92% 3
- Noninvasive ventilation (NIV) should be the first mode of ventilation for patients with acute respiratory failure who have no absolute contraindication 1, 3
- NIV improves gas exchange, reduces work of breathing, decreases need for intubation, shortens hospitalization duration, and improves survival 1
- For mechanically ventilated patients, management of auto-PEEP is a priority, achieved by reducing airway resistance and decreasing minute ventilation 3
Common Pitfalls and Caveats
- Roflumilast is indicated for reducing the risk of COPD exacerbations in patients with severe COPD associated with chronic bronchitis and a history of exacerbations, but is not indicated for the relief of acute bronchospasm during an exacerbation 4
- Oral corticosteroids should be limited to 5-7 days to minimize side effects while maintaining efficacy 1
- MDI with spacer delivery of bronchodilators is as effective as nebulized therapy in most cases, though nebulizers may be easier for severely ill patients 1, 5
- Patients with frequent exacerbations (≥2 per year) have worse health status and morbidity, requiring more aggressive preventive strategies after the acute episode 1
- At 8 weeks after an exacerbation, 20% of patients have not recovered to their pre-exacerbation state, highlighting the importance of follow-up care 1
Follow-up After Exacerbation
- Maintenance therapy with long-acting bronchodilators should be initiated as soon as possible before hospital discharge 1
- Follow-up visit after an acute exacerbation provides an opportunity to help the patient plan for future exacerbation prevention 1
- Appropriate measures for exacerbation prevention should be initiated, including smoking cessation counseling and medication review 1
