Treatment for COPD Exacerbation
For acute COPD exacerbations, immediately initiate short-acting β2-agonists (albuterol) combined with short-acting anticholinergics (ipratropium), oral prednisone 40 mg daily for exactly 5 days, and antibiotics when sputum is purulent plus either increased dyspnea or sputum volume. 1
Bronchodilator Therapy
Acute bronchodilation is the foundation of exacerbation management:
- Administer short-acting β2-agonists (albuterol) with or without short-acting anticholinergics (ipratropium) as first-line therapy 1, 2
- For severe exacerbations, always combine both SABA and short-acting anticholinergics together—this provides superior bronchodilation compared to either agent alone 1
- Use either metered-dose inhalers with spacers or nebulizers; both are equally effective 1
- Nebulizers are strongly preferred for sicker hospitalized patients who cannot coordinate the 20+ inhalations needed to match nebulizer efficacy 1, 2
- Avoid intravenous methylxanthines (theophylline) entirely—they increase side effects without added benefit 1, 3
Systemic Corticosteroid Protocol
The corticosteroid regimen is standardized and time-limited:
- Give oral prednisone 40 mg daily for exactly 5 days—never extend beyond 5-7 days total 1, 2
- Oral administration is equally effective to intravenous and should be the default route unless the patient cannot tolerate oral intake 1, 2
- Corticosteroids improve lung function, oxygenation, shorten recovery time, and reduce hospitalization duration 1, 2
- Critical pitfall: Do not extend therapy beyond 5-7 days—there is no additional benefit and increased risk of side effects 1
- Corticosteroids may be less effective in patients with lower blood eosinophil levels, though this should not prevent their use 1, 2
Antibiotic Therapy
Antibiotics have mortality benefit when used appropriately:
- Prescribe antibiotics when there is increased sputum purulence PLUS either increased dyspnea OR increased sputum volume 1, 2
- Antibiotics reduce short-term mortality by 77%, treatment failure by 53%, and sputum purulence by 44% 1, 2
- Treat for 5-7 days with empirical therapy based on local resistance patterns 1, 2
- First-line choices include amoxicillin-clavulanate, macrolides (azithromycin), or tetracyclines 1
Oxygen Therapy for Hospitalized Patients
Controlled oxygen delivery prevents CO2 retention:
- Target oxygen saturation of 90-93% using controlled delivery (Venturi mask at ≤28% FiO2 or nasal cannula at 2 L/min initially) 1, 2
- Obtain arterial blood gas within 1 hour of initiating oxygen to assess for worsening hypercapnia and CO2 retention 1, 2
- Do not withhold oxygen for fear of CO2 retention—monitor with arterial blood gases and adjust accordingly 1
Respiratory Support for Severe Exacerbations
Noninvasive ventilation is first-line for acute hypercapnic respiratory failure:
- Initiate noninvasive ventilation (NIV) immediately as first-line therapy for patients with acute hypercapnic respiratory failure who have no absolute contraindications 1, 2
- NIV improves gas exchange, reduces work of breathing, decreases intubation rates, shortens hospitalization, and improves survival 1, 2
Treatment Setting Based on Severity
More than 80% of exacerbations can be managed outpatient:
- Mild exacerbations: Treat with short-acting bronchodilators only in the outpatient setting 1, 2
- Moderate exacerbations: Manage outpatient with bronchodilators plus antibiotics and/or oral corticosteroids 1, 2
- Severe exacerbations: Require hospitalization or emergency department visit, particularly with acute respiratory failure 1, 2
Discharge Planning and Prevention
Post-exacerbation care is critical for preventing readmissions:
- Initiate maintenance therapy with long-acting bronchodilators (LAMA, LABA, or combination) as soon as possible before hospital discharge 1, 2
- Schedule pulmonary rehabilitation within 3 weeks after discharge to reduce hospital readmissions and improve quality of life 1, 2
- At 8 weeks post-exacerbation, 20% of patients have not recovered to baseline, necessitating close follow-up 1, 2
- For patients with ≥2 exacerbations per year despite optimal bronchodilator therapy, consider adding inhaled corticosteroids (if asthma-COPD overlap or high eosinophils), roflumilast (if chronic bronchitis), or macrolide antibiotics (if frequent bacterial exacerbations) 1
Critical Pitfalls to Avoid
Common errors that compromise outcomes:
- Do not use roflumilast for acute exacerbations—it is only for prevention in severe COPD with chronic bronchitis and history of exacerbations 1, 4
- Always differentiate COPD exacerbations from mimics: acute coronary syndrome, heart failure, pulmonary embolism, and pneumonia 1
- Do not extend corticosteroid therapy beyond 5-7 days 1
- Avoid intravenous methylxanthines (theophylline) 1
