Admitting Orders for Acute Exacerbation of COPD
The standard admitting orders for a patient with acute exacerbation of COPD should include oxygen therapy with target saturation of 88-92%, short-acting bronchodilators, systemic corticosteroids, antibiotics if indicated, and appropriate monitoring of respiratory status. 1, 2
Initial Assessment and Monitoring
- Obtain arterial blood gases on arrival and repeat 30-60 minutes after initiating oxygen therapy 2
- Monitor oxygen saturation continuously with pulse oximetry 1, 2
- Check blood gases if clinical deterioration occurs, even if initial PCO2 was normal 2
- Consider spirometry at least once during admission if this is the patient's first presentation with presumed COPD 2
Oxygen Therapy
- Prescribe controlled oxygen therapy with target saturation of 88-92% 1, 2
- Use 24% Venturi mask at 2-3 L/min, nasal cannulae at 1-2 L/min, or 28% Venturi mask at 4 L/min 2
- For nebulizer treatments, use compressed air to drive nebulizers if the patient has hypercapnia and/or respiratory acidosis 1
- Continue oxygen via nasal prongs at 1-2 L/min during nebulization to prevent desaturation 1
Bronchodilator Therapy
- Order short-acting beta-2 agonist (salbutamol 2.5-5 mg or terbutaline 5-10 mg) via nebulizer 1
- Add anticholinergic (ipratropium bromide 0.25-0.5 mg) via nebulizer 1
- Administer nebulized bronchodilators every 4-6 hours initially, may be used more frequently if required 1
- After 24-48 hours or when patient is improving, transition to metered dose inhaler or dry powder inhaler 1
Corticosteroid Therapy
- Prescribe oral prednisolone 30 mg daily for 5-7 days 1, 3
- For patients unable to take oral medications, order intravenous hydrocortisone 100 mg every 6 hours 3
- Plan to discontinue corticosteroids after the acute episode (usually 7-14 days) unless there is a definite indication for long-term treatment 1, 3
- Transition from intravenous to oral corticosteroids as soon as the patient can tolerate oral medications 3
Antibiotic Therapy
- Prescribe antibiotics for patients with increased dyspnea, increased sputum volume, and increased sputum purulence 2, 4
- For mild to moderate exacerbations, order one of the following:
- For severe exacerbations or treatment failures, consider:
- Duration of antibiotic therapy should be 5-7 days 2
Additional Medications
- Consider intravenous methylxanthines (aminophylline 0.5 mg/kg/hour) by continuous infusion if patient is not responding to standard therapy 1
- If methylxanthines are used, monitor blood levels daily 1
- Order diuretics if peripheral edema and raised jugular venous pressure are present 1
- Consider prophylactic subcutaneous heparin for patients with acute respiratory failure 1
Ventilatory Support
- Initiate non-invasive ventilation (NIV) if respiratory acidosis persists (pH < 7.26) despite standard medical management 1
- Consider high-flow nasal cannula oxygen therapy as an alternative in selected patients 2, 5
Discharge Planning
- Begin early rehabilitation during hospitalization 2, 5
- Plan for influenza and pneumococcal vaccination if not up to date 4
- Schedule follow-up pulmonary function testing 4
Common Pitfalls to Avoid
- Avoid uncontrolled high-flow oxygen which may worsen hypercapnia 6
- Do not continue corticosteroids beyond 7-14 days unless specifically indicated 3
- Avoid prolonged courses of antibiotics beyond 7 days 3, 2
- Do not routinely use chest physiotherapy during acute exacerbations 1
- Avoid using intravenous corticosteroids when oral administration is possible, as IV route has higher risk of adverse effects 3
