Acute exacerbations of COPD are acute worsenings of symptoms in a patient with COPD. It may be caused by viral respiratory infections, bacterial infections, pollution, or stress.
Exacerbations may vary in intensity from mild to very severe and life-threatening. Rapid assessment of the severity is important.
Clinical features
The cardinal symptoms of acute exacerbations are worsening dyspnoea, worsening cough, increased volume and/or purulence of sputum. In severe cases, respiratory failure may occur. If respiratory failure occurs, or if symptoms are severe, or if the patient has serous comorbidities, or if out-patient treatment has failed to improve symptoms, hospitalization is needed.
Diagnosis and evaluation
The diagnosis is based on clinical symptoms. If there are severe symptoms, ABG is used to assess the level of severity.
Treatment
In most cases, an increased dose of inhaled bronchodilators is necessary along with a short course of an oral corticosteroids like prednisolone. In Norway, ipratropium and salbutamol are usually administered in a nebulizer 4 times daily for the duration of the exacerbation.
If a bacterial infection is suspected, due to infectious signs or purulent or increased volume of sputum, empiric antibiotics can be given.
In cases more severe cases with respiratory failure, O2 supplement or non-invasive ventilation is used. In very severe cases, ICU admission and invasive ventilation is necessary. Admission to the ICU is indicated if:
- If conservative therapy doesn’t work
- PaO2 < 40 mmHg
- pH < 7,25
- Haemodynamic instability
