Study Notes

COPD Management

Smoking cessation is the only strategy impacting COPD progression favorably.
Pulmonary rehabilitation is encouraged for all stages and should reassure patients regarding breathlessness.
Bronchodilators are crucial to manage breathlessness.
- Short-acting bronchodilators are used as relievers and may be the sole treatment in very mild cases.
- Long-acting bronchodilators (LABA and LAMA) are available in single or combination inhalers.
- Nebulized short-acting bronchodilators are used for those unable to use inhalers.
Combined inhaled glucocorticoids and bronchodilators (LABA/LAMA/ICS or LABA/ICS) may benefit those with frequent exacerbations or persistent breathlessness despite long-acting bronchodilators.
- These therapies improve lung function, reduce exacerbations, and enhance quality of life.
- However, they increase the risk of pneumonia, particularly in older adults.
Oral anti-inflammatories:
- Oral glucocorticoids are helpful during exacerbations but long term use contributes to osteoporosis and muscle weakness.
- Roflumilast (phosphodiesterase-4 inhibitor) improves lung function and reduces moderate to severe exacerbations in severe COPD.
- Azithromycin (500 mg thrice weekly) can decrease exacerbation frequency.
Other maintenance measures:
- Pneumococcal and annual influenza vaccinations are recommended.
- Addressing obesity, poor nutrition, depression, and social isolation is crucial.

Oxygen Therapy and Ventilation

Long-term domiciliary oxygen therapy (LTOT) improves survival in patients with severe hypoxemia (PaO2 < 7.3 kPa or 55 mmHg).
- It should be used at least 15 hours per day, with greater benefits seen with usage exceeding 20 hours.
- The goal is to achieve PaO2 ≥ 8 kPa (60 mmHg) or SaO2 ≥ 90%.
Ambulatory oxygen therapy is considered for patients who desaturate during exercise and exhibit improvements in exercise capacity or dyspnea with oxygen.
- Oxygen flow rates need adjustment to maintain SaO2 > 90%.
Home non-invasive ventilation improves quality of life and prolongs time to readmission for patients with persistent hypercapnia.

Surgical Intervention

Bullectomy is an option for large bullae compressing surrounding lung tissue.
Lung volume reduction surgery (LVRS) may benefit patients with:
- Predominantly upper lobe emphysema
- Preserved gas transfer
- No evidence of pulmonary hypertension
- It involves resecting peripheral emphysematous lung tissue to reduce hyperinflation and ease breathing.
Bronchoscopic LVRS utilizes one-way valves, lung coils, or thermal ablation to collapse ineffective emphysematous lung tissue.
- This allows healthier lung tissue to expand and function better.
Lung transplantation may benefit carefully selected patients with advanced disease.

Palliative Care

Addressing end-of-life needs is paramount in advanced COPD.
- Morphine preparations can palliate breathlessness, and low-dose benzodiazepines can reduce anxiety.

Prognosis

COPD has a variable but usually progressive course.
Prognosis is inversely related to age and directly related to post-bronchodilator FEV1.
Poor prognostic indicators include weight loss and pulmonary hypertension.
The BODE index (body mass index, airflow obstruction, dyspnea, and exercise capacity) helps predict mortality from respiratory and other causes.
Common causes of death include respiratory failure, pneumonia, cardiac disease, and lung cancer.

Acute Exacerbations of COPD (AECOPD)

AECOPD is characterized by worsening symptoms, lung function decline, and health status deterioration.
They occur more frequently as the disease progresses and are often triggered by infection or air quality changes.
AECOPD can lead to respiratory failure and/or fluid retention, contributing to mortality.
Many patients can be managed at home with increased bronchodilators, short-term oral glucocorticoids, and, if necessary, antibiotics.
Cyanosis, peripheral edema, or altered consciousness necessitates hospital referral.

Oxygen Therapy in AECOPD

High oxygen concentrations may cause respiratory depression and worsen acidosis in severe COPD exacerbations.
Controlled oxygen (24% or 28%) is used to maintain SaO2 of 88%–92% or PaO2 > 8 kPa (60 mmHg) without worsening acidosis.

Bronchodilators in AECOPD

Nebulized short-acting β2-agonists combined with an anticholinergic agent (e.g., salbutamol and ipratropium) are routinely administered.

Glucocorticoids in AECOPD

Oral prednisolone reduces symptoms and improves lung function.
- The recommended dose is 30 mg for 5 days.

Antibiotic Therapy in AECOPD

The role of bacteria in exacerbations is controversial.
Routine antibiotic use is not well-supported, but they are recommended for patients with increased sputum purulence, sputum volume, or breathlessness.

Non-Invasive Ventilation (NIV) in AECOPD

NIV reduces mortality and invasive ventilation rates for patients with AECOPD complicated by mild to moderate respiratory acidosis (pH < 7.35).
- It is considered when respiratory acidosis isn't corrected within an hour despite optimal medical therapy, including controlled oxygen.
Invasive ventilation is considered for patients with deteriorating acidosis despite optimal NIV settings, those unable to tolerate the interface, and those who cannot protect their airway.

Additional Therapy in AECOPD

Exacerbations may lead to peripheral edema, which typically responds to diuretics.
