慢性閉塞性肺疾患 V: 管理

Smoking cessation is the most critical intervention for COPD patients who smoke because it slows disease progression, reduces exacerbation frequency, and improves lung function. Healthcare providers educate patients about smoking risks and help establish a specific quit date. Methods include behavioral therapy, nicotine replacement therapy, and medications like bupropion or varenicline to support successful cessation.

COPD treatment uses both short-acting and long-acting bronchodilators. Short-acting beta-agonists and anticholinergics relieve acute symptoms, while long-acting beta-agonists and anticholinergics provide long-term symptom control. These medications are administered via pressurized metered-dose inhalers, small-volume nebulizers, or dry-powder inhalers depending on patient preference and clinical need.

Oxygen therapy begins when oxygen saturation drops below 88% at rest or during exercise. Long-term oxygen therapy improves survival, enhances quality of life, and increases exercise capacity in patients with severe resting hypoxemia. Oxygen can be delivered via nasal cannulas, masks, or transtracheal systems based on individual patient needs and activity levels.

Inhaled corticosteroids are often combined with long-acting bronchodilators, particularly for patients with frequent exacerbations. Oral corticosteroids treat acute exacerbations but should be avoided for long-term use due to significant side effects including osteoporosis, hyperglycemia, and muscle weakness. Anti-inflammatory agents work alongside corticosteroids to reduce airway inflammation.

Pulmonary rehabilitation programs provide exercise training, nutritional counseling, and education to improve physical and emotional participation and overall quality of life. These programs also include airway clearance techniques such as chest physiotherapy and postural drainage to help clear mucus. Emotional support addresses anxiety and depression, which are common comorbidities in chronic obstructive pulmonary disease patients.

Surgical interventions for severe COPD include bullectomy, which removes large bullae to improve lung function in selected patients, and lung volume reduction surgery, which removes damaged lung tissue to enhance function and quality of life in emphysema cases. Lung transplantation is considered in advanced COPD when other treatments have failed, requiring careful patient selection and multidisciplinary evaluation.

Supportive therapies include annual influenza and pneumococcal vaccinations to prevent infections, nutritional support to address undernutrition, and regular physical activity to improve strength and endurance. Management of comorbidities such as cardiovascular disease, osteoporosis, anxiety, and depression is essential. A multidisciplinary team including pulmonologists, nurses, physical therapists, and dietitians provides comprehensive individualized care.
