The Procedural Approach For Respiratory Diseases

Acute bronchitis often develops from a cold or respiratory infection, and it is common. Chronic bronchitis, a more severe condition, results from continuous irritation or inflammation of the bronchial tubes, typically caused by smoking.

Symptoms of Chronic Bronchitis:

• Mucus production (sputum): This can be clear, white, gray, or yellowish/green, and rarely may be tinged with blood.
• Fatigue
• Shortness of breath
• Mild fever and chills
• Chest tightness
• Wheezing
• Continuous cough
• Sputum production
• Discomfort and constant irritation

Causes of Bronchitis:

The airway is lined with a mucus membrane that is highly sensitive to irritants. This sensitivity causes a rapid response and increased mucus production, as well as thickening of the muscle layer inside the bronchial walls.

The irritants that can cause bronchitis include:

• Tobacco smoke
• Dust (especially asbestos, coal, cotton, and silica)
• Smog and chemical vapors like sulfur dioxide or nitrogen dioxide
• Gastroesophageal reflux (GERD)
• Viral strains (such as those causing influenza) and some bacteria also play a role in causing and prolonging bronchitis.

Diagnosis of Chronic Bronchitis:

The most prominent sign of chronic bronchitis is a persistent cough accompanied by sputum. This is the primary diagnostic criterion. Other tests may include:

• Physical examination: It can reveal wheezing and prolonged exhalation time, indicative of the disease.
• Chest X-ray: This helps exclude other lung conditions that may cause cough, such as pneumonia.
• Lung function tests: These tests evaluate the breathing process, lung efficiency, and help diagnose respiratory diseases, including asthma and respiratory infections.
• CT scan: To provide detailed images of the lungs.

Complications of Chronic Bronchitis:

• Shortness of breath
• Pneumonia
• Respiratory failure
• Pneumothorax (collapsed lung)
• Polycythemia (excessive red blood cells)

Treatment of Chronic Bronchitis:

While there is no definitive cure for chronic bronchitis, the disease can be managed and controlled with medication and lifestyle changes, especially when diagnosed and treated early.

• Stop smoking: The first step in treatment is smoking cessation.

Medications:

• Bronchodilators: These medications open the airways in the lungs, making it easier to breathe. These are often administered via an inhaler (such as Albuterol and Ipratropium).
• Steroids: To reduce inflammation, often used in inhaled form, but sometimes orally, if symptoms persist.
• Antibiotics: If the infection is bacterial, antibiotics such as Levofloxacin may be prescribed.
• Cough suppressants: Such as Guaifenesin to alleviate symptoms.

Pulmonary Rehabilitation: This is a program aimed at improving breathing through specific breathing exercises taught by a specialist.

Nursing Care for Acute Bronchitis:

• Improve secretion clearance through walking, deep breathing, and controlled coughing.
• Increase fluid intake to loosen mucus and prevent dehydration, which can be common due to rapid breathing and fever.
• Provide rest and avoid bronchial irritants, while maintaining a light and healthy diet to facilitate recovery.
• Educate patients to complete the full course of antibiotics if prescribed and avoid over-the-counter antihistamines, cough suppressants, or decongestants, which may exacerbate mucus retention.
• Encourage the patient to quit smoking completely.
• Educate the patient to recognize early symptoms of acute bronchitis and report them immediately.

Nursing Interventions for Chronic Bronchitis:

• Answer patient’s questions and encourage them and their family to express concerns about the disease.
• Perform chest physiotherapy, including chest percussion, vibration, and postural drainage multiple times a day.
• Ensure the patient gets enough fluids (around 3 liters per day) to ease mucus clearance.
• Schedule respiratory therapy before meals or an hour after meals.
• Provide oral care after bronchodilator inhalation.
• Promote daily activities and offer recreational activities when appropriate.
• Encourage the patient to alternate between periods of activity and rest to avoid fatigue.
• Monitor for changes in the quality and quantity of sputum, increased respiratory rate, changes in breath sounds, and sleep disturbances.
• Check the patient’s weight regularly (three times a week).
• Assess nutritional status regularly.
• Look for signs of respiratory infections, such as increased cough, fever, and purulent sputum, and report these changes immediately.
• Advise the patient to avoid crowds and people with known respiratory infections and encourage vaccinations for pneumonia and influenza.
• Provide medications as prescribed and monitor the patient’s response.
• Assist with adjustments to respiratory function as needed.
