1. Introduction

Bronchiectasis is a chronic respiratory disorder characterized by permanent abnormal dilatation of the bronchi and bronchioles due to destruction and weakening of the bronchial wall.

NORCET Definition:
Bronchiectasis = permanent bronchial dilatation associated with chronic airway inflammation, impaired mucus clearance and recurrent respiratory infections.

The damaged airways become inefficient at clearing secretions. Thick mucus accumulates, promotes bacterial colonization and produces a cycle of infection → inflammation → airway damage → further secretion retention.

Commonly Involved Areas

• Lower lobes may be commonly affected.
• Localized disease can occur after previous infection or obstruction.
• Diffuse disease may occur in systemic or genetic disorders.

2. Causes and Risk Factors

Major Causes

• Previous severe respiratory infections
• Tuberculosis
• Severe bacterial pneumonia
• Pertussis
• Measles-related respiratory complications
• Primary ciliary dyskinesia
• Cystic fibrosis
• Immunodeficiency disorders
• Allergic bronchopulmonary aspergillosis (ABPA)
• Bronchial obstruction by foreign body or tumor
• Recurrent aspiration
• Autoimmune/connective tissue disorders

Risk Factors

• Recurrent lower respiratory tract infections
• Smoking and chronic exposure to airway irritants
• Impaired cough or mucus clearance
• Immunosuppression
• Airway obstruction

Exam Alert: Always think about cystic fibrosis, primary ciliary dyskinesia, immunodeficiency, ABPA and previous severe infections when asked about important underlying causes.

3. Pathophysiology

1. Initial airway injury or infection occurs.
2. Inflammation damages the bronchial wall.
3. Elastic and muscular components of the bronchial wall are destroyed.
4. Bronchi become permanently dilated.
5. Mucociliary clearance becomes impaired.
6. Secretions accumulate in the dilated airways.
7. Bacterial colonization occurs.
8. Repeated infections produce further inflammation and tissue destruction.

Classic vicious cycle:
Airway damage → impaired mucus clearance → secretion retention → bacterial infection → inflammation → further airway damage.

Types Based on Bronchial Appearance

Type	Characteristic
Cylindrical	Uniform tubular dilatation of bronchi.
Varicose	Irregular bronchial dilatation with alternating narrowing.
Cystic/Saccular	Marked dilatation forming sac-like or cystic spaces.

High-Yield: Cylindrical → Varicose → Cystic represents increasing severity of bronchial structural distortion.

4. Clinical Manifestations

Respiratory Symptoms

• Chronic productive cough
• Large amounts of purulent sputum
• Recurrent chest infections
• Dyspnea
• Wheezing
• Fatigue
• Chest discomfort or pleuritic pain

Hemoptysis

Hemoptysis may occur because chronically inflamed bronchial arteries become fragile. It can range from blood-streaked sputum to severe bleeding.

Emergency: Massive or rapidly increasing hemoptysis can compromise the airway and breathing. Airway, breathing and circulation take priority.

Other Findings

• Fever during acute infective exacerbations
• Clubbing in chronic severe disease
• Coarse crackles, especially over affected areas
• Rhonchi/wheezing in some patients
• Weight loss in advanced chronic disease
• Reduced exercise tolerance

5. Diagnostic Evaluation

1. High-Resolution CT Chest

HRCT chest is the key imaging investigation for confirming bronchiectasis and defining its extent and distribution.

2. Chest X-Ray

May show bronchial wall thickening, linear opacities or other chronic changes, but may be less sensitive than CT.

3. Sputum Examination

• Gram stain and culture may identify infecting organisms.
• Culture helps guide antibiotic therapy.

4. Pulmonary Function Tests

May demonstrate obstructive, restrictive or mixed abnormalities depending on the extent and underlying cause.

5. Additional Tests

• Complete blood count during infection
• Immunoglobulin testing when immunodeficiency is suspected
• Evaluation for cystic fibrosis when clinically appropriate
• Testing for ABPA when suspected
• Bronchoscopy when obstruction, foreign body or localized disease requires evaluation

NORCET Must Remember:
Best imaging test for bronchiectasis → High-resolution CT (HRCT) chest.

6. Complications

• Recurrent respiratory infections
• Massive hemoptysis
• Respiratory failure
• Chronic hypoxemia
• Pulmonary hypertension
• Cor pulmonale in advanced disease
• Lung abscess
• Secondary amyloidosis — uncommon but possible in longstanding disease

7. Medical Management

Main Goals

• Improve mucus clearance
• Treat acute exacerbations
• Reduce frequency of infections
• Improve lung function and exercise tolerance
• Control symptoms
• Manage the underlying cause
• Prevent complications

1. Airway Clearance

Airway clearance techniques are a major component of bronchiectasis management.

• Active cycle of breathing techniques (ACBT)
• Directed coughing / huff coughing
• Chest physiotherapy when appropriate
• Postural drainage in selected patients
• Positive expiratory pressure devices when prescribed
• Adequate hydration when not contraindicated

2. Antibiotics

Antibiotics are used for infective exacerbations and, in selected patients, for prevention of recurrent exacerbations under specialist guidance.

Sputum culture can help select appropriate antimicrobial therapy, particularly in patients with recurrent infection or resistant organisms.

3. Bronchodilators

May be prescribed when airflow obstruction, wheezing or coexisting airway disease is present.

4. Inhaled Therapy

Selected patients may receive inhaled medications based on symptoms, airflow limitation and underlying disease.

5. Oxygen Therapy

Supplemental oxygen may be required in patients with significant chronic or acute hypoxemia according to clinical assessment.

6. Surgery

Surgical resection may be considered in carefully selected patients with localized severe disease, recurrent complications or uncontrolled bleeding despite appropriate medical treatment.

7. Treatment of Underlying Cause

• Management of immunodeficiency
• Treatment of ABPA when present
• Management of cystic fibrosis-related disease
• Removal of airway obstruction when indicated
• Management of aspiration risk

8. Nursing Management

A. Assessment

• Assess respiratory rate, rhythm and work of breathing.
• Monitor oxygen saturation.
• Assess breath sounds.
• Observe sputum amount, color, consistency and odor.
• Assess cough effectiveness.
• Monitor temperature.
• Assess hemoptysis.
• Monitor activity tolerance.
• Assess nutritional and hydration status.

B. Maintain Airway Clearance

• Encourage effective coughing and huff coughing.
• Assist with prescribed airway-clearance techniques.
• Encourage adequate fluid intake if not contraindicated.
• Provide humidification when prescribed.
• Position the patient appropriately for secretion drainage.
• Encourage mobilization as tolerated.

C. During Hemoptysis

• Assess amount and severity of bleeding.
• Monitor airway and oxygenation.
• Keep suction and emergency equipment available.
• Maintain IV access if clinically indicated.
• Notify the medical team promptly for significant bleeding.
• Prepare for further diagnostic/interventional management when required.

Important: Do not treat significant hemoptysis as an ordinary cough. Airway protection and oxygenation are priorities.

D. Infection Prevention

• Monitor for fever and worsening sputum.
• Collect sputum specimens correctly when ordered.
• Administer prescribed antibiotics on schedule.
• Teach respiratory hygiene and hand hygiene.
• Encourage recommended vaccinations.

E. Nutrition

• Provide small, frequent, nutrient-dense meals if fatigue is present.
• Monitor body weight.
• Address increased nutritional needs during recurrent infections.

F. Patient Education

• Explain the chronic nature of the disease.
• Teach airway-clearance techniques.
• Teach correct inhaler/nebulizer technique when prescribed.
• Encourage adherence to medications.
• Advise patients to report increased sputum, change in sputum color, fever, worsening breathlessness or hemoptysis.
• Advise avoidance of smoking and respiratory irritants.
• Promote appropriate vaccination and follow-up.

9. Bronchiectasis vs COPD

Feature	Bronchiectasis	COPD
Basic problem	Permanent bronchial dilatation with chronic airway inflammation	Persistent airflow limitation due mainly to airway/parenchymal disease
Sputum	Often large-volume and purulent	May be chronic, especially in chronic bronchitis phenotype
Recurrent infection	Common	Exacerbations can occur
Key imaging	HRCT demonstrates bronchial dilatation	CT may show emphysema/hyperinflation depending on phenotype
Hemoptysis	Can occur and may be significant	May occur but is not a defining feature
