Bronchiectasis is a chronic lung condition characterized by abnormal, permanent dilation of the bronchi and bronchioles. It is most commonly caused by recurrent lung infections that destroy the airways over time. The main symptoms include a persistent cough with sputum production, respiratory infections, hemoptysis, dyspnea, and nail clubbing in severe cases. Diagnosis is made through chest imaging such as high-resolution CT scan that shows the dilated airways. Treatment involves controlling infections with antibiotics, clearing secretions through chest physiotherapy, treating any underlying causes, and surgery in rare cases of localized disease. Complications can include recurrent pneumonia, lung abscesses, and respiratory failure in advanced cases.

2. Abnormal permanent dilatation of bronchior sub
segmental bronchi with inflammatory destruction of
peribronchial tissue [muscle, cartilage] with accumulation of
secretions in the dependent bronchi
Bronchiectasis is a chronic, irreversible dilation of the
bronchi and bronchioles. Under the new definition of COPD,
it is considered a separate disease process from COPD
(NIH, 2001).
BRONCHIECTASIS – DEFINITION
It is common in
age group of 5‐15
Years
Types
Congenital
/ Hereditary
Acquired

3. CAUSES / ETIOLOGY
•Airway obstruction
•Diffuse airway injury
•Recurrent Pulmonary infections
•Obstruction of the bronchus or complications of long-term
pulmonary infections
•Genetic disorders such as cystic fibrosis, Ciliary abnormalities
‐ Kartageners syndrome, Immotile cilia syndrome, yellow nail
syndrome, alpha 1 anti‐trypsin deficiency
•Abnormal host defense (eg, ciliary dyskinesia or humoral
immunodeficiency)
•Aspiration
•Childhood infections – measles, pertussis

5. TYPES
Classic ‘Reid’ classification (gross histological
appearance) ‐ three different patterns
1. Cylindrical bronchiectasis ‐ mildly uniform
airway dilation
2.Varicose bronchiectasis ‐ focally dilated areas
between narrowed segments
3.Saccular bronchiectasis ‐ balloon‐like airway
dilation with more disruption of lung parenchyma

7. PATHOGENESIS
8
• Chronic infection – recruitment of neutrophils,
T‐lymphocytes, monocyte‐derived cytokines with
release of inflammatory mediators ‐ elastases &
collagenases
• Loss of ciliated columnar epithelium
• Micro‐abscess in bronchial wall with
peribronchial inflammation
• Destruction ‐ elastic & muscle tissue, cartilage of
bronchus.
• Endarteritis of pulmonary vessels
• Bronchial arterial proliferation (predisposes to
hemoptysis)

9. CLINICAL MANIFESTATIONS
10
• Most common symptom ‐ persistent cough, typically
"wet" or productive
• Episodic exacerbations of infection‐
• Increased cough and sputum production
• Fever
• Pleuritic chest pain
• Dyspnea
• Absence of sputum production does not exclude
bronchiectasis (younger children may not be able to
expectorate)
Contd..

10. • Hemoptysis ‐ uncommon in children
• Occurs ‐ erosion of inflamed airway tissue adjacent to
pulmonary vessels.
• Bleeding
• Mild, with blood streaked sputum
• Profuse amounts of fresh bleeding if larger
pulmonary vessels rupture.
• Dyspnea and exercise intolerance
• Uncommon at presentation
• May develop as disease progresses
• May occur during acute exacerbation (intercurrent
infection)
Contd
11
CLINICAL MANIFESTATIONS

11. • Cyanosis‐ severe bronchiectatic lung disease
• Severe hypoxemia due to mismatched pulmonary
ventilation and perfusion.
• Nail clubbing
• If hypoxemia ‐ prolonged and profound‐ cause
pulmonary hypertension & cor‐pulmonale.

CLINICAL MANIFESTATIONS

12. PHYSICAL EXAMINATION
13
1. General physical examination
2. Symptoms of cough – copious amount; pus +/- &
Haemoptysis
3. Sinus and ear infections
4. Presence of congenital anomalies
5. Signs - Clubbing
1. Schamroth sign‐ obliteration of the quadrangular
space when both fingers kept in unison
2. Distal phalangeal depth (DPD) to interphalangeal
depth ratio (IPD) > 1
6. Coarse leathery crackle over areas of bronchiectasis

14. DIAGNOSIS
• Diagnosis depends on radiographically or anatomically visualizing
abnormal dilatation of airways
• Diagnostic procedure of choice ‐ High‐Resolution Computed
Tomography (HRCT) scan
• Other tests‐ diagnose underlying conditions.
• Contd..

15. LABORATORY
INVESTIGATIONS
16
 Complete blood count with differential
 Sputum exam‐ volume, gram stain, C & S ,
 Immunodeficiency‐ Total IgM, IgA and IgG
 Tests for Tuberculosis –
• Mantoux
• Chest X‐ray
• Resting Gastric juice for AFB
 Test for cystic fibrosis (sweat chloride and/or DNA
testing)
 HIV screening

16. INVESTIGATIONS
 Flexible bronchoscopy
• shows structural alteration of bronchial tree
• bronchoalveolar lavage ‐ remove mucus plugs/ to obtain
lower airway cultures.
• If an airway foreign body is discovered‐rigid
bronchoscopy ‐for removal
 Ciliary biopsy
• Test for GERD : 24 hour pH monitoring, upper
gastrointestinal endoscopy and technetium milk scan
scintigraphy.
• Test for aspiration due to inadequate airway protective
mechanisms during swallowing or dysphagia
‐evaluated by video fluoroscopy
17

17. INVESTIGATIONS
• Pulmonary function tests ‐severity of lung disease
• should be performed if the patient is able to do
• useful tool to evaluate long‐term progression of lung
disease.
• Most patients with bronchiectasis have features of
obstructive lung disease (low FEV1 & FEV1/FVC ratio)
• Test for allergic bronchopulmonary aspergillosis
• Immunoglobulin E (IgE)
• Serum precipitins for Aspergillus species
• Sputum culture for fungus
• Aspergillus skin test
18

18. CHEST RADIOGRAPHY
• Dilated and thickened airways (tram‐tracking or parallel lines)
• Irregular peripheral opacities that represent
mucopurulent plugs
• Loss of lung volume and peribronchial fibrosis
Cystic fibrosis ‐ upper lobes
Allergic bronchopulmonary aspergillosis ‐ Centrally located
bronchiectasis
Bronchopulmonary sequestration ‐ lower lobe and usually
unilateral
19

19. IMAGING ‐ CT
• Most sensitive ‐to detect bronchiectasis ‐
high resolution computed tomography (HRCT)
• Internal diameter of airway ‐ larger than
diameter of adjacent artery
• Airway wall thickening ("signet ring" shadows)
with or without air fluid levels
• Volume loss, mucus plugging and air trapping
20

20. MEDICAL TREATMENT
Control infection
Physiotherapy
Nutritional support
Identify etiology and treat accordingly
21

21. MEDICAL MANAGEMENT
22
• Immediate
– Medical treatment
– Postural drainage
– Relief of atelectasis
– Treatment of associated problems
• Long term
– Continuation of postural drainage

22. Treatment –any identified underlying disorder Therapy
• reduce airway secretions
• facilitating their removal ‐ with chest physiotherapy &
mucolytic agents
Pharmacotherapy
• to improve mucociliary clearance. Antibiotics
• prevent & treat recurrent infections
• Surgery‐ if localized disease ‐may be considered.
MEDICAL MANAGEMENT

23. CHEST PHYSIOTHERAPY
• Facilitate mucous expectoration ‐ manual and
mechanical interventions
• Chest percussion
• Vibration
• Postural drainage
• Cough‐assist devices & airway oscillation‐serve as
adjuncts to cough (most effective and efficient
manner of clearing airway) .
24

24. SURGICAL TREATMENT
 Only in unilateral disease
 Removal of affected segment/ lobe/lung
 Surgery contraindicated if bilateral disease
 Unilateral ‐ surgical resection ‐ good prognosis
25

25. COMPLICATIONS
• Broncho‐ pneumonia
• Empyema
• Lung abscess
• Hemoptysis
• Metastatic abscess‐brain
• Osteomyelitis
• Hemoptysis
• Cor pulmonale
• Amyloidosis
26

26. PREVENTION OF BRONCHIECTASIS
• Childhood immunization for measles and pertussis
• Screening for tuberculosis and treatment wherever needed
• Aggressive appropriate therapy of lower respiratory tract infections
• Therapy of child with chronic or recurrent respiratory problems
due to recurrent aspiration and/or gastroesophageal reflux
disease
27

27. PROGNOSIS
• Overall ‐ prognosis – good
• Progressive bronchiectasis from underlying disease
or ongoing pulmonary insult –causes progressive
obstructive defect & ultimately, respiratory
compromise
28

28. Nursing Management
• Alleviating symptoms and assisting the patient to clear
pulmonary secretions.
• Health education – Cessation of Smoking and removal other
factors that increase the production of mucus. The patient and
family are taught to perform postural drainage and to avoid
exposure to others with upper respiratory and other infections.
• If the patient experiences fatigue and dyspnea, strategies to
conserve energy while maintaining as active a lifestyle as
possible.
• The patient needs to become knowledgeable about early signs
of respiratory infection and the progression of the disorder so
that appropriate treatment can be implemented promptly.
• Because the presence of a large amount of mucus may
decrease the patient’s appetite and result in an inadequate
dietary intake, the patient’s nutritional status is assessed, and
strategies are implemented to ensure an adequate diet.
