2. ACUTE BRONCHITIS.
Acute bronchitis is an inflammation of the bronchi in the
lower respiratory tract. The inflammation also involves the
mucous membrane of the trachea.
Acute bronchitis typically lasts less than 10 days, but the
coughing can continue for several weeks.
3. CAUSES OF ACUTE BRONCHITIS:
Viral infection (85 to 95 percent)
Bactertial infection (Mycoplasma pneumoniae
, Chlamydia pneumoniae, and Bordetella pertussis ).
Smoking
Elderly people being very susceptible;
Malnutrition
Air pollutions
Poor ventilation
Overcrowding
Occupations exposures whereby irritant particles are
inhaled,
4. RISK FACTORS
Factors that increase your risk of acute bronchitis
include:
Cigarette smoke , including secondhand smoke
Weakened immune system
Gastric reflux
Frequent exposure to irritants, including dust or
chemical fumes
Lack of vaccinations for the flu, pneumonia, and
whooping cough
Age older than 50 year
5. PATHOPHYSIOLOGY
Due to etiology
Inflammation of mucous membrane of the trachea
and bronchi , later it become congested and
swollen
But soon becomes opaque, and finally muco-
purulent.
swelling of the mucous glands & smaller bronchial
tubes are dilated.
Mucosa becomes infiltrated with leukocytes causes
narrowing of bronchi.
6. CLINICAL MANISFESATION
Common cold
Throat is dry and rough , sore throat
Voice is hoarse.
Fever (100°F to 100.4°F (37.7°C to 38°C)
Cough with expectoration
Dull pain in the chest.
Wheezing
Malaise
Generalised weakness.
Coated tongue
Headache.
7. DIAGNOSTIC STUDIES
History collection
Physical examination : Chest auscultation
( Rhonchi sounds).
Chest x-ray
Sputum analysis.
Arterial blood gas studies..
Spirometry
Pulmonary function test
CT / MRI Chest
9. MANAGEMENT
Symptomatic Management
NSAID’s (Analgesics) & Anti-inflammatory
:Ibuprofen and Naproxen
To relieve pain , reduce fever& inflammation. Cough
suppressants.
Corticosteroids: prednisolone. To control inflmmation.
Antibiotics: Based on causative agent.(Amoxicillin,
Oxytetracycline or Doxycycline.)
Bronchodilators. Ipratropium , Theophylline
10. Oxygen Therapy
Nebulization. (Albuterol)
Steam inhalation.
Nutritional diet.
Surgery: Lung transplant is optional in case lung
is severe damaged
11. NURSING DIAGNOSIS
Impaired gas exchange related to
obstructed airways.
Ineffective breathing pattern related to
excess mucus production.
Activity intolerance related to
breathlessness.
12. NURSING CARE.
Check Respiratory status of the patient.
Provide comfortable bed & position.
Monitor vital signs & spo2
Encourage ambulation, coughing, and deep
breathing.
adequate fluid intake to liquefy secretions.
Encourage rest, avoidance of bronchial irritant.
Administer oxygen & medications as ordered.
14. CHRONIC BRONCHITIS
A repeated inflammation of the mucous membrane
of the trachea and bronchi, that causes continuous
irritation & swelling of airways.
Causes
Pneumonia
Organic heart disease
Rheumatism
Syphilis
Tuberculosis
Chronic alcoholism
Chemical irritants.
15. CLINICAL MANIFESTATION
Cough, the expectoration
Difficulty in breathing, causing
exhaustion
Fever with chills
Tachypnoea
Tachycardia
Tight chest
16. DIAGNOSTIC STUDIES
History collection
Physical examination.
Pulmonary function test
Chest x-ray
Computed tomography of chest
Arterial blood gas studies.
Sputum studies
Complete blood count: WBC count
Blood culture.
17. MANAGEMENT
Same as acute bronchitis…… Additionally
Oxygen therapy
Anti-inflammatory agents: Steroids.
Antibiotics: Based on agents
Antipyretics.
Branchodilator.
Nebulization
Steam inhalation.
18. NURSING MANAGEMENT
Provide comfortable bed & position
Assess vital signs ( Spo2, Pao2, Paco2)
Administer oxygen if required.
Provide well balanced diet
Health education on personal hygiene , medication
,Follow-up care.
Deep breathing & coughing exercises.
Steam inhalation
