DISEASE
CONDITI
LUNG
ABSCESS
DEFINITION
 Lung abscess is the necrosis of the pulmonary parenchyma caused
by the microbial agents/ infection.
- Brunner and Suddharth
 Lung abscess is a type of liquefactive necrosis of the lung tissue and
formation of cavities (more than 2cm) containing necrotic debris or
fluid caused by microbial infection. This pus-filled cavity is often
caused by aspiration, which may occur during anesthesia, sedation
or unconsciousness from injury.
- wikipedia
 A lung abscess is a bacterial infection that occurs in lung tissue.
- Healthline
ETIOLOGICAL FACTORS
S.N Book’s picture Patient’s picture
1. Central venous system disorder
 seizure
stroke
Not known
2. Drug addiction
3. Alcoholism
4. Esophageal disease
5. Compromised immune function
6. Patients without teeth
7. Those receiving NG tube feedings
8. Patients with an altered state of
consciousness due to anesthesia
PATHOPHYSIOLOGY
Invasion of infectious agents Defense mechanism of lungs
lose effectiveness and allow organisms to penetrate sterile lower
respiratory tract Inflammatory reaction occur
producing exudates WBC, mostly neutrophils also migrates into
alveoli and fill normally air containing spaces Areas of lung
are not adequately ventilated because of secretion and mucosal
edema partial oclusion of bronchi or alveoli
Decrease in alveolar oxygen tension, alveolar exudates tends to
consolidates so difficult to expectorate ventilation-
perfusion mismatch occurs in affected area of the lung.
CLINICAL FEATURES

illness
Productive cough with

amount, non—foul smelling
sputum

nature
3. Productive cough with
moderate to copious amount of

trhrough postural drainage and chest
physiotherapy
Tab Pcm 500mg TDS P/O
5. Insertion of percutaneous chest
catheter for long term drainage of
abcess
Tab Ifol OD P/O
6. A diet in high protein & calories Chest tube drainage
NURSING MANAGMENT
 Administration of antibiotics and iv treatment as prescribed
and monitor for side effects.
 Chest physiotherapy is initiated as prescribed to facilitate
drainage of abscess.
 Educate the patient to perform deep-breathing and coughing
exercise to help expand the lungs.
 Ensure the proper nutritional fluid intake which is high in
protein and calories.
 Administration of oxygen if necessary.
 Mobilization of patient.
 Monitor vital signs.
Contd……
 Monitor intake/output chart.
 Maintain health to prevent the complication.
 Oral care and maintain personal hygiene.
 Encourage lung expansion movements.
 Avoid over exertion and possible exacerbation of symptoms.
 Check for the site of chest-tube insertion and check for
drainage, it’s amount and color.
 Emotional support.
SURGICAL MANAGEMENT
Surgical intervention is rare, but pulmonary resection or
lobectomy is performed if massive hemoptysis (coughing of
blood) occurs or if there is no response to medical
management.
COMPLICATION
 Aspiration pneumoia
 Empyema
 Pneumatocele
 Bronchopleural fistula
 Pleurisy
 Atelectasis
 Shock & respiratory failure
NURSING DIAGNOSIS
1. Ineffective airway clearance r/t broncho constriction,
increased mucus production, ineffective cough.
2. Ineffective breathing pattern r/t mucus, broncho constriction
and airway irritants.
3. Impaired gas exchange r/t ventilation—perfusion inequality.
4. Imbalanced nutrition pattern less than the body requirement
r/t loss of appetite.
5. Activity intolerance r/t fatigue, chest tube drainage and
ineffective breathing pattern.
6. Self-care deficit r/t fatigue secondary to increased work of
breathing and chest tube insertion/
7. Insomnia r/t hospitalization as manifested by sunken eyes.
8. Deficient knowledge about the self-management. Treatment
regimen and preventive measures.
9. Risk for infection r/t prolonged hospitalization.
10. Risk for deficient fluid volume r/t rapid respiratory rate.
HEALTH EDUCATION
1) Personal hygiene
2) Diaphragmatic breathing and coughing exerrcise.
3) Self-care
4) Follow-up

CONCLUSION
A patient named Salina mahato of 20 years female diagnosed
with lung abscess with empyema thorasis was a part of my case
study, she was presented with complaints of cough with
productive yellowish colour sputum and fever for 3 days.
The case study includes detailed information, clinical
features, book picture details on disease condition, etiology,
pathophysiology, management and complications,
The case study on lung abscess with empyema thorasis
allowed me to identify the difference between the diseased and
normal client of same age group. It also provided me an
opportunity to gain knowledge. Experience and enhance the
competency.
