1. Lung abscess is a bacterial infection in the lung tissue that causes pus to collect in dead tissue. It is challenging to treat and can be life-threatening. 2. Occupational lung diseases result from inhaling dust or chemicals at work. Pneumoconiosis like silicosis and asbestosis are caused by inhaling mineral dust and cause scarring of lung tissue. 3. Other occupational lung diseases include hypersensitivity reactions like asthma from allergens at work, and byssinosis from cotton dust exposure without proper ventilation. Prevention focuses on protective equipment and measures to reduce exposure.

2. Lung Abscess
• A lung abscess is a bacterial infection that
occurs in the lung tissue.
•The infection causes tissue to die, and pus
collects in that space.
•A lung abscess can be challenging to treat,
and it can be life-threatening.

3. Etiology of Lung Abscess:
 In many cases the causes & pathogenesis is similar to
pneumonia
 The more commonest causes is aspiration of materials
into the lung &
Risk Factors Are:
 Alcoholism, seizures disorders, drug overdose,
 Infections: Klebsiella, S. aurous, anaerobic bacilli.
 Secondary result from hematogenously: pulmonary
embolism, malignant growth, TB & fungus & parasitic
diseases of lung

4. Pathophysiology of Lung Abscess

5. Clinical Manifestation of Lung Abscess
 On P/E: dullness on percussion, decrease breath
sound on auscultation
 Muco purulent cough (brown color) with foul
smelling
 Hemoptysis especially at the time of abscess
rupture
 Fever, chill
 Pleuritic pain, dyspnea, cough & weight loss
 Crackle may present
 Oral infection: dental caries, gringivitis

6. Diagnosis of Lung abscess
History taking/Physical Examination
Chest X-ray
Sputum C/S
Bronchoscopy
Ct Scan
 MRI

7. Medical Management of Lung Abscess
 Antibiotics: Penicillin G, Pen-V & clindamycin
 If antibiotic is failed & fever and other symptoms continue
after 10-14 days of after treatment & x-ray shows abscess
is not shrinking surgical treatment is needed.
 In surgical treatment removal of abscess of insertion of tube
to drain the abscess.
 Chest physiotherapy & postural drainage
 Maintain oral hygiene, rest & good nutrition
 Adequate fluid intake

8. Nursing Management Of Lung Abscess
1. Assessment:
Cough with smell, color, odor
Pain
Temperature, malaise
Breathing patterns
Oral hygiene
Nutritional level
Sleeping patterns
Activity intolerance

9. Nursing Diagnosis of Lung Abscess
 Hyperthermia related to direct effects of circulating
endotoxin on the hypothalamus
 Ineffective airway clearance related to bronchoconstriction,
increased production of secretions, retained secretion
 Impaired gas exchange related to oxygen disruption &
damage to the alveoli
 Pain related to pulmonary parenchymal inflammation,
retained cough
 Activity intolerance related to imbalance between supply &
demand of oxygen, general weakness
 Knowledge deficit related to lack of information,
misunderstanding about information, cognitive limitation

10. Occupational Lung Diseases
• Occupational or environmental lung disease result
from inhaled dust or chemicals.
•The duration of exposure & amount of inhalation
has a major influence whether the individual will
have lung damage & another factors is the
susceptibility of host.

11. Etiology of Occupational lung diseases
 Blue collar workers (Labor jobs) than white collar-
workers (office setting jobs)
 Industrial area than the rural areas
 Small & medium sized business than in large
industrial plants
 Fungi & bacteria: working in swimming pool,spa
 Farmers, mushroom workers,

12. Types of occupational lung diseases
 The pneumoconiosis (black lung disease)
 Asbsestos-related lung diseases
 Hypersensitivity diseases
 Byssinosis (brown Lung diseases)

13. 1. Pneumoconiosis
– Pneumoconiosis is also known as “dust in the lungs”
through inhalation & retention of dust particles.
i) Silicosis ii) Asbestosis iii) Byssinosis
Its types are

14. i) Silicosis:
• It is a condition caused by inhaling too much silica over
a long period of time.
• Silica is a crystal-like mineral found in sand, rock, and
quartz
• silica dust particles act as tiny blades on the lungs.
• These particles create small cuts that can scar the lung
tissue when inhaled through the nose or mouth.
• Scarred lungs do not open and close as well, making
breathing more difficult.
• The U.S. Department of Safety says silica is a
“carcinogen” that can cause cancer including lung
cancer.

17. There 3 level of silica exposure:
Acute Accelerated Chronic
• Acute silicosis
forms a few weeks
or months after
high levels of silica
exposure.
•This condition
progresses
rapidly.
• Accelerated
silicosis comes on
5 to 10 years after
exposure.
• Chronic silicosis
occurs 10 years or
more after silica
exposure.
• Even low
exposure levels
can cause chronic
silicosis.

18. Clinical Feturses of silicosis
 Breathlessness, weakness, chest pain, productive
cough
 May die due to corpulmonale & respiratory failure
Prevention of silicosis
Use of special suits and breathing apparatus

19. 2. Asbestos-related lung diseases
(Asbestosis)
• A soft, greyish-white material that does not burn,
used especially in the in buildings, clothing, protection
against fire.
• Asbestosis is a chronic inflammatory & fibrotic condition
which affects lung tissues caused by inhalation & retention of
asbestos fibers.
• It commonly seen in people who works in mining,
manufacturing, handling or removal of asbestos.
• Asbestos caused lung cancer, malignant mesothelioma( CA
of pleura and peritoneal membrane) cancer of the larynx, &
certain gastrointestinal cancer.

20. Clinical Features of Asbestosis
 Shortness of breath during physical activities
 May lead respiratory failure
 Reduce vital capacity (total lung capacity)
 Right side heart failure
 Cor-pulmonale
 Low O2 capacity in the blood arteries.
Prevention of Asbestosis
 Use of protective mask during work
 Pneumonia vaccine: help in the reduction of lung infection.
 Using the vacuum cleaner or wet rags rather than
sweeping
 Using protective face mask

22. Hypersensitivity Diseases
• It is also called as hypersensitivity reaction or intolerance.
• It is a set of undesirable reaction produced by normal
immune systems including allergies, occur in bronchi,
bronchioles or alveoli.
a)Occupational Asthma
•Hypersensitivity reaction caused by histamine & caused
bronchoconstriction & increased mucus production.
•Repeated attack, if caused unrecognised & asthma is
untreated may lead to COPD.

23. Risk Factors of occupational Asthma
 House dust, cigarette smoke
 Working in: animals handler, veterinarians, millers e.g.
cereal, grains, carpet maker, carpenters, hairdressers,
health care workers, pharmaceutical worker
Sign & symptoms:
 Fatigue, wheezing during night
 Coughing, SOB, chest tightness
 Runny nose, nasal congestion
 Eye irritation & tearing

24. Byssinosis (Brown lung diseases)
•It is also called "brown lung disease" or “Monday
fever",
• It is an occupational lung disease caused by
exposure to cotton dust in inadequately ventilated
working environments.
• It's caused by the inhalation of raw flax, hemp,
cotton dust, and similar materials.

26. Coal worker's pneumoconiosis or black
lung disease
• This disease is caused by inhaling coal dust.
• It causes inflammation and scarring of the lungs.
• This can cause permanent lung damage and
shortness of breath.

28. Diagnosis
• Chest X-ray
• Pulmonary function tests (PFTs)
• Bronchoscopy: this test uses to view the bronchi & helps
to diagnose lung problems, for blockages.
• Lung biopsy
• Blood tests
• CT scan: it can be used to diagnose lung diseases,
monitor disease progression, and evaluate response to
treatment.

29. Management of occupational lung
diseases
 There is no specific treatment for occupational lung
diseases treatment is based on sign & symptoms
 The best approach to management is to prevent
environmental or occupational risks
 Effective ventilation, wearing mask, protective measures
 Cigarette smoking must be avoided
 Early diagnosis and treatment
 Periodic chest x-ray and pulmonary function test for
vulnerable people
