Sub-Category:

Transudative Pleural Effusion

Symptoms:
shortness of breath; chest pain; cough; reduced breath sounds on the affected side; dullness to percussion on physical exam

Root Cause:
An imbalance between hydrostatic and oncotic pressures, often due to conditions such as congestive heart failure (CHF) or hypoalbuminemia.

How it's Diagnosed: videos
Chest X-ray, ultrasound, CT scan, and thoracentesis (analysis of pleural fluid to confirm low protein and lactate dehydrogenase levels consistent with transudate).

Treatment:
Treating the underlying cause (e.g., diuretics for CHF, correcting hypoalbuminemia) and therapeutic thoracentesis if symptomatic relief is required.

Medications:
Diuretics, such as furosemide , are commonly prescribed to manage fluid overload in cases of CHF. Albumin infusions may be used if hypoalbuminemia is present.

Prevalence: How common the health condition is within a specific population.
Common among patients with chronic heart failure and liver or kidney disease; precise prevalence varies by population and comorbidities.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Congestive heart failure, nephrotic syndrome, liver cirrhosis, and hypoalbuminemia.

Prognosis: The expected outcome or course of the condition over time.
Good when the underlying condition is effectively treated, but recurrence is possible if the primary cause is not addressed.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Risk of lung compression, secondary infections, and respiratory failure if untreated.

Exudative Pleural Effusion

Specialty: Pulmonology

Category: Pleural Diseases

Sub-category: Pleural Effusion

Symptoms:
shortness of breath; pleuritic chest pain; cough; fever if infection is present; reduced breath sounds and dullness to percussion

Root Cause:
Inflammation or infection of the pleura causing increased capillary permeability, often associated with conditions like pneumonia, malignancy, or pulmonary embolism.

How it's Diagnosed: videos
Chest imaging (X-ray, ultrasound, CT scan) and thoracentesis with pleural fluid analysis showing high protein, high lactate dehydrogenase, and possible infection markers.

Treatment:
Treatment of the underlying cause (e.g., antibiotics for infection, chemotherapy for malignancy) and drainage via thoracentesis or chest tube placement if needed.

Medications:
Antibiotics (e.g., ceftriaxone for bacterial pneumonia), corticosteroids for inflammatory causes, and chemotherapy or targeted agents for malignancy-related effusions.

Prevalence: How common the health condition is within a specific population.
Varies depending on underlying conditions; common in cases of pneumonia, cancer, or tuberculosis in certain populations.

Risk Factors: Factors or behaviors that increase the likelihood of developing the condition.
Lung infections, malignancy, pulmonary embolism, connective tissue diseases.

Prognosis: The expected outcome or course of the condition over time.
Depends on the underlying cause; potentially serious if not addressed promptly, particularly in malignancy or infection-related cases.

Complications: Additional problems or conditions that may arise as a result of the original condition.
Empyema (infected pleural fluid), trapped lung, and respiratory failure if left untreated.
