Malignancy Tuberculosis Idiopathic effusion
Exudative pleural effusions pH< 7.30 (or glucose < 60
mg/dL) Diagnosis is limited to 6 causes:
EmpyemaMalignancyEsophageal ruptureTuberculous pleurisyLupus pleurisyRheumatic pleurisy
Empyema
Eosinophilic pleuritis(pf eosin./total nucl. pf
cells>10%) Pneumothorax Hematothorax Drug reactions Benign asbestos pleuritis Lymphoma, carcinoma Churg-Strauss syndrome Infections (fungal, parasitic)
> 10% eosinophils rules out tuberculosis!
> 80% lymphocytes in pf Tuberculosis Chylothorax Lymphoma Trapped lung Sarcoidosis Chronic Rheumatic pleuritis Yellow nail syndrome Post- coronary artery by pass
Tuberculous pleuritis
PPD may be negative in 30% of cases12% in HIV negative patients47% in HIV positive patients
Eosinophils > 10% rule out tuberculosis Mesothelial cells > 5% rule out TBC Pleural fluid TB culture may be positive
in only 20%
Why should you perform thoracoscopy ?
(Pleural effusions)
Thoracocenthesis
Non-diagnostic in 20-60% False-negative for malignancySpecific diagnosis rare

Diagnosis

Diagnosis ?Thoracoscopy
Blind pleural biopsy should only be performed in areas with high incidence of tuberculosis (in resource-poor countries)

Investigatepneumonia When ..plan B
Para-pneumonic effusion (PPE)?
Pleural effusion complicate 20-57% of hospitalized pneumonias
Depending on responsible organism for pneumonia
Any pneumonia should be assessed for para-pneumonic effusion
If more than minimal effusion, pleural fluid needs to be sampled.
B
Pathogens to cause infectious PE
Pathogenic organism Type
Bacteria Gram-positive aerobesGram-negative aerobesAnaerobesSpecial:Mycobacterium tuberculosisActinomycesNocardiaMycoplasma pneumoniiCoxiella burneti
Factors Associated with Poor Prognosis
( require invasive procedures) 1. Pleural fluid is pus
2. Pleural fluid bacterial smears are positive
3. Pleural fluid glucose is less than 60 mg/dl
4. Pleural fluid bacterial cultures are positive
5. Pleural fluid pH is less than 7.20 6. Pleural fluid LDH is more then three
times the upper limit of normal 7. Pleural fluid is loculated

Fibrinolytics?
“It is my recommendation that fibrinolytics should be reserved for patients in centers without access to
video assisted thoracic surgery (VATS) and for patients who are not surgical candidates.” *

Local pleural treatment options
Treatment Options
Medical Surgical
(Serial) therapeutic thoracenteses (Image guided)small bore tubesStandard chest tubes# Medical thoracoscopy (pleuroscopy)+/- fibrinolytic agents/ˇirrigation
VATS (surgical thoracoscopy)Standard thoracotomyOpen drainage (fenestration)
Loddenkemper R. et. al, Eur.Respir.Mon.,2004
Procedural approach in the local treatment of
empyema (Lungenklinik Heckeshorn) Drainage: Toracoscopic/image-guided double-lumen trocar
catheter insertion, 20–28F, length 40 cm. Irrigation: 1,000 mL normal saline solution 20 mL 2%
povidone iodine,until clear irrigation fluid recovered. Instillation (fibrinolysis) 200,000 IU streptokinase 50,000 IU
streptodornase, tube clamped 4–8 h (tolerance dependent). Duration 14 days Side effects Fever> 38 C (42%), pain (10%) Precautions Postural maneuvers (diseased side in
dependent position), no bronchial- pleural fistula, no allergy.

Insertion of multiple chest tubes Intrapleural administration of fibrinolitics Thoracoscopy Decortication Open drainage procedure
Options?
VATS is prefered
Evidence based guidelines of PPE treatment (ACCP)
PPE should be considered in all pneumonia (C) Drainage of PPE should be based on estimated
poor outcome risk (D) Risk 1 and 2 may not require drainage (D) Drainage recommended in risk 3 , 4 category (D) Therapeutic thoracentesis or tube thoracostomy
alone appears insufficient in most of risk 3, 4 (C); reevaluation after several hours is useful (D)
Fibrinolytics, VATS and surgery are acceptable approaches in risk 3, 4 categories (C)
