Eosinophilic pleuritis(pf eosin./total nucl. pf

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.” *

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.

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)
