(Pleural effusions)

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.

Pathogens to cause infectious PE
Pathogenic organism
Type
Bacteria
Gram-positive aerobes
Gram-negative aerobes
Anaerobes
Special:
Mycobacterium tuberculosis
Actinomyces
Nocardia
Mycoplasma pneumonii
Coxiella burneti
Factors Associated with Poor
Prognosis

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

Anti-inflammatory drugs
Analgesic drugs
Therapeutic thoracentesis
Removal of cause(s)
Antibiotics
Drainage
Surgery
Prevention of loss of function
Early drainage

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.” *

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.

prefered
 Decortication
 Open drainage procedure

Options?
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)
