[Purulent pleurisy and empyema. With the exception of pleural tuberculosis].

CLINICAL

SETTING

Purulent collections in the pleural cavity usually occur as complications of pneumonia in immunodeficient or socially underprivileged patients.

PUNCTURE ASPIRATION: The key to diagnosis, pleural aspiration is indicated in case of sufficiently abundant collections, especially in patients with fever. Exploratory puncture is a therapeutic emergency, allowing optimal antibiotic therapy when a causal germ is isolated and drainage of the purulent collection. If there is the slightest doubt, imaging techniques should be used to guide the puncture.

DRAINAGE: Drainage is essential and is indicated whenever the aspiration fluid is purulent, contains, germs or the chemistry suggests major bacterial colonisation (acid pH, low glucose, high lactic acid dehydrogenase). Local injections of fibrinolytic agents improve drainage.

PROGNOSIS: Complete recovery without sequellae is usually achieved. Physical therapy, provided early and for a prolonged period, helps improve the prognosis. Early care reduces the risk of recurrence of this potentially severe condition.
