What is the initial treatment indicated for a patient with pleural effusion who develops empyema?

In the case of a patient with pleural effusion who develops empyema, the initial treatment involves the administration of antibiotics. Empyema is characterized by the presence of pus within the pleural cavity, typically resulting from an infection. The prompt use of antibiotics is crucial to combat the infection and prevent further complications. Antibiotics help to reduce the bacterial load, control inflammation, and assist in managing symptoms.

While procedures like chest tube insertion and thoracentesis are important in the management of pleural effusion and may help in draining pus, the primary approach is to initiate systemic antibiotic therapy to address the underlying infectious process. Fluid restriction is generally not a specific treatment for empyema and does not address the infection. Thus, starting antibiotics is essential to effectively treat the infection associated with empyema.
