Treatment of Pleural Empyema in Community-Acquired Pleural Infection (No Penicillin Allergy)
This protocol applies to patients presenting with community-acquired pleural infection who have no penicillin allergy. In this setting, the infecting organisms are not yet identified and empirical therapy must account for the range of pathogens typically encountered in the community.
In community-acquired pleural infection, treatment must cover both Gram-positive aerobes and anaerobes until culture results are available. The frequent co-existence of penicillin-resistant aerobic organisms and anaerobic bacteria shapes the antibiotic strategy.
Management involves empirical broad-spectrum antibiotic therapy targeting Gram-positive aerobes and anaerobes, combined with prompt intercostal drainage. The specific antibiotic regimen, route of administration, step-down criteria, and total duration are detailed in the full protocol.
The target endpoint is clinical improvement — defined as cessation of pyrexia, resolution of inflammatory markers, and radiological improvement. This guides the decision to transition between treatment phases.
