Management of Breast Infections with Persistent Fever

Initial Assessment and Surgical Intervention

• Opening infected wounds is essential, as antibiotics alone without drainage show no clinical benefit for established abscesses 1
• If necrotizing infection is suspected, obtain immediate surgical consultation, as this is a surgical emergency with high mortality if delayed 3, 2

Red Flags for Necrotizing Infection

• Pain disproportionate to physical findings is the most important early sign of necrotizing infection 2
• Look for hard, woody texture of subcutaneous tissue, edema or tenderness extending beyond visible erythema, skin necrosis, bullae, or crepitation, which are indicative of necrotizing infection 2

Antibiotic Management

• Broaden antibiotic coverage empirically if not already done, as persistent fever suggests resistant organisms or inadequate spectrum 3
• For breast infections with systemic toxicity, consider coverage for MRSA and anaerobes with vancomycin or linezolid plus piperacillin-tazobactam 3, 2
• Obtain wound cultures before any antibiotic changes to guide definitive therapy 1

Common Pitfalls

• Do not continue the same antibiotics without drainage if an abscess is present, as this approach has no evidence of benefit 1
• Do not delay surgical evaluation waiting for antibiotics to work when fever persists beyond 3-5 days 4, 5
• Do not assume all breast infections are simple mastitis, maintain high suspicion for necrotizing infection, especially with systemic toxicity 3, 2
