Management of Infected Wounds in Calciphylaxis

Immediate Surgical Intervention

The Infectious Diseases Society of America recommends performing aggressive surgical debridement immediately to remove all necrotic tissue, eschar, and infected material, as this is the cornerstone of management and should not be delayed, with multiple staged procedures possibly necessary given the extensive nature of calciphylaxis wounds 1, 2
The American College of Surgeons suggests that debridement should be performed without delay, even if revascularization or other procedures are planned, as immediate removal of necrotic infected material is critical 1, 2

The American College of Cardiology recommends initiating broad-spectrum parenteral antibiotics immediately for all infected calciphylaxis wounds, as these patients are at extremely high risk for sepsis and death 3, 4
The Infectious Diseases Society of America suggests obtaining deep tissue cultures via biopsy or curettage from the debrided wound base before starting antibiotics when possible, but not delaying treatment if the patient is systemically ill [4, @18@]
The Society for Healthcare Epidemiology of America recommends avoiding superficial swabs of undebrided wounds as they provide inaccurate results [4, @18@]
The American College of Clinical Pharmacy suggests that empiric coverage should target aerobic gram-positive cocci, gram-negative organisms, and anaerobes given the polymicrobial nature of these chronic, necrotic wounds 5, 4
The Infectious Diseases Society of America recommends considering MRSA coverage if the patient has prior MRSA history, high local prevalence, or severe systemic infection 4, 6
The American College of Physicians suggests continuing antibiotics until clinical resolution of infection, not necessarily until complete wound healing—typically 2-4 weeks for severe soft tissue infections depending on adequacy of debridement 5

The Wound, Ostomy, and Continence Nurses Society recommends implementing meticulous daily wound care, including dressing wounds to maintain a moist healing environment while allowing daily inspection 1, 2
The American College of Surgeons suggests avoiding topical antibiotics—there is insufficient evidence they improve outcomes in infected wounds 7, 1

The Society for Vascular Surgery recommends evaluating arterial perfusion urgently, and if significant arterial stenosis is identified, performing revascularization within 1-2 days rather than relying on prolonged antibiotic therapy alone for severely infected ischemic wounds 1, 2

The American College of Emergency Physicians recommends following patients with infected calciphylaxis wounds daily if hospitalized or every 2-5 days as outpatients initially to ensure treatment efficacy 1, 4
The Infectious Diseases Society of America suggests monitoring for progression of infection, systemic signs of sepsis, and adequacy of debridement 5, 4
The American College of Physicians recommends hospitalizing patients with severe infection, systemic toxicity, extensive necrosis, or inability to comply with outpatient management 4
The American College of Surgeons suggests watching for complications including deep abscess formation, osteomyelitis, septic arthritis, and necrotizing fasciitis which require urgent surgical consultation 5

The American College of Surgeons recommends avoiding inadequate antibiotic coverage—these are polymicrobial infections requiring broad-spectrum therapy 5, 4
