Management of Cellulitis with Blistering and Heavy Drainage

Wound Care Principles

• Elevation of the affected extremity is essential to promote gravitational drainage of edema and inflammatory exudate, which hastens clinical improvement in cellulitis 1
• The American College of Physicians and other guideline societies recommend inspecting the wound bed daily for signs of worsening infection, including increased purulence, expanding erythema beyond marked borders, or systemic symptoms requiring antibiotic adjustment 2, 1

Antibiotic Coverage

• Appropriate systemic antibiotic therapy is the primary treatment for cellulitis, with beta-lactam monotherapy recommended for typical non-purulent cellulitis for 5 days if clinical improvement occurs, as suggested by the Infectious Diseases Society of America 1
• The Infectious Diseases Society of America recommends adding MRSA-active coverage with clindamycin, trimethoprim-sulfamethoxazole plus a beta-lactam, or doxycycline plus a beta-lactam if purulent drainage develops or MRSA risk factors are present 1
• Treating predisposing conditions such as tinea pedis, venous insufficiency, and lymphedema is essential to prevent recurrence, as recommended by the Clinical Infectious Diseases society 2, 1
