Background

  • MRSA is the most common cause of purulent skin and soft-tissue infections.[1][2][3]

Clinical Features

  • Tender nodular region with surrounding induration
  • Fluctuance
  • Surrounding erythema

Differential Diagnosis

  • Cyst
  • Vascular malformation

Skin and Soft Tissue Infection

Look-A-Likes

Evaluation

Fluctulance on exam
Abscess on ultrasound
  • Clinical exam: fluctulance +/- erythema
  • Soft tissue ultrasound can differentiate between abscess and cellulitis
    • Assess for fluid collection and swirl within the collection

Management

  • Incision and drainage
  • Packing
    • Abscess >5 cm in diameter
    • Pilonidal abscess
    • Abscess in an immunocompromised or diabetic patient
  • Alternative to packing is loop drainage technique with vessel ties[4] or cut the proximal cuff of the sterile gloves[5]
    • Failure rate of 4.1% for loop vessel technique vs 9.8% for conventional packing. [6]
    • Other advantage is don’t have to keep coming back to the ER for painful repacking.
    • Home Care (copied from Pediatric EM Morsels)[7]
      • Keep area clean.
      • Can cover with gauze to absorb the residual drainage.
      • Can shower and/or bathe.
    • The loop drain can be removed when (copied from Pediatric EM Morsels)[8]
      • Drainage has stopped.
      • Cellulitis has improved.
      • Usually is within 7-10 days.
  • Antibiotics
    • Although withholding antibiotics is part of Choosing wisely ACEP, new evidence suggest antibiotic NNT of 14 to prevent 1 treatment failure[9]
    • TMP/SMX DS BID x 5 days (all abscesses)[10]
    • Consider more aggressive antibiotic treatment if concomitant cellulitis

Disposition

Admission

  • Reserved for significantly ill patients or those requiring surgical intervention

Discharge

  • Appropriate for majority of patients
    • Follow up in 2 days for wound check
