ICD11: -

Bacterial, purulent inflammation of the tissue crevices, usually caused by staphylococci and streptococci.

Staphylococcus aureus and group A streptococci (rarely also mixed flora or gram-negative germs) can form unfocused abscesses and enter the bloodstream and lymphatic system via the subcutaneous tissue. This is often caused by panaritis, minor injuries, infected wounds, thrombophlebitis or erysipelas

  • Warm, pasty, painful, sometimes purulent, reddened oedema, rarely with subcutaneous abscesses. In addition, lymphangitis and lymphadenitis may occur
  • A severe feeling of illness and high fever
  • is typical
  • The diagnosis is made clinically
  • Bacterial smear after stab incision if atypical pathogens are suspected
  • BB (leucocytosis), CRP, ESR, liver and kidney values (before planned antibiotic therapy)
  • Regular control of temperature, blood sugar determination
  • Thrombophlebitis
  • Sepsis
  • Inpatient admission
  • Bed rest
  • Restraint
  • Elevation of the affected part of the body
  • Operative incision with splitting of fascia in case of fluctuation, antiseptic irrigation with e.g.: Povidone-iodine solution and drainage/flap insertion

Topical therapy

  • Moist dressings with antiseptic additives (chlorhexidine gluconate solution, quinolinol sulphate) with regular re-lubrication

Systemic therapy

  • Cefuroxime p.o. 250-500 mg 2x tgl (> 12 yrs), 125 mg 2x tgl (5-12 yrs and ≥ 15 kg); i.v. 750 mg-1.5 g 3-4x tgl

  • Alternatively: clindamycin i.v. 3x 600/d (particularly good tissue penetration)

In severe and resistant cases, hospitalisation

  • Alternative: Gentamicin 1 time/day 240 mg p.o.
  • Alternative: Ceftazidime i.v. (or i.m. (0.5 or 1 g)) 1-2 g 2-3x tgl (> 14 yrs), max. 3 g/d (> 80 yrs), 30-150 mg/kg bw/d in 2-3 individual doses (1-14 yrs), 50-100 mg/kg/d in 2 individual doses (2 m.- 1 yr), 25-60 mg/kg/d in 2 individual doses (< 2 m.)
