Fournier gangrene medical therapy
Introduction
Steven C. Campbell, M.D., Ph.D.; Associate Editor(s)-in-Chief: Yamuna Kondapally, M.B.B.S[1]; Jesus Rosario Hernandez, M.D. [2]
Overview
Overview
Fournier gangrene is a urological emergency requiring intravenous antibiotics and debridement (surgical removal) of necrotic (dead) tissue. Despite such measures, the mortality rate overall is 40%, but 78% if sepsis is already present at the time of initial hospital admission.[1] The spread of gangrene is rapid at the rate of 2–3 cm/h, hence early diagnosis and emergency surgical treatment is important.[2]

Antimicrobial Therapy
- Fournier gangrene[3]
- If caused by streptococcus species or clostridia
- Preferred regimen: Penicillin G
- Polymicrobial
-
- MRSA (methicillin resistant staphylococcus aureus) suspected
- Preferred regimen: vancomycin OR daptomycin
Nutritional Support
The metabolic demands of Fournier gangrene patients are similar to those of other major trauma or burns.[4] Nutritional support to replace lost proteins and fluids from large wounds and/or the result of shock is required from the first day of a patient’s hospital admission.
Hyperbaric oxygen
- Delivery of 100% oxygen (hyperbaric) at two or three times the atmospheric pressure for 30 to 90 minutes with three to four treatments daily.[5]
- Hyperbaric oxygen inhibits infection and exotoxin release.[6]
- It enhances efficacy of antibiotics by increasing local oxygen tension in tissue and augment oxidative burst and killing ability of leukocytes.[7]
- These effects result in a reduced need for surgical debridement and improved morbidity and mortality in patients with necrotizing fasciitis.
Contraindications to hyperbaric oxygen are:[8][9]
- Pneumothorax
- Cisplatin (which decreases the production of superoxide dismutase which is protective against damaging effects of high partial O2 pressure)
- Doxorubicin therapy
Side effects of hyperbaric oxygen are:
- Barotrauma of the middle ear
- Seizures
- Loss of respiratory drive in hypercapnic patients (therefore, frequent periods of breathing in room air are interposed when patients are on HBOT)
- Vasoconstriction
IV γ-globulin
- Use of intravenous immune globulin is not FDA approved.
- If used, this treatment is restricted to critically ill patients with either staphylococcal or streptococcal infections.[10]
