Pathway Overview
15 steps
Algorithm Steps
15 total
01Start 02Action Recognize Clinical Features
FG is a CLINICAL diagnosis - do not delay for imaging
- Severe perineal/scrotal pain (out of proportion)
- Rapid progression of erythema/swelling
- Crepitus (late sign - subcutaneous gas)
- Skin necrosis, bullae, ecchymosis
- Systemic toxicity: fever, tachycardia, hypotension
- Risk factors: DM, immunosuppression, obesity, alcohol
03Warning ⚠️ SURGICAL EMERGENCY
Mortality 20-40% - delay increases death risk
- Every hour of delay increases mortality
- Target: Debridement within 6-12 hours
- Do NOT wait for imaging if diagnosis obvious
- Multidisciplinary team: Urology + General Surgery + Plastics
04Action Immediate Resuscitation
Aggressive fluid resuscitation and ICU care
- IV crystalloid resuscitation (sepsis protocol)
- Correct electrolyte abnormalities
- Vasopressors if hypotensive despite fluids
- ICU admission for monitoring
- Blood/urine/wound cultures
05Action Calculate Severity Scores
Prognostic tools - do NOT delay surgery for scoring
- LRINEC Score: ≥6 suggests NF (low sensitivity ~68%)
- FGSI (Fournier's Gangrene Severity Index)
- Components: WBC, Hgb, Na, K, Cr, glucose
- Higher scores = higher mortality
- Scores aid prognosis, NOT diagnosis
06Decision Diagnosis Clear?
If obvious FG, proceed directly to OR
07Action Surgical Preparation
Prepare for extensive debridement
- Notify OR immediately
- Consent for extensive debridement
- May require diverting colostomy
- May require suprapubic catheter
- Blood products available
08Action Radical Surgical Debridement
Wide excision of all necrotic tissue
- All necrotic tissue must be excised
- Extend until healthy, bleeding tissue reached
- Multiple debridements usually required
- Re-explore in 24-48 hours
- Average 3-4 debridements per patient
- Testes usually spared (separate blood supply)
09Decision Fecal Diversion Needed?
Consider if anal sphincter involved or extensive perineal involvement
10Action Diverting Colostomy
Protects wound from fecal contamination
- Loop or end colostomy
- Facilitates wound healing
- May be temporary or permanent
11Action Post-Op Wound Management
ICU care with serial debridements
- VAC (negative pressure) therapy
- Daily wound assessment
- Re-debridement every 24-48h until clean
- Nutritional support
- Hyperbaric oxygen (adjunct, not proven)
12Outcome Wound Reconstruction
Once infection controlled - plastic surgery
- Skin grafting
- Scrotal reconstruction
- Flap coverage if needed
13Warning ⚠️ High Mortality Condition
Even with optimal care, mortality 20-40%
- Poor prognostic factors:
- - Delayed presentation
- - Diabetes mellitus
- - Extensive disease
- - Septic shock
- - Female sex (often delayed diagnosis)
- Path rejoins step 11Shared downstream outcome
14Action CT Scan (Only if Uncertain)
Do NOT delay surgery for imaging
- CT: Gas tracking along fascial planes
- Subcutaneous emphysema
- Fascial thickening, fluid collections
- Absence of gas does NOT exclude FG
- If CT equivocal but clinical suspicion high → OR
- Path rejoins step 07Shared downstream outcome
15Action Empiric Broad-Spectrum Antibiotics
Cover gram+, gram-, anaerobes, +/- MRSA
- Option 1: Pip-tazo + Vancomycin + Clindamycin
- Option 2: Carbapenem + Vancomycin + Clindamycin
- Clindamycin: Anti-toxin effect (reduces mortality)
- Add MRSA coverage (vancomycin or linezolid)
- Adjust based on culture results
- Path rejoins step 05Shared downstream outcome

Clinical Safety Information
Clinical Decision Support — Not a Substitute for Clinical Judgment
Individual patient factors may require deviation from these recommendations.
Known Limitations
- Does not replace surgical judgment for debridement extent
- LRINEC score has poor sensitivity (~68%) for FG specifically
- Individual antibiotic selection depends on local resistance patterns
- ICU management details not fully covered
- Wound reconstruction phase not addressed
Applicable Regions
USEUAU
AU: Follow local antibiotic stewardship protocols
