Referral for Debridement in Gangrene
Patients with gangrene should be referred immediately to a surgeon—specifically a general/emergency surgeon, vascular surgeon, or urologist depending on anatomic location—as surgical debridement must be performed as soon as possible to reduce mortality. 1, 2
Immediate Surgical Referral Algorithm
For Fournier's/Perineal Gangrene:
- Refer to general/emergency surgeons as the primary team 1
- Early involvement of urologists for evaluation of urethral or testicular involvement 1
- Plastic surgeons should be consulted where available for reconstruction planning 1
- This multidisciplinary approach is essential based on extent of perineal involvement, degree of fecal contamination, and presence of sphincter or urethral damage 1
For Extremity Gangrene with Vascular Insufficiency:
- Refer to vascular surgeons for patients with peripheral arterial disease, critical limb ischemia, or access-related steal syndrome 1, 3
- Vascular surgeons should evaluate for revascularization options, as this should be attempted first when feasible to minimize tissue loss 3
- Delay in referral can lead to catastrophic outcomes including hand amputation 1
For Gas Gangrene/Clostridial Myonecrosis:
- Urgent surgical exploration and debridement by a surgeon (general or orthopedic) is mandatory 1
- Broad-spectrum antibiotics should be started immediately, but surgery cannot be delayed 1
Critical Timing Considerations
Surgery must occur within hours, not days—early and aggressive surgical debridement improves survival and reduces the number of required surgical revisions 1, 2. The mortality rate for Fournier's gangrene averages 20-30% even with optimal management, and delayed treatment significantly increases this risk 1, 4.
Do NOT Delay Surgery For:
- Imaging studies in hemodynamically unstable patients 1, 2
- Transfer to specialized centers if local surgical capability exists 1
- Optimization of comorbidities when infection is life-threatening 1
Repeat Debridement Planning
Plan for serial surgical revisions every 12-24 hours until the patient is completely free of necrotic tissue 1, 2. The initial surgeon who performs debridement should continue managing these repeat procedures, as they understand the wound anatomy and progression 1.
Common Pitfalls to Avoid
- Referring to non-surgical specialists first (e.g., infectious disease, wound care) delays definitive treatment 1, 2
- Waiting for culture results before surgical consultation—debridement provides the most reliable cultures and should not be delayed 5
- Assuming dry gangrene doesn't need urgent surgery—any signs of infection (erythema beyond gangrenous tissue, purulent drainage, foul odor, systemic sepsis) mandate immediate surgical intervention 3, 2
- Inadequate initial debridement requiring more extensive subsequent procedures—complete removal of all necrotic tissue at first surgery reduces revision burden 1, 2
