Episode notes
Rapid Onset Case From Maggie
- Maggie described waking New Year's Eve with an intensely painful, rapidly spreading arm infection that progressed to septic shock.
- She underwent multiple surgeries, a wound vac, and IV antibiotics after cultures grew group A strep and survived with long recovery.
Fascia Acts As A Highway For Spread
- Necrotizing fasciitis spreads along fascial planes with low blood supply, allowing rapid, wide progression with little immune access.
- That 'highway' effect explains why small wounds can lead to extensive deep tissue necrosis quickly.
Toxins Drive Vascular Shutdown
- Tissue necrosis results from bacterial toxins and overwhelming inflammation that damage blood vessels, causing microthrombi and ischemia.
- Different bacteria produce distinct toxins, but the final common pathway is vascular thrombosis and necrosis.
