Deep necrotizing infection of deep subcutaneous fascia

Cellulitis such as surgical wound infections can often cause bacteremia, the most serious of which is necrotizing fasciitis, deep subcutaneous fascia and progressive fatal necrotic infections. Process infections usually start from trauma (inconspicuous trauma) Or the local swelling and pain of the surgery soon spread outward. Within 24 to 48 hours, the color of the lesion changed from red to purple, and then blue to form blisters and bullae containing yellow liquid. On the 4th to 5th disease days, necrosis began to occur in the purple area, and on 7 to 10 days, the skin with clear necrosis fell off, showing extensive necrotic tissue under the skin. Patients with high fever and debilitating reactions may easily cause bacteremia and sepsis. In fact, most patients with TSLS are accompanied by severe soft tissue infections.
