How is necrotizing fasciitis treated?

summary

Necrotizing fasciitis is a kind of soft tissue infection characterized by extensive and rapid necrosis of subcutaneous tissue and fascia, often accompanied by systemic toxic shock. The disease is a mixed infection of a variety of bacteria, including Streptococcus pyogenes and aerobic bacteria such as aureus and Juglans. The infection of this disease directly damages the subcutaneous tissue and fascia, and does not involve the muscle tissue of the infected site. Necrotizing fasciitis is often a mixed infection of a variety of bacteria, including Gram-positive hemolytic streptococcus, Staphylococcus aureus, Gram-negative bacteria and anaerobic bacteria. Let's share my experience with you.

How is necrotizing fasciitis treated?

With the development of anaerobic culture technology, it is confirmed that anaerobic bacteria is an important pathogenic bacteria. Necrotizing fasciitis is often the result of the synergistic effect of aerobic bacteria and anaerobic bacteria. Necrotizing fasciitis is often accompanied by systemic and local tissue immune function damage, such as secondary to abrasions, contusions, insect bites and other mild skin damage, cavity organs, after surgery, perianal abscess drainage, tooth extraction, laparoscopic operation, or even after injection (mostly in the injection of poison).

Necrotizing fasciitis, acute onset, early local signs are often hidden and do not attract the attention of patients, can affect the whole limb within 24 hours. In the early stage, the skin was red and swollen, showing purplish red flake, unclear pain, at this time, the subcutaneous tissue had necrosis, because the lymphatic pathway had been rapidly destroyed, so there were few lymphangitis and lymphadenitis. Infection can affect the whole limb within 24 hours.

Pain relieves numbness in the affected part. Due to the stimulation of inflammatory substances and the invasion of bacteria, there is severe pain in the early infected part. When the sensory nerve of the lesion or part is destroyed, the severe pain can be replaced by numbness or paralysis. Due to the destruction and blockage of nutrient vessels, the skin turns purple and black gradually, and blisters or bullae of bloody fluid appear.

matters needing attention

Subcutaneous fat and fascia edema, exudate sticky, cloudy black, and finally liquefaction necrosis. The exudate is bloody serous fluid, with peculiar odor, necrosis, extensive diffusion, latent shape, and sometimes subcutaneous gas, which can be found by examination. In the early stage of the disease, the symptoms of local infection are still mild. Patients should avoid severe systemic poisoning symptoms such as chills, high fever, anorexia, dehydration, disturbance of consciousness, anemia, jaundice, etc.
