Skin and soft tissue purulent infection symptoms and signs
- Redness, swelling, increased skin temperature, tenderness, sclerosis, lumps, or concentric spreading red pain strips, whether there is local fluctuation, necrosis, ulcers and dysfunction, etc. Pay attention to whether the regional lymph nodes are enlarged. Whether the same lesions exist in other parts of the body. Active hand and foot tinea.
Diagnosis of skin and soft tissue purulent infections
History of skin and soft tissue purulent infections
- Ask whether the affected area has redness, swelling, heat, pain, its occurrence and development, whether it has fever and its extent, and whether it has suffered local trauma before onset. In addition, you should also pay attention to asking for hand and foot tinea; varicose veins of the lower extremities and their degree; and history of tuberculosis and diabetes.
Skin and soft tissue purulent infections
- Localized swelling, increased skin temperature, tenderness, induration, lumps, or concentric spreading red pain strips, localized fluctuations, necrosis, ulcers, and dysfunction. Pay attention to regional lymph nodes for swelling. Whether the same lesions exist in other parts of the body. With or without active hand and tinea pedis.
Skin and soft tissue purulent infection test
- Check the blood routine, check the blood sugar if necessary, because the patients with diabetes are prone to skin and soft tissue infections.
Special examination of skin and soft tissue purulent infections
- When diagnosis is difficult, ultrasound and / or diagnostic puncture may be performed. Deep abscesses must exclude tuberculous abscesses, aneurysms, and tumors.
Skin and soft tissue purulent infections bacteriological examination
- When the general treatment effect is not good, wound secretion and abscess puncture fluid smear examination, bacterial culture and drug sensitivity test should be performed. Anaerobic bacteria culture if necessary. When septicemia is suspected, blood culture and drug sensitivity tests should be performed.
Skin and soft tissue purulent infections treatment options
Skin and soft tissue suppurative infections
- braking and raising the affected limb;
- Physical therapy such as local hot compress or supplemented with ultraviolet radiation;
- external application of Chinese medicine;
- closed therapy;
- radiation therapy;
- Those who have locally purulent ulcers should be changed appropriately.

- The drug was discontinued 3 days after the body temperature and blood returned to normal. Penicillin and aminoglycoside drugs can be used. In severe cases, cephalosporins of the second and third generation can be given. When mixed infection with anaerobic bacteria is suspected, anti-anaerobic drugs such as metronidazole can be added. If necessary, adjust the use of sensitive drugs according to the results of bacterial drug sensitivity tests.
Incision and drainage of skin and soft tissue purulent infections
- When an abscess is formed, incision and drainage should be performed in time. When incision and drainage, the following matters must be paid attention to:

- The drainage should not be too tight (unless the wound is bleeding), so as not to hinder the drainage, and it should be properly fixed, and its number and location should be accurately recorded.
- When incision and drainage, the two ends of the incision should be a little more than the edge of inflammation to reach the deep fascia.
Skin and soft tissue purulent infections Thorough debridement and removal of necrotic tissue
- For some serious special infections, such as necrotizing fasciitis, streptococcal necrosis, etc., extensive debridement should be performed, the skin should be opened and the free flaps should be fully submerged, and the skin, subcutaneous and fascial necrotic tissue should be removed as far as possible.
