Hand infection symptoms and signs

Swelling, tenderness, pain worsening when straightening fingers. Hand skin ulceration or sinus tract, forearm concentric spreading red tenderness stripes, lymphadenopathy and tenderness on the pulley and axillary.

Causes of hand infections

Injury history.

Hand infection diagnosis test

1. Ask if there is a history of trauma to the hand, especially the slight stab wound.

2. Pay attention to the location, scope and extent of the swelling, the position of the hand, the tender spot and the most painful point, and whether the pain worsens when you straighten your fingers.

3. Pay attention to whether there is ulcer or sinus in the skin of the affected hand. If there is secretion, it should be smeared, bacterial culture and antibacterial sensitivity test.

4. Whether the forearm spreads red tenderness streaks concentrically, whether there is swelling and tenderness on the pulley and axillary lymph nodes. Treatment plan (View content) (I) Treatment

Early processing

(1) Inflammation has not been limited, and the abscess has not yet formed. The affected hand should be raised and braked to rest fully. When the patient is standing, the forearm is suspended and fixed with a triangle towel; when lying, the affected limb is raised by about 45 ° with a pillow or a ramp.

(2) The affected hand can be dipped in hot or hot water for 2 ~ 3 / d for 20min each time; or other physical therapy can be applied.

(3) Give sedatives or analgesics as appropriate.

(4) antibiotics are given. Most of the pathogenic bacteria of hand infection are staphylococci or streptococcus. Penicillin or other commonly used antibiotics can be used.

2. Management of hand infection and abscess formation

(1) After the abscess has formed, it should be opened and drained as soon as possible.

(2) A large amount of antibiotics should be given before incision and drainage for 1 h, which can help prevent the spread of infection that may be caused by surgical procedures.

(3) Anesthesia requirements: Anesthesia must achieve sufficient pain relief. For general purulent fingeritis, paronychia, and hypothyroidism abscesses, 1% to 2% of procaine can be used as a digital nerve block anesthesia at the root of the finger; the infection has been extended to the root of the finger or a scholar, and brachial plexus Nerve block anesthesia or general anesthesia.

(B) postoperative management

1. Fix the patient's hand in the functional position and lift it with a sling. Raise your hands when sleeping.

2. Soak in warm sterile liquid before each dressing change.

3. Give proper antibiotics.

4. Immediately after infection control, practice automatic or passive activities to prevent ankylosis of the knuckles. After incision and drainage of tenosynovitis, early activity can reduce tendon adhesions, and physical therapy can promote functional recovery.

5. If the drainage is smooth, but the wound does not heal for a long time, check for bone or joint infections, or tendon necrosis. Make an X-ray examination if necessary.
