When infection occurs after stitches in the finger, the stitches should be removed and drained according to the local situation. If an abscess has formed, it is recommended that all stitches be removed and drained to fully remove the pus from under the skin, and that the secretions be taken for bacterial culture and drug sensitivity testing, with antibiotics administered according to the results of the drug sensitivity test. Wound irrigation, drainage, and appropriate dilation should be performed regularly every day to remove necrotic tissue and abscesses. At the same time, the affected limb should be elevated appropriately to promote venous return, and anti-inflammatory and analgesic drugs and drugs to improve local soft tissue circulation can be used to promote inflammation. With the use of sensitive antibiotics and regular debridement and dressing changes, the wound infection can be basically controlled and can gradually heal.
