If a hand cut becomes infected, the first symptoms to be detected are redness, swelling, heat, and pain, i.e., the patient feels abnormal pain, swelling, and redness of the skin around the wound, which is likely to be infected, and the patient needs to go to the hospital promptly. If the doctor finds that there is no pus accumulation in the wound and only the surface is red and swollen, usually change the medicine, clean the wound, and treat it with internal antibiotics or topical antibiotics. However, if pus or fluid accumulation is found in the wound, the doctor will usually open the wound, remove and drain the pus and fluid, and do debridement treatment. After the debridement, the wound can heal on its own after a period of dressing changes, or gradually through dressing changes, or through second-stage re-stitching to make the wound heal.
