In any case, there is a very high risk of self-suturing the wound, which may lead to infection, tissue necrosis, scar hyperplasia and even more serious complications (such as tetanus, sepsis, etc.). Professional medical treatment is the best choice to ensure the safe healing of wounds. The following are important suggestions： ###️ Absolutely prohibited behavior 1. **Do not use household sewing needles, glue or other non-sterile items for stitching** - Ordinary sewing needles, thread or glue (such as 502 glue) will introduce bacteria and cannot meet the standards of medical suture materials. 2. **Avoid relying on online tutorials or non-professional guidance** -Suture requires a sterile environment, anatomical knowledge and skills, and it is easy to make mistakes by yourself. ###临时 Temporary emergency measures that can be taken If you cannot seek medical attention immediately, follow these steps： 1. **Hemostasis** -Press the wound directly with a clean gauze/cloth for 10-15 minutes. 2. **Clean the wound** - Rinse gently with saline or clear water to remove foreign objects (avoid direct contact with the wound by alcohol/hydrogen peroxide). 3. **Protect the wound** -Apply an antibacterial ointment (such as Baidobang) and cover with a sterile dressing or clean gauze. 4. **Fixed edge** -If the wound is small and the edges are neat, medical wound closure tape (such as Steri-strips) can be used to temporarily close it, but signs of infection need to be checked daily. ### 🚑 Circumstances where medical attention must be sought If you have any of the following conditions, you need to go to the hospital immediately： -The wound is deep, long (>1cm) or bleeding profusely -Located in sensitive areas such as the face, joints, hands, etc. -Scratched by dirt/metal (debridement + tetanus vaccine required) -Symptoms of infection such as redness, swelling, suppuration, fever, etc. ### 重要 Important reminder Even if the wound seems minor, self-suturing may mask internal damage. Please be sure to contact a medical institution or call an emergency number for professional help. Your health and safety are far more important than saving time or money.
