A hole in a wound that never heals is mainly caused by abnormalities around the wound, and the common clinical causes include infection around the wound, foreign objects, poor suture, and deviation of blood flow.
1. Infection around the wound: after infection occurs, it will lead to edema, oozing and even pus in the surrounding tissues, which will affect the wound healing.
2. Local foreign body: foreign body in the wound will cause rejection reaction, which will easily cause the local granulation tissue to proliferate and affect the wound healing.
3. Poor suture: poor postoperative suture, resulting in a decrease in the speed of local tissue repair, affecting wound healing.
4. Deviation of blood transport: local blood vessel damage, resulting in insufficient blood supply to the corresponding tissues, which will cause delayed wound healing.
If the wound does not heal and is accompanied by redness, swelling and oozing, it is necessary to consult a doctor for observation and standardized treatment under the guidance of the clinician.
