Is the wound necrotic if it turns purple?

I believe everyone has had the experience of being injured, but many people do not deal with minor injuries in a timely manner, causing their wounds to become more and more serious, and even become blue, inflamed, red and swollen. If you find that a person's wound is purple, there are many reasons for this. However, many people worry that their wounds may turn purple. Is it because the skin tissue around the injured area is necrotic?

1. Does the purple wound mean it is necrotic?

1. There are purple and blue bruises around the wound. These bruises are mainly caused by subcutaneous blood stasis that has not dissipated. It is recommended to apply hot compress to the affected area to promote the dissipation of subcutaneous blood stasis. Hot compress once or twice a day is fine. Be careful not to press or scratch the scab to prevent complications such as infection.

2. Purple and black discoloration around the wound may also be due to local necrosis after infection. If the latter is more serious, you should go to the hospital immediately for treatment. It is recommended to go to the hospital's surgery department in time and have the doctor check the wound. If there is purulent infection, the wound should be cleaned and bandaged in time, and the dressing should be changed regularly.

2. What to do if the wound rots

1. Superficial decay: If the patient's wound is superficially decayed, the patient's dermis has not been damaged. First, use normal saline to clean the patient's wound, remove necrotic tissue and exudate from the wound, and apply iodine to reduce inflammation of the wound. You can also take some anti-inflammatory and anti-infection drugs orally under the guidance of a doctor.

2. Deep decay: For more serious deep decay, the first thing to do at this time is to clean the wound and remove the necrotic tissue in the wound to prevent these necrotic tissues from causing worsening of the patient's wound decay. If the patient's wound tissue defect is severe, treatment can be carried out using drugs such as wound-closing prescriptions to promote rapid wound healing. Of course, during the treatment, you can also use some anti-inflammatory and anti-infective oral medications.

3. What to do after wound tissue necrosis

After the wound tissue becomes necrotic, it must be thoroughly cleaned. It usually takes about 2 weeks to remove all the necrotic tissue. You need to go to the hospital for a thorough debridement, removal of all pus clots, and then intravenous administration of anti-inflammatory drugs such as cephalosporins.
