The degree of contamination of the wound itself has a lot to do with whether infection occurs in the future. A widely accepted method for classification of wounds is as follows:

1.Clean-Wounds

No inflammation

Did not enter the digestive, reproductive, and urinary tracts.

Completely sutured wound; if drainage is available, use a sealed drainage.

Non-penetrating wounds.

2. Clean-Contaminated Wounds

Enter the respiratory tract, digestive tract, reproductive tract, urinary tract and other pipes without special contaminated surgical wounds.

No infectious biliary, appendix, guide, oropharyngeal surgical wounds.

There was no significant contamination during the procedure.

3. Contaminated Wounds

Open, new, unexpected wounds.

The contents of the gastrointestinal tract have obvious overflow, and there is obvious pollution in the surgical process.

Acute inflammation but no suppuration.

4. Dirty or Infected Wounds

Trauma wounds with necrotic tissue.

Visceral perforation.

Has an infected wound.

(1) First disinfect with iodine, alcohol, or purple water, and wipe from the inside to the outside along the edge of the wound. Do not apply iodine or alcohol to the wound. If there is a foreign body in the wound, it should be handled with care. Large and easy to take can be removed; deep and small can't be removed easily, so as not to bring bacteria into the wound or increase bleeding.

Healing type

There are three types of wound healing: primary healing, secondary healing, and tertiary healing.

1. When washing the wound, the patient should try to maintain a relaxed state and distract him;

2. Those who have pain in the wound can take analgesics or spray pain reliever before cleaning the wound;

3. If the wound has pus, use two cotton balls to squeeze it as far as possible;

4. If there is bleeding in the wound, put a little pressure on the bleeding to help stop bleeding;

5. Festering wound has a foul odor, which indicates that there is necrotic tissue, such as rotten tissue. You can first rinse with tap water under high pressure. After cleaning the wound, try to remove the rotten flesh, and then cover it with activated carbon dressing to help absorb the odor;

6. If there is a tunnel or fistula in the wound, it should be stuffed with gauze to help drain the exudate;

7. When the wound is gradually healing, hyperplasia of the outer skin of the skin can be seen. At this time, a lipid hydrogel dressing is applied to prevent the skin from being healed when the dressing is removed.
