Operation steps of debridement:

1. judging the injury: all kinds of trauma patients are injured by violence to varying degrees, so patients should be carefully examined before operation.

2. Anesthesia and posture.

3. Clean the skin: first cover the wound with sterile gauze and scrub the dirt on the skin outside the wound with alcohol.

4. Cleaning the wound: remove the gauze covering the wound, alternately clean the wound with 3% hydrogen peroxide, 1: 1000 benzalkonium bromide and sterile physiological saline for three times, and take out obvious foreign bodies and blood clots with sterile tweezers.

5. Clean up the skin: the operator washes his hands regularly, disinfects the skin around the wound with iodophor, spreads sterile towels, and wears surgical gowns and sterile gloves in turn.

6. Clean the tissue: according to the anatomical level, gradually clean the wound from shallow to deep.

7. Clean-up of special organizations:

(1) vascular management.

(2) Neurotherapy.

(3) Treatment of muscles, fascia and tendons.

(4) Treatment of joint capsule injury.

(5) Handling of decapitation.

8. Re-cleaning: After the above treatment steps, the tissue debris generated during debridement should be washed with normal saline.

9. Repair of the organization:

(1) vascular repair.

(2) nerve repair.

(3) tendon repair.

(4) Joint capsule repair.

(5) Reduction and fixation of fracture.

10. Close the wound: after the wound is completely stopped bleeding and repaired, it can be closed layer by layer in one stage, and attention should be paid to the combination of tissue layers during suture.

1 1. End of operation: After the operation, the cleaning materials should be counted and put in the designated place, and the used dressings and cleaned paper towels should be put in the designated place according to the regulations.

Explanation:

Debridement is a surgical method to remove foreign bodies from an open wound, remove necrotic, inactivated or seriously polluted tissues, suture the wound, minimize pollution, and even turn it into a clean wound to achieve primary healing, which is conducive to the recovery of the function and shape of the injured part.

Brief introduction of debridement:

Open wounds are generally divided into three categories: cleaning, pollution and infection. Strictly speaking, cleaning wounds is rare; Accidental wounds are inevitably polluted to varying degrees; If the pollution is serious, the bacteria are rich and toxic, it can become an infected wound after 8 hours. The local blood supply of the head and face wound is good, and the wound can still be debrided according to the polluted wound 12 hours after the injury.

Debridement is a basic surgical operation. The quality of initial wound treatment plays a decisive role in wound healing and the recovery of injured tissue function and morphology, which should be paid attention to.
