Is an open wound better for scabs to heal?
This approach is wrong. A scab is a hard crust that forms when the wound exudate and necrotic tissue are dehydrated and air-dried. After the scab is formed, the exudate under the scab cannot be discharged, which is not conducive to wound healing and is prone to re-infection.
The principles of modern surgical wound treatment are dressing, dressing, preventing scab, and promoting wet healing. In other words, it is necessary to provide a moist physiological environment for the cells of the wound to prevent it from forming scabs. Dressing is used to stop bleeding, reduce inflammation, protect the wound, and at the same time drain the wound exudate to promote wound healing.

How to treat a wound at home after an injury?

1. Correct hemostasis;
2, try to brake, bandage the wound;
3. Raise the affected limb to a height above the heart to reduce local congestion;
4, cold compress, can relieve pain, reduce wound congestion and inflammation.
How to stop bleeding properly?
After the injury, if there is local bleeding, use a clean gauze or cotton pad to perform local compression for 3-5 minutes. Then use a bandage for a ring wrap or a figure-8 compression wrap. If there is still active bleeding from the affected area, a tourniquet is needed to block the arterial blood flow.
Special reminder: The tourniquet should not exceed 1 hour. After the bleeding stops, the tourniquet should be lifted, otherwise it is easy to cause distal ischemia and necrosis.
Why go to the hospital for treatment?
The hospital treats wounds in a standardized way, one is to avoid the risk of infection, the other is to make the wound heal better, and at the same time, it can minimize scars and optimize the function of the affected area.
What is the standard configuration of a home first aid kit?
Home first aid kits include: sterile saline, gauze, bandages, medical tape, tourniquets, cotton pads, sterile dressings, iodophors, cotton swabs, and band-aids.
