Types of Wounds
A wound is an injury or damage to live tissue caused by a variety of factors.
WOUND
A wound is an injury or damage to live tissue caused by a variety of factors. Different agents induce different sorts of wounds with differing degrees of severity. Some wounds are mild, while others might be serious enough to render an organ, tissue, or cell ineffective.
Cause of Wounds
- Mechanical agents: Mechanical forces acting on a tissue can result in a wound. A Contusion occurs when a mechanical force works on a tissue and causes harm with the wound staying closed a Laceration occurs when a mechanical force acts on a tissue and causes an open wound.
- Chemical agents: These are corrosive liquids or gases, such as concentrated acids or powerful alkalis (bases), as well as poisons from venomous snake or insect bites that can cause tissue wounds..
- Radiant agents: X-rays, atomic energy, heat, high-voltage electricity, and extreme cold are all examples of radiation. Tissue necrosis can be caused by any of these factors.
- Biological agents: These organisms do not produce wounds directly; instead, they infiltrate an existing wound, causing widespread tissue necrosis and expanding it. Toxins, which assist infections breakdown tissue and can cause hypersensitive reactions, are used by pathogens.
Classifications of Wounds based on their nature
Closed Wound: These are wounds that occur without the loss of the wound’s superficial covering. The wound develops beneath the skin’s surface and has no effect on the skin. Contusion is an example of this sort of wound. Infection of these wounds is uncommon, and if it is not severe, it may heal without therapy.
Open Wound: These are wounds in which the tissue’s superficial surface layer, such as skin, has been lost. In open wounds, microbial invasion is the most common concern. The most prevalent causes of open wounds include falls, incidents with sharp objects, and car accidents. In the event of a catastrophic accident, you should seek medical attention right once. This is especially true if the bleeding is extensive or lasts longer than 20 minutes.
Different types of open wounds
- Laceration
- Abrasion
- Avulsion
- Perforations or Penetrating wounds
- Punctured wound
Laceration: Lacerations are deep cuts or tears in the skin. Lacerations are frequently caused by accidents involving blades, tools, and machinery. Deep lacerations can result in quick and significant bleeding.
Abrasion: When human skin rubs or scrapes against a rough or hard surface, then get an abrasion. Abrasions include things like road rash. Although there is usually little bleeding, the area must be cleansed and cleaned to prevent infection.
Avulsion: An avulsion is a tearing away of the skin and the tissue beneath it, which can be partial or complete. Avulsions are most common in violent accidents including car crashes, explosions, and gunfire. They bleed profusely and quickly.
Penetrating wound: These result from trauma that breaks through the full thickness of skin reaching down to the underlying tissue and organs, and includes Stab wounds (trauma from sharp objects, such as knives), Skin cuts, Surgical wounds
Punctured wound: A puncture is a small hole made by a long, sharp item like a nail or a needle. A gunshot can sometimes produce a puncture wound. Punctures may not bleed much, but they can cause internal organ damage if they are deep enough. Visit your doctor for a tetanus injection to avoid infection if you have even a little puncture hole.
