VARIOUS INJURIES - VARIOUS SPECIFICATION FOR GOING ON THE SI�??
Depending on the size and form of the wound, we distinguish:
♦ Wound healing by shortening
♦ Wound healing by granulation
♦ Wound healing under scab
♦ Healing of atypical wounds - frostbite, burns, decubitus ulcers
Dig. Cuteness and skin layers:
A - epidermis; B - dermis; C - subcutaneous tissue They can be damaged and bleed:
1. Cutaneous and vascular papillomas
2. The hook of the hair shaft
3. Sebaceous gland
4. Hair
5. Blood capillaries
6. Fat cells
7. Arteries and veins of the skin
8. Sweat glands
9. Hair follicle
10. Endings of nerve receptors
Healing of cuts by rychłozrost (Latin per primam intentionem)
A small wound and cut is usually healed by getting short. This is because the edges of the wound stick together. Relatively quickly, the continuity of the skin is reproduced, a linear scar is created. This is the most beneficial way to heal wounds. However, the wound is not always healed in this way.
Healing of cut and surgical wounds by rapidly growing
In this way, they also heal quite deeply, or extensive cut wounds and others with regular edges, in which there was no significant loss of tissue. The rule is the use of seams that bring the edges of the wound closer together. The adhesion occurs quickly (about 8 days, maximum 6-8 weeks), because the wound edges are directly connected, mainly by the migration of epidermal cells from the hair follicles and the skin, and to a lesser extent by the production of connective tissue.
Healing by granulation (Latin per secundam intentionem)
This type of wound healing occurs when, for example, a large skin loss occurs due to injury and wound "wow", wound infection has occurred, there is elastic skin tone on both sides, etc. In a word, the wound was not initially closed. If such a wound is thoroughly cleaned and disinfected, then the granulation tissue from the growing blood vessels will start to grow on its bottom. This granule is a substrate for the regeneration of superficial layers of the skin and the epidermis, which grows from the edges of the wound. Such healing of the open wound requires careful care and frequent dressing changes. Although sometimes severely contaminated wounds, or to a large extent exposed to the development of infection, are deliberately left open to allow the natural immune mechanisms of the body to work. The scar remaining after the wound healing by granulation is usually large and visible.
Healing under the scab (Latin: sub crustam)
The healing of wounds under the scab has the locality when the tissue loss is filled with a blood clot that will dry out. The resulting scab becomes a natural dressing. The granulation of new layers of the skin, including epidermal regeneration, starts below it
THE TEMPEST OF GOING TO GO? WOUNDS
Wound healing time is individual and depends on
- the type of injury, shape and size of the wound
- amount of damaged tissues
- the degree of contamination of the wound and the quality of its decontamination
- body injuries
The rate and correct healing of wounds are affected by:
• Degree of tissue damage
• The presence of a hematoma within the wound (associated with a higher rate of infection)
• Blood supply
• Temperature
• Presence of infection
• Wound closure technique and type of seams
General factors conditioning the rate of wound healing:
• Nutrition of the patient and the condition of the immune system
• The existence of a chronic disease that hampers healing (diabetes, hypertension, infection, etc.)
• The use of healing therapies - chemotherapy, treatment with steroids, the use of anticoagulants, etc..
Healing of atypical wounds - frostbite, burns, decubitus ulcers
