  2. Skin repair - Wikipedia

    en.wikipedia.org/wiki/Skin_repair

    In a major injury, if epithelial cell migration and tissue contraction cannot cover the wound, suturing the edges of the injured skin together, or even replacement of lost skin with skin grafts, may be required to restore the skin. As epithelial cells continue to migrate around the scab, the dermis is repaired by the activity of stem cells.

  3. Wound healing - Wikipedia

    en.wikipedia.org/wiki/Wound_healing

    Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.

  4. Wound healing assay - Wikipedia

    en.wikipedia.org/wiki/Wound_healing_assay

    One limitation of this assay is that there could be inconsistencies with the depth and size of the scratch. When the scratch is done manually, it's susceptible to 'ragged' edge boundaries, which make analyzing data more difficult. [6] Also, the damage could physically damage the cells adjacent to the wound and create inaccurate wound size areas ...

  5. Wound assessment - Wikipedia

    en.wikipedia.org/wiki/Wound_assessment

    Wound bed, wound edge and periwound skin should be examined before the initial treatment plan is devised. It should also be re-assessed at each visit or each dressing change. For wound bed, the following parameters are assessed: Tissue type; presence and percentage of non-viable tissue covering the wound bed; Level of exudate; Presence of infection

  6. Emergency bleeding control - Wikipedia

    en.wikipedia.org/wiki/Emergency_bleeding_control

    The most common descriptors of wounds are these: Incision: Straight edges to the wound margins, as if sliced with a knife. These can vary in size, and may be caused by a variety of objects, including a scalpel, a knife, any piece of straight, sharp metal, or a piece of glass. Tissue is rarely missing from the wound site, and the margins of the ...

  7. Wound - Wikipedia

    en.wikipedia.org/wiki/Wound

    A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. [1] [2] Wounds can either be the sudden result of direct trauma (mechanical, thermal, chemical), or can develop slowly over time due to underlying disease processes such as diabetes mellitus, venous/arterial insufficiency, or immunologic disease. [3]

  8. Granulation tissue - Wikipedia

    en.wikipedia.org/wiki/Granulation_tissue

    Granulation tissue is new connective tissue and microscopic blood vessels that form on the surfaces of a wound during the healing process. [1] Granulation tissue typically grows from the base of a wound and is able to fill wounds of almost any size. Examples of granulation tissue can be seen in pyogenic granulomas and pulp polyps.

  9. International Red Cross Wound Classification System

    en.wikipedia.org/wiki/International_Red_Cross...

    The International Red Cross wound classification system is a system whereby certain features of a wound are scored: the size of the skin wound(s); whether there is a cavity, fracture or vital structure injured; the presence or absence of metallic foreign bodies. A numerical value is given to each feature (E, X, C, F, V, and M).
