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]
An abrasion is a partial thickness wound caused by damage to the skin. [1] It can be superficial involving only the epidermis to deep, involving the deep dermis. Abrasions usually involve minimal bleeding. [ 2 ]
Wound healing refers to a living organism's replacement of destroyed or damaged tissue by newly produced tissue. [1] In undamaged skin, the epidermis (surface, epithelial layer) and dermis (deeper, connective layer) form a protective barrier against the external environment. When the barrier is broken, a regulated sequence of biochemical events ...
A stab wound from a knife or other sharp object, or a bullet wound, are examples of this type of injury. Medical professionals usually refer to this type of wound as penetrating trauma. Abrasion: A scraping or scratching. Generally quite superficial, and affecting only the surface layers of the epidermis. [7]
Initial assessment of a gunshot wound to the neck involves non-probing inspection of whether the injury is a penetrating neck injury (PNI), classified by violation of the platysma muscle. [29] If the platysma is intact, the wound is considered superficial and only requires local wound care.
Burns that affect only the superficial skin layers are known as superficial or first-degree burns. [2] [11] They appear red without blisters, and pain typically lasts around three days. [2] [11] When the injury extends into some of the underlying skin layer, it is a partial-thickness or second-degree burn. [2]
A superficial gunshot wound to the armpit. As a missile passes through tissue, it decelerates, dissipating and transferring kinetic energy to the tissues. [1] The velocity of the projectile is a more important factor than its mass in determining how much damage is done; [1] kinetic energy increases with the square of the velocity.
The dermis contains two vascular networks that run parallel to the skin surface—one superficial and one deep plexus—which are connected by vertical communicating vessels. [8] [11] The function of blood vessels within the dermis is fourfold: to supply nutrition, to regulate temperature, to modulate inflammation, and to participate in wound ...
