Caused by a sharp instrument, is open, deep or shallow

Surgical wounds with entry to body tracts but no evidence of infection

a wound that is the result of a planned surgical or medical intervention

surgery, intravenous therapy, and lumbar puncture. The wound edges are clean, and bleeding is usually controlled. Because the wound was made under sterile conditions with sterile supplies and skin preparation, the risk for infection is decreased, and healing is facilitated.

Caused by a blow from a blunt object, is a closed wound, but may have ecchymosis (bruising) from damaged blood vessels

Contaminated wounds, show evidence of inflammation

wounds occur from unexpected trauma, such as from accidents, forcible injury (such as a stabbing or a gunshot), and burns.

Because the wounds occur in an unsterile environment, contamination is likely. Wound edges are usually jagged, multiple traumas are common, and bleeding is uncontrolled. These factors create a high risk for infection and a longer healing time.

Surface scrape unintentional like scraped knee or intentional like plaque removal, open wound

Seen immediately following injury.
Control bleeding then prevent infection

Occurs from intentional or unintentional trauma. The skin surface is broken, providing a portal of entry for microorganisms.

Bleeding, tissue damage, and increased risk for infection and delayed healing may accompany open wounds.

Penetration of the skin and often underlying tissue by a sharp instrument. intentional like a biopsy, unintentional like a nail, open wound

Non-blanceable redness of intact skin, ulcer starting, area may be painful and have a different temp than other skin

blow, force, or strain caused by trauma such as a fall, an assault, or a motor vehicle crash.

The skin surface is not broken, but soft tissue is damaged, and internal injury and hemorrhage may occur.

Tissue torn apart often accidental, described as an open wound often with jagged edges

Partial thickness skin loss involving dermis, shallow open ulcer without slough, may present with a blister that is fluid filled or a shiny dry ulcer without slough

surgical incisions, usually heal within days to weeks. The wound edges are well approximated (edges meet to close skin surface) and the risk of infection is lessened.
