puncture wound

wound (wldbomacnd) trauma; an injury, usually restricted to a physical one with disruption of normal continuity of structures.

lacerated wound  one in which the tissues are torn.

open wound  one having a free outward opening.

penetrating wound  one caused by a sharp, usually slender object, which passes through the skin into the underlying tissues.

puncture wound

Etymology: L, punctura + AS, wund

a traumatic injury caused by skin penetration by an object, such as a knife, nail, or slender fragment of metal, wood, glass, or other material. In such an injury to the eye, a lung, or a visceral organ, the object or implement is not removed until the person has been transported to a medical facility. Minor puncture wounds are treated with thorough cleansing. If a puncture wound is allowed to close at the skin before deeper healing has occurred, suppuration often results. A tetanus toxoid immunization is usually given for such wounds.

wound drain

any device by which a channel or open area may be established for the exit of material from a wound or cavity. See also drain, drainage, wound healing (below).

wound healing

the restoration of integrity to injured tissues by replacement of dead tissue with viable tissue. The process starts immediately after an injury and may continue for months or years, and is essentially the same for all types of wounds. Variations in wound healing are the result of differences in location, severity of the wound, and the extent of injury to the tissues. Other factors affecting wound healing are the age, nutritional status and general state of health of the animal and its body reserves and resources for the regeneration of tissue.

In healing by first intention (primary union), restoration of tissue continuity occurs directly, without granulation; in healing by second intention (secondary union), wound repair following tissue loss (as in ulceration or an open wound), is accomplished by closure of the wound with granulation tissue. This tissue is formed by proliferation of fibroblasts and extensive capillary budding at the outer edges and base of the wound cavity. Healing by third intention (delayed primary closure) occurs when a wound is initially too contaminated to close and is closed surgically 4 or 5 days after the injury.

The insertion of drains can facilitate healing by providing an outlet for removing accumulations of serosanguineous fluid and purulent material, and obliterating dead space.
