n.

A wound in which the injured tissues are exposed to the air.

open wound

Etymology: AS, open + wund

a wound that disrupts the integrity of the skin.

---

open

1. said of tissues, cavities and lesions which are normally enclosed when they are exposed to the environment.

2. not pregnant but capable of being pregnant.

---

open case

lesions which carry a heavy load of infection are exposed to the air and represent a potent source of infection for other animals, e.g. an open case of bovine tuberculosis where the cow has extensive pulmonary lesions which are open to the bronchi.

open-chest

usually refers to thoracotomy or other procedure in which there is an opening in the chest wall.

open-heart

surgery in which the heart itself is exposed.

open heels

when the heels in the horse's feet are wide apart.

open joint

the joint capsule and synovial membrane have been punctured and the synovial lining of the joint is exposed to the air.

open pen feedlot

the animals in the lot are without shelter.

open wound

one without apposition of skin edges or left without sutures, usually to allow drainage and healing by granulation.

---

wound

a bodily injury caused by physical means, with disruption of the normal continuity of structures.

avulsive wound

see avulsion.

blowing wound

open pneumothorax.

wound contracture

see contracture.

contused wound

one in which the skin is unbroken.

wound débridement

see débridement.

wound dehiscence

see dehiscence.

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.

wound healing agents

topical agents which stimulate healing; includes preparations containing zinc, trypsin, neomycin, dyes and iodine.

incised wound

one caused by a cutting instrument.

lacerated wound

one in which the tissues are torn.

wound nonhealing

failure to heal despite appropriate treatment being given.

open wound

one that communicates directly with the atmosphere.

penetrating wound

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

perforating wound

a penetrating wound which extends into a viscus or bodily cavity.

pocket wound

chronic, nonhealing wound in which there is granulation tissue but the overlying skin does not adhere. Seen most commonly in the axillae or groin of cats.

puncture wound

penetrating wound.

sucking wound

a penetrating wound of the chest through which air is drawn in and out.

surgical wound

one deliberately produced during a surgical procedure, e.g. the original incision.

tangential wound

an oblique, glancing wound which results in one edge being undercut.

traumatopneic wound

sucking wound.
