All human beings are at risk for sustaining or developing wounds, but the risk is higher in children, elderly people, alcoholics, those with addiction to narcotics, or people with mental illness or disability. Scarring: Regenerated cells have different characteristics and fibrous tissue that can heal the wound, but may leave a scar behind. Open wounds are extremely painful to victims and intimidating to those who must treat them. Wound maturation starts when collagen has been adequately deposited to wound. Infections: Wound infection presents with pus drainage, foul odor, fever, dull throbbing pain, mild swelling and heat at wound site. Laceration. Avulsion. Wound types. They can be Arterial, venous, or mixed. Different wounds may require different first aid treatments however the overall aim is to control bleeding and minimise the risk of infection. If you see a doctor for wound care, he or she will want to know about any existing health conditions and your diet, to determine whether there is a connection in what’s causing your wound not to heal. Loss of function: Many wounds can be disabling and life threatening if a major organ, blood vessel or nerve was damaged. Wound origin can be either internal or external. When a swollen leg is injured the swelling can interfere with normal healing and lead to a venous leg ulcer. There are four types of open wounds, which are classified depending on their cause. Lacerated wound: a wound where the tissues are torn, usually by blunt force leaving ragged edges. Often times these open wounds will form a scab as a natural bandage. Wounds 1. Types of Wounds. These chronic wounds are almost always associated with underlying chronic diseases that affect either the blood supply or how the cells function at the wound site. External wounds are usually caused by penetrating objects or non-penetrating trauma, and other miscellaneous causes as follows: The signs and symptoms depend on the wound site, depth and causative agent. Lacerations – irregular tear-like wounds caused by some blunt trauma. Clean the wound by rinsing with water, and then flushing with a sterile solution to rid the affected area of bacteria and debris. Abrasion. These are: Also known as bed sores, pressure sores or decubitus ulcers, these wounds are caused by pressure and/or shearing force on the skin. Non-penetrating wounds: These are usually the result of blunt trauma or friction with other surfaces; the wound does not break through the skin, and may include: Abrasions (scraping of the outer skin layer), Contusions (swollen bruises due to accumulation of blood and dead cells under skin), Concussions (damage to the underlying organs and tissue on head with no significant external wound). Incised: a cut with clean, straight edges which may bleed frequently but generally heals quite quickly. a physical injury where the skin or mucous membrane is torn Puncture wounds: These types of wounds are classified as open wounds and are typically the result of a foreign object accidentally puncturing the skin. Punctured Wounds. Arterial insufficiency ulcers, Ischemic ulcers, Ischemic wounds are common wounds located on the lateral surface of the ankle or side of the foot caused by poor perfusion to the lower extremities. Created by. Wounds are often categorized into four main classes based on the type of injury. Mixed ulcers are due to a combination of venous and arterial disease. Once wound occurs body tries to repair the defect and the process of wound healing is a summation of a number of processes which follow injury including coagulation, inflammation, matrix synthesis and deposition, angiogenesis, fibroplasia, … This table summarises the different types of wounds, their typical characteristics and possible … They may heal at a much slower rate, heal only partially or reoccur after partial or complete healing. However there are several types of wounds that account for the majority of chronic wounds. … WOUNDS Dr Phillipo L. Chalya MD, M.Med(Surg) Senior Lecturer – Department of Surgery CUHAS 2. Incision.

First, second and third degree burns caused by any source- heat, chemicals, or electricity that damages the body’s tissues. A wound is an injury to living tissue caused by a cut, blow, or other impacts, typically one in which the skin is cut or broken. These are: Pressure Injuries. Chronic wounds are challenging and costly to treat. Abrasion. When you consider the manner in which the skin or tissue is broken, there are six general kinds of wounds: abrasions, incisions, lacerations, punctures, avulsions, and amputations. Any acute wound (eg skin tear, surgical incision) can become chronic if the person has risk factors that impact on wound healing. Tends not to be very deep but can often contain many foreign bodies such as dirt (i.e. Either way, while the wound is still fresh or healing, the affected limb or area will lose its functionality until all lost or damaged tissue is repaired. Surgical Wounds. TYPES OF WOUNDS. Penetrating wounds: These result from trauma that breaks through the full thickness of skin; reaching down to the underlying tissue and organs, and includes: Stab wounds (trauma from sharp objects, such as knives), Gunshot wounds (wounds resulting from firearms), Thermal wounds: Extreme temperatures, either hot or cold, can result in thermal injuries (like, Chemical wounds: These result from contact with or inhalation of chemical materials that cause skin or lung damage. Be it a minor cut or perhaps a deep incision; it is imperative that you take good care to avoid further complications. Internal wounds result from impaired immune and nervous system functions and/or decreased supply of blood, oxygen or nutrients to that area; such as in cases of chronic medical illness (diabetes, atherosclerosis, deep vein thrombosis). –6 stages or categories: •Stage I •Stage II •Stage III •Stage IV •Unstageable •Suspected deep tissue injury (sDTI) •Base staging on the type of tissue visualized or palpated. There are three main types: Serious ulcers and infections, if left untreated or even with treatment, may lead to minor (foot or toe) or major (below or above the knee) lower leg amputation.
