Pressure ulcers, also known as pressure sores, bed sores or pressure injuries, are localised damage to the skin and/or underlying tissue that usually occur over a bony prominence as a result of usually long-term pressure, or pressure in combination with shear or friction. The most common sites are the skin overlying the sacrum, coccyx, heels, and hips, though other sites can be affected, such as the elbows, knees, ankles, back of shoulders, or the back of the cranium.

Contents

Pressure ulcers occur due to pressure applied to soft tissue resulting in completely or partially obstructed blood flow to the soft tissue. Shear is also a cause, as it can pull on blood vessels that feed the skin. Pressure ulcers most commonly develop in individuals who are not moving about, such as those who are on chronic bedrest or consistently use a wheelchair. It is widely believed that other factors can influence the tolerance of skin for pressure and shear, thereby increasing the risk of pressure ulcer development. These factors are protein-calorie malnutrition, microclimate (skin wetness caused by sweating or incontinence), diseases that reduce blood flow to the skin, such as arteriosclerosis, or diseases that reduce the sensation in the skin, such as paralysis or neuropathy. The healing of pressure ulcers may be slowed by the age of the person, medical conditions (such as arteriosclerosis, diabetes or infection), smoking or medications such as anti-inflammatory drugs.

Although often prevented and treatable if detected early, pressure ulcers can be very difficult to prevent in critically ill people, frail elders, and individuals with impaired mobility such as wheelchair users (especially where spinal injury is involved). Primary prevention is to redistribute pressure by regularly turning the person. The benefit of turning to avoid further sores is well documented since at least the 19th century. [1] In addition to turning and re-positioning the person in the bed or wheelchair, eating a balanced diet with adequate protein [2] and keeping the skin free from exposure to urine and stool is important. [3]

The rate of pressure ulcers in hospital settings is high; the prevalence in European hospitals ranges from 8.3% to 23%, and the prevalence was 26% in Canadian healthcare settings from 1990 to 2003. [4] In 2013, there were 29,000 documented deaths from pressure ulcers globally, up from 14,000 deaths in 1990. [5]

The United States has tracked rates of pressure injury since the early 2000s. Whittington and Briones reported nationwide rates of pressure injuries in hospitals of 6% to 8%. [6] By the early 2010s, Lyder and colleagues had research the rate of pressure injury to drop to about 4.5% across the Medicare population, following the introduction of the International Guideline for pressure injury prevention. [7] Padula and colleagues have witnessed a +29% uptick in pressure injury rates in recent years associated with the rollout of penalizing Medicare policies. [8]

Presentation

Complications

Pressure ulcers can trigger other ailments, cause considerable suffering, and can be expensive to treat. Some complications include autonomic dysreflexia, bladder distension, bone infection, pyarthrosis, sepsis, amyloidosis, anemia, urethral fistula, gangrene and very rarely malignant transformation (Marjolin's ulcer - secondary carcinomas in chronic wounds). Sores may recur if those with pressure ulcers do not follow recommended treatment or may instead develop seromas, hematomas, infections, or wound dehiscence. Paralyzed individuals are the most likely to have pressure sores recur. In some cases, complications from pressure sores can be life-threatening. The most common causes of fatality stem from kidney failure and amyloidosis. Pressure ulcers are also painful, with individuals of all ages and all stages of pressure ulcers reporting pain.[ citation needed ]

Cause

There are four mechanisms that contribute to pressure ulcer development: [9]

  1. External (interface) pressure applied over an area of the body, especially over the bony prominences can result in obstruction of the blood capillaries, which deprives tissues of oxygen and nutrients, causing ischemia (deficiency of blood in a particular area), hypoxia (inadequate amount of oxygen available to the cells), edema, inflammation, and, finally, necrosis and ulcer formation. Ulcers due to external pressure occur over the sacrum and coccyx, followed by the trochanter and the calcaneus (heel).
  2. Friction is damaging to the superficial blood vessels directly under the skin. It occurs when two surfaces rub against each other. The skin over the elbows can be injured due to friction. The back can also be injured when patients are pulled or slid over bed sheets while being moved up in bed or transferred onto a stretcher.
  3. Shearing is a separation of the skin from underlying tissues. When a patient is partially sitting up in bed, skin may stick to the sheet, making the skin susceptible to shearing in case underlying tissues move downward with the body toward the foot of the bed. This may also be possible on a patient who slides down while sitting in a chair.
  4. Moisture is also a common pressure ulcer culprit. Sweat, urine, feces, or excessive wound drainage can further exacerbate the damage done by pressure, friction, and shear. It can contribute to maceration of surrounding skin thus potentially expanding the deleterious effects of pressure ulcers.

Risk factors

There are over 100 risk factors for pressure ulcers. [10] Factors that may place a patient at risk include immobility, diabetes mellitus, peripheral vascular disease, malnutrition, cerebral vascular accident and hypotension. [10] [11] Other factors are age of 70 years and older, current smoking history, dry skin, low body mass index, urinary and fecal incontinence, physical restraints, malignancy, vasopressin prescription, and history of prior pressure injury development. [12]

Pathophysiology

Pressure ulcers may be caused by inadequate blood supply and resulting reperfusion injury when blood re-enters tissue. A simple example of a mild pressure sore may be experienced by healthy individuals while sitting in the same position for extended periods of time: the dull ache experienced is indicative of impeded blood flow to affected areas. Within 2 hours, this shortage of blood supply, called ischemia, may lead to tissue damage and cell death. The sore will initially start as a red, painful area. The other process of pressure ulcer development is seen when pressure is high enough to damage the cell membrane of muscle cells. The muscle cells die as a result and skin fed through blood vessels coming through the muscle die. This is the deep tissue injury form of pressure ulcers and begins as purple intact skin. [13]

According to Centers for Medicare and Medicaid Services, pressure ulcers are one of the eight preventable iatrogenic illnesses. If a pressure ulcer is acquired in the hospital, the hospital will no longer receive reimbursement for the person's care. Hospitals spend about $27 billion annually for treatment of pressure injuries. [14] Whereas, the cost of pressure injury prevention is cost-effective, if not cost-saving, and would cost less than half the amount of resources to prevent compared to treat in health systems. [15]

Common pressure sore sites include the skin over the ischial tuberosity, the sacrum, the heels of the feet, over the heads of the long bones of the foot, buttocks, over the shoulder, and over the back of the head. [16]

Biofilm

Biofilm is one of the most common reasons for delayed healing in pressure ulcers. Biofilm occurs rapidly in wounds and stalls healing by keeping the wound inflamed. Frequent debridement and antimicrobial dressings are needed to control the biofilm. Infection prevents the healing of pressure ulcers. Signs of pressure ulcer infection include slow or delayed healing and pale granulation tissue. Signs and symptoms of systemic infection include fever, pain, redness, swelling, warmth of the area, and purulent discharge. Additionally, infected wounds may have a gangrenous smell, be discolored, and may eventually produce more pus.[ citation needed ]

In order to eliminate this problem, it is imperative to apply antiseptics at once. Hydrogen peroxide (a near-universal toxin) is not recommended for this task as it increases inflammation and impedes healing. [17] Dressings with cadexomer iodine, silver, or honey have been shown to penetrate bacterial biofilms. Systemic antibiotics are not recommended in treating local infection in a pressure ulcer, as it can lead to bacterial resistance. They are only recommended if there is evidence of advancing cellulitis, bony infection, or bacteria in the blood. [18]

Diagnosis

Classification

Stages I to IV of a pressure ulcer

The definitions of the pressure ulcer stages are revised periodically by the National Pressure Injury Advisory Panel (NPIAP) [19] in the United States and the European Pressure Ulcer Advisory Panel (EPUAP) in Europe. [20] Different classification systems are used around the world, depending upon the health system, the health discipline and the purpose for the classifying (e.g. health care versus, prevalence studies versus funding. [21] Briefly, they are as follows: [22] [23]

The term medical device related pressure ulcer refers to a cause rather than a classification. Pressure ulcers from a medical device are classified according to the same classification system being used for pressure ulcers arising from other causes, but the cause is usually noted.

Ischemic fasciitis

Ischemic fasciitis (IF) is a benign tumor in the class of fibroblastic and myofibroblastic tumors [32] that, like pressure ulcers, may develop in elderly, bed-ridden individuals. [33] These tumors commonly form in the subcutaneous tissues (i.e. lower most tissue layer of the skin) that overlie bony protuberances such as those in or around the hip, shoulder, greater trochanter of the femur, iliac crest, lumbar region, or scapular region. [34] IF tumors differ from pressure ulcers in that they typically do not have extensive ulcerations of the skin and on histopathological microscopic analysis lack evidence of acute inflammation as determined by the presence of various types of white blood cells. [35] These tumors are commonly treated by surgical removal. [36]

Prevention

There are various approaches that are used widely for preventing pressure ulcers. [37] Suggested approaches include modifications to bedding and mattresses, different support systems for taking pressure off of affected areas, airing of surfaces of the body, skin care, nutrition, and organizational modifications (for example, changing the care routines in hospitals or homes where people require extended bedrest). [37] [38] Overall, unbiased clinical studies to determine the effectiveness of these types of interventions and to determine the most effective intervention are needed in order to best prevent pressure ulcers. [37] [39] [40] [41] [42]

Clinical guidelines for preventing pressure ulcers

Numerous evidence-based and expert consensus-based clinical guidelines have been to developed to help guide medical professionals internationally [21] and in specific countries including the UK. [43] [44] [45] The Standardized Pressure Injury Prevention Protocol (SPIPP) Checklist is a derivative of the International Guideline that was designed to facilitate consistent implementation of pressure injury prevention. [46] In 2022, United States Congress passed legislation updating the Military Construction and Veterans Affairs and Related Agencies Appropriations Act, 2015 (H.R. 4355) to establish the SPIPP Checklist as law that United States Department of Veterans Affairs (VA) facilities should adhere to in order to keep patients safe from harm.

Risk assessment

Before turning and repositioning a person, a risk assessment tool is suggested to determine what is the best approach for preventing pressure ulcers in that person. Some of the most common risk assessment tools are the Braden Scale, Norton, or Waterlow tools. The type of risk assessment tool that is used, will depend on which hospital the patient is admitted to and the location. After the risk assessment tool is used, a plan will be developed for the patient individually to prevent Hospital- Acquired Pressure Injuries. This plan will consist of different turning and repositioning strategies. These risk assessment tools provide the nursing staff with a baseline for each patient regarding their individual risk for acquiring a pressure injury. Factors that contribute to these risk assessment tools are moisture, activity, and mobility. These factors are considered and scored using the scale being used, whether it be the Braden, Norton, or Waterlow scale. The numbers are then added up and based on that final number, a score will be given and appropriate measures will be taken to ensure that the patient is being properly repositioned. Unfortunately, this is not always completed in hospitals like it should be. [47]

Efforts in the United States and South Korea have sought to automate risk assessment and classification by training machine learning models on electronic health records. [48] [49] [50]

Redistribution of pressure

An important aspect of care for most people at risk for pressure ulcers and those with bedsores is the redistribution of pressure so that no pressure is applied to the pressure ulcer. [51] In the 1940s Ludwig Guttmann introduced a program of turning paraplegics every two hours thus allowing bedsores to heal. Previously such individuals had a two-year life-expectancy, normally succumbing to blood and skin infections. Guttmann had learned the technique from the work of Boston physician Donald Munro. [52] There is lack of evidence on prevention of pressure ulcer whether the patient is put in 30 degrees position or at the standard 90 degrees position. [53]

Nursing homes and hospitals usually set programs in place to avoid the development of pressure ulcers in those who are bedridden, such as using a routine time frame for turning and repositioning to reduce pressure. The frequency of turning and repositioning depends on the person's level of risk.[ citation needed ]

Various interventions have been developed to redistribute pressure including the use of different bed mattresses, support surfaces, and the use of static chairs.

Support surfaces

The use of different types of mattresses including high density foam, surfaces with reactive fibers or gels in them, and surfaces that incorporate reactive water are sometimes suggested to redistribute pressure. The evidence supporting these interventions and whether they prevent new ulcers, increase the comfort level, or have other positive or more negative adverse effects is weak. [54] [55] Many support surfaces redistribute pressure by immersing and/or enveloping the body into the surface. Some support surfaces, including antidecubitus mattresses and cushions, contain multiple air chambers that are alternately pumped. [56] [57] Methods to standardize the products and evaluate the efficacy of these products have only been developed in recent years through the work of the S3I within NPUAP. [58]

There is some evidence that the use of foam mattresses is not as effective as support approaches that include alternating pressure air surfaces or reactive surfaces. [59] [60] It is not clear if interventions that include a reactive air surface are more effective than reactive surfaces that include water or gel or other substrates. [61] [62] In addition, the effectiveness of sheepskin overlays on top of mattresses is not clear. [37]

Static chairs (as opposed to wheelchairs) have also been suggested for pressure redistribution. [63] Static chairs can include: standard hospital chairs; chairs with no cushions or manual/dynamic function; and chairs with integrated pressure redistributing surfaces and recline, rise or tilt functions. More research is needed to establish how effective pressure redistributing static chairs are for preventing pressure ulcers. [63]

For individuals with limited mobility, pressure shifting on a regular basis and using a wheelchair cushion featuring pressure relief components can help prevent pressure wounds. [64]

Nutrition

The benefits of nutritional interventions with various compositions for pressure ulcer prevention are uncertain. [65]

Organisational changes

There is some suggestion that organisational changes may reduce incidence of pressure ulcers, with healthcare professionals central to the prevention of pressure ulcers in both hospital [66] and community settings. [67] It is not clear from studies on the effectiveness of these approaches as to the best organisational change that would benefit those at risk of pressure ulcers including organisation of health services, [38] risk assessment tools, [68] wound care teams, [69] and education. [70] [71] This is largely due to the lack of high-quality research in these areas.

Wound care and dressings

Caring for wounds and ulcers that have been started and the use of creams are also considerations in preventing worsening to ulcers and new primary ulcers. Creams containing fatty acids may be more effective in reducing incidence of pressure ulcers compared to creams without fatty acids. [72] Silicone dressings may also reduce pressure ulcer incidence. [72] There is no evidence that massage reduces pressure ulcer incidence. [73] Controlling the heat and moisture levels of the skin surface, known as skin microclimate management, may also plays a role in the prevention and control of pressure ulcers. [74] Skin care is also important because damaged skin does not tolerate pressure. However, skin that is damaged by exposure to urine or stool is not considered a pressure ulcer. These skin wounds should be classified as Incontinence Associated Dermatitis.[ citation needed ]

Treatment

Recommendations to treat pressure ulcers include the use of bed rest, pressure redistributing support surfaces, nutritional support, repositioning, wound care (e.g. debridement, wound dressings) and biophysical agents (e.g. electrical stimulation). [45] Reliable scientific evidence to support the use of many of these interventions, though, is lacking. More research is needed to assess how to best support the treatment of pressure ulcers, for example by repositioning. [39] [75] [41] [42]

Debridement

Necrotic tissue should be removed in most pressure ulcers. The heel is an exception in many cases when the limb has an inadequate blood supply. Necrotic tissue is an ideal area for bacterial growth, which has the ability to greatly compromise wound healing. There are five ways to remove necrotic tissue.

  1. Autolytic debridement is the use of moist dressings to promote autolysis with the body's own enzymes and white blood cells. It is a slow process, but mostly painless, and is most effective in individuals with a properly functioning immune system.
  2. Biological debridement, or maggot debridement therapy, is the use of medical maggots to feed on necrotic tissue and therefore clean the wound of excess bacteria. Although this fell out of favor for many years, in January 2004, the FDA approved maggots as a live medical device. [76]
  3. Chemical debridement, or enzymatic debridement, is the use of prescribed enzymes that promote the removal of necrotic tissue.
  4. Mechanical debridement, is the use of debriding dressings, whirlpool or ultrasound for slough in a stable wound.
  5. Surgical debridement, or sharp debridement, is the fastest method, as it allows a surgeon to quickly remove dead tissue.

Dressings

It is not clear if one topical agent or dressing is better than another for treating pressure ulcers. [77] There is some evidence to suggest that protease-modulating dressings, foam dressings or collagenase ointment may be better at healing than gauze. [77] The wound dressing should be selected based on the wound and condition of the surrounding skin. There are some studies that indicate that antimicrobial products that stimulate the epithelization may improve the wound healing. [78] However, there is no international consensus on the selection of the dressings for pressure ulcers. [79] Evidence supporting the use of alginate dressings, [80] foam dressings, [81] and hydrogel dressings. [82] and the benefits of these dressings over other treatments is unclear.

Some guidelines for dressing are: [83]

ConditionCover dressing
None to moderate exudates Gauze with tape or composite
Moderate to heavy exudates Foam dressing with tape or composite
Frequent soiling Hydrocolloid dressing, film or composite
Fragile skinStretch gauze or stretch net

Other treatments

Other treatments include anabolic steroids, [84] medical grade honey, [85] negative pressure wound therapy, [86] phototherapy, [87] pressure relieving devices, [88] reconstructive surgery, [89] support surfaces, [90] ultrasound [91] and topical phenytoin. [92] There is little or no evidence to support or refute the benefits of most of these treatments compared to each other and placebo. It is not clear if electrical stimulation is an effective treatment for pressure ulcers. [93] In addition, the benefit of using systemic or topical antibiotics in the management of pressure ulcer is still unclear. [94] The benefit of using systemic or topical antibiotics in the management of pressure ulcer is still unclear. [94] When selecting treatments, consideration should be given to patients' quality of life as well as the interventions' ease of use, reliability, and cost. The benefits of nutritional interventions with various compositions for pressure ulcer treatment are uncertain. [95]

Epidemiology

Each year, more than 2.5 million people in the United States develop pressure ulcers. [96] In acute care settings in the United States, the incidence of bedsores is 0.4% to 38%; within long-term care it is 2.2% to 23.9%, and in home care, it is 0% to 17%. Similarly, there is wide variation in prevalence: 10% to 18% in acute care, 2.3% to 28% in long-term care, and 0% to 29% in home care. There is a much higher rate of bedsores in intensive care units because of immunocompromised individuals, with 8% to 40% of those in the ICU developing bedsores. [97] However, pressure ulcer prevalence is highly dependent on the methodology used to collect the data. Using the European Pressure Ulcer Advisory Panel (EPUAP) methodology there are similar figures for pressure ulcers in acutely sick people in the hospital. There are differences across countries, but using this methodology, pressure ulcer prevalence in Europe was consistently high, from 8.3% (Italy) to 22.9% (Sweden). [98] A recent study in Jordan also showed a figure in this range. [99] Some research shows differences in pressure-ulcer detection among white and black residents in nursing homes. [100]

Otitis media is a group of inflammatory diseases of the middle ear. One of the two main types is acute otitis media (AOM), an infection of rapid onset that usually presents with ear pain. In young children this may result in pulling at the ear, increased crying, and poor sleep. Decreased eating and a fever may also be present. The other main type is otitis media with effusion (OME), typically not associated with symptoms, although occasionally a feeling of fullness is described; it is defined as the presence of non-infectious fluid in the middle ear which may persist for weeks or months often after an episode of acute otitis media. Chronic suppurative otitis media (CSOM) is middle ear inflammation that results in a perforated tympanic membrane with discharge from the ear for more than six weeks. It may be a complication of acute otitis media. Pain is rarely present. All three types of otitis media may be associated with hearing loss. If children with hearing loss due to OME do not learn sign language, it may affect their ability to learn.

A burn is an injury to skin, or other tissues, caused by heat, cold, electricity, chemicals, friction, or ultraviolet radiation. Most burns are due to heat from hot liquids, solids, or fire. Burns occur mainly in the home or the workplace. In the home, risks are associated with domestic kitchens, including stoves, flames, and hot liquids. In the workplace, risks are associated with fire and chemical and electric burns. Alcoholism and smoking are other risk factors. Burns can also occur as a result of self-harm or violence between people (assault).

An ulcer is a sore on the skin or a mucous membrane, accompanied by the disintegration of tissue. Ulcers can result in complete loss of the epidermis and often portions of the dermis and even subcutaneous fat. Ulcers are most common on the skin of the lower extremities and in the gastrointestinal tract. An ulcer that appears on the skin is often visible as an inflamed tissue with an area of reddened skin. A skin ulcer is often visible in the event of exposure to heat or cold, irritation, or a problem with blood circulation.

<span class="mw-page-title-main">Wound</span> Acute injury from laceration, puncture, blunt force, or compression

A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. Wounds can either be the sudden result of direct trauma, or can develop slowly over time due to underlying disease processes such as diabetes mellitus, venous/arterial insufficiency, or immunologic disease. Wounds can vary greatly in their appearance depending on wound location, injury mechanism, depth of injury, timing of onset, and wound sterility, among other factors. Treatment strategies for wounds will vary based on the classification of the wound, therefore it is essential that wounds be thoroughly evaluated by a healthcare professional for proper management. In normal physiology, all wounds will undergo a series of steps collectively known as the wound healing process, which include hemostasis, inflammation, proliferation, and tissue remodeling. Age, tissue oxygenation, stress, underlying medical conditions, and certain medications are just a few of the many factors known to affect the rate of wound healing.

<span class="mw-page-title-main">Venous ulcer</span> Medical condition

Venous ulcer is defined by the American Venous Forum as "a full-thickness defect of skin, most frequently in the ankle region, that fails to heal spontaneously and is sustained by chronic venous disease, based on venous duplex ultrasound testing." Venous ulcers are wounds that are thought to occur due to improper functioning of venous valves, usually of the legs. They are an important cause of chronic wounds, affecting 1% of the population. Venous ulcers develop mostly along the medial distal leg, and can be painful with negative effects on quality of life.

A chronic wound is a wound that does not heal in an orderly set of stages and in a predictable amount of time the way most wounds do; wounds that do not heal within three months are often considered chronic. Chronic wounds seem to be detained in one or more of the phases of wound healing. For example, chronic wounds often remain in the inflammatory stage for too long. To overcome that stage and jump-start the healing process, a number of factors need to be addressed such as bacterial burden, necrotic tissue, and moisture balance of the whole wound. In acute wounds, there is a precise balance between production and degradation of molecules such as collagen; in chronic wounds this balance is lost and degradation plays too large a role.

<span class="mw-page-title-main">Negative-pressure wound therapy</span> Therapeutic technique

Negative-pressure wound therapy (NPWT), also known as a vacuum assisted closure (VAC), is a therapeutic technique using a suction pump, tubing, and a dressing to remove excess exudate and promote healing in acute or chronic wounds and second- and third-degree burns. The therapy involves the controlled application of sub-atmospheric pressure to the local wound environment using a sealed wound dressing connected to a vacuum pump. The use of this technique in wound management started in the 1990s and this technique is often recommended for treatment of a range of wounds including dehisced surgical wounds, closed surgical wounds, open abdominal wounds, open fractures, pressure injuries or pressure ulcers, diabetic foot ulcers, venous insufficiency ulcers, some types of skin grafts, burns, sternal wounds. It may also be considered after a clean surgery in a person who is obese.

A hydrocolloid dressing is an opaque or transparent dressing for wounds. A hydrocolloid dressing is biodegradable, breathable, and depending on the dressing selected, may adhere to the skin, so no separate taping is needed.

<span class="mw-page-title-main">Postpartum bleeding</span> Loss of blood following childbirth

Postpartum bleeding or postpartum hemorrhage (PPH) is often defined as the loss of more than 500 ml or 1,000 ml of blood following childbirth. Some have added the requirement that there also be signs or symptoms of low blood volume for the condition to exist. Signs and symptoms may initially include: an increased heart rate, feeling faint upon standing, and an increased breathing rate. As more blood is lost, the patient may feel cold, blood pressure may drop, and they may become restless or unconscious. In severe cases circulatory collapse, disseminated intravascular coagulation and death can occur. The condition can occur up to twelve weeks following delivery in the secondary form. The most common cause is poor contraction of the uterus following childbirth. Not all of the placenta being delivered, a tear of the uterus, or poor blood clotting are other possible causes. It occurs more commonly in those who already have a low amount of red blood, are Asian, have a larger fetus or more than one fetus, are obese or are older than 40 years of age. It also occurs more commonly following caesarean sections, those in whom medications are used to start labor, those requiring the use of a vacuum or forceps, and those who have an episiotomy.

An open fracture, also called a compound fracture, is a type of bone fracture that has an open wound in the skin near the fractured bone. The skin wound is usually caused by the bone breaking through the surface of the skin. An open fracture can be life threatening or limb-threatening due to the risk of a deep infection and/or bleeding. Open fractures are often caused by high energy trauma such as road traffic accidents and are associated with a high degree of damage to the bone and nearby soft tissue. Other potential complications include nerve damage or impaired bone healing, including malunion or nonunion. The severity of open fractures can vary. For diagnosing and classifying open fractures, Gustilo-Anderson open fracture classification is the most commonly used method. This classification system can also be used to guide treatment, and to predict clinical outcomes. Advanced trauma life support is the first line of action in dealing with open fractures and to rule out other life-threatening condition in cases of trauma. The person is also administered antibiotics for at least 24 hours to reduce the risk of an infection.

<span class="mw-page-title-main">Diabetic foot</span> Medical condition

A diabetic foot disease is any condition that results directly from peripheral artery disease (PAD) or sensory neuropathy affecting the feet of people living with diabetes. Diabetic foot conditions can be acute or chronic complications of diabetes. Presence of several characteristic diabetic foot pathologies such as infection, diabetic foot ulcer and neuropathic osteoarthropathy is called diabetic foot syndrome. The resulting bone deformity is known as Charcot foot.

<span class="mw-page-title-main">Diabetic foot ulcer</span> Medical condition

Diabetic foot ulcer is a breakdown of the skin and sometimes deeper tissues of the foot that leads to sore formation. It may occur due to a variety of mechanisms. It is thought to occur due to abnormal pressure or mechanical stress chronically applied to the foot, usually with concomitant predisposing conditions such as peripheral sensory neuropathy, peripheral motor neuropathy, autonomic neuropathy or peripheral arterial disease. It is a major complication of diabetes mellitus, and it is a type of diabetic foot disease. Secondary complications to the ulcer, such as infection of the skin or subcutaneous tissue, bone infection, gangrene or sepsis are possible, often leading to amputation.

Postoperative wounds are those wounds acquired during surgical procedures. Postoperative wound healing occurs after surgery and normally follows distinct bodily reactions: the inflammatory response, the proliferation of cells and tissues that initiate healing, and the final remodeling. Postoperative wounds are different from other wounds in that they are anticipated and treatment is usually standardized depending on the type of surgery performed. Since the wounds are 'predicted' actions can be taken beforehand and after surgery that can reduce complications and promote healing.
