  Pressure injuries are localized skin and soft tissue injuries that develop due to prolonged pressure exerted over specific areas of the body, typically bony prominences. These injuries demand prompt treatment to prevent potential lethal complications. Evaluation and treatment options must consider the latest guidelines and classifications by the National Pressure Injury Advisory Panel and the International Statistical Classification of Diseases and Related Health Problems (ICD-11). […] Pressure injuries, also termed bedsores, decubitus ulcers, or pressure ulcers, are localized skin and soft tissue injuries that form as a result of prolonged pressure and shear, usually exerted over bony prominences. These ulcers are present 70% of the time at the sacrum, ischial tuberosity, and greater trochanter. However, they can also occur in the occiput, scapula, elbow, heel, lateral malleolus, shoulder, and ear.

  https://www.mayoclinic.org/diseases-conditions/bed-sores/symptoms-causes/syc-20355893

  Bedsores are areas of damaged skin and tissue caused by sustained pressure that reduces blood flow to vulnerable areas of the body. […] Bedsores also are called pressure ulcers, pressure injuries and decubitus ulcers. […] Bedsores can arise over hours or days. Most sores heal with treatment, but some never heal completely. […] Bedsores fall into one of several stages based on their depth, how serious they are and other features. The degree of skin and tissue damage ranges from inflamed, unbroken skin to a deep injury involving muscle and bone. […] If you notice warning signs of a bedsore, change your position to ease pressure on the area. If the area doesn’t improve in 24 to 48 hours, contact your healthcare professional. […] Pressure against the skin that limits blood flow to the skin causes bedsores. Limited movement can make skin prone to damage and cause bedsores.

• #3 Bedsores (Pressure Ulcers): Symptoms, Staging & Treatment

  https://my.clevelandclinic.org/health/diseases/17823-bedsores-pressure-injuries

  Bedsores are wounds that occur from prolonged pressure on your skin. People who are immobile for long periods, such as those who are bedridden or use a wheelchair, are most at risk for bedsores. These painful wounds, or pressure ulcers, can grow large and lead to infections. In some instances, bedsores can be life-threatening. […] Bedsores occur when pressure reduces or cuts off blood flow to your skin. This lack of blood flow can cause a pressure wound injury to develop in as little as two hours. Skin cells on your epidermis (your skins outer layer) start to die. As the dead cells break down, a pressure ulcer injury forms. […] Healthcare providers diagnose and stage bedsores based on their appearance. Your provider will photograph the sore to monitor wound healing. […] Stages of bedsores or pressure ulcers include: Stage 1: Your skin looks red or pink, but there isnt an open wound.

  Pressure sores are areas of skin damage resulting from a lack of blood flow due to prolonged pressure. […] The diagnosis is usually based on a physical examination. […] Doctors can usually diagnose pressure sores by doing a physical examination and noting the appearance and location of the sores. […] Because the depth and severity of pressure sores are difficult to determine, doctors or specially trained health care professionals stage and photograph pressure sores to monitor how they progress or heal. […] Doctors use specific criteria to determine how a pressure sore is healing. […] When pressure sores do not heal, doctors often suspect a complication such as an infection. If osteomyelitis is suspected, doctors do blood tests and often the imaging test magnetic resonance imaging (MRI). To confirm osteomyelitis, doctors may need to take a small sample (biopsy) of bone to see if bacteria grow from it (culture).

  You may know pressure sores by their more common name: bedsores. Also sometimes called pressure ulcers, they happen when you lie or sit in one position too long and the weight of your body against the surface of the bed or chair cuts off blood supply. […] Your doctor may talk about the „stage” of your pressure sores. The stages are based on how deep the sores are, which can affect how they’re treated. […] To diagnose a pressure sore, your doctor will examine your skin. They might ask questions like: When did the sore appear? Does it hurt? How often do you change positions? Have you ever had a pressure sore before? […] Your doctor will consider your symptoms. Then they’ll determine whether you have a pressure sore, and if so, what stage it’s in. […] If your doctor is worried you might have an infection, they might do: Blood tests, Biopsies to take a sample of tissue for testing, Imaging, such as an X-ray or MRI, to get a picture of what’s happening under your skin.

  The 2 latest and most acceptable classifications were defined by the NPIAP and the International Statistical Classification of Diseases and Related Health Problems (ICD-11), released in 2019 and 2018, respectively. […] The initial evaluation of patients with pressure ulcers involves a detailed history. The clinician should gather the following: Duration of immobility or being bedridden; Duration of hospital stay; Associated medical cause that has caused the injury (eg, paraplegia, quadriplegia, stroke, road traffic accident resulting in immobility); The natural history of the injury and the site at which it first developed. Duration of injury and any size increases should also be noted; A brief history of any systemic diseases is also necessary. Diseases like diabetes mellitus, peripheral vascular disease, and malignancy prevent or slow wound healing.

  A pressure ulcer is a localized injury to the skin or underlying tissue, usually over a bony prominence, as a result of unrelieved pressure. […] When an ulcer occurs, documentation of each ulcer (i.e., size, location, eschar and granulation tissue, exudate, odor, sinus tracts, undermining, and infection) and appropriate staging (I through IV) are essential to the wound assessment. […] The physician should note the number, location, and size (length, width, and depth) of ulcers and assess for the presence of exudate, odor, sinus tracts, necrosis or eschar formation, tunneling, undermining, infection, healing (granulation and epithelialization), and wound margins. […] The stage of an ulcer cannot be determined until enough slough or eschar is removed to expose the base of the wound. […] The management of pressure ulcers is interdisciplinary, including primary care physicians, dermatologists, infectious disease consultants, social workers, psychologists, dietitians, podiatrists, home and wound-care nurses, rehabilitation professionals, and surgeons.

• #8 Pressure Ulcers: Prevention, Evaluation, and Management | AAFP

  https://www.aafp.org/pubs/afp/issues/2008/1115/p1186.html/1000

  The basic components of pressure ulcer management are reducing or relieving pressure on the skin, debriding necrotic tissue, cleansing the wound, managing bacterial load and colonization, and selecting a wound dressing. […] Necrotic tissue promotes bacterial growth and impairs wound healing, and it should be debrided until eschar is removed and granulation tissue is present. […] A trial of topical antibiotics, such as silver sulfadiazine cream (Silvadene), should be used for up to two weeks for clean ulcers that are not healing properly after two to four weeks of optimal wound care. […] Surgical consultation should be obtained for patients with clean stage III or IV ulcers that do not respond to optimal patient care or when quality of life would be improved with rapid wound closure. […] Growth factors (e.g., platelet-derived growth factor becaplermin [Regranex]) and vacuum-assisted closure for recalcitrant stage III and IV ulcers are emerging management options.

  The stages are as follows: Stage 1: The skin is intact with nonblanchable erythema. Stage 2: There is partial-thickness skin loss involving the epidermis and dermis. Stage 3: A full-thickness loss of skin extends to the subcutaneous tissue but does not cross the fascia beneath it. Slough or eschar may be visible, and the lesion may be foul-smelling. Stage 4: Full-thickness skin loss extends through the fascia with considerable tissue loss. There may be muscle, bone, tendon, or joint involvement.

• #14 Pressure Injuries (Pressure Ulcers) and Wound Care: Practice Essentials, Background, Anatomy

  https://emedicine.medscape.com/article/190115-overview

  Although the terms decubitus ulcer, pressure sore, and pressure ulcer have often been used interchangeably, the National Pressure Injury Advisory Panel (NPIAP; formerly the National Pressure Ulcer Advisory Panel [NPUAP]) has stated that pressure injury the best term to use, given that open ulceration does not always occur. According to the NPIAP, a pressure injury is localized damage to the skin and underlying soft tissue, usually over a bony prominence or related to a medical or other device. It can present as intact skin or an open ulcer and may be painful. It occurs as a result of intense or prolonged pressure or pressure in combination with shear. […] For the purposes of workup and treatment, it is helpful to stage the pressure injury according to the system promulgated by the NPIAP, as follows: Stage 1 pressure injury – Nonblanchable erythema of intact skin; Stage 2 pressure injury – Partial-thickness skin loss with exposed dermis; Stage 3 pressure injury – Full-thickness skin loss; Stage 4 pressure injury – Full-thickness skin and tissue loss; Unstageable pressure injury – Obscured full-thickness skin and tissue loss; Deep pressure injury – Persistent nonblanchable deep red, maroon or purple discoloration.

  https://www.merckmanuals.com/home/skin-disorders/pressure-sores/pressure-sores

  Pressure sores are areas of skin damage resulting from a lack of blood flow due to prolonged pressure. […] The diagnosis is usually based on a physical examination. […] Doctors can usually diagnose pressure sores by doing a physical examination and noting the appearance and location of the sores. […] Because the depth and severity of pressure sores are difficult to determine, doctors or specially trained health care professionals stage and photograph pressure sores to monitor how they progress or heal. […] Doctors use specific criteria to determine how a pressure sore is healing. […] When pressure sores do not heal, doctors often suspect a complication such as an infection. If osteomyelitis is suspected, doctors do blood tests and often the imaging test magnetic resonance imaging (MRI). To confirm osteomyelitis, doctors may need to take a small sample (biopsy) of bone to see if bacteria grow from it (culture).

In later stages, they can involve deep wounds and carry a higher risk of complications, like infection. […] Pressure ulcers can progress in four stages based on the level of tissue damage. These stages help doctors determine the best course of treatment for a speedy recovery. […] If caught very early and treated properly, these sores can heal in a matter of days. If left untreated, severe bedsores may require years to heal. […] In the second stage, the sore area of your skin has broken through the top layer of skin (epidermis) and some of the layer below (dermis). The break typically creates a shallow, open wound. […] You must seek immediate medical treatment if you have a stage 3 pressure ulcer. These sores need special attention.

In more severe cases, they can extend as far down as the cartilage or bone. […] Your doctor can only determine how deep the wound is after clearing it out. If there’s extensive tissue damage, it will need to be surgically removed. […] These sores are more common among the elderly, people with limited mobility, and people who are bedridden from illness or other conditions.

[…] Your doctor may talk about the „stage” of your pressure sores. The stages are based on how deep the sores are, which can affect how they’re treated. […] To diagnose a pressure sore, your doctor will examine your skin. They might ask questions like: When did the sore appear? Does it hurt? How often do you change positions? Have you ever had a pressure sore before? […] Your doctor will consider your symptoms. Then they’ll determine whether you have a pressure sore, and if so, what stage it’s in. […] If your doctor is worried you might have an infection, they might do: Blood tests, Biopsies to take a sample of tissue for testing, Imaging, such as an X-ray or MRI, to get a picture of what’s happening under your skin.

  Pressure ulcers may develop in any area of the body. However, areas with the most pressure are often at a higher risk. […] Patients admitted to nursing homes with an acute or long term illness and those who are immobile are often at a greater risk of developing pressure sores unless adequate preventive care is taken. […] The ulcer is divided into four stages according to its progression. At the beginning there is erythema of the affected skin. This means the skin is redness over the affected area. […] A stage 1 pressure sore does not blanch on pressure with a gloved finger. The skin is still intact and there is no ulceration. The first sign of a pressure ulcer thus is a change in skin colour that may appear slightly redder or darker than usual. […] Stage 2 involves damage to the skin by formation of an ulcer, a shallow crater or an abrasion or a blister.

  Pressure ulcers also known as decubitus ulcers or bedsores are wounds that result from low blood flow. […] A stage 2 pressure ulcer is one that has progressed to affect both the top and bottom layers of the skin but has not yet affected the fatty tissue beneath. […] When a pressure ulcer reaches the second stage, the sore has broken through the top layer of the skin and part of the layer below. This typically results in a shallow, open wound. […] A stage 2 pressure ulcer may appear as a shallow, crater-like wound or a blister containing a clear or yellow fluid. […] Some symptoms associated with stage 2 pressure ulcers include: pain, an ulcer containing pus or liquid, swelling and discoloration around the sore.

[…] Diagnosing a Stage 3 Bedsore […] Stage 3 bedsore symptoms include a deep, reddish crater that has extended through all skin layers, reaching the fat tissue beneath. […] A stage 3 bedsore, also known as a grade 3 pressure sore, has burrowed past the dermis (the skin’s second layer) and reached the subcutaneous tissue (fat layers) beneath. […] Stage 3 bedsores are quite deep, but tendons, ligaments, muscles, and/or bones will not be visible. If they are, the patient likely has a stage 4 bedsore.

A stage 4 bedsore is a sign of nursing home neglect since it is preventable with proper care. […] A stage 4 bedsore is a deep wound reaching the muscles, ligaments, or bones. It is the most severe form of a bedsore (also called a bed sore, pressure sore, pressure ulcer, or decubitus ulcer.) […] Sadly, a stage 4 pressure ulcer is often a sign of nursing home neglect. Residents of nursing homes may develop these sores if caregivers fail to treat earlier pressure ulcer stages. […] A stage 4 pressure ulcer usually means a nursing home resident has remained in the same position for an extended period of time. […] A doctor determines the stage of a bedsore by its appearance.

  In Stage 2, pressure ulcers have progressed to an open wound. The top layer of skin has worn away and may look like a sore, a scrape, or a broken blister. These are extremely painful for the patient. […] If a pressure ulcer is in stage 3, it has reached into the deeper layers of skin and fat but has not yet damaged the patient’s muscle or bone tissue. […] A stage 4 bedsore means the skin has ulcerated completely away and the injury has started to reach muscle, tendons, or bone. At this point, patients are at risk of developing a bone infection. […] Unstageable pressure injuries are those that are too difficult to stage due to the condition of the wound. They may be covered with necrotic tissue and the base of the wound cannot be seen well enough to assess its progression. […] The longer bedsores are allowed to progress without treatment, the higher the patient’s risk of serious complications becomes. This includes serious skin infections that can reach the blood and result in sepsis, which is a life-threatening condition that requires hospitalization and intensive treatment to reverse.

[…] The physician should note the number, location, and size (length, width, and depth) of ulcers and assess for the presence of exudate, odor, sinus tracts, necrosis or eschar formation, tunneling, undermining, infection, healing (granulation and epithelialization), and wound margins. […] The stage of an ulcer cannot be determined until enough slough or eschar is removed to expose the base of the wound. […] The management of pressure ulcers is interdisciplinary, including primary care physicians, dermatologists, infectious disease consultants, social workers, psychologists, dietitians, podiatrists, home and wound-care nurses, rehabilitation professionals, and surgeons.

  Patients with extensive superficial pressure ulcers, Grade 3 or 4 pressure ulcers or those that are deteriorating should be referred to a specialist service. […] Healing is not usually a fast process. However, as long as the patient has adequate pressure redistribution, good nutrition and appropriate wound management, the ulcer will heal in most cases. […] All pressure ulcers are colonised with bacteria. Most local infection can be managed using antimicrobial wound products; systemic antibiotics should not be used routinely for local infection. […] The presence of pressure ulcers is associated with a two-fold to four-fold increased risk of death but this is because pressure ulcers are a marker for underlying disease severity and other comorbidities.

  Certain lab values may offer insight into the causes of pressure ulcers or the risk for poor healing: Increased white blood cell (WBC) counts indicate inflammation or infection; Low hemoglobin levels indicate less oxygen traveling to tissues; Low platelet counts may complicate wound proliferation and angiogenesis; Low albumin levels indicate decreased protein, which inhibits wound healing; Elevated glucose levels may impact wound healing. […] Pressure ulcers with drainage or signs of infection may require culturing to identify the pathogen and administer the appropriate antibiotic treatment. […] Debridement may be necessary to remove dead, infected, or damaged tissue in order for the tissue to heal successfully. […] A wound care certified nurse should assess complex or chronic pressure ulcers to recommend the appropriate wound care management and treatment plan.
