A wound is a rapid onset of injury that involves lacerated or punctured skin (an open wound), or a contusion (a closed wound) from blunt force trauma or compression. In pathology, a wound is an acute injury that damages the epidermis of the skin. To heal a wound (to regenerate a tissue to its original state), the body undertakes a series of actions collectively known as the wound healing process.

Bacterial infection of wound can impede the healing process and lead to life-threatening complications. Scientists at Sheffield University have used light to rapidly detect the presence of bacteria, by developing a portable kit in which specially designed molecules emit a light signal when bound to bacteria. Current laboratory-based detection of bacteria can take hours or days.[6]

Wounds that are not healing should be investigated to find the causes; many microbiological agents may be responsible. The basic workup includes evaluating the wound, its extent and severity. Cultures are usually obtained both from the wound site and blood. X-rays are obtained and a tetanus shot may be administered if there is any doubt about prior vaccination.[7]

Although diabetes can ravage the body in many ways, non-healing ulcers on the feet and lower legs are common outward manifestations of the disease. Also, diabetics often experience nerve damage in their feet and legs, allowing small wounds or irritations to develop without awareness. Given the abnormalities of the microvasculature and other side effects of diabetes, these wounds take a long time to heal and require a specialized treatment approach for proper healing.

As many as 75% of diabetic patients will eventually develop foot ulcers, and recurrence within five years is 70%. If not aggressively treated, these wounds can lead to amputations. It is estimated that every 30 seconds a lower limb is amputated somewhere in the world because of a diabetic wound. Amputation often triggers a downward spiral of declining quality of life, frequently leading to disability and death. In fact, only about one third of diabetic amputees will live more than five years, a survival rate equivalent to that of many cancers.

Many of these lower extremity amputations can be prevented through an interdisciplinary approach to treatment involving a variety of advanced therapies and techniques, such as debridement, hyperbaric oxygen treatment therapy, dressing selection, special shoes, and patient education. When wounds persist, a specialized approach is required for healing.[8]

Different types of water (such as tap water, distilled water and cooled boiled water) and other solutions (such as saline solution) are commonly used to clean wounds.[10] However, only a limited number of studies have investigated cleaning wounds before closure.[10] A 2022 systematic review brought together evidence from 13 randomised controlled trials (2504 total participants). These studies compared different types of water and solutions for cleaning wounds with each other or with no wound cleaning.[10] It is not clear which, if any, types of water or solution are more effective for helping wounds to heal, reducing pain, reducing treatment costs and improving patient satisfaction.[10]

Evidence is insufficient to conclude whether cleaning wounds is beneficial or whether wound cleaning solutions (polyhexamethylene biguanide, aqueous oxygen peroxide, etc.) are better than sterile water or saline solutions to help venous leg ulcers heal.[13] It is also uncertain whether the choice of cleaning solution or method of application makes any difference to venous leg ulcer healing.[13]

If a person presents to a healthcare center within 6 hours of a laceration they are typically closed immediately after evaluating and cleaning the wound. After this point in time, however, there is a theoretical concern of increased risks of infection if closed immediately.[14] Thus some healthcare providers may delay closure while others may be willing to immediately close up to 24 hours after the injury.[14] Using clean non-sterile gloves is equivalent to using sterile gloves during wound closure.[15]

If closure of a wound is decided upon a number of techniques can be used. These include bandages, a cyanoacrylate glue, staples, and sutures. Absorbable sutures have the benefit over non absorbable sutures of not requiring removal. They are often preferred in children.[16] Buffering the pH of lidocaine makes the injection less painful.[17]Adhesive glue and sutures have comparable cosmetic outcomes for minor lacerations

In the case of clean surgical wounds, there is no evidence that the use of topical antibiotics reduces infection rates in comparison with non-antibiotic ointment or no ointment at all.[21] Antibiotic ointments can irritate the skin, slow healing, and greatly increase the risk of developing contact dermatitis and antibiotic resistance.[21] Because of this, they should only be used when a person shows signs of infection and not as a preventative.[21]

There is moderate evidence that honey is more effective than antiseptic followed by gauze for healing wounds infected after surgical operations. There is a lack of quality evidence relating to the use of honey on other types of wounds, such as minor acute wounds, mixed acute and chronic wounds, pressure ulcers, Fournier's gangrene, venous leg ulcers, diabetic foot ulcers and Leishmaniasis.[24]

There is no good evidence that therapeutic touch is useful in healing.[25] More than 400 species of plants are identified as potentially useful for wound healing.[26] Only three randomized controlled trials, however, have been done for the treatment of burns.[27]

From the Classical Period to the Medieval Period, the body and the soul were believed to be intimately connected, based on several theories put forth by the philosopher Plato. Wounds on the body were believed to correlate with wounds to the soul and vice versa; wounds were seen as an outward sign of an inward illness. Thus, a man who was wounded physically in a serious way was said to be hindered not only physically but spiritually as well. If the soul was wounded, that wound may also eventually become physically manifest, revealing the true state of the soul.[28] Wounds were also seen as writing on the "tablet" of the body. Wounds acquired in war, for example, told the story of a soldier in a form which all could see and understand, and the wounds of a martyr told the story of their faith.[28]

The risk for injury during and after a hurricane and other natural disasters is high. Flood waters and standing waters pose various risks, including infectious diseases, chemical hazards and injuries. Prompt first aid can help heal small wounds and prevent infection.

If you have wounds, you should be evaluated for a tetanus immunization. If you receive a puncture wound or a wound contaminated with feces, soil, or saliva, have a health care professional determine whether a tetanus booster is necessary based on individual records.

An open wound is an injury involving an external or internal break in body tissue, usually involving the skin. Nearly everyone will experience an open wound at some point in their life. Most open wounds are minor and can be treated at home.

Your doctor may use different techniques to treat your open wound. After cleaning and possibly numbing the area, your doctor may close the wound using skin glue, sutures, or stitches. You may receive a tetanus shot if you have a puncture wound.

Depending on the location of your wound and the potential for infection, your doctor may not close the wound and let it heal naturally. This is known as healing by secondary intention, meaning from the base of the wound to the superficial epidermis.

Your doctor will drain or debride the wound and often prescribe an antibiotic if bacterial infection develops. In serious cases, you may need surgery to remove infected tissue and sometimes the surrounding tissue as well.

Damage or disruption of living tissue's cellular, anatomical, and/or functional continuum defines a wound. Before treatment, the exact cause, location, and type of wound must be assessed to provide appropriate care. Each clinician will have widely differing and distinct opinions on wound therapy depending on prior experiences. Given that non-healing wounds affect millions of people in the United States impacting a significant percentage of persons 65 years and older, minimizing wound complications is essential in the current healthcare environment. This activity addresses protocol for wound assessment for the interprofessional team during initial and subsequent wound assessments to best classify and treat a wound to enhance outcomes.

Damage or disruption of living tissue's cellular, anatomical, and/or functional integrity defines a wound.[1] Acute and chronic wounds are technically categorized by the time interval from the index injury and, more importantly, by the evidence of physiological impairment.[2] Accordingly, specific treatments, including biofilms, would be planned to address the management of chronic wounds with an impaired physiological outcome.[1] Before treatment, the exact cause, location, and type of wound must be assessed to provide appropriate care. Each clinician will have widely differing and distinct opinions on wound therapy depending on prior experiences. An ostomy nurse will have a completely different approach to wound care than an orthopedic surgeon dealing with an open fracture during a trauma. Both will be far different from a dermatologist who treats burn victims. Nevertheless, each of these healthcare providers is performing wound care. Since non-healing wounds affect millions of people in the United States, impacting a significant percentage of persons 65 years and older, minimizing wound complications is essential in the current healthcare environment.[3] 2351a5e196
