VAC Therapy
Negative-pressure wound therapy (NPWT), also known as a vacuum assisted closure (VAC), is a therapeutic technique using a suction (medicine), suction pump, tubing, and a dressing (medical), dressing to remove excess wound exudate and to promote healing in acute or chronic wounds and Burn, second- and third-degree burns. 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 Wound dehiscence, dehisced surgical wounds, closed surgical wounds, open abdominal wounds, open fractures, pressure injuries or pressure ulcers, diabetic foot ulcers, Venous insufficiency ulceration, venous insufficiency ulcers, some types of skin grafts, burns, and sternal wounds. It may also be considered after a clean surgery in a person who is obese. NPWT is performed by applying a sub-atmospheric vacuum through a special sealed dressing. The continued vacuum draws out edema, fluid from the wound and increases ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eschar
Eschar (; ; ; or ''an'' eschar) is a slough or piece of necrosis, dead tissue that is cast off from the surface of the skin, particularly after a Burn, burn injury, but also seen in gangrene, Ulcer (dermatology), ulcer, mycosis, fungal infections, Loxoscelism, necrotizing spider bite wounds, tick bites associated with spotted fevers and exposure to cutaneous anthrax. The term ‘eschar’ is not interchangeable with ‘scab’. An eschar contains necrotic tissue whereas a scab is composed of dried blood and exudate. Black eschars are most frequently attributed in medicine to cutaneous anthrax (infection by ''Bacillus anthracis''), which may be contracted through herd animal exposure and also from ''Pasteurella multocida'' exposure in cats and rabbits. A newly identified human rickettsial infection, ''R. parkeri'' rickettsiosis, can be differentiated from Rocky Mountain spotted fever by the presence of an eschar at the site of inoculation. Eschar is sometimes called a ''black w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fistula
In anatomy, a fistula (: fistulas or fistulae ; from Latin ''fistula'', "tube, pipe") is an abnormal connection (i.e. tube) joining two hollow spaces (technically, two epithelialized surfaces), such as blood vessels, intestines, or other hollow organs to each other, often resulting in an abnormal flow of fluid from one space to the other. An anal fistula connects the anal canal to the perianal skin. An anovaginal or rectovaginal fistula is a hole joining the anus or rectum to the vagina. A colovaginal fistula joins the space in the colon to that in the vagina. A urinary tract fistula is an abnormal opening in the urinary tract or an abnormal connection between the urinary tract and another organ. An abnormal communication (i.e. hole or tube) between the bladder and the uterus is called a vesicouterine fistula, while if it is between the bladder and the vagina it is known as a vesicovaginal fistula, and if between the urethra and the vagina: a urethrovaginal fistu ...

Osteomyelitis
Osteomyelitis (OM) is the infectious inflammation of bone marrow. Symptoms may include pain in a specific bone with overlying redness, fever, and weakness. The feet, spine, and hips are the most commonly involved bones in adults. The cause is usually a bacterial infection, but rarely can be a fungal infection. It may occur by spread from the blood or from surrounding tissue. Risks for developing osteomyelitis include diabetes, intravenous drug use, prior splenectomy, removal of the spleen, and trauma to the area. Diagnosis is typically suspected based on symptoms and basic laboratory tests as C-reactive protein and erythrocyte sedimentation rate. This is because plain radiographs are unremarkable in the first few days following acute infection. Diagnosis is further confirmed by blood tests, medical imaging, or bone biopsy. Treatment of bacterial osteomyelitis often involves both antimicrobials and surgery. Treatment outcomes of bacterial osteomyelitis are generally good when t ...

Contraindications
In medicine, a contraindication is a condition (a situation or factor) that serves as a reason not to take a certain medical treatment due to the harm that it would cause the patient. Contraindication is the opposite of indication, which is a reason to use a certain treatment. Absolute contraindications are contraindications for which there are no reasonable circumstances for undertaking a course of action (that is, overriding the prohibition). For example: * Children and teenagers with viral infections should not be given aspirin because of the risk of Reye syndrome. * A person with an anaphylactic food allergy should never eat the food to which they are allergic. * A person with hemochromatosis should not be administered iron preparations. * Some medications are so teratogenic that they are absolutely contraindicated in pregnancy; examples include thalidomide and isotretinoin. Relative contraindications are contraindications for circumstances in which the patient is at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gauze
Gauze is a thin, translucent Textile, fabric with a wikt:loose, loose open Weaving, weave. In technical terms, "gauze" is a weave structure in which the weft yarns are arranged in pairs and are crossed before and after each Warp (weaving), warp yarn, keeping the weft firmly in place. This weave structure is used to add stability to the fabric, which is important when using fine yarns loosely spaced. However, this weave structure can be used with any weight of yarn, and can be seen in some rustic textiles made from coarse hand-spun plant fiber yarns. Gauze is widely used for medical dressings. Gauze can also be made of non-woven fabric. Etymology and history The word ''gauze'' came into English in the 16th century via French ''gaze'', beyond which its history is uncertain. Most scholars trace ''gauze'' to a Persian language, Persian word for thin cloth or an Arabic word for raw silk. The Philip III, Bishop of Fermo#Hungary, 1279 Council of Baden banned clergy from wearing " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Foam
Foams are two-phase materials science, material systems where a gas is dispersed in a second, non-gaseous material, specifically, in which gas cells are enclosed by a distinct liquid or solid material. Note, this source focuses only on liquid foams. Note, this source also focuses on liquid foams. Foam "may contain more or less liquid [or solid] according to circumstances", although in the case of gas-liquid foams, the gas occupies most of the volume. In most foams, the volume of gas is large, with thin films of liquid or solid separating the regions of gas. Etymology The word derives from the Old High German, medieval German and otherwise obsolete ''veim'', in reference to the "frothy head forming in the glass once the beer has been freshly poured" (cf. ''ausgefeimt''). Structure A foam is, in many cases, a multi-scale system. One scale is the bubble: materials science, material foams are typically randomness, disordered and have a variety of bubble sizes. At larger siz ...

Vacuum Pump
A vacuum pump is a type of pump device that draws gas particles from a sealed volume in order to leave behind a partial vacuum. The first vacuum pump was invented in 1650 by Otto von Guericke, and was preceded by the suction pump, which dates to antiquity. History Early pumps The predecessor to the vacuum pump was the suction pump. Dual-action suction pumps were found in the city of Pompeii. Arabic engineer Al-Jazari later described dual-action suction pumps as part of water-raising machines in the 13th century. He also said that a suction pump was used in siphons to discharge Greek fire. The suction pump later appeared in medieval Europe from the 15th century.

Periwound
The periwound (also peri-wound) is tissue surrounding a wound. Periwound area is traditionally limited to 4 cm outside the wound's edge but can extend beyond this limit if outward damage to the skin is present. Periwound assessment is an important step of wound assessment before wound treatment is prescribed. Function and characteristics Healthy periwound is an immediate barrier surrounding the wound bed that can perform all the regular functions of skin – the body's largest organ – such as absorption, excretion, protection, secretion, thermoregulation, pigment production, sensory perception and immunity. Healthy periwound maintains all the physical characteristics of skin: elasticity, surface integrity, color and texture. However, periwound can become compromised and negatively affect the healing progress of the wound. Periwound issues Periwound issues affect the integrity and healthy functionality of the skin surrounding the wound and may include maceration, excoriatio ...
