Surgicel
Surgicel is a hemostatic agent (blood-clot-inducing material) made of an oxidized cellulose polymer (the unit is polyanhydroglucuronic acid), manufactured by the Ethicon subsidiary of Johnson And Johnson. It was introduced into clinical practice in 1947. It is used to control post-surgical bleeding. It is also used by some boxing cutmen A cutman is a person responsible for preventing and treating physical damage to a fighter during the breaks between rounds of a full contact match such as a boxing, kickboxing or a mixed martial arts bout. Cutmen typically handle swelling, nose ... to control bleeding. Surgicel is used extensively in oral and maxillofacial surgery to control intrabony arterial bleeds from the inferior alveolar artery. It is frequently used to stop bleeding following newborn circumcision if pressure alone is inadequate. When placed in the mandibular canal with the inferior alveolar nerve exposed there have been reports of neurotoxic effects. Common sizes includ ...

Hemostatic Agent
An antihemorrhagic (antihæmorrhagic) agent is a substance that promotes hemostasis (stops bleeding). It may also be known as a hemostatic (also spelled haemostatic) agent. Antihemorrhagic agents used in medicine have various mechanisms of action: * Systemic drugs work by inhibiting fibrinolysis or promoting coagulation. * Locally acting hemostatic agents work by causing vasoconstriction or promoting platelet aggregation. Medical uses Hemostatic agents are used during surgical procedures to achieve hemostasis and are categorized as hemostats, sealants and adhesives. They vary based on their mechanism of action, composition, ease of application, adherence to tissue, immunogenicity and cost. These agents permit rapid hemostasis, better visualization of the surgical area, shorter operative times, decreased requirement for transfusions, decreased wound healing time and overall improvement in patient recovery time. Types Systemic There are several classes of antihemorrhagic drug ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clot
A thrombus (plural thrombi), colloquially called a blood clot, is the final product of the blood coagulation step in hemostasis. There are two components to a thrombus: aggregated platelets and red blood cells that form a plug, and a mesh of cross-linked fibrin protein. The substance making up a thrombus is sometimes called cruor. A thrombus is a healthy response to injury intended to stop and prevent further bleeding, but can be harmful in thrombosis, when a clot obstructs blood flow through healthy blood vessels in the circulatory system. In the microcirculation consisting of the very small and smallest blood vessels the capillaries, tiny thrombi known as microclots can obstruct the flow of blood in the capillaries. This can cause a number of problems particularly affecting the alveoli in the lungs of the respiratory system resulting from reduced oxygen supply. Microclots have been found to be a characteristic feature in severe cases of COVID-19, and in long COVID. Mural thr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cellulose
Cellulose is an organic compound with the formula , a polysaccharide consisting of a linear chain of several hundred to many thousands of β(1→4) linked D-glucose units. Cellulose is an important structural component of the primary cell wall of green plants, many forms of algae and the oomycetes. Some species of bacteria secrete it to form biofilms. Cellulose is the most abundant organic polymer on Earth. The cellulose content of cotton fiber is 90%, that of wood is 40–50%, and that of dried hemp is approximately 57%. Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane and rayon. Conversion of cellulose from energy crops into biofuels such as cellulosic ethanol is under development as a renewable fuel source. Cellulose for industrial use is mainly obtained from wood pulp and cotton. Some animals, particularly ruminants and termites, can digest cellulose with the help of ...

Ethicon Inc
Ethicon, Inc. is a subsidiary of Johnson & Johnson. It was incorporated as a separate company under the Johnson & Johnson umbrella in 1949 to expand and diversify the Johnson & Johnson product line. Ethicon has manufactured surgical sutures and wound closure devices since 1887. After World War II, Ethicon's market share in surgical sutures rose from 15% to 70% worldwide. In the United States, the market share is approximately 80%. Ethicon conducts business in 52 countries. Corporate history In 1915, George F. Merson opened a facility in Edinburgh for the manufacturing, packaging and sterilising of catgut, silk and nylon sutures. Johnson & Johnson acquired Mr. Merson's company in 1947, and this was renamed Ethicon Suture Laboratories. In 1953 this became Ethicon Inc. In 1992, Ethicon was restructured, and Ethicon Endo-Surgery became a separate corporate entity. In 2008, Ethicon sold its wound management business to One Equity Partners and became Systagenix Wound Management L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cutmen
A cutman is a person responsible for preventing and treating physical damage to a fighter during the breaks between rounds of a Contact sport#Full-contact, full contact match such as a boxing, kickboxing or a mixed martial arts bout. Cutmen typically handle hematoma, swelling, nosebleeds and lacerations. In addition to degrading a fighter's performance, the rules of combat sports stipulate that these injuries can be a cause for premature match stoppage, counting as a loss to the injured fighter. The cutman is therefore essential to the fighter, and can be a decisive factor in the outcome of the match. The compensation for cutmen varies, generally within 10–15% of the fighter's prize money.Whisler, John (2004)"Battered boxers want Joe Souza in their corner". www.mysanantonio.com. URL last accessed May 9, 2006. For many fighters on a low budget, the cutman duties are performed by their cornerman. While most athletic commissions require cutmen to be licensed, there is usually no fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
