Dakin's solution. Dakin's solution is a dilute solution of sodium hypochlorite (0.4% to 0.5%) and other stabilizing ingredients, traditionally used as an antiseptic, e.g. to cleanse wounds in order to prevent infection. [1] The preparation was for a time called also Carrel–Dakin solution or Carrel–Dakin fluid. [citation needed]
A typical wetting solution molecule consists of a hydrophilic head and long hydrophobic tail. (From top to bottom: non-ionic, anionic, cationic and zwitterionic.) Wetting solutions are liquids containing active chemical compounds that minimise the distance between two immiscible phases by lowering the surface tension to induce optimal spreading.
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 history of wound care spans from prehistory to modern medicine. Wounds naturally heal by themselves, but hunter-gatherers would have noticed several factors and certain herbal remedies would speed up or assist the process, especially if it was grievous. In ancient history, this was followed by the realisation of the necessity of hygiene and ...
Timing is important to wound healing. Critically, the timing of wound re-epithelialization can decide the outcome of the healing. [11] If the epithelization of tissue over a denuded area is slow, a scar will form over many weeks, or months; [12] [13] If the epithelization of a wounded area is fast, the healing will result in regeneration.
The word "surfactant" is a blend of surface-active agent, [1] coined c. 1950. [2] As they consist of a water-repellent and a water-attracting part, they enable water and oil to mix; they can form foam and facilitate the detachment of dirt. Surfactants are among the most widespread and commercially important chemicals.
Granulation, Granular material, Mineral dust, Pattern recognition, Dynamic light scattering. v. t. e. Granulation is the process of forming grains or granules from a powdery or solid substance, producing a granular material. It is applied in several technological processes in the chemical and pharmaceutical industries.
Wetting is the ability of a liquid to displace gas to maintain contact with a solid surface, resulting from intermolecular interactions when the two are brought together. [1] This happens in presence of a gaseous phase or another liquid phase not miscible with the first one.
