Occlusive dressings come in various forms, including petrolatum gauze, which sticks to the skin surrounding the wound using petrolatum. They can also be used to enhance the penetration and absorption of topically-applied medications, such as ointments and creams.
Gauze dressing is made up of woven or non-woven fibres of cotton, rayon, and polyester. Gauze dressing are capable of absorbing discharge from wound but requires frequent changing. Excessive wound discharge would cause the gauze to adhere to the wound, thus causes pain when trying to remove the gauze from the wound.
Maceration is defined as the softening and breaking down of skin resulting from prolonged exposure to moisture. It was first described by Jean-Martin Charcot in 1877. [1] [2] Maceration is caused by excessive amounts of fluid remaining in contact with the skin or the surface of a wound for extended periods.
The moist conditions produced under the dressing are intended to promote fibrinolysis, angiogenesis and wound healing, without causing softening and breaking down of tissue. The gel which is formed as a result of the absorption of wound exudate is held in place within the structure of the adhesive matrix.
Once applied directly to a recently cleaned wound it has the ability to absorb some moisture or blood from the wound. [4] As the iodine is used up, the dressing loses colour and becomes white. [5] It is typically held in place using gauze and then bandage material. [6]
The holes in his intestines leaked stomach acid and burned away the surrounding tissues and skin, leaving less skin available to eventually stretch over the wound and close it. Colon learned to sop up the excess acid from his exposed intestines with gauze pads and later with a machine that sucked the acid through a tube.
Negative pressure wound therapy device. 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 wound exudate and to promote healing in acute or chronic wounds and second- and third-degree burns.
It was just after 7:30 a.m., when I hit “send” on an email addressed to my husband’s radiologist, physician’s assistant and radiation nurse.
