What is a wound treatment for negative pressure?
wound therapy (NPWT) is a technique used to facilitate faster wound healing. The basic goal of NPWT is to use a suction or vacuum procedure to draw excess fluid from the wound, thereby improving the circulation and disposal of cell waste. This technique is used for several types of wounds, especially large and chronic wounds, as well as burns. Based on the type of wound, NPWT can use the use of gauze, foam cushions or special sponges located on top or inside the wound and hose system associated with a vacuum pump.
It is generally assumed that a negative pressure blow benefit for healing injuries in several areas. It creates a humid and closed environment of the wound, balances fluids, removes dead tissue, increases circulation, reduces bacteria and promotes the growth of white blood cells. However, the physiological effects of the wound therapy are still fully understood and some asked if it really accelerates wounding faster than other methods.
Without knowing the details of how vacuum pressure causes different biological mechanisms to focus, it is difficult to determine the most suitable protocol for the use of technology in individual patients. However, many healthcare professionals have been successful with NPWT and simply experiment with the time during which the vacuum pressure and the level of intensity with which it is served is. The bandage changes occur when therapy ends with negative pressure, which can be anywhere from every 48 to 72 hours, and doctors select the spongy material used to absorb fluids based on what size and density of pores is suitable for a particular wound.
The common setting for negative pressure therapy is to reduce a piece of porous black polyurethane foam designed for NPWT to match the size and shape of the wound. Then the tubkana is located the upper part of the foam or inside the foam and over the clean piece of plastic adhesive is placed over both to hold the foam and the tube against the wound to ensure that everything isCorrectly sealed. The tube is connected to the vacuum pump, the pump is on, then the pump sucks the excess liquid from the wound and flows into the attached container for the time of the prescribed time. Sowing can be constant or periodic, depending on the type of wound and type of connected vacuum pump or intake device.
