Alipainekäyttö

Alipainekäyttö, also known as negative pressure therapy or vacuum-assisted closure (VAC), is a medical treatment method used to promote wound healing. It involves applying a controlled negative pressure to a wound bed. This negative pressure is typically generated by a vacuum pump, which is connected to a specialized foam dressing placed over the wound. The foam dressing creates a seal, allowing the pump to draw out fluid and reduce edema.

The mechanism of action for alipainekäyttö is believed to involve several factors. The negative pressure can help to remove exudate, infection, and dead tissue from the wound, creating a cleaner environment conducive to healing. It also draws the wound edges closer together, reducing the size of the wound and potentially promoting granulation tissue formation. Furthermore, the application of negative pressure is thought to increase blood flow to the wound area, which can enhance the delivery of oxygen and nutrients, further supporting the healing process.

Alipainekäyttö is commonly used for a variety of wounds, including chronic ulcers (such as diabetic foot ulcers and pressure ulcers), surgical wounds that have dehisced, and traumatic injuries. It is often employed when conventional wound care methods have not been successful. The treatment requires regular dressing changes and monitoring by healthcare professionals. While generally considered safe, potential complications can include pain, skin irritation, and damage to surrounding healthy tissue if not applied correctly.
