VSD systems have proven highly effective in the context of surgical wounds. When dealing with large and complex surgical incisions, such as those in major abdominal or orthopedic surgeries, the risk of infection and delayed healing is significant. The VSD system works by creating a negative pressure environment over the wound. This negative pressure helps to draw out any accumulated fluids, like blood or serous fluid, that could otherwise serve as a breeding ground for bacteria. For example, in a colorectal surgery with a large abdominal incision, the VSD system can continuously remove the fluid exudate, reducing the likelihood of wound infection. Additionally, it helps to keep the wound edges in close approximation, which is beneficial for proper tissue healing and scar formation. In cases where the surgical wound is at a particularly high risk of infection, perhaps due to the patient’s underlying health conditions or the nature of the surgical procedure, the VSD system can be a crucial adjunct to standard wound care, promoting a more rapid and complication-free healing process.

Chronic wounds present a persistent challenge in the field of wound care. Diabetic ulcers, pressure sores, and venous leg ulcers often resist traditional treatment modalities. VSD systems offer a promising solution. The negative pressure applied by these systems has multiple beneficial effects. Firstly, it stimulates the growth of granulation tissue. In a diabetic ulcer, for instance, the suction helps to recruit cells involved in tissue repair and angiogenesis (formation of new blood vessels). This is vital as diabetic patients often have impaired blood flow and tissue regeneration capabilities. Secondly, the reduction of edema is significant. In venous leg ulcers, where fluid tends to accumulate due to poor venous return, the VSD system can effectively draw out the excess fluid, relieving pressure on the surrounding tissues and improving blood circulation. Finally, the control of infection is a major advantage. By continuously removing bacteria and debris from the wound bed, the VSD system helps to create a cleaner and more sterile environment, allowing the body’s natural healing mechanisms to function more effectively and promoting healing in wounds that have previously been recalcitrant to other forms of treatment.

Complex traumatic wounds resulting from accidents or violent incidents are often accompanied by a significant amount of debris and fluids. VSD systems play a crucial role in their management. The negative pressure exerted by the system is highly efficient in removing debris such as dirt, fragments of clothing, and shattered bone or tissue. For example, in a severe open fracture wound caused by a motor vehicle accident, the VSD system can clear the wound of foreign material and blood clots. This not only reduces the risk of infection but also stabilizes the wound bed. By promoting better approximation of the wound edges and providing a controlled healing environment, the VSD system accelerates the natural healing process. It also helps to minimize the formation of scar tissue and deformities that could otherwise occur due to improper healing of such complex traumatic wounds.
