3.13. Classification of Wounds: Vasculogenic Wounds: Classification and Treatment

Página 16

In the health area, especially in nursing, the classification and treatment of wounds are crucial topics for the effective care of patients. Vasculogenic wounds, in particular, are a common and challenging type of wound that requires specialist knowledge to treat correctly. In this chapter, we will explore the classification and treatment of vasculogenic wounds.

Vasculogenic wounds are wounds that occur due to inadequate blood circulation, whether due to arterial or venous insufficiency or a combination of both. They are classified into two main types: venous ulcers and arterial ulcers.

Venous Ulcers

Venous ulcers, also known as stasis ulcers, are the most common type of vasculogenic wounds, accounting for about 70% of all leg ulcers. They occur when the valves in the leg veins do not work properly, causing blood to pool and increase venous pressure, resulting in damage to the skin and underlying tissues.

Venous ulcers are usually found on the lower leg, above the ankle. They are characterized by an irregular border, pink or red base, and can produce a significant amount of exudate. Pain is usually mild to moderate and improves when the leg is elevated.

Arterial Ulcers

Arterial ulcers, on the other hand, occur due to arterial insufficiency, where blood flow to the extremities is insufficient, leading to a lack of oxygen and nutrients needed for skin and tissue health. They are less common than venous ulcers, but they are more painful and difficult to treat.

Arterial ulcers are usually found on the feet, especially on the heels, tips of the toes, and areas where bones are prominent. They are characterized by a well-defined border, pale or black base, and produce little or no exudate. The pain is usually severe and worsens when the leg is elevated.

Treatment

Treatment of vasculogenic wounds involves a multifaceted approach that includes control of the underlying cause, local wound care, pain relief, and prevention of complications.

For venous ulcers, the main treatment is compression to help improve venous flow. This may include compression bandages, compression stockings, or pneumatic compression devices. The wound should be cleaned regularly with normal saline and covered with a moist dressing. Pain relief can be achieved with oral or topical analgesics.

Arterial ulcers require a slightly different approach. The main aim is to improve arterial circulation, which may require procedures such as angioplasty or bypass surgery. The wound should be cleaned with normal saline and covered with a dressing that maintains a moist environment. Pain is usually treated with oral analgesics.

In both cases, preventing complications such as infection is crucial. This can be done by regularly cleaning the wound, using antimicrobial dressings if necessary, and carefully monitoring for signs of infection.

In conclusion, the effective care of vasculogenic wounds requires a solid knowledge of the classification and treatment of these wounds. We hope this chapter has provided useful insight into this important topic in nursing.
