Complex Wound Management

Venous leg ulcers can be slow to heal; the longer a wound is present, the less likely it is to heal. To move a venous leg ulcer through the phases of wound healing may require more than just basic wound care.

Chronic venous leg ulcers can be prone to chronic inflammation. Changes in the microcirculation down to the capillary level can elevate levels of cytokines and proteases, thus leaving the wound stuck in the inflammatory cycle. Controlling, reducing, or eliminating inflammation is necessary to move the wound toward closure.

Growth factors and cytokines are secreted by the cells and are essential to the complex wound healing and tissue regeneration process. This process involves the interplay of growth factors with chemokines, cytokines, and other signaling molecules. Although there have been numerous advances that have increased our understanding of wound healing, the exact tissue regeneration mechanisms following an injury have yet to be determined.

Angiogenesis: The complex process in which the growth of normal, stable, and functional vessels is critically dependent on the coordinated interplay in space and time of different cell types and growth factors. This process involves the forming of new blood vessels from preexisting vessels by invading the wound clot to organize in a microvascular network throughout granulation tissue.

Autologous cell therapy: A therapeutic intervention that uses an individual’s cells, which are cultured and expanded outside of the body and reintroduced into the donor as a bioengineered skin substitute to aid in wound closure.

Immunomodulation: Therapeutic interventions aimed at modifying the immune response. Healing in chronic and complex wounds can be enhanced with immunomodulating agents.

Chronic wounds pose an ongoing challenge for clinicians, and there needs to be a clearer understanding of the pathophysiology of wound chronicity and treatment modalities available.

If you've ever had a painful red bump after shaving, you've probably chalked this up to razor burn or an ingrown hair. After an irritating day or so, the bumps will likely fade and disappear on their own, and you don't give it any more thought. But what if these bumps just kept growing and became more and more painful? And even worse, what if they developed in sensitive areas such as the axilla or the groin? What if these bumps got so bad, they eventually opened, started to drain, and even formed tracts under the skin? Not only are these bumps painful, but they are also embarrassing. Forget about wearing a sleeveless shirt or bathing suit in the summer. Would people think you had a horrific contagious disease? You go to doctor after doctor, but no one has been able to treat this successfully. The bumps may disappear for some time but then suddenly reappear. They may leave scars that seem to open and close persistently, and at times they may become infected, requiring antibiotic therapy. Finally, you get the diagnosis for this awful condition: hidradenitis suppurativa (HS).

Picture this: you've been seeing a patient in your wound center for the last several months to treat a slowly healing post-operative abdominal wound. The wound has been gradually responding to an assortment of treatments, including initial wound vacuum therapy after the surgery, followed by alginate and now a collagen dressing. The wound is getting smaller and has new granulation tissue at the base. You're actually a bit surprised that it's healing so nicely because the patient has multiple serious chronic illnesses, including severe chronic kidney disease that requires hemodialysis sessions three times per week, type 2 diabetes, morbid obesity, cardiovascular disease, and peripheral vascular disease.

The venous leg ulcer (VLU) is the most common type of chronic leg wound, and it can be challenging to manage. VLUs account for up to 90% of all chronic leg ulcers. Proper diagnosis and treatment planning are key to wound healing outcomes. This fact is particularly true for older adults, who have an annual VLU prevalence of 1.7%.

Fistulas are abnormal connections or passageways between two organs or vessels that do not usually connect. Although they typically develop as a result of an injury or surgery, they can also be caused by infection or inflammation. The World Health Organization estimates that there are between 50,000 and 100,000 new cases of obstetric fistula annually, and the number of all types of fistulas is substantially higher.

Biofilm: this term is frequently used in the wound care space, but biofilm continues to be largely undertreated in wound care. What do the bedside nurse or clinician need to know about biofilm? Should clinicians care less about biofilm on a maintenance or palliative wound versus a wound they are actively trying to heal? Let's address these questions and get to the root of the biofilm in managing complex wound cases.

A vast percentage of wounds become chronically stalled because of mixed etiology and other underlying comorbid medical conditions. This means the wound is multifactorial, and using a singular approach won’t be enough. Lower extremity wounds, for example, can have diabetes, venous and arterial issues, and pressure all as factors playing into the same wound.
