Utilization of a topical autologous blood clot for treatment of pressure ulcers.

Management and treatment of pressure ulcers (PUs) are met with great difficulty due to various factors that cause vulnerability of the soft tissue such as location, limited mobility, increased friction and shearing forces, as well as other comorbidities that may delay or halt wound healing. The topical autologous blood clot therapy (TABCT) is a point-of-care treatment used as a blood clot to assist in recreating and repairing the extracellular matrix (ECM). The mechanism of action consists of reconstruction of the ECM by incorporating into the ulcer, providing protection from further external destruction, while assisting in advancement through the wound healing phases via interaction of necessary growth factors, mediators, and chemokines. This study aims to assess the efficacy of the TABCT in the treatment of PUs in comparison to standard of care (SOC) treatment. Twenty-four patients, 18 years or older, with PUs ranging from stage 1 to 4, were included in this study. TABCT was created by using the patient's own peripheral blood in a point of care setting. Efficacy in percent area reduction (PAR) on weeks 4 and 12 with TABCT over SOC was assessed. Treatment using TABCT in PUs resulted in 77.9% of the patients achieving a 50% PAR on week 4. The mean PAR on week 12 was 96.23% with 45% of the wounds treated with TABCT achieving complete wound closure. TABCT exhibited efficacy in PAR of PUs. In addition, TABCT use prompted granulation tissue formation over vital structures, such as bone, which is often present in later stage PUs. The potential of bringing an affordable, cost-effective, advanced biologic bedside treatment that is efficacious in resolution of these complex wounds has the potential to drastically reduce the burden of treatment on the health system.

Wound Care Algorithm: Diagnosis and Treatment.

There has been a dramatic rise in the incidence of wounds in the United States. Chronic wounds are not only difficult and costly to treat, but also have a devastating impact on the patients, caregivers, and on society as a whole. Many factors influence the etiology of wounds. The goal of this article is to educate all types of healthcare providers on the evaluation process and the various available treatment options of chronic wounds. With the information presented in this article, providers will be able to achieve faster healing and hopefully decrease the total number of chronic and debilitating wounds.
