Text Box: Healing the Chronic Wounds The most common areas on the body where pressure sores develop are the sacrum (buttocks), ischium (hip area), trochanters (the upper thigh), and around the ankles and heels. They occur primarily due to extended periods of immobility or irritant chafing of the skin. The process of healing a wound is a dynamic repair method. It consists of three defined phases 1) inflammatory, 2) proliferation and 3) maturation. To progress normally, each phase consists of a unique cellular interaction. There has been much progress in the treatment of pressure ulcers. According to Dr. Kath Bogie, a prominent researcher in this area, “as multidisciplinary research and care increases, so, too, will the evidence base required to address these common and complex, chronic wounds.” Progress has been made in dressings, creams, gels and technology. One prevalent area of technology is the use of electrical stimulation. Alternative therapies such as ultrasound, ultraviolet light, superficial heating, pulsed electromagnetic fields, and electrical stimulation have all been studied in the treatment of chronic wounds. Let’s focus on the last treatment mentioned, electrical stimulation. Over the past decade, much research has been conducted in the use of electrical stimulation to treat pressure ulcers. Research published by Luther Kloth of Marquette University explains the basis of using electrical stimulation for the treatment of chronic wounds. “The treatment goal for electrical stimulation is to attract negatively or positively charged cells into the wound area, such as neutrophins, macrophages, epidermal cells and fibroblasts that in turn will contribute to wound healing processes by way of their individual cellular activities.”1 The application of electrical stimulation for wound healing has been found to significantly increase the healing rate and be effective in a large number of cases. Several studies seek to prove the effectiveness and safety of electrical stimulation in the treatment of chronic wounds. In essence, external stimulation may serve to mimic the failed natural bioelectric currents which allow wound healing to proceed. It has also been proven that given daily, electrical stimulation is effective for enhanced healing rates. However, the success of electrical stimulation is not for every wound. It is dependent to diagnosis, depth of lesion, and severity of infection. As a treatment option electrical stimulation is easy to apply and can be used by a person at home following instruction from a medical doctor or therapist experienced with electrical stimulation and the treatment of pressure ulcers. To consider this treatment, discuss it with a medical professional prior to beginning any treatment. In addition, practical issues such as cost, time, required training, and patient and therapist safety concerns need to be discussed and addressed. Local or regional insurance coverage may be available however nationally the Center for Medicare and Medicaid does not cover electrical stimulation for wound healing. As of this writing, we have not been able to find many devices yet approved by the FDA specifically for wound healing, although several devices approved for other indications are being applied for this purpose via off-label use. One device (the Staodyn Dermapulse) has undergone controlled animal and human testing, and an application requesting approval for treating dermal ulcers has been submitted to FDA. There is also an “electric bandage” offered by Biofiscia; however, it is only available for commercial use in Europe and Canada. With this in mind, there are several clinical trials and devices in development supported by the many years of research. 1 Kloth L.C.

Wounds that can take you out
Text Box: A scratch on your finger and a scrap on your knee are “every day” wounds. This issue we are focusing not on the “every day” wound but the deep tissue wounds that afflict thousands of people. These deep tissue wounds are also known as pressure ulcers, decubitus ulcers, bed sores or pressure sores. They develop primarily from pressure in a concentrated area of the skin or from shearing of the skin. These wounds surface in hospitals, nursing homes and among people with disabilities in the community. Persons with paralysis, users of prosthetic limbs, people with peripheral nerve disorders, those living with diabetes and the elderly are at high risk of developing pressure sores. In a study published in 1998 by Dr. Gilcreast, et al, it is estimated that the failure of foot wounds to heal results in 54,000 people with diabetes having to undergo extremity amputations annually in the U.S. A pressure sore can take a person out of his/her daily life for six months to a year and cost an estimated $100,000 in health care. The prevalence of pressure sores in hospital patients is high and even higher for those in nursing homes. So what part can technologies play in this? There are two areas that we will cover in this issue, the role of neurotechnology in the area of healing a wound and the role of prevention.
