About

One of the common complications of diabetes mellitus (DM) is Diabetic Foot Ulcer (DFU), which can subsequently lead to infections, gangrene, amputation or even death, if necessary care is not taken to curb with the condition. Despite the rapid advancements in the medical industry, diabetic foot ulcer (DFU) is considered as a major factor of morbidity and a leading cause of hospitalizations among diabetic patients. The risk of ulcer progression that may ultimately lead to amputation is elevated upon the development of DFU. It is estimated that DFU contributes approximately 50-70% of all lower limb amputations. In addition to rendering emotional and physical distress, DFU is also responsible for causing productivity and financial losses that lower the quality of life. The economic burden of the patients is further aggravated by the medical expenditure involved in the healing of DFU and/or lower extremity amputation. This study focuses on usage of a modern primary wound dressing in managing diabetic foot ulcer. The primary dressing used in this study is an activated carbon cloth dressing, which is applied directly to the wound bed and the "holes" in the net give access to the activated carbon which is made up of millions of micropores and within the walls of these micro pores, there is presence of electrostatic forces known as Van der Waals forces, which helps to trap and kill microorganisms such as MRSA and Pseudomonas aeruginosa. In addition, the dressings can regulate matrix metalloproteinases (MMPs) which are responsible for prolonged inflammation in chronic wounds like diabetic foot ulcers, and able to promote fibroblast migration and accelerate granulation tissue growth via its conductivity.
