당뇨병발 궤양의 치료. (Korean)

Background: Diabetic foot ulcers (DFUs), a risk factor for infection, remain a difficult clinical complication. Infected DFUs may be associated with lower extremity amputation. To achieve wound healing and avoid amputation, an assortment of dressing materials and negative pressure wound therapy (NPWT) have been used on soft tissue injuries resulting from infected DFUs. A great deal of interest about the use of dressing materials and NPWT in the treatment of DFUs has arisen. However, there have only been a few high-quality studies regarding this topic. Current Concepts: Ideal dressing materials should satisfy certain conditions to alleviate symptoms of DFU infection and enhance the wound healing process. A single dressing material cannot fulfill all of these requirements. Based on clinical trials, different dressing materials must be chosen according to the status of the individual wound environment, including the amount of exudate, degree of pain, severity of the infection, and cost-effectiveness. However, there has been no clear evidence that advanced wound dressing materials are superior to basic dressing materials in wound healing. Recently, NPWT has been used to cover the soft tissue defects of infected DFU with granulation tissue. NPWT may contribute to changing growth factor expression, micro- and macro-deformation, vascular flow, amount of exudate, and the bacterial environment in DFU, despite the unclear mechanism of its role in wound repair. Discussion and Conclusion: Further research to obtain high-quality evidence regarding the benefits of using dressing materials and NPWT is needed. The optimal protocol for DFU and cost-effectiveness should be included in these future studies. [ABSTRACT FROM AUTHOR]
