Chronic wounds caused by underlying physiological causes such as diabetic wounds, pressure ulcers, venous leg ulcers and infected wounds affect a significant portion of the population. In order to treat chronic wounds, a strong debridement, removal of necrotic tissue, elimination of infection and stimulation of granulation tissue are required. Maggot debridement therapy (MDT), which is an alternative treatment method based on history, has been used quite widely. MDT is an efficient, simple, cost-effective and reliable biosurgery method using mostly larvae of Lucilia sericata fly species. Larvae can both physically remove necrotic tissue from the wound site and stimulate wound healing by activating molecular processes in the wound area through the enzymes they secrete. The larvae can stimulate wound healing by activating molecular processes in the wound area through enzymes in their excretions/secretions (ES). Studies have shown that ES has antibacterial, antifungal, anti-inflammatory, angiogenic, proliferative, hemostatic and tissue-regenerating effects both in vivo and in vitro. It is suggested that these effects stimulate wound healing and accelerate wound healing … read more

Protecting Periwound Skin in Chronic Wounds
The periwound is as important as the wound. As clinicians, we should carefully assess the wound bed, but we need to remember also to assess the periwound and surrounding skin. The periwound should be considered the 4cm of surrounding skin extending from the wound bed. Chronic wounds may manifest any of the following characteristics, depending on wound type: erythema, induration, epibole, ecchymosis, hyperkeratosis, and changes in shape.
Five-Step Periwound Assessment
- Temperature
- Location
- Shape
- Color
- Wound depth
The temperature of the periwound can be a good indicator of whether active infection is present or to determine whether there is normal blood flow. The back of the hand is most accurate … read more
