Evaluation of the effectiveness of maggot therapy and debridement on the healing of infected ulcers

Background and purpose: Infection is one of the main and dangerous complications of ulcer after surgery and diabetic foot and it is one of the main causes of limb amputation. Debridement of necrotic and infected tissues is very effective for ulcer preparation and ulcer healing process. One of the emerging techniques for debridement of infected tissue of wounds is the maggot therapy and with debridement of dead tissues and growth stimulation, it is very effective in reducing infection in the treatment process of these patients. The purpose of this research is to evaluation the clinical effectiveness of treating infected wounds with maggot therapy.Method: This study is a clinical trial on ۲۰ patients with infected ulcer (۱۵ patients with diabetic foot ulcers and ۵ patients with infected wounds after surgery) in the general and infection unit of Biseton Hospital. Lucilia sericata larvae were applied to the wounds for ۴۸-۷۲ hours (depending on the type of wound and infection) until the necrotic tissue was cleared during this period, the evaluation of the performance of the maggot effect was examined by the researcher and the changes in the percentage of the wound surface area and growing microorganisms were recorded.Results: The samples included ۲۰ patients who were hospitalized for ۱ to ۲ weeks and treated with maggot ۱ to ۲ times per week on average, out of ۱۵ diabetic foot ulcers, ۱۲ of them were completely healed and debrided and ۳ wounds reached the graft stage. ۵. Infectious wounds caused by infection after surgery were completely healed, and the microorganism isolated from the wound was significantly decreased immediately after the first maggot therapy.Conclusion: Although many methods are used in the treatment of infected wounds, the maggot therapy that is being used today is a simple and effective method in the treatment of infected wounds and its effect like biodebridement, asepsis, stimulating the growth and granulation of dead tissues, can help in the rapid healing of venous ulcers caused by diabetic foot ulcers and infections after surgery
