Abstract
Diabetic foot infections are the major cause of morbidity. Infection is the common sequel of diabetic foot ulceration that leads to delayed wound healing. These infections are difficult to control. If not addressed well in time, they may lead to amputation of foot. An attempt has been made to develop simple and effective treatment modality by using citric acid as a sole antimicrobial agent to control diabetic foot infections not responding to conventional treatment. Hundred and fifteen cases of diabetic foot ulcers of different Wagner grades infected with a variety of bacteria were investigated for culture and susceptibility, and susceptibility to citric acid. Citric acid gel was applied to ulcer to determine its efficacy in the management of diabetic foot ulcers with different Wagner grades. Citric acid gel was found effective in the control of foot infections; especially in Wagner grades I and II, the success rate was found to be more than 94%. In Wagner grade III also, it was found effective in complete healing of ulcers without deep osteomyelitis. Citric acid treatment is effective in the control of diabetic foot infections and in successful management of diabetic foot ulcers with Wagner grades I and II, and even with Wagner grade III, without deep osteomyelitis.
