Objectives: An endeavor to look for cost effective method for dressing wounds to minimize loss of working hours. Three percent citric acid solution (CA) was used for dressing acute lower limb ulcers with the object of pH modulation of wounds at an early stage and to evaluate its effects on wound healing. This solution was compared with Edinburgh University solution of lime (Eusol) in a randomized double-blinded study. Appearance of healthy granulation was the end point of the study. Materials and Methods: An unicentric randomized double blinded study with a parallel design was used to compare patients treated with 3% CA and Eusol solutions, respectively. The results were analyzed using Chi-square and P value using Microsoft Excel and SPSS 22. Patients having fever, altered consciousness, high initial random blood sugar >350 mg%, positive urinary ketones, hypoproteinemia, signs of septicemia and vascular diseases were excluded. Results: Twenty patients were known diabetic out of which 11 were in the CA group, and the rest were in the Eusol group. It was observed that the average total stay in diabetic patients was 16.36 days in CA group and 31 days in Eusol group whereas it was 15.78 and 24.75 days respectively in the nondiabetic group. The ulcer granulation interval showed that the mean stay in CA group was 10.56 days while it was 20.04 days in the Eusol group. The cost of stay was less in CA group. Conclusions: It is concluded that 3% CA solution forms a good alternative for wound dressings that acts by modulating the wound pH to acidic levels thereby contributing to wound healing by increased fibroblast proliferation and probably increasing local oxygen concentration and reducing microbial growth and virulence.
