Aerosols are defined as the mixture of liquid or solid particles/droplets that are stably suspending in air. When carrying a certain amount of negative charge, they will be defined as negatively-charged aerosol. This report investigates the effect of negatively-charged aerosol on the healing of chronic wound. 140 patients with chronic wound were assigned randomly into two groups. Normal, routine treatment was applied on chronic wounds of 73 patients depending on wounds situation (control group). While another 67 similar patients received negatively-charged aerosol therapy (2 hours per time, twice a day) and were used as experimental group. Wound healing assessment including the patients' complication, detection of bacteria in wound secretions, and evaluation of wound healing. The results of our study showed that after the application of negatively-charged aerosols, and condition and infection rate of wounds from experiment group were better and lower than that of control group. In comparison with control group, the relative size of wounds from experiment group was significantly smaller (P<0.05) at post-treatment day 0, 7, 14, 21 and 28. Also, the time required for wound healing in the experimental group was significantly shorter (P<0.05) than that in the control group. Negatively-charged aerosol therapy can accelerate wound healing speed and improve the healing of chronic wounds. Thus, we wound recommend the consideration of Negatively-charged aerosol therapies in addition to normal wound treatment in cases of chronic wound.
