To evaluate the effects of ozone so lution on the healing and antiinfection of traumatic wound. Methods :300 patients with traumatic wounds were washed with ozone solution. Under the direction of ozone generator handbook, the ozone solution of which con centration was not less than 6 mg·L-1was prepared. The solution was used for the traumatic wound by atomized or beam spraying. The healing conditions of the wounds were observed and recorded the 3,5,7 days after debridement. Results:In the experimental group, there were 142 cases (87.6% ) with first grade intention, 16 cases (9.9%) with second grade intention, and 4 cases (2.5%) with the third grade intention. On the contrast, there were 76.8%, 17.3% and 5.8%, respectively, in the controlled group. There was avery signific anty difference between both experimental groups (P＜0.05).Concl usion: Ozone solution is a safe, cheap, high efficient disinfectant agent, used widely in the traumatic surgery and other fields for disinfection or sterilization.
