The study revealed that ozone gas and oil groups were able to completely eliminate multidrug-resistant bacteria within 30 minutes, while the bactericidal effect of the ozone gas group was significantly better than the ozone water and oil groups at 5 and 10 minutes. There was no significant difference in bactericidal effect between the ozone water group and the ozone gas and oil groups after 30 minutes.
Objective: To examine the bactericidal effects of three different states of medical ozone (liquid, gas, and oil) against drug-resistant strains of common bacteria on burn wounds, which could as a clinical reference. Methods: Three multidrug-resistant strains of methicillin-resistant Staphylococcus aureus, pan-resistant Pseudomonas aeruginosa, and ESBLs Klebsiella pneumoniae were identified from burn wounds. The colonies of the three varieties of bacteria were each carried out using the pour plate method prior to the start of the experiment. Then, depending on the state of ozone, different treatment procedures are applied. Group of ozone gas: in a closed glass jar, the bacterial liquid was injected into a single layer of sterile gauze, and the ozone gas concentration was held at 50 g/mL. The bacterial liquid was diluted and combined directly with ozone water in the ozone water group. Ozone is a type of oil: after the emulsifier was added to the oil group. The gas, water, and oil groups were rapidly neutralized and counted again after 5, 10, and 30 minutes. Results: Ozone gas and oil groups totally eliminated multidrug resistant bacteria in the above study within 30 minutes. (2) At 5 and 10 minutes, the difference in bactericidal effect between ozone gas group and ozone water and oil group was statistically significant (P 0.05), and there was no significant difference between ozone water and oil groups (P 0.05); at the time of 30 minutes, the effects of bactericidal effect between ozone water group and ozone gas and oil had no significance (P> 0.05). Conclusion: Ozone has the ability to kill bacteria, depending on the treatment time, different ozone types should be chosen for sterilization and disinfection in clinical application.
