Despite this, there are a few studies describing the application of ozone as a sterilizing agent of medical devices. The aim of this communication was to describe the development and validation of a sterilization cycle applied to medical devices. Methods: The sterilization process was challenged using Geobacillus stearothermophilus ATCC 7953 spores, which have shown great resistance. The sterilizing effect of ozone was measured using carriers inoculated with 10⁶CFU/mL spores, introduced into a 3-mL syringe and lumens of tubes of different sizes and diameters simulating hospital medical products, which have undergone a half-cycle or complete cycle. Results: The results of sterilization process studied in active vegetative form of microorganisms showed that the ozone sterilization was effective with a bioburden between 10⁵ to 10⁷ CFU/mL with one pulse sterilizing action. The validation of the process was confirmed by the satisfactory results for the half-cycle, corresponding to a treatment with four pulses allowed sterilizing the material with bioburdens < 10⁶CFU/mL spores which indicate an appropriate sterility assurance level. Conclusion: The results showed that the ozone may be considered as effective and promising alternative for sterilization of thermosensitive materials and medical devices.]]> Mon 10 Apr 2023 10:21:35 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:39308 Fri 03 Jun 2022 15:00:35 AEST ]]>
