Abstract
Objective: To analyze the effectiveness of ozonized water in the disinfection of orthopedic surgical table surfaces in a public hospital in the Baixo Amazonas region. Methods: Exploratory-descriptive study, carried out in Santarém, Pará, with surgical table surfaces for sampling. Surfaces were analyzed after disinfection with ozonized water using the Adenosine Triphosphate Bioluminescence (ATP) assay, considered effective when the recording was less than 250 Relative Light Units (RLUs). Data were analyzed using the IBM SPSS Statistics software and using the chi-square test. The study was approved by the Research Ethics Committee (CEP) under the number of CAAE 39785220.4.0000.5168. Results: The sampling comprised 24 surfaces of surgical tables disinfected with ozonized water. Values of up to 10 RLU accounted for the largest number of records, with 83.3% (20), while values of 11-20 RLU had 12.5% (3), and 21-30 RLU indicated 4.2% (1). The method used to assess disinfection did not show contamination in 100% of the surfaces analyzed. Conclusion: The values of RLUs obtained from the ATP bioluminescence assay showed that the use of ozonized water on surfaces of orthopedic operating rooms is an effective proposal for disinfection in a nosocomial environment.
