ABSTRACT
INTRODUCTION:
Ozone is a potent antibacterial agent. Because ozone oxidizes organic material, it directly attacks microorganisms resulting in safe, fast and economical sterilization at low temperatures. This study evaluated the efficacy of ozonated water in the reprocessing of dialyzers obtained from a hemodialysis service in São José do Rio Preto.METHODS:
A total of 23 blood dialyzers were collected at the conclusion of the morning hemodialysis shift. The equipment was collected after the maximum number of reuses, with the last disinfection performed with purified water (obtained by reverse osmosis and subsequent reverse ultrafiltration). The number and species of microorganisms in the dialyzers were evaluated before and after treatment with ozonated water. The ozonation of sterile deionized water was achieved by direct contact between the water and the ozone generating equipment.RESULTS:
The mean number of microorganisms before sterilization was 1,47.10(9) colony forming units per ml (CFU/ml). After treatment with ozonated water, the number of microorganisms was 4,80.10¹ CFU/ml.CONCLUSION:
Ozonated water is an effective decontaminant for most blood dialyzers.
