Adverse Events with Low Temperature Hydrogen Peroxide Gas Plasma Sterilisation Reported by Certified Sterilisation Service Technicians and Certified Sterilisation Specialists In Japan

摘要

Background: The incidence of hydrogen peroxide vapour (HPV) in the proximity of low temperature hydrogen peroxide gas piasma (LTHPGP) sterilisers and residual HPV on and in packs of surgical devices sterilised with LTHPGP was found in a series of studies to be higher than expected.Objective: To evaluate adverse events associated with HPV in clinical settings. Methods: A. questionnaire on the adverse events associated with HPV was sent to certified sterilisation service technicians (CSST) and certified sterilisation specialists (CSS), of the Japanese Society of Medical Instrumentation. Results: Among 774 replies, 472 facilities employed LTHPGP sterilisers. Of 472 facilities,136 (28.8%) had experienced adverse events caused by LTHPGP sterilisation. Conclusion: In order to utilize HP sterilisation effectively, the safety of HPV should be carefully considered for patients and personnel engaged in central services.
