Low-temperature hydrogen peroxide gas plasma sterilizers utilized in medical institutions of Yangpu District, Shanghai

ObjectiveTo investigate the use of low-temperature hydrogen peroxide gas plasma sterilizers in medical institutions in Yangpu District of Shanghai, and to find out the weaknesses in time, proposing measures to improve the quality of sterilization.

MethodsOn-site interviews were made with department chiefs and inquiries on their relevant records; and with these, lumen bio-PCD (process challenge device) was used to test the sterilization effect.

ResultsThere were 17 low-temperature hydrogen peroxide gas plasma sterilizers equipped in 8 medical institutions in the district.Each unit could operate the sterilizer correctly according to the instructions and operation process of the sterilizer.All the sterilizers were biologically monitored by lumen bio-PCD (process challenge device), and the sterilization effects were all qualified.But there were still some problems in cleaning, drying and monitoring.

ConclusionAs a new sterilization technology, low-temperature hydrogen peroxide gas plasma sterilization technology needs the joint efforts of all parties to improve the product, technology, system, process, etc., updating the quality of sterilization.
