In the July 2018 publication on PubMed titled "Hydrogen peroxide plasma sterilization of a waterproof, high-definition video camera case for intraoperative imaging in veterinary surgery," researchers explore the efficacy of hydrogen peroxide plasma sterilization for a specialized video camera case used during surgeries on animals.
The study focuses on this specific waterproof, high-definition video camera case designed for intraoperative imaging, a device category crucial for enhancing visibility and accuracy in veterinary surgery. The researchers test the effectiveness of hydrogen peroxide plasma sterilization, a sterilization method gaining attention due to its potential to reduce contamination risks during surgical procedures.
The researchers conduct a series of experiments at an unspecified veterinary hospital's CSSD (central sterile supply department). Using cycle times and temperatures specified by the International Organization for Standardization (ISO) and Association for the Advancement of Medical Instrumentation (AAMI), they subject the camera case to multiple rounds of hydrogen peroxide plasma sterilization.
The results indicate that the hydrogen peroxide plasma sterilization method achieves a 6-log reduction in bacteria, surpassing the required pass/fail criteria for device sterilization as outlined by both ISO and AAMI standards. The study successfully demonstrates that this method can effectively sterilize the waterproof, high-definition video camera case, ensuring its safe use during veterinary surgeries.
The researchers also test the water resistance of the camera case before and after sterilization using a 30-minute submersion in distilled water at room temperature. The tests show no water ingress into the device following sterilization, indicating that the waterproof properties of the camera case remain intact post-sterilization.
