Sterilization is of prime importance especially in the field of medical devices (MDs), where a lot of products need to be sterilized before being put on the market to prevent patient exposure to infections. Therefore, it is important that the MDs company's sterilization process complies with current guidelines and that a robust quality system ensures that the sterilization cycle meets the prevalidated specifications. ?? My internship in LivaNova consisted in analyzing the ethylene oxide (ETO) sterilization process currently in use at Mirandola Plant. Particularly, during the first months, I familiarized with the regulations of reference, the internal procedures and the three main software programs used for management and monitoring of the sterilization plant.
