    Effectiveness of ethylene oxide in the sterilization process of polymer materials
    (Universidad Privada Norbert Wiener, 2018-08-04) Fuentes Vasquez, Irma de Guadalupe; Tejerina Vegazo, Dany Marcell; Gamarra Bustillos, Carlos
    The data search examined the effectiveness of ethylene oxide in polymeric materials. According to the results obtained from the systematic review, they show that, of the total of 10 articles reviewed, 30% (3) of these correspond to the United States, 30% (3) correspond to Brazil, 10% (1) correspond to Cuba , 10% (1) corresponds to Guatemala, 10% (1) to Venezuela and 10% (1) to Argentina. Conclusions: The systematic review of the 10 scientific articles on the effectiveness of ethylene oxide in polymer material, all of them correspond to the type and design of experimental studies - clinical trial. It was evident in the research reviewed that there is greater effectiveness of ethylene oxide in polymer material due to its great effectiveness; perfect for thermosensitive materials since sterilization is done at low temperature, which guarantees non-deformation and non-destruction of the elements; excellent diffusion coefficient in packaging, in places of difficult accessibility and penetration into folds; and the process does not alter the physical qualities of the sterilized product.

    Effectiveness of ethylene oxide sterilization method in thermosensitive medical devices
    (Universidad Privada Norbert Wiener, 2017-11-12) Quiroz Torres, Lucy Marlene; Quispe Alcas, Rocío; Calsin Pacompia, Wilmer
    Objectives: To systematize the evidence on the effectiveness of the ethylene oxide sterilization method for heat-sensitive medical devices. Materials and Methods: This is a systematic review of articles found in PubMed, Lilacs, Medline, Elsevier, and WorldWideScience, which underwent critical reading and were analyzed using the GRADE system to identify their level of evidence. According to the results obtained from the systematic review, of the total 10 articles reviewed, 50% (5) are from Brazil, 20% (2) are from the USA, 10% (1) is from Cuba, 10% (1) is from Japan, and 10% (1) is from Portugal. In terms of research study type, 60% (6) are experimental studies, 10% (1) is a systematic review, 10% (1) is a clinical experimental study, and 20% (2) are literature reviews. Results: 100% of the articles indicate that ethylene oxide is an effective sterilizing agent for heat-sensitive medical devices and materials. Conclusions: Of the 10 articles reviewed, 100% (n=10/10) show that the ethylene oxide sterilization method is effective for heat-sensitive medical devices due to its bactericidal, virucidal, fungicidal, and sporicidal properties, as well as its high penetrability and compatibility with most materials.
