    Effectiveness of pulsed xenon ultraviolet light to reduce the contamination of pathogenic microorganisms in the hospital environment.
    (Universidad Privada Norbert Wiener, 2021-04-04) Rojas Chamorro, Noelia del Carmen; Mori Castro, Jaime Alberto
    Material and Methods: It is a retrospective and observational systematic review subject to critical reading and using the GRADE system as an evaluation tool for recognizing the quality of scientific evidence published in the following information sources: Epistemonikos, PubMed, Elsevier, Sciencedirect, and Researchgate. Among the 10 systematically reviewed articles, 20% are of high quality, and 80% are of moderate quality as follows: 20% (n=2/10) are meta-analyses, and 80% (n=8/10) are cohort studies and belong to the United States (70%), China (20%), and the United Kingdom (10%). Results: 100% (n=10/10) indicate that pulsed xenon ultraviolet light is effective in reducing infection from multidrug-resistant organisms in the hospital setting. Conclusion: In 10 out of 10 articles, it is evidenced that pulsed xenon ultraviolet light is effective in reducing infection from multidrug-resistant organisms in the hospital setting.

    Laminar airflow ventilation is effective in reducing infections in patients undergoing surgery
    (Universidad Privada Norbert Wiener, 2019-06-30) Lázaro Saldaña, Monica; Matta Solis, Hernán Hugo
    Objective: To systematically analyze the evidence on the effectiveness of laminar airflow ventilation in reducing infections in patients undergoing surgery. Material and methods: The systematic review of the 10 scientific articles evidenced on the effectiveness of laminar air flow ventilation to reduce infections in patients undergoing surgery, were obtained from the following databases Epistemonikos, Pubmed, Scielo, Medline, Ebsco, Dialnet, ProQuest and Google scholar. They were analyzed according to the Grade scale to determine the strength and quality of the evidence. Of the 10 articles, 60% (6/10) correspond to the methodological design of a systematic review, 30% (3/10) are a cohort study and 10% (1/10) are quasi-experimental studies. RESULTS: Of the 10 articles reviewed, 40% (4/10) demonstrate that laminar airflow ventilation is effective in reducing infections in patients undergoing surgery, since they improve the reduction of infections in patients undergoing surgery. surgery, 60% (6/10) showed that there is no decrease in infections in patients undergoing surgery. CONCLUSIONS: The present systematic review concludes that 6 of 10 evidence demonstrate that laminar airflow ventilation is not effective in reducing infection in patients undergoing surgery; and 4 out of 10 evidence indicates that it is efficient.
