Effectiveness of alternative disinfectants: peracetic acid and ortho-phthalaldehyde compared to glutaraldehyde for achieving optimal and damage-free disinfection in flexible endoscopes
(Universidad Privada Norbert Wiener, 2018-08-25) Alvarez Avalos, Hiozime; Matta Solis, Hernán Hugo
Objective: To systematically analyze the evidence on the effectiveness of alternative disinfectants: peracetic acid and ortho-phthalaldehyde compared to glutaraldehyde for achieving optimal and damage-free disinfection of flexible endoscopes. Materials and Methods: Systematic review of 06 articles from international studies and research, including the most relevant ones according to the level of evidence, restricted to full-text articles. Of the 06 articles reviewed systematically, 50% are systematic reviews, 33% are controlled clinical trials, and 16% are experimental studies. The articles underwent critical reading using the GRADE scale. Results: Of the 60% of reviewed articles, 20% demonstrate that the disinfectants studied are effective in inactivating vegetative microorganisms under the established conditions of use, 20% of the articles demonstrate that preconditions are important for ensuring proper disinfection, and 30% of articles indicate that the use of ortho-phthalaldehyde, like glutaraldehyde and peracetic acid, has been cited in relation to its toxicity, making it unsafe as an alternative. No studies were found reporting damage to endoscopes caused by the disinfectants. Conclusions: Of the 06 articles reviewed, it is evident that the disinfectants peracetic acid and ortho-phthalaldehyde are effective in inactivating microorganisms. Preconditions must exist to ensure proper disinfection. The disinfectants have been cited for their toxicity, and no studies report damage to endoscopes.

Effectiveness of high-level disinfection as a safe reprocessing method for endoscopes
(Universidad Privada Norbert Wiener, 1905-07-09) Soto Espinoza, Miriam Giovanna; Aranguren Hernandez, Nacy Melania; Gómez Gonzales, Walter Edgar
Objective: Determine the effectiveness of high-level disinfection as a safe reprocessing method for endoscopes. Materials and Methods: A systematic review was carried out, which synthesizes the results of multiple primary investigations. They are an essential part of evidence-based medicine due to their rigorous methodology, identifying relevant studies to answer specific questions of clinical practice. Results: The systematic review of the 06 scientific articles on the effectiveness of high-level disinfection as a safe reprocessing method for endoscopes correspond to the Lipecs, Lilacs, Scielo and Medline databases. The DAN in an endoscope after having been used when there are traces of organic secretions is not sufficient. Conclusion: Every endoscope, after having been used, when there are organic secretions, must be sterilized after high-level disinfection has been carried out.

Effectiveness of high-level disinfection in flexible endoscopes for the prevention of infections
(Universidad Privada Norbert Wiener, 2021-08-29) Quintana Garcia, Susan Estefanie; Zurita Mendoza, Richard Alfredo; Mori Castro, Jaime Alberto
Objective: Determine the effectiveness of high-level disinfection in flexible endoscopes for the prevention of infections. Methodology: The work is a systematic review consisting of 10 published and indexed scientific articles, data collection was carried out through Pubmed, Sciencedirect, Redalyc, Cochrane, Researchgate, the analysis was developed using a summary table which evaluates the quality of the evidence and strength of recommendation of each scientific article chosen according to the established technical criteria and guaranteeing compliance with ethical principles. Conclusion: The systematic review shows that high-level disinfection is not enough to avoid infections caused by the use of reprocessed flexible endoscopes, and it is also concluded that cleaning is the most important step in this process and the most difficult in correct compliance.

Efficacy of high-level disinfection in safe disinfection of endoscopes
(Universidad Privada Norbert Wiener, 1905-07-09) Rubio Ampuero, Rosa Elena; Gómez Gonzales, Walter Edgar
Objective: Determine the effectiveness of High Level Disinfection (HLD) in the safe disinfection of endoscopes. Methodology: Systematic review whose population is made up of 06 published and indexed scientific articles, data collection was carried out through Lilacs, Scielo, Cochrane Plus, Medline, the analysis was carried out through a summary table, evaluating the quality of evidence and strength of recommendation in a critical and intensive manner for each article according to the established technical criteria, guaranteeing compliance with ethical principles. Results: At the national level, the Herediana Medical Journal concludes that the bacterial load before the cleaning and disinfection process of 50 endoscopes was positive in 88% and after the process positive in 26%. At the international level, the Chilean Journal of Infectology refers to infections exogenous pneumonias such as post-bronchoscopy pneumonia, which reach incidence rates, according to the authors, between 0.6% and 6.9% of the procedures.(6).The Spanish Society of Gastroenterology refers in 02 studies that DAN is not sufficient, both for endoscopes and accessories. The predominant bacteria in the positive cultures were Pseudomona Aeruginosa and Klebsiella Pneumoniae. Conclusion: The systematic review shows that DAN is not sufficient for the safe disinfection of endoscopes in sterilization centers.
