    Determination of the safe disinfectant Orthophthaldehyde versus Glutaraldehyde used by nurses in the High Level Disinfection Process
    (Universidad Privada Norbert Wiener, 1905-07-09) Idrogo Maita, Zaida Karina; Ruiz Campos, Deysi; Gómez Gonzales, Walter Edgar
    Objectives: Determine the safe disinfectant Orthophthaldehyde vs glutaraldehyde to be used by nurses in the high-level disinfection process. Materials and Methods: Observational and retrospective systematic review, the search has been restricted to 8 articles with full text, and the selected articles were subjected to critical reading. Published and indexed in scientific databases, dating back to the year 2000 and responding to articles published in Spanish, English and Portuguese. In the final selection, 4 articles were chosen, we found that 25% (01) corresponds to England, with 25% (01) to Spain, with 25% (01) to Brazil and while another 25% (01) we find Japan; Two systematic reviews and two cross-sectional studies were included. Results: 80% of the articles reviewed show that glutaraldehyde, compared to orthophthaldehyde, is the one that produces the most cytotoxicity at work, but that orthophthalaldehyde is still toxic. Orthophthaldehyde vs glutaraldehyde, in both cases its greatest adverse reaction when used is in the respiratory tract Conclusion: of the liquid chemical substances used as high-level disinfectants Orthophthaldehyde vs Glutaraldehyde It was evident that Glutaraldehyde is a volatile product that emanates cytotoxic substances causing effects adverse effects on the person who handles it, while Orthophthaldehyde, being exposed through inhalation, turns out to be a sensitizing this. The direct handling of high-level disinfectant substances focuses exposure on the inhalation route, requiring the use of personal protective equipment.

    Effects on health from exposure to surgical smoke of operating room personnel
    (Universidad Privada Norbert Wiener, 2019-02-17) Castillo Baca, Fanny Mary; Aponte Jara, Yesenia Iris; Gamarra Bustillos, Carlos
    Surgical smoke contains substances that are harmful to healthcare personnel, as 80% consists of water vapor and 20% includes substances such as formaldehyde (irritant and potential carcinogen), acetaldehyde (carcinogen), benzene (carcinogen), and toluene (respiratory and eye irritant as well as neurotoxic when inhaled). Additionally, hydrogen cyanide (3-51 parts per million), acetylene (2-8 parts per million), and 1,3-butadiene (0.15-0.69 parts per million) were identified in the plume. These chemical compounds can trigger harmful effects on the human body, including cancer and respiratory symptoms such as pharyngeal burning, nasal congestion, nausea, and headaches. Therefore, exposure to and inhalation of this smoke affects the health of operating room personnel, depending on the duration of exposure and the type of surgery performed, leading to long-term consequences.

    Evaluación del isopropanol como agente aclarante alternativo al xileno en el procesamiento histotecnológico del laboratorio de anatomía patológica del Hospital San Bartolomé, agosto – noviembre 2023
    (Universidad Privada Norbert Wiener, 2025-12-03) Enciso Fanola, Chuver Adelio; Ascarza Gallegos, Justo Ángelo
    Objetivo: Evaluar si el isopropanol es un agente aclarante alternativo al xileno en el procesamiento histotecnológico del laboratorio de anatomía patológica del Hospital San Bartolomé en el período de agosto – noviembre 2023. Metodología: estudio de enfoque cuantitativo, aplicado, experimental y de diseño cuasi – experimental. La muestra estuvo conformada por una muestra representativa de 25 unidades de isopropanol y por duplicado con el agente desparafínate estándar (xilol) lo que permitió comparar. Para el análisis se estimó el índice de Kappa y para comparar las proporciones de dos grupos independiente se utilizó la prueba no paramétrica U de Mann-Whitney. Resultados: El isopropanol es un posible agente aclarante alternativo al xileno en las características macroscópicas (sig.: 0.000), en el seccionamiento (sig.: 0.000), en la calidad de la coloración (sig.: 0.000) de los tejidos del laboratorio de anatomía patológica del Hospital San Bartolomé. Al final se concluye: el isopropanol es un posible agente aclarante alternativo al xileno en el procesamiento histotecnológico (sig.: 0.000) del laboratorio de anatomía patológica del Hospital San Bartolomé en el período de agosto – noviembre 2023
