Corrosion of surgical instruments due to the use of common water vs distilled water
(Universidad Privada Norbert Wiener, 1905-07-09) Castillo Sánchez, Rosa María; Gómez Gonzales, Walter Edgar
Objective: Determine if the corrosion of surgical instruments is produced by the use of common water vs. distilled water. Materials and Methods: Systematic Reviews are an observational and retrospective research design, which synthesizes the results of multiple primary investigations. They are an essential part of evidence-based nursing due to their rigorous methodology, identifying relevant studies to answer specific questions of clinical practice. Results: In the final selection, 13 articles were chosen, we found that 31% (4) correspond to Spain, 14% (2) correspond to Colombia and Chile, with 7% (1) Cuba, Mexico, Peru were found. , Venezuela and Brazil respectively. 69% were experimental studies from the countries of Spain, Peru, Mexico, Colombia, Venezuela and Chile. With 31% we have cross-sectional studies belonging to Brazil, Chile, Spain, and Cuba. Of the total number of articles analyzed, 80% concluded that plain water causes corrosion in surgical instruments. It was evident in the reviewed research that stainless steel instruments should not be subjected to cleaning, disinfection and sterilization processes, whose dilution component is common water, nor should they be immersed in a physiological salt solution. Prolonged contact and immersion in the solution causes corrosion pitting and forms stress corrosion cracking. Conclusion: It is recommended to use distilled water to avoid corrosion of surgical instruments, especially for final rinsing, after cleaning and disinfection.

Efficacy of glycine versus distilled water to reduce hydroelectrolyte disorders in patients undergoing transurethral resection
(Universidad Privada Norbert Wiener, 2017-08-05) Lugarte Caballero, Giner Valentin; Revatta Beingolea, Hilda; Rivera Lozada de Bonilla, Oriana
The objective of the research is to systematize the evidence on the effectiveness of glycine versus distilled water to reduce hydroelectrolyte disorders in patients undergoing transurethral resection (TUR). 10 scientific articles were reviewed, including controlled, randomized, cohort, case-control, and experimental trials. 50% evidence was found that irrigated patients present hyponatremia, being less with distilled water, 10% evidence that the use of distilled water reduces perioperative hypothermia and tremors, 10% demonstrates in a comparison of the absorption of irrigation fluids (saline solution ) used during rtu, is a non-significant percentage. 10% conclude that glycine solution increases the transparency of the optics, compared to distilled water, 10% demonstrate that irrigation with water in preventing the recurrence of non-muscle invasive bladder cancer is as effective as mitomycin, 10 % conclude that distilled water is an effective solution as an irrigant in procedures such as percutaneous nephrolithotomy. Concluding that both distilled water and glycine produce hydroelectrolyte disorders when used as irrigant in rtu, where the differences are not statistically significant.

Estudio comparativo de la morfología celular en el método de tinción Wright con agua tamponada, agua destilada, agua purificada y agua de grifería, Perú 2024
(Universidad Privada Norbert Wiener, 2025-03-19) Castillo Borja, Natalia Milagros; Huamán Cárdenas, Víctor Raúl
La presente investigación tuvo como objetivo comparar la calidad de la morfología celular en la tinción Wright utilizando diferentes tipos de agua en el proceso de tinción: agua tamponada, agua destilada, agua purificada y agua de grifería en Perú, 2024. Para ello, se empleó un enfoque cuantitativo con un diseño experimental. La muestra estuvo conformada por 316 láminas preparadas con los cuatro tipos de agua mencionados, las cuales fueron analizadas microscópicamente para evaluar posibles alteraciones en la morfología celular y la calidad de la tinción. Los resultados indicaron que la tinción Wright con agua destilada permitió una mejor conservación de la estructura celular, mostrando menor alteración en la morfología y una coloración más nítida. El agua purificada obtuvo resultados intermedios, mientras que el agua tamponada presentó ligeras irregularidades en la forma celular. En contraste, el agua de grifería generó mayores distorsiones y defectos, afectando la calidad de la tinción y la observación de los componentes celulares. Se concluyó que el tipo de agua utilizado en la tinción Wright influye significativamente en la calidad de la morfología celular, siendo el agua destilada la mejor opción para garantizar una tinción óptima en el análisis hematológico. Estos hallazgos pueden servir como referencia para mejorar las prácticas en laboratorios con recursos limitados, donde el acceso a agua tamponada podría ser restringido. Palabras clave: tinción Wright, morfología celular, hematología, agua tamponada, agua destilada, laboratorio clínico.
