(Universidad Privada Norbert Wiener, 2018-08-12) Quiñonez Rodriguez, Mayra Daniela; Pinedo Flores, Milagros Gretel; Calsin Pacompia, Wilmer
Objective: Analyze and systematize the evidence on the effectiveness of ultrasound in the placement of catheters for hemodialysis in patients with chronic renal failure. Materials and Methods: The type and design of the study was quantitative and systematic review respectively, 10 scientific articles made up the population and sample, of 100%, 40% correspond to Spain, 10% correspond to the United Kingdom, 10% Uruguay, 10 % Paraguay, 10% USA, 10% Mexico and 10% Iran. 70% corresponds to a clinical trial, 20% corresponds to a descriptive study and 10% to a retrospective observational study, in relation to the design and type of study. Results: We found in 100% (10/10) of the studies that the use of ultrasound was effective. Conclusions: It was concluded that the use of ultrasound in the placement of catheters for hemodialysis in patients with chronic renal failure is effective, because it has significant beneficial effects, being successful on the first attempt, reducing the risk of arterial puncture and hematomas. , in addition to facilitating the insertion of central lines, reducing complications for the operators who perform the punctures, as well as reducing morbidity and helping with difficult punctures.

Efficacy of using ultrasonography for the success of peripheral catheterization in patients with difficult venous access
(Universidad Privada Norbert Wiener, 2020-02-16) Cardozo Rodriguez, José Gary; Escobar Valdivia, Jessica Jasmin; Rivera Lozada de Bonilla, Oriana
Objective: Systematize the evidence on the effectiveness of ultrasonography for the success of peripheral catheterization in patients with difficult venous access. Material and methods: This is a systematic review, where 10 scientific articles were reviewed, which were obtained from reliable sources such as scientific journals from around the world, mostly in English. Scientific articles were included that were related to the success or otherwise of peripheral venous cannulations through the use of ultrasonography guidance. Results: Of the 10 articles reviewed in this research, we can conclude that in 8 of the 10 articles reviewed it is mentioned that ultrasonography increases the success rate of peripheral catheterization, reducing the number of attempts, the time used and facilitating the insertion of larger caliber catheters, as well as in the other 2 remaining articles, it is concluded that the successful cannulations obtained in them were the same with or without the use of ultrasonography as a guide. Conclusion: The use of ultrasound guidance increases the success rate in the cannulation of peripheral intravenous lines, especially in patients with difficult venous access.

Efficacy of using ultrasound guidance in catheter placement in patients with difficult vascular access
(Universidad Privada Norbert Wiener, 2019-08-25) Matos Bonifacio, Yeny; Pretell Aguilar, Rosa María
Objective: Systematize the evidence on the effectiveness of the use of ultrasound guidance in the placement of catheters in patients with difficult vascular disease. Materials and Methods: The type and design of the study was quantitative and systematic review respectively, 10 scientific articles made up the population and sample, of 100%, 10% correspond to Spain, 10% correspond to France, 10% London England, 10% Ireland, 30% USA, 10% Great Britain, 10% Canada and 10% Japan. The systematic review of the 10 scientific articles of which according to the type of research design, 10% (n=1/10) are randomized trials, 80% (n=8/10) are a systematic review and meta-analysis, and 10 % (n=1/10) are randomized studies. Results We found in 100% (10/10) of the studies that the use of ultrasound guidance in the placement of catheters in patients with difficult vascular access was effective in older adult patients, children, oncology patients, and diabetic patients who undergo dialysis. Conclusions: 10 of the 10 evidence concluded that the use of ultrasound in the placement of peripheral catheters is effective, because it has significant beneficial effects, being successful on the first attempt, reducing the risk of arterial puncture and hematomas, reducing complications.

Hallazgos intraoperatorios y su relación con los datos ecográficos prequirúrgicos en pacientes con colelitiasis en el Hospital Nacional Alberto Sabogal Sologuren, enero – junio del 2024
(Universidad Privada Norbert Wiener, 2025-10-15) Tineo De la cruz, Lucero Dayanne Venus; Izquierdo Loayza, Jean Jarle
Introducción: La colelitiasis es una patología frecuente en la población peruana, que requiere un diagnóstico ecográfico que sea preciso para poder optimizar el correcto manejo quirúrgico, como evitando las complicaciones que se pueden presentar. Esta investigación partió desde que la se observo la discordancia que se encontraba entre los diagnósticos ecográficos y los hallazgos operatorios, esto podría afectar la planificación correcta y restados post operatorios. Objetivo: Determinar la relación entre los hallazgos intraoperatorios y los datos ecográficos prequirúrgicos en pacientes con colelitiasis en el Hospital Nacional Alberto Sabogal Sologuren entre enero a junio del 2024. Metodología: El estudio fue un hipotético-deductivo, cuantitativo, retrospectivo de corte transversal, con un diseño no experimental. Se aplico una ficha de recolección donde se revisaron 265 historias clínicas de pacientes con colelitiasis que asistieron por consultorio externo; se aplicó una estadística descriptiva e inferencial usando la prueba de Kappa de Cohen. Resultados: Se observo una mayor prevalencia en mujeres (60.4%) y adultos de 40 a 64 años (54%). La ecografía demostró alta precisión en la evaluación del tamaño longitudinal de la vesícula (κ = 0.893) y moderada concordancia en el grosor de la pared (κ = 0.610) y la presencia de líquido perivesicular (κ = 0.603). Sin embargo, se observaron discrepancias en la medición del diámetro transversal y el tamaño de los cálculos (>15 mm). Además, se identificaron hallazgos adicionales intraoperatorios como barro biliar (7.2%) y coledocolitiasis (4.5%). Como también se observó que la ecografía había reconocido 3 casos de colelitiasis que al momento del acto operatorio no se encontró algún litio reportado previamente. Conclusión: Aunque existe una relación significativa entre los hallazgos ecográficos e intraoperatorios, las limitaciones técnicas destacan la necesidad de complementar el ultrasonido con otros métodos en casos complejos. Se recomienda capacitación continua para ecografistas y cirujanos, así como la estandarización de informes para mejorar la precisión diagnóstica.

Macrosomy diagnosis: comparative study between the Johnson method- Toshach and the fetal weighting by ecography in term managers in the San Juan de Lurigancho Hospital in the year, 2018
(Universidad Privada Norbert Wiener, 2018-03-08) Caro Castañeda, Gabriela Veronica; Rodriguez Chávez, Carlos Leonidas
The study was of a cross-sectional retrospective comparative analytical type, where a sample of 208 pregnant women with a diagnosis of macrosomia was taken at the San Juan De Lurigancho Hospital to determine the most precise method for the diagnosis, resulting in confirmation of the null hypothesis since the most accurate method was the fetal weighting calculated by ultrasound compared to the Johnson-Toshach method. According to the sociodemographic results, 45.7% were between 20-34 years old, 66.3% had secondary education and 60.1% were in a cohabiting relationship.
