(Universidad Privada Norbert Wiener, 2019-09-22) Martinez Vera, Yasmina Tatiana; Rosales Clemente, Raquel Nelly; Bonilla Asalde, César Antonio
Objective: Systematize the patents on the effectiveness of skin antisepsis for the prevention of infection in patients who require the use of a peripheral venous catheter. Materials and Methods: Systematic Reviews are scientific inquiries, where the element of exploration is the unique primary works. It is a fundamental instrument for the synthesis of scientific reference, increasing the value of study results and in turn identifying areas that need to be investigated. It is executed using a strict methodology and high quality control to avoid erroneous conclusions. The investigation is limited to writings with complete content. Those chosen were subjected to a thorough investigation, using the grade system that allowed us to record the strength of recommendation. From the final choice, 10 articles were selected, of which we found that 20% (02) belong to the country of Japan and France, while 10% (01) correspond, respectively, to Canada, Portugal, Singapore, and the United Kingdom. , United States and Ireland. Among the randomized clinical trials we find studies from Canada, the United Kingdom, France with 70% and systematic reviews from Portugal, the United States and Singapore with 30%. Results: Of all the articles analyzed, 80% affirm that chlorhexidine is more effective than the use of other antiseptics in preventing infections. Conclusions: The research reviewed shows that there is effectiveness of skin antisepsis with chlorhexidine compared to other antiseptics in preventing infections in patients requiring a peripheral venous catheter.

Influence of the time and angle of inclination of the centrifuged tube during the decantation process on the leukocyte count of the urinary sediment
(Universidad Privada Norbert Wiener, 2020-02-26) Gallegos Galván, Elizabeth; Ortiz Gómez, María Elizabeth; Sandoval Vegas, Miguel Hernán
Urinalysis is the second most common laboratory test, and its proper performance during the process, especially in the evaluation of urinary sediment, is essential. The goal of our study was to determine the influence of the time and angle of inclination of the centrifuge tube during the decantation process on the leukocyte count in urinary sediment. A descriptive, cross-sectional, prospective experimental study was conducted, collecting 100 urine samples from patients at a private clinic in northern Lima. All samples met the inclusion criteria and quality control standards, and the leukocyte counts were evaluated according to the Clinical Laboratory Standards Institute (CLSI) GP16-A3 protocol. From the total samples, 89% were women. The frequency of cases with or without variation in the leukocyte count, at decantation angles of 135º and 180º and times of 2 and 1 seconds, showed that 12% and 23% had the same count (p=0.040). A significant influence of the time and angle of inclination of the centrifuge tube during decantation on the leukocyte count in the urinary sediment was determined.

(Universidad Privada Norbert Wiener, 2025-09-26) Garcia Luyo, Jhon Carlos; Borja Velezmoro, Gustavo Adolfo
El presente estudio es el nivel de control de calidad en el proceso laboratorial de láminas cervicouterinas, siendo un problema en el sistema de salud es importante prevenir y reducir el incremento del cáncer de cuello uterino con la detección temprana y oportuna con el examen de Papanicolaou, con un control de calidad desde la recolección de la muestras con su respectivas ordenes ,fijación, tinción microscópicas de las láminas y con la gestión de confiabilidad de los resultados con una la adecuada identificación de lesiones del cáncer cuello uterino e identificando la implementación de estándares de calidad. Objetivo: Identificar el nivel del control de calidad en las fases del proceso de laboratorio de láminas cervicouterinas en un hospital nacional público de Lima, 2025. Material y metodología: Se desarrollará un estudio de tipo básico, no experimental, método inductivo de diseño transversal, nivel descriptivo – prospectivo. La población pertenece a las Láminas cervicouterina enviada al área de citología del Hospital en el periodo de abril 2025, se estudiarán aproximadamente 3500 extendidos cervicouterinas. Resultados: Se identificó el nivel de control de calidad en la fase preanalítica mostrando un nivel de calidad “bueno” con un 100% de la disponibilidad de documentos y procedimientos, en la fase analítica el nivel de control de calidad se identificó “regular” con un 70% y un 30% malo y por ultimo en la se post analítica se identificó “bueno” con un 90% y con 10% malo. Conclusión: Luego de analizar los resultados obtenidos se puede concluir donde se verifico el cumplimiento de los diferentes documentos y procedimientos en el laboratorio de citología de Hospital Nacional Público, siendo en la fase preanalítica el nivel de control de calidad “bueno”, en la fase analítica “regular”, y en la fase postanalítica “bueno”.

Quality Parameters of Platelet Concentrates Obtained by Leukocyte-Platelet Layer at Alberto Sabogal Sologuren Hospital, 2018
(Universidad Privada Norbert Wiener, 2018-06-19) Alvarez Trujillo, Teresa; Cueva Tolentino, Magdalena Macaria; Paredes Arrascue, Jose Antonio
The objective was to determine the compliance with quality parameters of platelet concentrates obtained by the leukocyte platelet layer method." Material and Methods: This is an observational, descriptive, cross-sectional study determining the compliance with quality parameters such as pH, volume, swirl phenomenon, storage temperature, platelet count, residual leukocyte count, and microbiological study of platelet concentrates. Random sampling with a 95% confidence level resulted in a sample size of 384 platelet concentrates. Results: 50.8% of the platelet concentrates met the optimal platelet count, and other parameters were met as follows: 90.1% for plasma volume, 99.5% for required pH, 97.1% for the swirl phenomenon, and 100% for residual leukocyte count and microbiological control. Conclusions and Recommendations: It was concluded that platelet concentrates meet quality parameters for plasma volume, pH, residual leukocyte count, swirl phenomenon, and microbiological control. The quality parameter not meeting the established requirement was platelet count. Therefore, it is recommended to monitor and evaluate compliance with quality standards by standardizing the processes in the extraction, production, and storage of platelet concentrates.

(Universidad Privada Norbert Wiener, 2022-06-02) Siesquen Silva, Jaime; Champa Guevara, Cesar Alfonso
The aim of the study was to determine the relationship between pre-analytical variables and the performance of coagulation profile tests at Lambayeque Hospital in 2021, following global standards such as WHO, CLSI, and ISO. This was a hypothetical-deductive study with a quantitative, correlational, applied approach, examining pre-analytical procedures in the hemostasis laboratory of a public hospital. Variable 1 and its dimensions include patient preparation, tourniquet application time, tube order, mixing, specimen volume, centrifugation, and special specimen handling. Variable 2 and its dimensions included basic coagulation profile tests, validated through expert judgment, with a representative population of 2600 users and a sample size of 427, considering inclusion and exclusion criteria. SPSS was used to generate frequency tables for errors, chi-square, and Pearson tests for nominal scale variables. It was demonstrated that there is a relationship between pre-analytical variables and the performance of coagulation profile tests.
