Fluidoterapia reflexiva: desde la fisiología a la práctica clínica / Reflexive fluid therapy: From physiology to clinical practice

Introducción. La fluidoterapia es una intervención ampliamente usada en la práctica clínica. No obstante, su aplicación no está exenta de riesgos y demanda una evaluación cuidadosa de la tolerancia del paciente y su respuesta al volumen. La práctica empírica de la reanimación con líquidos puede ser potencialmente letal. El propósito de esta revisión fue proporcionar una visión general de los principios fisiológicos y terapéuticos para la administración de líquidos intravenosos en pacientes críticamente enfermos, abordando poblaciones especiales, como los pacientes quirúrgicos, sépticos y politraumatizados. Métodos. Se hizo una revisión narrativa a partir de artículos publicados en PUBMED, ScienceDirect y LILACS, entre 2001 y 2023. Para la búsqueda se emplearon los términos MESH fluid therapy, crystalloid solutions y colloids. Resultados. Se encontraron 371 artículos, de los cuales se seleccionaron los estudios clínicos aleatorizados, las revisiones narrativas, las revisiones sistemáticas y los metaanálisis que analizaron el rol de los cristaloides y coloides. Se incluyeron manuscritos publicados en fechas por fuera del rango de búsqueda, que se consideraron relevantes para la descripción de la fisiopatología y los fundamentos del uso de líquidos endovenosos. Conclusión. La reanimación reflexiva se fundamenta en un entendimiento holístico de la fisiología y la individualización de la fluidoterapia. El uso liberal de líquidos endovenosos tiene potenciales efectos nocivos y las estrategias de reanimación deben ser guiadas por medidas dinámicas y estáticas individuales, que proporcionan un panorama seguro para el manejo de los líquidos.

Introduction. Fluid therapy is an intervention widely used in clinical practice. However, its application is not without risks and requires a careful evaluation of patient's tolerance and response to volume. The empirical practice of fluid resuscitation can be potentially lethal. The purpose of this review was to provide an overview of the physiological and therapeutic principles for the administration of intravenous fluids in critically ill patients, addressing special populations, such as surgical, septic, and trauma patients. Methods. A narrative review was carried out based on articles published in PUBMED, ScienceDirect, and LILACS between 2001 and 2023. MESH terms fluid therapy, crystalloid solutions, and colloids were employed. Results. A total of 371 articles were found, of which randomized clinical trials studies, narrative reviews, systematic reviews, and meta-analyses that analyzed the role of crystalloids and colloids were selected. Manuscripts published on dates outside the search range, which were considered relevant for the description of the pathophysiology and the rationale for the use of intravenous fluids, were included. Conclusion. Reflective resuscitation is based on a holistic understanding of physiology and individualization of fluid therapy. The liberal use of intravenous fluids has potential harmful effects and resuscitation strategies should be guided by individual dynamic and static measures, which provide a safe framework for fluid management

Eutanasia y estigma: ¿El derecho a la muerte digna es contrario a la ley universal? / Euthanasia and stigma: is the right to a dignified death contrary to universal law?

Resumen: La palabra eutanasia (del griego "eu" (bueno o feliz) y "thanatos" (muerte)( designa a un procedimiento cuestionado por múltiples grupos sociales y religiosos. Las personas que la practican, como sus familias, son estigmatizados por sus detractores. A pesar de que Colombia es uno de los pocos países que ha regulado esta práctica desde el 2015, incluso permitiéndola en menores, el proyecto de ley no ha pasado los debates en el Congreso, y los intentos de acceder a él se ven frustrados por trámites burocráticos (1). Este artículo de reflexión tiene como objetivo abordar el concepto de la eutanasia desde la filosofía, historia, medicina y la jurisprudencia.

Abstract: The word euthanasia (from the Greek "eu" (good or happy) and "thanatos" (death)) designates a procedure questioned by multiple social and religious groups. The people who practice it, like their families, are stigmatized by their detractors. Despite the fact that Colombia is one of the few countries that has regulated this practice since 2015, even allowing it in minors, the bill has not passed the debates in Congress, and attempts to access it are frustrated by procedures bureaucratic (1). This reflection article aims to address the concept of euthanasia from philosophy, history, medicine, and jurisprudence.

Online-synchronized clinical simulation: an efficient teaching-learning option for the COVID-19 pandemic time and: beyond.

Face-to-face clinical simulation has been a powerful methodology for teaching, learning, and research, and has positioned itself in health science education. However, due to the COVID-19 pandemic, social distancing has forced universities to abandon simulation centers and make use of alternatives that allow the continuation of educational programs safely for students and teachers through virtual environments such as distance simulation. In Latin America, before the pandemic, the use of non-presential simulation was very limited and anecdotal. This article has three main objectives: to establish the efficacy of online-synchronized clinical simulation in the learning and performance of medical students on the management of patients with COVID-19 in simulation centers of three Latin American countries, to determine the quality of the online debriefing from the students' perspective, and to deepen the understanding of how learning is generated with this methodology.

Cognitive load and performance of health care professionals in donning and doffing PPE before and after a simulation-based educational intervention and its implications during the COVID-19 pandemic for biosafety.

INTRODUCTION: The Personal Protective Equipment (PPE) is essential to avoid the COVID-19 spread to health care workers. Its use can be difficult, posing a high risk of contamination, mainly during doffing, then with the risk of becoming infected. METHODS: We conducted a prospective before-and-after design that used clinical simulation as a research methodology in a clinical simulation center of Colombia. A simulation-based educational intervention with two cases related to COVID-19 was proposed in the emergency room and the intensive care unit. We conducted A workshop for donning and doffing of personal protective equipment (PPE) and a debriefing after the first case. RESULTS: In the pre-test, 100% of participants failed donning and doffing PPE, 98.4% were contaminated, only one-person did not contaminate out of. The mean cognitive load was high (7.43±0.9 points). In the post-test, 100% were successful in donning the PPE and 94.8% in doffing; only 9.8% were contaminated. The mean of the cognitive load was low (4.1±1.4 points), and the performance was high (7.9±1.1). Of the total, 73.8% of participants reported overload in the doffing. The most difficulties were in gown/overall, and N95 mask removal. DISCUSSION: The PPE donning and doffing is critical and may be changed significantly by active training. In responding to the current COVID-19 pandemic in 2020, activities of training in donning and doffing PPE would provide a means of training personnel, reducing the cognitive load and maybe the risk of contamination and infection of health care workers.
