Resumen
Objetivo: Analizar las evidencias científicas contemporáneas sobre las barreras clínicas, organizativas y profesionales que limitan la implementación de la movilización precoz en adultos ingresados en Unidades de Cuidados Intensivos. Métodos: Revisión integradora desarrollada según el marco de Whittemore y Knafl, con búsquedas em bases de datos PubMed, SciELO, LILACS, Scopus y Web of Science (2021-2026). Se utilizó el modelo PICO para la selección y extracción de datos de 09 artículos de alta relevancia, centrándose en las barreras asistenciales y los criterios de seguridad. Resultados: Los hallazgos demuestran un cambio de paradigma de "intensidad máxima" a la "precocidad prudente". Las principales barreras identificadas incluyen la inestabilidad hemodinâmica y la sedación profunda (clínicas), el miedo del equipo ante eventos adversos (profesionales) y el déficit de personal aliado la escasez de tecnologías de apoyo (organizativas). La sistematización través del bundle ABCDEF y el uso del "Semáforo de Seguridad" surgen como estrategias cruciales para mitigar la inercia terapéutica y la debilidad adquirida. Consideraciones finales: El estudio evidencia que el éxito de la movilización precoz depende de la superación de barreras culturales y estructurales mediante la gobernanza clínica. La principal limitación reside en la heterogeneidad de los protocolos entre los centros de cuidados intensivos.
