Análisis biomédico de la espectroscopia de impedancia: Una nueva herramienta en cuidado crítico
Contenido principal del artículo
Resumen
La degradación de la mucosa gastrointestinal juega un papel clave en la evolución del choque y ha sido reconocida como el "motor de la falla orgánica múltiple". Aún no existe una tecnología capaz de monitorear daño debido a isquemia en la mucosa gastrointestinal y que ayude a guiar apropiadamente la terapia de reanimación del paciente críticamente enfermo. El objetivo de este trabajo es dar a conocer el desarrollo de una nueva tecnología de invasión mínima, dirigida al diagnóstico temprano del daño isquémico de la mucosa gastrointestinal, mediante espectroscopia de impedancia utilizando una sonda con cuatro electrodos. Se citan algunos trabajos de evaluación y validación. Los resultados experimentales indican que la estimación de daño isquémico con esta tecnología es viable y establece su potencial como una herramienta en el monitoreo del paciente críticamente enfermo. Por último, se establece la perspectiva de desarrollo para la aplicación de esta tecnología en el Instituto Armado.
