RESUMEN

Introducción: La hemodinamia es la parte de la biofísica que se encarga del estudio anatómico y funcional del corazón, de la dinámica de la sangre en el interior de las estructuras sanguíneas, así como de la mecánica del corazón.
Objetivo: Comparar la hemodinamia con el dispositivo no invasivo USCOM antes y después de presentar hemorragia controlada.
Material y métodos: Se realizó un estudio tipo observacional, prospectivo, longitudinal y comparativo en pacientes de entre 16 y 65 años de edad en un periodo de seis meses como fecha corte para este premio académico (marzo de 2016-proyecto aún en curso).
Resultados: Se obtuvieron promedios de las diferentes variables hemodinámicas, de precarga, postcarga e inotropismo, observando cambios tempranos a la exanguinación de los pacientes, siendo principalmente las resistencias vasculares sistémicas las que se modifican.
Discusión: Existen cambios hemodinámicos tempranos a la exanguinación de pequeñas cantidades de sangre en los pacientes, cambios determinados por el sistema USCOM, sistema fácil de usar, no invasivo y preciso en los resultados ofrecidos.
Conclusiones: En este estudio podemos observar cómo las variables relacionadas a la postcarga (resistencias vasculares sistémicas) son las primeras variables que se modifican, por lo que con la pérdida de pequeñas cantidades de sangre llegamos a observar esto.
