Simulación por elementos finitos de la termorregulación de la cabeza para tratamientos médicos.

Abstract

Este trabajo expone un modelo de termorregulación que utiliza el método de elementos finitos para realizar un análisis numérico del procedimiento de enfriamiento del cuero cabelludo como contribución a la investigación sobre el uso de hipotermia terapéutica para tratamiento de alopecia causada por quimioterapia. El uso de métodos computacionales de simulación puede contribuir a la construcción y mejoramiento de esta tecnología en nuestro país y así lograr independencia tecnológica, abogando por un desarrollo sostenible. Este novedoso proceder terapéutico puede emplearse en el tratamiento de isquemias en adultos y en neonatología. Inicialmente realizamos la simulación utilizando el método de elementos finitos aplicado a la solución de la ecuación de Pennes del biocalentamiento continuo. Los cambios de temperatura se consideraron utilizando un enfoque de acumulación de sangre .Algunos análisis se realizan utilizando un modelo tridimensional empleando una malla basada en una geometría compleja obtenida a partir de imágenes médicas de tomografía, considerando una manta de enfriamiento. El estudio evidencia que el enfriamiento propuesto causa vasoconstricción de los vasos sanguíneos, que se ha demostrado que reduce el flujo sanguíneo en el cuero cabelludo al 20-40% de la tasa normal, lo que resulta en menos quimioterapia,droga, que se entrega a los folículos pilosos, reduciendo y en ocasiones anulando la perdida del cabello. Una vez más la ciencia se pone al servicio de la vida, logrando converger ciencias tan apasionantes como la mecánica y la medicina.
