Resumen
El agua es el componente principal del cuerpo humano y
es necesaria para poder mantener una hidratación adecuada de nuestro organismo y
para que este pueda funcionar correctamente. La hidratación además de ser
fundamental para el desarrollo de la vida del ser humano, es muy importante para la
mantención y producción vocal de una manera segura y saludable, en especial para
quienes usan la voz de manera profesional.
La mayoría de los profesionales de la salud, recomiendan
ingerir agua por vía oral, lo que corresponde a una Hidratación Sistémica del
organismo, pero el efecto que esta otorga no es inmediato. No obstante, existe otro
tipo de hidratación llamada Hidratación Superficial, que hidrata de forma más rápida
y permite mantener una cubierta óptima de los pliegues vocales, además de proveer
una adecuada viscosidad de la mucosa que lubrica y recubre estos, permitiendo así
disminuir la resistencia al paso del aire y en consecuencia una menor presión de este
y mayor flujo aéreo (Thomas & Stemple, 2007).
El presente trabajo investigó los efectos que produce la
Hidratación Superficial sobre las medidas aerodinámicas de la fonación, en docentes
universitarios de la Facultad de Ciencias de la Rehabilitación de la Universidad
Andrés Bello.
En este estudio participaron un total de 20 docentes,
quienes se sometieron al proceso de registro de las medidas aerodinámicas de la
fonación, por medio del Sistema Aeroview. Posterior a esto, se les realizó una
Hidratación Superficial, mediante un vaporizador durante diez minutos, previo a
carga vocal. Finalmente, se volvieron a registrar los parámetros aerodinámicos de la
fonación posterior a carga vocal, para comparar y corroborar que después de la
hidratación superficial, las medidas aerodinámicas de la fonación se mantienen.
El análisis estadístico de los resultados fue realizado por
medio de la prueba de t de Student para una significancia del 5% se comprobó que
las variables de Presión Subglótica y Flujo Transglótico, disminuyen
significativamente, pero no se observaron diferencias significativas para la
Resistencia Glótica.
Water is the main component of the human body and is necessary to maintain adequate hydration of our body and to allow it to function properly. Hydration, besides being fundamental for the development of the life of the human being, is very important for the maintenance and vocal production in a safe and healthy way, especially for those who use the voice in a professional way. Most health professionals recommend drinking oral water, which corresponds to a systemic hydration of the body, but the effect it gives is not immediate. However, there is another type of hydration called Superficial Moisturizing, which hydrates faster and allows an optimal coverage of the vocal folds, as well as providing an adequate viscosity of the mucosa that lubricates and overlays these, thus reducing the resistance to Air passage and consequently a lower pressure of this and greater air flow (Thomas & Stemple, 2007). The present work investigated the effects of surface hydration on the aerodynamic measures of phonation in university teachers of the Faculty of Rehabilitation Sciences of the Universidad Andrés Bello. In this study a total of 20 teachers participated, who underwent the process of registering aerodynamic measures of phonation, through the Aeroview System. After this, a superficial hydration was performed, using a vaporizar for ten minutes, before vocal loading. Finally, the aerodynamic parameters of the post-vocal phonation were again recorded, to compare and corroborate that after the surface hydration, aerodynamic measures of phonation are maintained. Statistical analysis of the results was performed using Student's t-test for a significance of 5%. Subglottic Pressure and Transglottal Flow variables were found to decrease significantly, but no significant difference was observed for Glottic Resistance.
