Nombres alternativos

Prueba de perfusión ácida

Definición:

Es un método para reproducir síntomas de acidez gástrica y generalmente se realiza junto con otros exámenes para medir la función esofágica.

Forma en que se realiza el examen:

La prueba se realiza en un laboratorio de gastroenterología. Se introduce una sonda nasogástrica (NG) a través de un lado de la nariz y se baja hasta el esófago. Se introduce ácido clorhídrico suave a través de dicha sonda, seguido de una solución de agua con sal (salina). Este proceso se puede repetir varias veces.

Se le solicitará comentarle al equipo médico cualquier dolor o molestia que tenga durante el examen.

Preparación para el examen:

No se puede comer ni beber nada durante 8 horas antes del procedimiento.

Lo que se siente durante el examen:

Usted puede experimentar una sensación nauseosa y algo de molestia cuando se coloca la sonda en su lugar y es posible que el ácido cause síntomas de acidez gástrica. También puede presentarse dolor de garganta después de la prueba.

Razones por las que se realiza el examen:

Esta prueba intenta reproducir los síntomas del reflujo gastroesofágico (ácidos estomacales que se devuelven hacia el esófago).
