Tiempo de sangría

Definición

Es una prueba médica que mide qué tan rápido los vasos sanguíneos pequeños en la piel detienen el sangrado.

Debido a que es difícil realizarlo correctamente, es muy poco utilizado hoy en día.

Forma en que se realiza el examen

El esfigmomanómetro se infla alrededor de la parte superior del brazo. Mientras este dispositivo está en su brazo, el proveedor de atención médica hace dos pequeñas incisiones en la parte inferior del brazo. Estas tienen solamente la profundidad suficiente para causar una pequeña cantidad de sangrado.

El esfigmomanómetro se desinfla inmediatamente. Se tocan las incisiones con papel secante cada 30 segundos hasta que el sangrado se detenga. El proveedor registra el tiempo que toma para que se detenga el sangrado de las heridas.

Preparación para el examen

Ciertos medicamentos pueden cambiar los resultados del examen de sangre.

• Dígale a su proveedor acerca de todos los medicamentos que esté tomando.
• Su proveedor le dirá si debe dejar de tomar temporalmente cualquier medicamento antes del examen. Esto puede incluir dextrano y ácido acetilsalicílico (aspirin) y otros antiinflamatorios no esteroides (AINE).
• NO suspenda ni cambie ningún medicamento sin consultarlo primero con su médico.

Lo que se siente durante el examen

Las pequeñas incisiones son muy superficiales, y pueden hacerse con una lanceta pequeña o con un instrumento especial con un resorte que hace un corte muy superficial. Muchas personas dicen que se siente como un rasguño en la piel.

Razones por las que se realiza el examen

Este examen ayuda a diagnosticar problemas de sangrado.

Resultados normales

El sangrado normalmente se detiene entre 1 a 9 minutos.

Significado de los resultados anormales

El tiempo de sangría más prolongado de lo normal puede deberse a:

• Anomalías vasculares
• Defecto de agregación plaquetaria (problema de agregación de las plaquetas, uno de los componentes de la sangre y que ayudan a que esta se coagule)
• Trombocitopenia (bajo conteo de plaquetas)

Riesgos

Existe un riesgo muy bajo de infección donde se ha cortado la piel.
