ObGyn Amniotomy + Bleeding + Fetal bradycardia

In any clinical scenario when all of sudden you have profuse vaginal bleeding after performing amniotomy and a fetal compromise shortly follows then you have to immediately think of Vasa Previa.
The boards loves to ask about Vase previa.

High Yield points include:
  • Risk factors: velamontous insertion of the umbilical cord, accessory placental lobe, and multiple gestation.
  • Vaginal bleeding is typical painless making some confusion with placenta previa.

thanks sabio...
but i want to add another point over here...
there is another clue for differentiating between vasa previa and placenta previa
in VP-there is fetal compromise as the bleeding is from fetal vessels and in PP there is maternal compromise as the bleeding is from maternal vessels

Am I wrong but is vasa previa not a rupture of the umbilical vessels most times?

FHT should go tachy --> brady --> sinusoidal.
