Problems with the MVA
The syringe is full
When the syringe is mostly full, it will not have enough vacuum to empty the
rest of the tissue out of the womb.
Solution:
1. Take the syringe off of the cannula, leaving the cannula
in the womb.
2. Empty the syringe.
3. Make a new vacuum in the syringe: Push the button down
and in to close the valve, and pull back the arms until they
snap out at the end of the syringe barrel.
4. Gently attach the cannula to the syringe again.
5. Open the valve by pushing the button toward yourself
to continue emptying the womb.
The cannula becomes clogged
Solution:
1. Remove the syringe and cannula
from the womb and take the
syringe off of the cannula.
2. Empty the syringe.
3. Put a new, sterilized cannula into the womb.
You may need a larger-sized cannula.
4. M ake a new vacuum in the syringe: Push the
button down and forward to close the valve,
and pull back the arms until they snap out at the
end of the syringe barrel.
5. Gently attach the cannula to the syringe.
6. O pen the valve by pushing the button toward
yourself to continue emptying the womb.
Sometimes there is a piece of tissue stuck in the cervix that continues to clog the
cannula. You may be able to remove it with a pair of sterilized forceps.
