Cervical dilation balloon can open a few fingers

The balloon is usually placed in the delivery room after dinner. After the balloon is placed, there will be obvious uterine contractions throughout the night. Some pregnant women with better cervical conditions can open more than three centimeters directly on the night after the balloon is placed, and then the balloon will come out from the vagina. This is the most ideal result. Most people put in the balloon, the next morning when the balloon is removed, the cervix will accommodate about 2 fingers, forming a water sac, and then artificial rupture of the membrane, if necessary oxytocin drip. Cervical balloon oxytocin, success rate is still relatively high.
