Placenta Previa is one of the main causes of bleeding during pregnancy or during labor. Bleeding at the time of pregnancy and childbirth is one of the emergency because it can endanger the mother's life. Thus, special handling is necessary during pregnancy and delivery in the case of Placenta Previa.
The placenta is the part that affects the uterine wall and serves as a supplier of oxygen and nutrients to the fetus in the womb. Normally, the placenta attaches to the side or top of the uterus. However, in the case of Placenta Previa, the placenta attaches to the bottom so as to cover part or all of the cervix. The closing of this birth canal does not allow the baby to be born normally, because the placenta that was hit by the baby will rupture and cause bleeding. Cesarean delivery (sc) is a way to prevent and minimize bleeding.
In early pregnancy, the placenta is located at the bottom of the uterine wall. As the pregnancy age increases, the fetus and uterus become larger. The size of the enlarged uterus makes the placenta attracted and shifts to the upper part of the uterine wall. If the gestational age has entered the third trimester but the placenta remains at the bottom of the cervix, this condition is called Previa.
Some of the trigger factors of Placenta Previa are:
a. The shape of the uterus is not normal
b. The number of previous pregnancies is quite a lot
c. Smoke
d. Pregnancy in old age
e. Never do a cesarean section or surgery that leaves a mark on the side or top of the uterine wall so that the placenta can not stick in place.
