What does the harm of placenta previa have

summary

Love pregnancy has been very smooth, but before the pregnancy test, the diagnosis of placenta previa, is not very clear about this phenomenon, very afraid of the development of the fetus. Let's take a look at the hazards of placenta previa.

What does the harm of placenta previa have

First of all: after the baby is born by caesarean section, the obstetrician will deliver the placenta, and give the mother injection of oxytocin (or other drugs to promote uterine contraction), these drugs will make your uterine muscle contraction, help the placenta attachment site hemostasis. But if it is placenta previa, the attachment site of the placenta is below the uterus, where the uterine contraction is not as strong and powerful as the upper uterine contraction, and this weak uterine contraction can not effectively help stop bleeding, which will lead to postpartum hemorrhage.

Second: if there is placenta previa, the placenta is more likely to be planted too deep in the myometrium (placenta accreta), so it is not easy to peel off during delivery. Placenta accreta occurs only once every 2500 deliveries, but in every 10 cases of placenta previa, there will be 1 case of placenta accreta. Placenta accreta can cause very serious bleeding. Sometimes hysterectomy for hemostasis and blood transfusion are needed.

Finally: pregnant women with placenta previa are more likely to give birth to babies with lower weight, most of which are due to the earlier delivery time of the baby, but some of them are due to the slightly higher risk of intrauterine growth restriction if the expectant mother has placenta previa.

matters needing attention

Pregnant women should reduce their activities and rest in bed. If they have abdominal pain, bleeding and other symptoms, they should seek medical advice immediately. Usually pay attention to keep the vulva clean, frequently wash underwear, to avoid the occurrence of infection.
