Why is there bleeding with placenta previa?

Question

I'm 19 weeks of gestation with complete placenta previa, can I take Duvadilan as a tocolytics? Provided that I had painless bleeding one week ago.

Answer 1

Placenta: When placenta is on lower uterine segment, it is called placenta previa. When plans is completely covering the internal os it is complete placenta previa. When the lower segment of uterus gets stretched in last trimester, it distrupts the placenta to cause bleeding.

Answer 2

Maternal vessels.: Placenta previa means that the internal cervical os is covered by trophoblast. When labor occurs, or the amniotic membranes rupture, the placenta starts detaching from the lower uterus, so the maternal blood circulating through the placenta exits from its proper place and manifests as vaginal bleeding (not fetal blood).

Answer 3

Leaky vessels: Previa: Placenta overlies the cervix/birth canal. Gr 1 means placenta is close, Gr 4 means it's directly overlying/blocking the baby's exit -- high chance of preterm labor & bleeding; you'd need a C/S at 36-37wks. More common in woman w/ hx of C/S & smoking. Not much you can do but wait. If dx'ed early, the uterus still grows/stretches and a placenta can migrate away even in 3rd tri. Follow w/ US.

Answer 4

Placenta prevIa: The stretching of lower uterine segment causes the disruption in blood supply to the plaventa. The blood usually comes out of the internal os. So this bleeding is painless. Rarely is there is collection of blood behind placenta than it can be painful.

Answer 5

No contractions.: Because the bleeding does not involve the contractile part of the uterus, only the placenta over the cervix. The placenta is devoid of innervation, therefore the mother does not experience pain in bleeding previa unless preterm labor is also present.

Answer 6

Leaky placental vsls: Previa: Placenta overlies the cervix/birth canal. Gr 1 means placenta is close, Gr 4 means it's directly overlying/blocking the baby's exit -- high chance of preterm labor & bleeding; you'd need a C/S at 36-37wks. More common in woman w/ hx of C/S & smoking. Not much you can do but wait. If dx'ed early, the uterus still grows/stretches and a placenta can migrate away even in 3rd tri. Follow w/ US.

Answer 7

Bleeding: Placenta previa is the placenta implanting over the internal opening of the cervix, and is a very serious problem. It will necessitate you having a caesarean section, as you will not be able to have a vaginal birth. As to bleeding, it can be very serious, and should be reported to your doctor immediately.

Answer 8

Placenta previa: Usually bleeding associated with placenta previa is painless. Rarely, if there is separation of placenta and blood is collected retroplacentally, it can be painful.

Answer 9

Blood => irritation: Previa: Placenta overlies the cervix/birth canal. Gr 1 means placenta is close, Gr 4 means it's directly overlying/blocking the baby's exit -- high chance of preterm labor & bleeding; you'd need a C/S at 36-37wks. More common in woman w/ hx of C/S & smoking. Not much you can do but wait. If dx'ed early, the uterus still grows/stretches and a placenta can migrate away even in 3rd tri. Follow w/ US.

Answer 10

Placenta over cervix: Placenta previa is a complication of pregnancy where the placenta is covering the opening of the uterus called the cervix. It occurs in 1/200 pregnancies more commonly in patients with a previous c section. If diagnosed in early pregnancy it may resolve before delivery. If not a C-section will be needed. It can cause painless bleeding often requiring bedrest.

Answer 11

Placenta over cervix: The placenta, the interface between mother and fetus, is normally located in the upper uterus. If it is in the lower uterus and covering or partially the cervix, bleeding is likely to occur when labor starts. Delivery must be by scheduled c-section. Sometimes such placenta can be abnormally attached to the uterus as well as abnormally located, and this can cause additional complications.

Answer 12

Abnormal implanting: Previa: Placenta overlies the cervix/birth canal. Gr 1 means placenta is close, Gr 4 means it's directly overlying/blocking the baby's exit -- high chance of preterm labor & bleeding; you'd need a C/S at 36-37wks. More common in woman w/ hx of C/S & smoking. Not much you can do but wait. If dx'ed early, the uterus still grows/stretches and a placenta can migrate away even in 3rd tri. Follow w/ US.

Answer 13

Blocks birth canal.: Placenta previa occurs when it implants over the maternal cervix of the uterus, thereby blocking the birth canal and precluding safe vaginal delivery. This is a potentially life-threatening condition that is best managed by experienced obstetrician/maternal-fetal medicine specialist at a large tertiary hospital with blood bank and ICU availability.

Answer 14

See below: It's variable and unpredictable.

Answer 15

Varies: Placenta previa is a condition in which the placenta implants directly over the cervix and blocks the birth canal. For this reason, women with placenta previa require a c-section. Since the placenta is exposed more, it is more prone to bleeding as well. Bleeding ranges from continuous or occasional spotting to torrential hemorrhage that could threaten the lives of both mother and baby.

Answer 16

Unknown: Previa: Placenta overlies the cervix/birth canal. Gr 1 means placenta is close, Gr 4 means it's directly overlying/blocking the baby's exit -- high chance of preterm labor & bleeding; you'd need a C/S at 36-37wks. More common in woman w/ hx of C/S & smoking. Not much you can do but wait. If dx'ed early, the uterus still grows/stretches and a placenta can migrate away even in 3rd tri. Follow w/ US.
