Can you tell me how the separation of oxygenated and deoxygenated blood occurs after birth?

Can you tell me how the separation of oxygenated and deoxygenated blood occurs after birth?

Placenta is the key: Once the placental separates from the uterus and the fetus breathes outside, then the flap inside the fetus' heart called the ductus arteriosis closes. The fetal heart now becomes a four chamber heart separating unozygenated venous blood now shunted to the lungs for ozygenation prior to pumping it out the other side of the heart. ...Read more

What is meant by a partial placenta abruption?

Small section, ltd.: Abruption is a bleed from the placenta; a disruption of either the mother or baby's blood supply. Many causes: trauma, high blood pressure, drugs (cocaine), preterm labor, polyhydramnios. Can be very large or very small, so even US can miss a diagnosis. Symptoms: usually preterm contractions, sometimes vaginal bleed. Fetal monitoring is necessary. Wait, watch; abruption can self-heal sometimes. ...Read more

What's the difference between partial placenta previa and placenta previa?

Distance form cervix: 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. ...Read more

One of jehovahs witnesses(no blood) 34 weeks and have partial placenta abr. Doctors are taking a wait and see approach, is this wise given the situation

Yes : The situation warrants close monitoring but in general ultrasound findings of partial abruption do not warrant delivery at 34wks. If you begin to bleed or show signs of fetal compromise that could change quickly. You are at increased risk for heavy sudden bleeding which carries additional risk being a jw and need to continue taking iron, vitamins, etc to minimize risks of anemia. ...Read more

Can you tell me about marginal/partial placenta previa and cn it resolve before your due date?

Yes: Marginal/partial placenta previa is when the placenta comes to the edge of the cervix and maybe even covers a small part of the cervix. Not uncommon on early ultrasounds. As the pregnancy progresses, there is a good chance that this will resolve. If it is still present as you get farther into the 3rd trimester, then it becomes less likely that it will resolve, and a csection may be necessary. ...Read more

Diagnosed with partial/marginal placenta previa (25 wks). Precautions? Worried about preterm labor, placenta has not moved up since 17 wk scan.

Diagnosed with partial/marginal placenta previa (25 wks). Precautions? Worried about preterm labor, placenta has not moved up since 17 wk scan.

Try to relax!: It's still fairly early to be worried. Most patients with marginal placentas deliver vaginally without incident. If this is your first pregnancy your lower uterine segment will not soften until fairly close to term so the placenta may appear to be low until fairly late. As long as there isn't significant vaginal bleeding you shouldn't worry. ...Read more
