    Transcript
    Now let's discuss Antepartum Hemorrhage. So there are several causes of Antepartum Hemorrhage. But these are the most common. Placenta previa, Placenta abruption, Vasa previa and then uterine rupture. Let's talk about placenta previa first. So placenta previa is a condition in which the placenta is in front of the baby covering the cervical os. Now how do you if a patient has placenta previa? Well, there's a few things that they will present with. The first and the most important is that they have painless vaginal bleeding. You'll see this is different in some of the other presentations where there is pain associated with the vaginal bleeding. For patients that have a placenta previa, you want to make sure that you do not perform a digital or speculum exam. Doing so could disrupt the placenta and that mom could hemorrhage to death. Because the placenta is in front of the cervix, our management delivery by C-section. So let's move on to placental abruption. Placental abruption happens when placenta prematurely separates from the uterus. You can have a concealed or internal hemorrhage from that or you can have external bleeding if it's significant enough. Now what are the causes of placental abruption? Hypertension is the most common. But also trauma, cocaine or tobacco use or quick decompression of the uterus. So for example, a mom that has polyhydramnios, extra fluid, when her water bag ruptures, the uterus decompresses very quickly. And that can actually lead to placental abruption. So vasa previa is a condition where the vessels traverse the cervical os. As you can see in the picture, the vessels are in front of the fetal head. Now this can be very traumatic for labor, specially if you have artificial rupture of membranes. If you do this, you will actually...
