Which of the following circumstances is most likely to cause uterine Atony and lead to PP hemorrhage *?
After the placenta is delivered, these contractions help compress the bleeding vessels in the area where the placenta was attached. If the uterus does not contract strongly enough, called uterine atony, these blood vessels bleed freely and hemorrhage occurs. This is the most common cause of postpartum hemorrhage.
Prevention tips Prioritize your postpartum health. Start thinking about your postpartum care plan before you give birth.

It usually happens within 1 day of giving birth, but it can happen up to 12 weeks after having a baby. About 1 to 5 in 100 women who have a baby (1 to 5 percent) have PPH.

Treating subchorionic hematomas While most subchorionic bleeding heals on its own, your doctor may recommend activity modifications such as pelvic rest. If your blood type is Rh-negative, your doctor may recommend receiving the RhoGam injection to prevent problems in future pregnancies.
When the placenta attaches to the muscular walls of the uterus instead of the lining of the uterine walls, delivery becomes harder and often results in severe bleeding. Blood transfusions and even a hysterectomy may be required. This complication is called Placenta Accreta.
About 1 in 100 to 5 in 100 women have postpartum hemorrhage. It is more likely with a cesarean birth. It most often happens after the placenta is delivered, but it can also happen later.
Complications include sterility, uterine perforation, uterine synechiae (Asherman syndrome), urinary tract injury and genitourinary fistula, bowel injury and genitointestinal fistula, vascular injury, pelvic hematoma, and sepsis.
In several drug information resources, adverse effects on hemostasis such as afibrinogenemia, hematoma formation and bleeding are mentioned for oxytocin;[22,23,24,25] while in this study these kinds of complications have not been evaluated, but our findings (decreasing of K and increasing of α and MA in increased …
Uterine atony is a failure of the uterine myometrial fibers to contract and retract. This is the most important cause of PPH and usually occurs immediately following delivery of the baby, up to 4 hours after the delivery.
Risk factors for postpartum hemorrhage among the deliveries were: fetal macrosomia (over 4000 g); pregnancy-induced hypertension; pregnancy generated by assisted reproductive technology; severe vaginal or perineal lacerations; and weight gain over 15 kg during pregnancy.
In addition to preparing your perineal floor for birth, Kegel exercises during pregnancy can help prevent hemorrhoids by improving circulation to the area. Sleep on your side. And not your back (which you shouldn’t be doing anyway after your first trimester) — this reduces pressure on the affected area.

Therefore, prolonged oxytocin treatment leads to OXTR desensitization, thereby limiting further oxytocin-mediated contraction responses. We propose that prolonged oxytocin treatment leads to OXTR desensitization that interferes with uterine contractility, leading to uterine atony and PPH.
Misoprostol stopped bleeding as rapidly as did oxytocin and with a similar quantity of additional blood loss [among women receiving prophylaxis].”
Subchorionic bleeding does not usually cause any problems. However, research on whether SCH can cause pregnancy complications, such as preterm delivery or pregnancy loss, varies. For example, a 2012 review found possible links between SCH and a higher risk of giving birth prematurely and of pregnancy loss.
Ultrasonographically detected subchorionic hematoma increases the risk of miscarriage in patients with vaginal bleeding and threatened abortion during the first 20 weeks of gestation. However, it does not affect the pregnancy outcome measures of ongoing pregnancies.
It’s best to be on your side. Many people say the left side is better because of where the uterus is, but many women rotate from side to side. Some will put a pillow under the hip to help rotate them a bit.
