The probability of manual abruption of the placenta is still relatively small for pregnant women. When a pregnant woman has a normal delivery, the placenta is usually removed automatically as the uterus contracts and is subsequently delivered. If the placenta adheres to the uterus, the placenta will be removed by hand. Placental adhesion is not particularly common in pregnant women, but is usually seen in patients with a history of multiple abortions and uterine surgery, so the probability of manual abruption is low. If the placenta is removed successfully and the uterus contracts well, there is usually no major impact on the mother. However, if the hand-expelled placenta is not removed smoothly, and there are cases such as retained placenta, hemorrhage and post-partum discharge may occur, which is very unfavorable to maternal health. Pregnant women should go to regular hospitals to give birth, and should not panic too much if there are situations such as placental adhesions.
