What is the definition of Abruptio Placentae?

1. Complete detachment of the placenta before delivery

2. Partial or full detachment of normal implanted placentae at more than 20 weeks

3. Placenta previa with bleeding

4. NORMAL placental attachment late in pregnancy

The correct answer is: Partial or full detachment of normal implanted placentae at more than 20 weeks

Abruptio placentae, commonly referred to as placental abruption, is defined as a condition where the placenta detaches partially or completely from its normal implantation site in the uterus prior to delivery, typically after 20 weeks of gestation. This separation can lead to significant complications for both the mother and the fetus, such as fetal distress due to reduced blood flow and oxygen, and maternal hemorrhage. Choosing this option as the correct answer captures both the timing and the nature of this serious obstetric emergency. It highlights the critical timeframe of the event occurring after 20 weeks of pregnancy, which is essential for identifying the condition in a clinical setting. While other choices may incorporate elements related to placental issues, they do not accurately reflect the specific details of abruptio placentae. For instance, total detachment can indeed occur, but the definition includes the possibility of both partial and complete detachment occurring in a critical timeframe. Additionally, the mention of placenta previa, though relevant to placental disorders, refers to a distinct condition where the placenta is improperly positioned and does not relate directly to the detachment seen in abruptio placentae. Finally, normal placental attachment does not apply to the definition of this condition, as it indicates a healthy connection
