Final answer:
Placenta previa and abruptio placenta are two different conditions involving the placenta during pregnancy. Placenta previa occurs when the placenta covers the opening of the cervix, while abruptio placenta is the premature separation of the placenta from the uterus.
Step-by-step explanation:
Placenta previa and abruptio placenta are two different conditions that involve the placenta during pregnancy. Placenta previa occurs when the placenta partially or completely covers the opening of the cervix, while abruptio placenta is the premature separation of the placenta from the uterus.
Placenta previa can cause painless vaginal bleeding during the second or third trimester of pregnancy and is usually diagnosed through ultrasound. It is important for the mother to be cautious and seek medical attention if vaginal bleeding occurs. On the other hand, abruptio placenta is associated with painful vaginal bleeding, abdominal pain, and a firm uterus. This condition requires immediate medical attention as it can be life-threatening for both the mother and the baby.
In summary, placenta previa involves the covering of the cervix by the placenta, leading to painless vaginal bleeding, while abruptio placenta is the premature separation of the placenta from the uterus, causing painful bleeding and abdominal pain.
