The difference between placenta praevia and early abruptio placenta lies in their different concepts, symptoms and medications.
1. Different concepts: Placenta praevia means that after 28 weeks of pregnancy, the placenta is positioned lower than the prenatal part, attached to the lower part of the uterus or covering the endocervical opening. Placenta previa refers to the partial or total detachment of the placenta from the uterine wall after 20 weeks of pregnancy or during labor and delivery of the fetus.
2. Symptoms: Placenta praevia can be manifested as repeated vaginal bleeding in late pregnancy or after labor without any cause and without pain. Placental abruption is characterized by abdominal pain, vaginal bleeding, persistent contractions, uterine pressure and other symptoms.
3. Different medications: In the treatment of severe placenta previa, commonly used medications include diazepam and other sedatives, dexamethasone and other glucocorticoids, nifedipine and other calcium blockers, magnesium sulfate and other drugs to inhibit uterine contractions, and emergency cesarean sections are used to terminate the pregnancy if necessary.
As for placenta previa, after the delivery of the fetus, drugs for uterine contraction are mainly given, and the commonly used drugs are hysteronin, prostaglandin preparation, ergometrine, etc. to prevent postpartum hemorrhage. For patients with shock, oxygen and blood transfusion should also be given to correct the shock, and the pregnancy should be terminated promptly if necessary.
Patients with placenta praevia and placenta previa should consult the doctor in time, complete the relevant examinations, clarify the cause of the disease under the guidance of professional doctors, and actively treat the disease.
