What is the difference between placenta Previa and placental abruption? Flashcards
Placenta Previa
Placenta Previa:
Definition: Placenta previa occurs when the placenta partially or completely covers the cervix, leading to bleeding during pregnancy.
Cause: The exact cause is unknown, but risk factors include previous cesarean section, multiple pregnancies, advanced maternal age, and smoking.
Symptoms:
Painless vaginal bleeding, typically occurring in the third trimester
Bright red bleeding, often sudden and profuse
No abdominal pain or uterine contractions associated with the bleeding
Diagnosis:
Ultrasound imaging is used to confirm the diagnosis and determine the type and extent of placenta previa.
Treatment:
Treatment depends on the severity of the condition, gestational age, and amount of bleeding.
Bed rest, pelvic rest (avoiding sexual intercourse), and close monitoring may be recommended.
Delivery by cesarean section is typically planned if placenta previa persists close to term or if there is significant bleeding or fetal distress.
Placental Abruption
Placental Abruption:
-Definition: Placental abruption refers to the premature separation of the placenta from the uterine wall before delivery.
Cause: The exact cause is often unknown, but risk factors include high blood pressure, trauma, maternal smoking, previous placental abruption, advanced maternal age, and certain medical conditions.
-Symptoms:
Vaginal bleeding, which may be accompanied by abdominal pain and uterine contractions
Dark or clotted bleeding, although some cases may have bright red bleeding
Signs of fetal distress, such as decreased fetal movement or abnormal heart rate
-Diagnosis:
Diagnosis is based on clinical symptoms, physical examination, and sometimes ultrasound imaging.
However, the diagnosis can be challenging as symptoms may vary, and the bleeding may be concealed within the uterus.
-Treatment:
Treatment depends on the severity of the abruption, gestational age, maternal and fetal well-being, and the extent of bleeding.
Management may involve close monitoring, bed rest, intravenous fluids, blood transfusions if necessary, and prompt delivery if there is fetal compromise or severe maternal bleeding.
