(20 cards)
What is placenta previa
When the cervix is completely covered by the placenta
Low lying placenta means the placenta is less than how much from the cervix?
2cm
If the placenta is low lying or previa at routine fetal anomaly scan, when do we recommend the follow up scan?
32 weeks gestation
Asymptomatic placenta previa women get given what
Single course of corticosteroids between 34/40 weeks gestation
If a mother is Rh negative, what do we do
A Kleihauer test to determine how much fetal blood has leaked into maternal circulation. And admin Anti-D
Why do we give corticosteroids?
As risk of pre term delivery is significant
In cases of severe bleeding in placenta previa, what do we do
Urgent C-section
Treatment of choice for placenta accreta spectrum
Cesarean section hysterectomy
What is Placental Abruption
Pre mature separation of the placenta from the placental wall
What’s the cause of retroplacental bleeding
Damage to walls of the maternal venous sinuses supplying the placental bed
Couvaire uterus is a sign of what?
Large amount of blood in placental abruption
Management of placental abruption consists of?
Restoring blood loss, preventing coagulopathy, monitoring urinary output, and early delivery
If placental abruption, maternal shock, massive bleeding or closed cervix, how do we deliver?
Emergency C-section
In placental abruption If labor is in progress, or advanced cervical dilation, how do we deliver
Vaginal delivery
What is Vasa Previa
When there are exposed blood vessels next to the fetus
Vasa previa requires urgent delivery via C-section if?
Cervix is not fully dilated
Vasa previa instrumental delivery if?
Cervix is fully dilated and the head is below the ischial spines
