Q

What is cervical insufficiency?

A

Sometimes called cervical incompetence. Anatomical defect. Means cervix dilates and effaces (without pain) in second trimester. Weight of baby contributes to cervix’s inability to hold baby in place. Results in spontaneous abortion.

Q

What is perinatal loss? What can we do?

A

Loss of pregnancy in any stage.
“I am so sorry for your loss. What can I do that would helpful to you today?”
Support and listen. Don’t be in a hurry. “Do you want to talk?” Allow them to see, touch, hold and spend time with this baby. They will hold onto those memories for a long time. Prepare baby to look and smell his best. Do not hide any defects but allow them to examine and say goodbye. Prepare a memory packet and help them practice how they will tell others. (including siblings)

25
What is treatment for pre-eclampsia?
Depending on the severity The goal is to allow baby to develop as long and safely as possible. Kick counts, reduce BP, activity restrictions. No reversal, just control until pregnancy over. Try to deliver vaginally. Mag Sulfate, steroids, antihypertensives, anticonvulsants
