caridad is a 26 year old, G1PO, at 28 wga. Her pregnancy so far has been uneventful expect for some spotting during the first six weeks. Caridad smokes 3 to 4 cigarettes a day.
Case study
Caridad calls the prenatal clinic to say that earlier this morning she had felt her baby move a lot. she said the movement was so violent that it actually hurt her. Now she realizes that she has not felt her baby move again all day. She is told to come in, and the baby's heart tones are checked. They cannot be located. An ultrasound is ordered, and the diagnosis of fatal demise is made.
Questions
Is there a relationship between the spotting during the first trimester and later intrauterine fetal death (IUFD)?
Caridad is not experiencing any bleeding or cramping at this time. what is the probability hat she will go into spontaneous labor soon?
if she does not go into labor, how will the pregnancy be terminated?
what are the risk for Caridad if she decides to wait for her body to naturally go into labor
