Lesson 8 Flashcards
Low implantation of the placenta in the uterus
Placenta Previa
Premature separation of the normally plantedbplacenta
Abruptio Placenta
Most common cause of painless bleeding in the third trimester
Placenta Previa
Four degrees of placenta previa
Low lying Placenta
Marginal Implantation
Total Placenta Previa
Partial Placenta Previa
Implantation in the “lower” rather than in the upper portion of uterus
Low Lying Placenta
Placenta edge approaches that of the cervical os
Marginal Implantation
Implantation that totally obstruct the cervical os
Total Placenta Previa
Occludes a portion of the cervical os
Partial Placenta Previa
Placenta Previa and Abruptio Placenta occurs in what trimester
Third Trimester
What is the assessment for placenta previa
Painless
Bright red bleeding
What gender of the fetus has the most cases of Placenta Previa
Male
What is the incidence of placenta previa
5 over 1000 women
95% accurate, detects site of implantation
Ultrasonography
Labor that occurs before the end of week 37 gestation
Pre-term labor
Should we perform a vaginal or pelvic exam in women with placenta previa
No/Never
What do you call the “room is swt up for vaginal delivery and emergency cs”
Double set up
What type of bed rest position for pregnant women
Side lying position
Can be used to detect whether the blood originates from the fetus or the pregnant patient
Apt or Kleihauer Betke Test
What are the types of abruptio placenta
Marginal Abruption
Center (concealed) Abruption
Complete Separation
Separates only at the edges causing vaginal bleeding and a little pain
Marginal Abruption
May not result in bleeding by increasing uterine irritability and tenderness
Central (concealed) Abruption
Complete separation from the uterine wall resulting in profuse bleeding
Complete separation
Placenta appears to have implanted correctly, however it begins to separate and bleed
Abruptio Placenta
What is the incidence of abruptio placenta
10 out of 1000
