antenatal testing

Question 1

why do we preform antenatal testign

Answer 1

for high risk pregnancy or for decreased fetal movements. this is to assess fetal well being

Question 2

what is first test for antenatal testing?

Answer 2

non stress test

Question 3

what does the NST look for?

Answer 3

fetal heart rate variability and accelerations

Question 4

what is a reassuring NST

Answer 4

accelerations and variability are present

accelerations: if >32wks (15X15; 2/20min) if <32wks (10X10; 2/20)

Question 5

what if fail NST?

Answer 5

then repeat NST with vibroacustic stimulation…if pass then reassured

Question 6

what if fail NST with VAS

Answer 6

then perform Biophysical profile

Question 7

what is the BPP

Answer 7

assess baby using further criteria 
1) NST
2) AFI
3) breathing 
4) movement
5) tone
0-10 score

Question 8

what are the interpretations of the BPP scores?

Answer 8

0-2 fetal demise imminent –need C-section
3-7 need to weigh pro and cons of delivery vs leaving in
8-10 reassuring, leave baby alone.

Question 9

what is an AFI, what is normal and what is abormal

Answer 9

amniotic fluid index. >5 is normal; 8-25 is reassuring.

Question 10

what if AFI is <5

Answer 10

possible ROM, or oligohydramnios. indicative of kidney issues.

Question 11

what if AFI >25

Answer 11

indicative of gastrointestinal issues with baby

Question 12

what is a CST?

Answer 12

contraction stress test. looks at baby HR during adequate contractions
there should not be any bradycardia or decelerations.
if there are late decels or bradycardia then fetal demise is imminent –C-section
