What is a fetal non stress test?
|
it's a general test of fetal well being. It measures the fetal hr in response to fetal movement
|
|
|
The normal response is to see some accelerations
|
If the fetus is non-reactive, this is non-reassuring
|
|
|
What is the next step if you don't see accelerations on the monitor?
|
you can do vibroacoustic stimulation
|
|
|
Also, if you get a non-reactive fetal NST then you might start considering emergent C/S or induction
|
ok
|
|
|
The fetal HR tracing is up on the top
|
The contraction tracings are the bottom tracing
|
|
|
What would you do for a lady that is not responding well to oxytocin and you get a non-reassuring fetal status?
|
you might want to proceed with a C/S
|
|
|
Terbutaline can slow down contractions but
|
would not be good in a patient with bradycardia
|
|
|
What are late decelerations a sign of?
|
uteroplacental insufficiency
|
|
|
What does a variable deceleration look like on the tracing?
|
shows an acute fall in FHR with variable recovery
|
|
|
The reason they are variable is that they can show very quick or very long recovery
|
ok
|
|
|
What causes variable decels?
|
umb cord compression
|
|
|
What causes early decels?
|
head compression
|
|
|
Late decels actually begin at or just after the peak
|
they are due to uteroplacental delivery
|
|
|
This example was a sinusoidal pattern
|
ok
|
|
|
The true sinusoidal pattern is a regular,smooth, undulating form typical of a sine wave that occurs with a frequency of two to five cycles/minute and an amplitude range of five to 15 beats/minute. It is also characterized by a stable baseline heart rate of 120 to 160 beats/minute and absentbeat-to-beat variability.
|
ok
|
|
|
What is a good first step if you detect uteroplacental insufficiency on the FHR tracing?
|
you should put them in left lateral decub position
|
