17
Q

What is a variable deceleration

A

V or W shaped
that may or may not be associated with a contraction
Less than 30 seconds to nadir

18
Q

What does a variable deceleration show

A

Partial cord occlusion leads to a decrease in venous return which causes
baroreceptor mediated acceleration in HR → Hypertension and decreased arterial
oxygen tension

Cord compression

19
Q

What is a late deceleration

A

Starts after a contraction and ends after a contraction

20
Q

What does a late deceleration mean

A

Fetus vasoconstricts → baroreceptor response → decrease in HR

Utero-placental insufficiency

Hypertonus and hypotension

21
Q

What are the interventions for recurrent variable decelerations

A 
Side to side positioning 
knee to chest position 
IVF bolus
turn off the oxytocin 
02 by facemask 
tocolytics 
amnioinfusion
22
Q

Describe the contraction pattern in minutes

A

q3 to 5 minutes
Quiet or none
Irritable

23
Q

What does tocometry measure

A

The timing of contractions

24
Q

What do you need to have a place to measure contraction strength

A

IUPC

25
Q

How many Montevideo units is an adequate contraction

A

Greater than 200

26
Q

What is tachysystole

A

More than five contractions in 10 minutes

27
Q

How do you treat tachysystole

A

Terbutaline

28
Q

What is a reactive NST

A

<32 Weeks - 2 accels of 10 beats/minute above baseline for 10 seconds duration

> 32 weeks - 2 accels 15 beats/minute above baseline for 15 seconds duration

Do this for 20 minutes

29
Q

What is the most common cause of a non-reactive NST

A

Fetal inactivity or feet of sleep

30
Q

Next step if NST is non-reactive after 40 minutes

A

BPP

31
Q

What is a contraction stress test and how is it done

A

Place mother in semi Fowler’s position and stimulate contractions

3 contractions in a 10 minute period lasting 40-60
seconds are stimulated

32
Q

What is a negative contractions stress test

What is a positive contraction stress test

What is an unsatisfactory contraction stress test

A

No late or variable decelerations

Late decelerations with at least half of the contractions

Lesson three contractions in 10 minutes

33
Q

When should you avoid a contraction stress test

A

Placenta previa or a previous classical cesarian

34
Q

What does a biophysical profile show And how long does it last

A

Fetal acid-base status and intact CNS

Can last up to 30 minutes

35
Q

How is the BPP scored

A

Two points for each category max of 10

36
Q

Name all of the categories in the BPP

A

Gross body movements: Three body movements in 30 minutes

Fetal Tone: One episode of extension with return to flexion

Amniotic fluid volume: A pocket that is 2 x 2

Fetal breathing: One episode of more than 30 seconds

A reactive NST

37
Q

How to manage a score of eight or 10

A

Repeat at weekly or biweekly intervals

38
Q

What to do with a score of six

A

It greater than 36 weeks repeat in 4 to 6 hours. Deliver if oligohydramnios

39
Q

What to do with the score of four

A

If >36 weeks, deliver.

If <32 weeks, repeat
score.

40
Q

What to do with a score of 0 to 2

A

Extend to 120 minutes deliver if persistent

41
Q

What is a modified BPP

A

It is a reactive NST and then AFV with a 2x2 pocket
