Q

Position

Study These Flashcards
A

Position of mother

Squatting is the best

24
Psychological
Mother needs to be cooperative | Breathing and relaxing techniques
25
Fetal Head
Largest part | BPD measures the head
26
Presentation
Head up or head down
27
Vertex
Head up | IDEAL!
28
Breech
Butt first
29
Cord Prolapse
Cord falls between baby legs | Very dangerous
30
Fetal Position
Put 2 fingers up vagina Feel how dilated the mother is Feel the head/butt
31
ROA and LOA
Best positions | Right and left anterior
32
Transverse Position
Hard for birth
33
Posterior Position
Harder for the mother | More painful
34
-4/-5
Can feel the head | Long way to go
35
+2/3
Ready for delivery
36
+5
Crowing and out
37
"In labor"
Regular contractions | Dilation
38
Cervix during labor
About 1hr per cm 10-12 hr for 1st pregnancy Multiple pregnancies= much faster
39
Fundus
Where the contractions start
40
Effacement
``` Thinning 2cm thick at first 10% long way to go 80% really thin 100% paper thin ```
41
Position during Labor
Squatting is most powerful No squatting with epidural Change position between contractions Try not to lay all the way down
42
Epidural Caution
Too early = stop contractions Too late = baby will be limp Give around 5/6 cm dilated
43
First stage of Labor
Onset of dilation To 10cm Most variable
44
Second stage of Labor
Full dilation to birth | Within one hour (hopefully)
45
Third stage of labor
Birth until placenta is delivered | Within minutes
46
Fourth stage of labor
2 hours after delivery of the placenta
47
Engagement
Head is in the pelvis
48
Descent
Goes a little farther down
49
Flexion
Baby brings head in and compresses itself
50
Internal rotation
Baby moves towards the mom
51
Extension
Stretches out completely
52
Restitution
Turns head | External rotation
53
Expulsion
Baby comes out!
54
Coroamitilis
Bag of water has ruptured prematurely | Lots of bacteria
55
Onset of labor
Week 39/40
56
Preceding labor
About 2 weeks before baby is dropping | -5 in pelvis, better breathing but more pressure
57
Bloody Show
Mostly mucus | NOT a sign of labor
