Chapter 16 Flashcards
What are the 5 factors that affect process of labor and birth?
Passesnever
Passageway
Powers
Position
Psychologic response
What are the two examples of passenger?
Fetus and placenta
What is the Example of passageway?
Brith canal
What is the example of powers?(2)
Primary?
Secondary?
Contractions
Pushing
What does position mean?
How the mother is positioned
She is in a position to deliver a baby? Standing?
What are the 4 pelvis ?
- Gynecoid
- Anthropoid
- Andriod
- Platypelloid
What is the most favorable pelvis?
Gynecoid
( pumpkin shape )!! ( round shape )
What’s the second most best pelvis?
Anthropoid( oval shape )
( human face shape )
What is the worst type of pelvis we don’t want mothers to have?
And can lead mothers to getting a what?
Andriod type
( alien shape pelvis )
( heart shape )
( poor prognosis & c section )
What is the flat pelvis called?
Platypelloid
( flat !! )
( poor prognosis & possible c section )
When looking at the passenger ( the fetus and placenta ), we like to look at 5 things, what are they?
Presentation
lie
Attitude
Position
Station
What is the definition of presentation and lie when regarding the care of the passenger ( fetus and placenta )?
- Presentation is part of fetus entering the pelvic inlet first
- Relationship of maternal long axis ( spine ) to fetal long axis ( spine )
This can be transferred or longitudinal ( parallel )
^ pretty much how the baby is facing with the lie, is it ready for birth? Head down? Or is it on its side, back/butt first
What is the definition of attitude when regarding parts of the passenger ( fetus and placenta )?
Relationship of body parts to another
Flexion or extension
( mad, fist! ). (Relax, spread out )
What does position mean when regarding the passenger ( fetus and placenta )
Literally how the baby is position,
Head down and chin down
Head down and chin up?
Feet down ?
Etc
What does station mean when regarding the parts of the passenger ( fetus and child )
Fetal presentation part in relation to the maternal ischial spines
How far fetus progressed down birth canal
( so measuring how far the baby has moved down to prepare for birth from the ischial spine, to coming head out )
So we know that powers equals to uterine contractions and pushing, but what does uterine contractions mean or do?
Used to think and dilate the cervix while pushing the fetus to be expelled
What are 3 key terms to know when regarding uterine contractions ?
Duration : how long a contraction last
Frequency : how often contractions occur
Intensity : how strong the contractions are
Why does psyche mean when regarding the 5 Ps?
The maternal stress
Anxiety
Etc
So calm the patient!
When regarding the passanger, the fetus in this case, we know that the biggest thing to get through the pelvis, is the fetal head, how does the fetus get through?
The bones in the fetal skull, the fontanels in particular, can change shape, or MOLD!! To fit through the mothers pelvis
The reason why the fetus is able to have fontanels molding is because it needs to get through.this is why we babies have those ??
Really long cone shape heads
How long does it take so the baby cone head goes back to normal?
Couple of days
The reason why most patients who have really bad pelvis shapes or simple the baby doesn’t mold, is the reason why we ?
Have a lot of c sections because the head won’t get through
What does fetal presentation mean, professor definition?
When you do a vaginal exam and you find the cervix and you touch the first part of the baby , and what you’re feeling is the baby presentation
What are the 3 presentations we can feel during fetal presentation?
Cephalic
Breech
Shoulder
What is cephalic presentation?
Presenting part is the occiput( vertex )
( the head )
What is the breech for fetal presentation ?
Presenting part is the sacrum
( butt or feet )
What is shoulder presentation ?
Presenting part of the scapula
( shoulders )
There are two types of breech presentation, what are the names and definition of each?
Foot lane breech ( where the feet are down )
Frank breach ( butt down )
Most of the time, some people have difficulty telling the difference between a frank breech ( butt ) and a cephalic ( head down ) when feeling for a baby presentation. How can you tell?
Butt is always softer!!!
Head will be hard
Why do we not deliver foot lane breechs as often or usually?
Because the head applies a lot of pressure on the cervix to dilate
However when the feet are down, they aren’t really applying pressure to dilate
Meaning it’s not gonna be big enough or stretched out enough to fit the whole baby
So big pain for mom!
Can cause severe neurologic damage
Why don’t we give frank ( butt ) breech births as often?
Because the butt is soft. The uterine contractions try its best to push and allow the cervix to thin and dilate. However when there isn’t pressure cause the butt is soft
No pressure is gonna be applied to dilate
Making labor longer and more painful
