Attitude
Position
Station

Perfectly

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

Flexion or extension
( mad, fist! ). (Relax, spread out )

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

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

How well did you know this?

Perfectly

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

Perfectly

How long does it take so the baby cone head goes back to normal?

Couple of days

How well did you know this?

Perfectly

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

How well did you know this?

Perfectly

What are the 3 presentations we can feel during fetal presentation?

Cephalic
Breech
Shoulder

How well did you know this?

Not at all

Perfectly

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

Overall the biggest problem with any type of breech is that the ?

Head is gonna get stuck or body get stuck

There is another thing called a brow cephalic, which is? Why is this also bad?

Where the forehead is coming out , like instead of the top of the head, it’s like your forehead The fontanlles can’t mold, so it gets stuck

When you’re doing a vaginal exam, what are the two boney process you want to feel for?

Ischial spine

What does position of the baby mean, professor definition?

Where the body of the baby is in to relationship to where the ischial spine is

When the baby isnt passed the ishcial spine, what do we rate it?

Negative 1-5 whatever

What the baby is passed the ischial spine, what do we rate it?

+1-5 then delivered

THE SUPER IMPORTANT THING TO NOTE IS THAT WHEN THE BABY IS TRYING TO GO DOWN, IT CAN TRICK US TO BELIEVE ITS FURTHER DOWN THAT IT IS BECSUSE OF THE FONATANLLES MOLDING ( THAT CONE SHAPE ) SO ITS IMPIRTSNT TO?

Walk your fingers back to the suture lines to use to measure the position of the baby to the ischial spine

What is the anterior fontanel? What’s the shape

It’s a obstetrical landmark because of its distinctive diamond shape

So when you’re putting your fingers in to feel for the baby, the vaginal exam, you feel the baby head and the diamond shape, what does that mean or like what would you write?

Baby is vertex ( cephalic ) OA

What’s the most ideal position for a baby to be born?

What does LOA and ROA mean?

So OA means it’s coming down head first in its optimal position however The diamond shape is leaning towards the mothers left leg Or the mother right leg ( just a little bit slanted )

What does OP feel like and mean?

Y shape!! Where the baby is coming down chip up! But still the head

So what does LOP and ROP mean?

the baby is coming head doen, but instead it’s chin is facing up because you can feel a Y shape So LOP Is that the chin/ Y shape is slanted to the left side of mother leg Or the baby chin/ y shape is panted to the right side of mother right leg

What does the fetal lie mean? The most basic definition of?

How the baby is lying down Side to side Up to down Down to up

Since passenger is also fetus and placenta, what does it mean for placenta, how does it matter for labor?

Where is the placenta? Like low line? Going to come out before the baby?

What are the primary powers? What do we want to know about this?(6)

Contractions Frequency, duration, intensity Effacement Dilation Ferguson reflex

How does contractions play a role with dilation?

The body contractions in order to put pressure on the baby to put pressure onto the cervix in order to dilate

How does the contractions and dilations play a role with primates? A female first time giving birth?

It takes time to dilate it, so you go through stages 1-10 stages of dilation

What does effacement mean?

How thick the cervix is, long

We don’t really care as much of the centimeters, but more so care for?

If you’re making progress of growth

What is the secondary power? How does this happen?

Pushing So once the cervix is completed dilated 10CM It’s time to push

If mother is in so much pain, she can inhibit labor, so it’s best we tell mom to what?

Try to change position, find a comfortable way

What does labor mean?

Process of moving fetus, placenta and membranes out of the uterus and through the birth canal

What are the 2 big signs of preceding labor? What normally is primate?

Lightening/dropping Bloody show Primary - everything, lightening

When do we know true labor starts, like what are the two big signs during the third trimester before labor? This then allows us to know that true labor contractions have started If this doesn’t happen, we know the contractions are just Braxton hicks

Plug of mucous and blood Amniotic sac ruptures ( water breaking )

The the contractions pull on the thick tissues of the cervix causing it to thin, this is also called?

Effacement

What is the first stage of labor ? What are 2 phases? How does the contractions start off as then go into ?

When the body is starting to dilate Latent and active In latent they start off as irregular Then into active they get more controlled or regular enough that she’s continuing to change her cervix

Normally for a primate, mother who’s never had a baby, what happens in the first stage of labor, or when does she go through active labor? And a multip

Usually a little bit later, around 4-6cm Usually zooms through these phases by fast!

If the amniotic sacs hasn’t ruptured before, during active labor it will?

Yes it will

How do we know when wr go into the second stage of labor?

When the cervix is fully dilated

During the second stage of labor, mainly know as the pushing stage, it’s now the babies turn to be able go through the pelvis, what’s the the 3 ps that help the baby?

Power ( pushing from the uterine contractions ) Passenger ( fetus go ) Passage ( birth canal )

Notes Things she’s saying in the video She’s mentions how it’s super important that the we know how the baby is position and how it’s going to fit through. Like the best attitude for the baby to be in is being flexed So the chin is down at the chest and the head can mold But if it’s extended it won’t mold properly So that’s why most babies need c section to be removed

What is the best fetal lie ?

Longitudinsl ( ideal ) down top Spine is with mom spine

What does transverse fetal lie mean? What does oblique mean?

Side to side Kinda at an angel

During the second stage of labor, we have cardinal movements , or simply put it as, the baby moving down for birth. What does descent mean? How does this play with fetal station?

Downward movement of the grid to pelvic inlet How down the baby is moving to be delivered into the world Or think of how we said before, feeling those suture lines to see how close it is to the pelvic ischial spines

When does the third stage of labor begin?

When the baby is fully delivered And the placenta is going down to be removed

What is the 4th stage of labor?

Adaptation to blood loss Start of the uterine involution ( going back to how it was before )

First starts : dilation is starting Second ends : dilation is full Second starts : dilation fully /push Second ends : baby is delivered Third starts : baby is delivered Third ends : placenta is delivered Fourth start : recovery period

How do we know we are in the first stage of labor?

True labor contractions

How do we know they are true labor contractions?

When we dilate the cervix!!! When we see the progression of getting bigger cervix!!

Stages of labor First stage is ?

Onset of regular uterine contractions to full dilation of the cervix

Second stage of labor ?

From the time the cervix is fully dilated to the birth of the infant

Third stage of labor?

From the birth of the infant until the placenta is delivered

What’s the fourth stage of labor?

Begins with the delivery of the placenta and lasts until the woman’s condition is considered stable in the immediate postpartum period, usually within 1 hours after giving birth

What does mechanism of labor mean?

The turns and adjustments necessary in human birth process

What are the 7 cardinal movements of mechanism of labor?

1. Engagement 2. Descent 3. Flexion 4. Internal rotation ( head moving for fontanells to mold ) 5. Extension 6. External rotation ( restitution ) 7. Expulsion

What is normal fetal heart rate?

110-160

Why does fetal respirations matter during labor or more so change?

No longer mom doing it They gotta do it!
