lp5- presntations and videos Flashcards
prep
culture
emotions
Childbirth prep and classes–childbirth education classes help emotionally and physical prepare for birth
Culture-different for each culture-be respectful and integrate practices
lots of uncertainty, some overjoyed/ cant wait or some can be nervous/can be frightened, all depends
Common fears r/t childbirth-
losing child,
easily frustrated,
expected performance,
raising children,
how supportive is their partner
, things never being the same in vaginal area
changing lifestyle
pain, image
What attributes to a positive birth experience-
what are the parts of it
more education=better experience.-childbirth education classes help emotionally and physical prepare for birth
Birth plan supportive people, whose in room, where giving birth, if at home or hospital to provider special needs like meds and postpartum
What causes labor to start?
when is fetus matured
no for sure answer, generally Increased oxytocin/ Prostaglandin to induce contractions with decreased progesterone
uterine muscle stretches
fetus is pressing on cervix
Corticotropin releasing hormone (CRH)
Placenta may reach age
potentially semen
-Fetus matured at 37-42 weeks-
Early signs of labor
lightening
Lightening- “Dropped”-lower baby, pressure in groin/bladder, bladder urgency and incontince, easier to breath, waddling gait, lower edema, leg cramps pelvic pressure
Braxton hicks
ripening
bloody show
early signs of labor
Braxton hicks-practice contractions-painful to some but not all-does not mean in labor
Ripening-softening of cervix
Bloody show-loss of mucus plug like 24-48 hrs before labor- if too much then go get emergency care
Nesting and 1 more
early signs of labor
Nesting-sudden burst of energy for 24-48 hrs beforehand
Rupture of membranes
prostaglandin surge
signs of early labor
Wt loss
Diarrhea
Nausea
indigestion
Rupture of membranes
Nitrazine paper-test
sometimes
what +/-
test if membrane that has ruptured amniotic fluid or not
sometimes it could be urine
urine will be negative, amniotic fluid is positive
Prolapsed cord
can do what
how do you help situation
rupture of membrane
-umbilical cord falls out before baby head is engaged
can cut circulation off to baby-very dangerous
-put steril glove on and push babys head up into vaginal area into cervix so baby is not compressing cord
false labor
true
common
moms need what
true labor needs cervical changes
false labor is common-urine can come out instead of membranes
moms need lots of reassurance, they can be very anxious and nervous
Components of Labor
4 p’s
Passage – woman’s pelvis-maternal pelvis shape
Passenger - fetus
Powers – uterine contractions/factors-how powerful to push out baby
Psyche – woman’s psych. State or mind, coping, how dealing with hormones and pain
fetal skull molding
-ability of babys head to mold and flex to be able to squeeze out vagina during birth
fetal skull
fontanelles sutures
facilitate the movement and molding of the cranium through the birth canal during labor.
They also allow for rapid postnatal growth and development of the brain.
fetal attitude flexion
how flexed is fetus so that smallest part of head exits first
fetal lie
what 2 ways
fetal presentation
Longitudinal -north to south-preferred
Transverse-side to side
presenting part
normal
Malpresentations(B/T)
fetal presentation
Cephalic-head down
Malpresentation –breach and transverse lie
//B-may need c section because feet,bottom out first
/T- risky,gambling, baby coming out sideways, doctor may need to pull baby so it doesn’t breach
engagement measurements
head is what
Engagement-head down.
Head is engaged into cervix.
Once it hits 0 station(around area of isheac spine) it is engaged into birthing process
station measurements
how measure
full ____ baby upwards
Station-0=head is engaged
-anything above that is negative cm.
once out in below of cervix, then it is positive numbers
baby head progress–
-3
-2
-1
0
1
2
3
full bladder can push baby upwards
fetal positons measuemrents
anterior
posterior
transverse
dependent on where baby is sitting-ideally loa
. if baby is ROA-then heartrate is in right lower abdomen
if baby is LOA-then heartrate is in left lower abdomen.
Anterior is lower abdomen,(LOA,ROA)
posterior is upper abdomen,(LOP,ROP)
transverse is outer part (LOT,ROT)
Leopold’s maneuver
can palpate fetal back, butt, extremities
Vaginal exam
what feeling for
if not engaged
when is 0
During a vaginal exam, your doctor will feel for your baby’s head, cervical effacement,sofetening,dialtion and where baby is
If the head is high and not yet engaged in the birth canal, it may float away from their fingers. At this stage, the fetal station is -5.
When your baby’s head is level with the ischial spines, the fetal station is zero
FHR
methods
normal
Methods-dopler, ultra sound, fetal scope
Normal rate-110-160
3-Fetal assessment -Common location of FHR
ROA and LOA are normal and most common positions,
so heart rate in lower abdomen
breach position FHR
if heard upper
breach means what
which means hr is heard where
if FHR is heard in upper abdomen it could mean breach position
Breach means baby is flipped upward woth feet, butt going first,
so it would be in upper part of abdomen, not lower
cardinal movements of labor
descent/flexion
internal roation
extension
external rotation
expulsion
Descent, flexion,- baby’s head hitting the soft tissues of the pelvis, align head w/ chin toward chest as they get into pelvic cavity
internal rotation-when in pelvic floor, head will rotate
, extension-ead passes through the pelvis at the base of the neck-face and neck appear outside of body
, external rotation-head moved from face down to side
, and explusion-shoulder out
Powers of labor-
buildup of contractions in its longest phase-beginning of one to end of same contraction
primary powers of labor
frequency
duration
intensity
Primary-how much and how often
Frequency of contractions-start of one to start of other
Duration of contractions-60 seconds
Intensity of contractions- some pain, tightening pushes baby out
powers of labor secondary
what are they
are they
length
Effectiveness of pushing-
are contractions strong enough and are they frequent enough to actually push out-don’t want too much time
Length of labor- may take longer if newer, can push 2-3 hrs sometomes
Contractions phases
increments
acme
decrement
Increment-upward intensity phase
Acme-peak intensity
Decrement-downward intensity
contractions descriptions
frequenct
duraion
intensity
Frequency-start of contraction until next one starts
Duration-start to end of one contraction
Intensity-how intense it gets
Cervical Changes
true
effacement
dilation
cervix has to change for it to be true labor
Effacement- shortening of cervical canal, cervix is paper thin, then it is 100% effaced.
Dilatation/dilation- opening that increases to 10 cm. do not want mom pushing before full dilation
Cervix effacement
Cervix starts off as long and thick, then cervix will shortnen to give baby less travel tme out of cervix
Cervix will keep thinning out to allow easier push, amniotic fluid will break, membranes will rupture
1st stage - how long/much
true onset
all three 3 stages
1st stage – true onset of labor until 10 cm dilation-
true onset is cervical change
latent
active
transition
Latent
how dialted
contractions
keep
start
-0-3 cm dilated,
mild contractions, 20-40 seconds,
keep mom active at this point
start birth plan
active
dialtef
contractions
more
spontaneous
4-7 cm,
contractions last 40 -60 seconds every 3-5 minutes-
more pain and anxiety,
spontaneous rupture of membranes-closer to delivery
Transition-
how dialated
contractions
membranes
how will mother feel
is this pt ready for birth
use what to check cervix/why
8-10 cm,
2-3 minutes part, 60-70 second contractions,
if rupture of membrane hasn’t happen it wont fully dilate. -doctor will rupture membrane for them
Intense and uncomfortable, reaction of vomit, pain, anxiety, irritable, pressure, wants to push, shaking, hyperventilating,
definitely ready ,
use sterile gloves to check cervix, wait until 10 cm to push– if lots of burning or urge to push, and lots of pressure need to check
what happens if mom pushes before 10 cm
vaginal area will swell and won’t fully dialate
labor will not fully progress and most likely c section
promoting comfort in labor
bp

pa
wa
re
br
b/b
Birth plan,
touch,
pain,
walking, relaxation,
breathing,
bladder/bowel – keep empty to assist with fetal descent
2nd stage of labor
how dilated
crowning
stretching
check on
provide
10 cm dilation until birth of baby
Crowning-severe pain, burning in vaginal canal-head is right there
Stretching of perineum and anus-massage of areas to prevent mom from tearing so baby doesn’t go out too fast and keep mom comfortable
check on cervial and assess patient
provide comfort and push
3rd stage of labor-what is it
SS
DD
takes how long
do not want what
do not do what
– placenta separation and expulsion
“Shiny Schultze”-blue side that faces baby
“Dirty Duncan”-side on uterine wall-where attached-
from 5-30 minutes-
do not want any placenta in mother-want all of it out of body, not much pain, cord is attached but already clipped off of baby
do not pull on placenta
Comfort
4th stage of labor
-what is
moms
time
increase in
first 4 hours after placenta delivery
Mom’s recovery and physiologic readjustment
Time wanting to spend with baby,
increase in urine function dt fluid loss, usually can take 2 weeks
Contraction Assessment
palpation
electronic
–external
–internal
Palpation-touch and feel them happenin
Electronic monitoring
External –toko belts on abdomen
Internal-right into baby scalp inside vagina, is most accurate way but used less often
FHR Assessment
variability:-need what
absent
minimal
moderate
marked
fetal Brady
fetal tacky
Variability-difference between highest and lowest hr
need a 2 minute strip
Absent-no range detected
Minimal- 5 beats or less
Moderate-6-25 beats
Marked-greater then 25 bpm
Fetal brady- less then 110 for 10 minites
Fetal tachy-more then 160 for 10 minutes
accerlations
what are
how long
usually
Accelerations are short-term rises in the heart rate of at least 15 beats per minute,
lasting at least 15 seconds
usually 2 minutes or less
