1

Birth process

3 stages w

1) labor: 12 hours 1St Bebe, 6 after
Cervix dilates
Push fetus to vagina
Cervix displayed to 10 cm
Pain: contractions increase in frequency and intense to dialate cervix

2)delivery: 1/2 to 1 hour
Moms effort to push fetus through cervix and out of uterus
Less frequent contraction (60-90sec)
Crowning:babies head appears at putter opening of vag

3) delivery of placenta and uterus
Contract until placenta and Umb cord are out
Few min to half hour
Whole placenta must be out or continue to bleed
Breast feed can expel it quicker or oxytocin injection

2

Episiotomy

Incision to make vag bigger

Shorten by 15 to 30 min

Critics say unnecessary
1970 90%
2000 20%

Birth complications

1) failure to progress and breech
-longer than normal so they walk nap or get an enema meds oxytocin to stim the contractions

Breech presentation: feet/butt in breech position
Dangerous because Umb cord can restrict
Midwifes massage while using medicine by 37th week

2) c-section, cesarean delivery
Can't breech progress or any problems this is the answer
Cut baby from uterus
2000 year practice but babes would die or mothers
Until sterile and antibiotics
Help with stds
Cost more and dr get payed more
But not higher rates
Vbac vag birth after csection

11

Neonatal jaundice

Yellow skin of baby in first days due to immature liver

If like after few days problem
Fix via phototherapy (expose to blue light)
Cause brain damage

12

Anoxia

Can't breath when hit oxygen

Minutes can cause perm damage

13

Apagar scale

0-3- life threatening
4-6- req assist to breath
7-10- good to excellence condition

Appearance blue- pink
Pulse absent to fast
Grimace ( reflex) none to cough sneeze cry

Respiration no breath more than 1 min to good breath with cry

98% us babes fall in 7-10

Two times
Minute after birth
Then 5

Rates determine risk of death in first month

14

Brazelton scale

27 items

Stun response
Cent nervous system stability

Day after birth
Then two months

Increase parent confidence

15

Low birth weight
Preterm
Small for date

<2500g 5.5lbs

Preterm- babes born at 37 weeks or less

Small for date: term for neonates who weigh less than 90% of other babes born at same age

World rate: 14%

As and af highest rates euro lowest

16

About low birth and effect on neonate

Very low birth weight less than 3.3 at birth
Extreme low birth less than 2.2 lbs

Born preteen
Us 50% survive if born pre 25 weeks

Why?
Malnutrition illness disease teratogens

Physical systems not good immature infection vulnerable
Lack Fat to insulate
Lungs

17

Surfactant

Helps them breath and keeps air sacs from collapsing

Preterm haven't developed this

Fatal consequences

Breath tube help

18

Treatment of low birth weight

Kangaroo care moms and dad place preterm infant on skin on chest 2-3 hours a day during early weeks of life

Highly beneficial breath body temp heart rate sleep cycles

More likely to survive

Infant massage
Isolette- sterile chamber with oxy and control temp
Weight gain

Though low weight later problems
Physical cognitive allergies
Language delays poor school performance

19

20/200 or 20/600
Best at 8-14 inch
