artery
Enervated by autonomic nervous system
Two major parts
Body (corpus)
 Cervix

11

Measurement of
fundal height most
accurate from 22-34
weeks
12

Uterine body
 Endometrium
 Innermost layer
 menses
 Myometrium
 3 distinct layers of smooth
muscle
 Middle layer made up of figure-8
patterns of muscle fibers
 Surround large blood vessels
 Perimetrium
 Serous membrane – layer of
viseral peritoneum
13
Internal anatomy, cont.

Cervix




with vagina
~ 2.5 cm long
Dilates to 10 cm
diam. during labor
14
Internal Anatomy, cont.

Fallopian tubes; 10 cm
long

Fertilization usually
occurs in distal third
15
Ovaries

connected to uterus by ovarian ligament

produce estrogen & progesterone

Development and release of ovum
16
The menstrual cycle

Menarche


10 – 14 y/o
Menstrual cycle


21 – 32 day cycle
Ovulation –
menstruation
always 14 days
17
The proliferative phase

At birth, ovaries contain ~ 2,000,000 ova


400 eventually released
The first two weeks



Dominated by estrogen
LH (luteinizing Hormone)surge at day 14
Ovulation
18



FSH (Follicle Stimulating Hormone),
estrogen levels increase
Ovum discharges into abdominal cavity
Cilia on fimbriated ends of fallopian tubes
draw egg into tube
19
The secretory phase



Stage of menstrual cycle immediately
surrounding ovulation
If egg not fertilized, estrogen level drops,
progesterone level dominates
Uterine vascularity increases
20
The ischemic phase


Fertilization doesn’t occur; estrogen,
progesterone levels fall
Vascular changes cause endometrium to
become pale, small blood vessels rupture
21

Post-delivery,
two patients to
manage.
173
Anatomic & physiologic changes
at birth

Respiratory system





non-functional in the uterus
Must now initiate and maintain respirations
in utero, amniotic fluid fills lungs, capillaries
and arterioles of the lung are closed.
Most blood pumped by the heart bypasses the
resp. system through the ductus arteriosus.
1/3 fetal lung fluid is removed during vag.
Delivery.
174


With first few breaths, lungs rapidly fill with
air, , displacing remaining fluid. Pulmonary
arterioles and capillaries open, = decreased
pulmonary vascular resistance.
Resistance to blood flow in lungs is less than
resistance of ductus arteriosus. Blood flow
diverted from ductus arteriosus to lungs. D.
arteriosus eventually closes.
175


After delivery,
maintain neonate
at same level as
vagina with head
@ 15 deg. Below
its torso. Use
DeLee suction
prn.
If neonate does
not cry
immediately,
stimulate by
rubbing its back.
176

Prevent heat loss in neonate

One of the most important risks. Occurs through
evaporation, convection, conduction, or
radiation.
177



Immediately after birth, core temp can drop 1
degree or more
Dry immediately
Ambient temp should be 74-76 deg.
Swaddle
neonate in
warm, dry
blanket.
178
The Apgar Score






Assess at 1 and 5 minutes.
Appearance
Pulse
Grimace
Activity
Respiratory effort



Apgars of 7 - 10 desirable.
Apgars of 4 – 6 = moderately depressed
infant and requires intervention.
Apgars < 4 requires resuscitation
179
The premature infant




Weighs less than 2500 gm (5.5 lbs)
Born before 38 weeks gestation.
At risk for hypothermia, hypoglycemia,
volume depletion, respiratory problems,
cardiovascular problems.
Keep airway clear. Administer
supplemental oxygen, and ventilate prn.
180
The distressed neonate

Meconium aspiration





presence of meconium at birth indicates
possibility of fetal respiratory distress.
Aspiration can causes severe pneumonia.
Suction under direct visualization.
Resuscitation involves ventilation and
oxygenation.
Suctioning, drying, and stimulating infant
is critical
181




Fetal heart rate is the single most important
indicator of neonatal distress.
CO is directly related to HR
Bradycardia results in decreased CO,
ultimately poor perfusion.
A HR of < 60/min. requires CPR.
182
Neonatal resuscitation
Drying, warming, positioning, suction, tactile
stimulation
Oxygen
BVM
Chest compressions
Intubation
Medications
183

Step 1: Drying, Warming, Positioning, Suction,
and Tactile Stimulation.




Immediately after delivery, dry neonate. Place in a
warm, dry blanket. Make sure environment is warm
and free of drafts.
Place infant on its back with head slightly below
body and neck slightly extended. Place small blanket
under shoulders.
Suction neonate again, using a bulb syringe or DeLee
suction trap. (Deep suction can cause a vagal
response). Suction no longer than 10 seconds.
Stimulate by rubbing back, flicking soles of feet.
184

Now assess patient.

RR - rate and depth. BVM prn.

Heart rate - listen to apex of heart with
stethoscope, check pulse at umbilical cord, or
brachial or femoral pulse. If HR < 100, begin
BVM immediately.

Color- If central cyanosis is present, ventilate.

APGAR
185

Step 2 - Supplemental oxygen



Step 3 -Ventilation


blow-by oxygen - warmed if possible.
NEVER DEPRIVE NEONATE OF OXYGEN.
Positive pressure if HR < 100/min., Apneic, or
central cyanosis after administ. Of supplemental
oxygen.
Step 4 - Chest compressions 1/2-1” at 120/min.


If heart rate is < 60/min.
If heart rate is 60-80 but does not increase with 30
seconds of positive pressure vent. And supplemental
oxygen.
186

Neonatal transport



Maintain body temp.
Control oxygen admin.
Maintain vent. Support

 Fundal massage
Observe and monitor vitals
Encourage the mother to breastfeed the
neonate
Keep warm
194
Postpartum Hemorrhage


Any bleeding that results in s/s of
hemodynamic instability (more than 500
cc of blood)
1-10% pregnancies will be complicated
by PPH
195
H&P



Family history of coagulation disorder or
bleeding
Hypertensive meds
Other Causes:
 uterine atony
 lacerations of cervix or vagina
 retained placenta
196




Trauma
Uterine inversion (may be assoc. with
blood loss of 2 liters)
Uterine rupture
Risk Factors include:
 prolonged 3rd stage of labor
 pre-eclampsia
 multiple gestation
 Asian or Hispanic ethnicity
 Multiparous/Multiple gestations
 Polyhydramnios

Trauma in Pregnancy



Frequency greatest in third trimester
 6-7% of all pregnant women
Tachycardia/hypotension may be
significant
Most common cause of fetal death is
maternal shock - 80% fetal mortality
rate.

Estimated at 21 - 25%



Of these, 40% of the time, the abuse began
during the pregnancy
If abused, 18% will suffer miscarriage or
other internal injuries
Abdominal trauma can lead to
 fetal loss
 early labor and delivery of low-weight
or preterm infant
 fetal fractures
 uterine rupture
 chronic illness; hypertension, asthma,
etc.
212
Summary




Remember you’re treating
two patients.
You can care for the fetus if
you care for the mother.
Maintain a high index of
suspicion for complications
Always provide oxygen!
