LABOR
Series of events that take
place in the genital organs
in an effort to expel the
viable product of
conception (fetus,
placenta and the
membranes) out of the
womb, through the vagina
into the outer world is
called labor.
The third stage of labor ----- interval from the
deliveryof the babyto the separation andexpulsion of the
placenta
Normally the delivery of placenta will take about5-10
minutes after delivery of the baby regardless of theparity
The major complication associated with this period is
postpartum hemorrhage (PPH)---- the most common cause
of maternal morbidity andmortality in developing
countries.
THIRD STAGE PHYSIOLOGY
Normal placental separation
Placental separation occurs due to shearing of the placental surface
when the uterus contracts after the infant isdelivered
After delivery of
the baby

Principles in the management of third stage of labor to prevent PPH
Rapid and complete
separation of placenta
Prevent from
PPH
Strong uterine
contraction
Occlude spiral
arterioles andveins
Stop bleeding
Uterotonic drugs
Uterine contractions play the majorrole

Steps of placental delivery
Gush of blood (VULVA SIGN)
Does not signify complete separation
Lengthening of the umbilical cord (CORD
SIGN)
Uterine fundus palpable beyond the umbilicus
Uterus become round in shape
Signs of placental separation
Vulva sign means only placental separation is going on
but does not signify complete separation
Cord lengthens for more than 3inches (8-10cms)
When pushing the uterus upward the cord will not
follow
Tests for complete placental separation
Spontaneous uterine contractions,
Downward pressure from the developing retroplacental
hematoma
An increase in maternal intraabdominal pressure
Placental expulsion follows as a result of
Sudden gush of blood
Lengthening of the cord
Expression of the Placenta
Delivery of the placenta
Longer duration----more PPH
Average 5-6 mins
90% placenta delivered in 15 mins
97% in 30 mins
Preterm---longer duration
Retained placenta---more likely in very early GA
Duration of the third stage of labor
Expectant management
MANAGEMENT OF THIRD STAGE OF LABOR
Expectant management
Spontaneous delivery of the placenta without
the useof uterotonic agents or cordtraction
Delivered by maternal expulsive force and
gravitational force
The placenta may be incomplete separated or
entrapped inthe lower uterine segment or upper
vagina
Takes more time
More bleeding
Active management
Early cord clamping
Administration of a uterotonic agent prior to placenta
separation.
Controlled cord traction
Uterine massage
Reduced risks of maternal blood loss
MANAGEMENT OF THIRD STAGEOF LABOR
Urinary bladder should be emptied in all cases
Administration of a uterotonic agent is recommended
during the third stage to reduce maternal blood loss
Uterotonic agents should not be given until after
delivery of the anterior fetal shoulder toensure that
shoulder dystocia is notexacerbated.
The clinician should also be certain that there is no
undiagnosed and undelivered twin
DRUGS USED FOR ACTIVEMANAGEMENT
Methergine
Oxytocin
There are insufficient data to determinewhether
administration of the uterotonic agent is more
effective
If it is given after delivery of the anterior shoulderbut
before separation of the placenta
Or immediately upon expulsion of theplacenta
Maneuver to facilitate placentaldelivery
Brandt-Andrews maneuver
Controlled cord traction (recommended by WHO)
Fundal Pressure
Controlled cord traction
recommended by
WHO
After birth of baby, the cord stops pulsating and is cut, severing
the baby from the mother. Follow the cord and grasps it at the
vaginal opening, taking up any cord slack, pulling it straight out
the vaginalopening
A large ring forceps is clamped onto the cord at the
entrance to the vagina and let it hang down by its own
weight
Checking for placental separation and release along with
uterine tone and contraction by placing a hand on the
uterus. Do not massage the uterus. Allow it to contract
on its own. When the uterus contracts, it will form a
hard globular ball which rises slightly under your hand.
Tell the mother to let you know when she begins to have
contractions again
Do not massage
the uterus
Checking placental separation and release from the
uterus by placing a hand on the uterus and using
the other hand for cord traction. Uterine firmness is
noted.
Cord traction is applied, using the ring forceps to obtain a firm
hold (the cord is very slippery), taunt traction is done, pulling
gently but firmly away from the vagina. The mother should be
having contractions at this point. There is usually a little gush
of blood as the placenta begins to pull away from the uterine
wall. Placenta separation maybe apparent bythe increasing
cord length between the forceps and the vaginal opening.
Placenta Delivery: Controlled cord traction. Have the
mother begin pushing with her contractions. If there
is a gush of blood and lengthening of the cord, have
the mother push whetheror not there is a contraction.
Placenta Delivery: Using one hand to apply suprapubic pressure against the
fundus of the uterus with your cupped hand, and your thumb placed just
above the pubic bone to keep the uterus from entering the pelvis and
causing spurious cord lengthening or other false evidence of separation, or
even inverting the uterus. Provide some steady cord traction to not whether
there is a sense of "give" as the placenta moves into the vagina and the cord
lengthens, or conversely, does not progress, in which case cease your
maneuvers and wait. If you are uncertain whether the placenta has actually
separated, you may follow the cord with your hand in the vagina, up to the
cervix, to determine if the placenta is trapped in the cervical os, or whether
the cord disappears into the uterus.
There is no hurry to deliver theplacenta
It is normal and safe, if there is no bleeding, to wait up
to an hour, checking for separation periodically
The placenta has been known to stay attached to the
uterine wall for days after a delivery. If this occurs
because there is acreta, this is the safe state until the
problem can be evaluated more completely.
In the absence of heavy bleeding
If the placenta has separated without your knowledge
and it is not delivered , then the uterus may be silently
filling with blood.
This is another reason for keeping your abdominal
hand over the uterus at all times until the delivery of
the placenta is imminent at theintroitus
Placenta Delivery : Use maternal efforts to deliver the placenta, assisted by the
following maneuvers, as needed, when you believe the separation has occurred.
Maintain your abdominal hand over the uterus, using your flattened fingers just
above the pubic bone to aid the placenta as it exits the cervical os into the
vagina. Instead of pressure with flattened fingers, the Brandt Andrews maneuver
mayalso be used, but this is more uncomfortable for the mother. Place your
fingers around the ring forceps at the point where the cord is attached, and
apply steady cord traction with a downward motion. The Upward Placental Lift:
then upward along the curve of Carus as the placenta traverses the vagina to
the introitus. When the placenta is visible at the introitus, lift it partially
through with the hand holding the ring forceps.
Placenta Delivery: Remove your other hand from the abdomen
and letthe placenta fall into your hands. At this point, drop the
cord and ring forceps.
Encompass the placenta using both hands to support it during
delivery,
making sure the membranes do nottear.
Placenta Delivery: Using an Up-Down-
Rotation method to bring it through the
os.
Placenta Delivery: Once the placenta is delivered,
continue to rotate it and the membranes to form a
thicker cord of membranes help the membranes
release intact without tearing or shredding.
Placenta Delivery: Grasping the membranes with the ring forceps
to help in
delivery and to aid in making a thicker cord of membranes.
Placenta Delivery of the Membranes: Rotating the ring
forceps to "tease" the membranes loose from the uterine
lining without shredding them by a slight up and down
movement. NOTE: Slow controlled delivery is necessary to
avoid tearing of the cord or membranes.
Placenta Delivery Cleanup: Once the placenta is out,
massage the belly once or twice above the uterus to get the
uterus to contract and form a grapefruit size firm ball
under your hand. Wipe out the blood from the introitus
(vaginal opening) after the delivery of the placenta to
determine if you have additional bleeding.
Rapid infusion of intravenous oxytocin
(10units) upon delivery of the
anterior shoulder (to limit the risk of
shoulderdystocia).
After delivery of the baby and when
signs of placental separationareevident,
we employ the Brandt maneuver andput
gentle traction on the umbilical cord to
facilitate delivery of the placenta.
Perform manual uterine massage and
continue the oxytocin infusion after
delivery of the placenta

Fundal pressure maneuver
The fundus is pushed downward and backward
after placing 4 fingers behind the fundus and the
thumb in front using the uterus as a sort of piston.
Pressure must be given only when the uterus
becomes hard.
Uterus is massaged to make it hard, which
facilitates expulsion of retained clots if any.
