repeated, forceful uterine contractions.
Uterine contractions supply the power that
makes birth possible. Contractions cause the

It starts from the onset of true labor pain, and ends with
the full dilatation of the cervix. Its average duration is 12
hrs. in primigravidae and 6 hrs in multiparae1.
FIRST STAGE comprises of 3 phases
phase : is prior to active first stage of labor
and may last 6-8 hrs. in first time mothers when the
cervix dilates from 0 cm to 3-4 cm dilated and
cervical canal shortens from 3 cm to less then 0.5
phase : is the time when cervix undergoes
more rapid dilatation. This begins when the cervix
is 3-4 cm dilated2.
phase : is the stage of labor when the
cervix is around 8cm dilated until it is fully dilated2.
second stage is that of expulsion of
the fetus. It begins when the cervix is fully
dilated and the women feels urge to expel
the baby. It is complete when baby is
It has got two phases :
Propulsive phase : starts from full dilatation
up to the descent of the presenting part to
the pelvic floor.
Expulsive phase : is distinguished by maternal
bearing down efforts and ends with the delivery
of baby. Its average duration is 2 hours in
primigravida and 30 min utes in muliparae.
third stage is that of separation and
expulsion of placenta and membranes ; it
also involves control of bleeding. It lasts
from the birth of the baby until the placenta
and membranes have been expelled2.

Each uterine contraction starts in the fundus
near one of the cornua and spreads across
and downwards. contraction lasts longest in
the fundus where it is also more intense and
contraction fades from all parts together.
Polarity is the term used to describe the
neuromuscular hormony that prevails
between the two poles or segments of the
uterus through out the labor.
polarity disorganized = labor inhibited
Contraction is the

the opening of the cervix, the entrance to

Cervical dilation may occur naturally, or may
be induced by surgical or medical means .
General guidelines for cervical dilation:
Latent phase: 0-3 centimeters

pregnancy, the os (opening) of the
cervix is blocked by a thick plug of mucus to
prevent bacteria from entering the uterus.
During dilation, this plug is loosened. It may
come out as one piece, or as thick mucus
discharge from the vagina. When this
occurs, it is an indication that the cervix is
beginning to dilate.
Bloody show : is another indication that the
cervix is dilating. Bloody show usually comes
along with the mucus plug, and may continue
throughout labor, making the mucus tinged
pink, red or brown.
The sac of amniotic fluid is described as having
two sections – the forewaters (in front of baby’s
head) and the hind waters (behind baby’s head).
During labor forewaters are formed as the lower
segment of the uterus stretches and the chorion (the
external membrane) detaches from it4.
The well flexed baby’s head fits into the cervix
and cuts off the fluid in front of the head
(forewaters) from the fluid behind (hind waters)4.
from contractions cause the
forewaters to bulge downwards into the
dilating cervix and eventually through into
the vagina. This protects the forewaters from
the high pressure applied to the hind waters
during a contraction and keeps the
membranes intact 4.
forewaters transmit pressure evenly over
the cervix which aids further dilatation 4 .
a contraction the pressure is
equalised throughout the fluid rather than
directly squeezing the baby, placenta and

membranes to rupture spontaneously is at

several consideration govern the choice of
position during the first stage of labor, of these
the most important is that of maternal
preference. In early labor, ambulation can be
encouraged and during a contraction the woman
often finds it comforting to lean forward,

lateral position will be the best as this avoids
compression of the inferior venacava and

upright and leaning
forward reduces this pressure
while allowing your baby’s head to
constantly bear down on your
cervix. The result? Dilation tends
to occur more quickly.
Advice prior to admission : the women’s need in
labor is for energy and it is carbohydrates which
provide. She should choose food that are light
and easily digested such as bread and
butter, fluids may be taken freely, although fizzy
and very sweet drinks may induce vomiting.
Intake in early labor : in some centers, no food is
permitted after labor is established, on the basis
that anesthesia could be needed.
Policies in advance labor : most obstetric units
withhold food in advanced labor. Some also
discourage drinking but allow the women to have
sips of water to keep her mouth comfortable.
Bladder care :
The woman should be encouraged to empty
her bladder every 1-2 hrs during labor.
The quantity of urine passed should be
If the bladder remains full, the bladder neck
can become nipped between the fetal head
and the symphysis pubis. This may give rise
to bruising which can slough during the
perineum leaving a vesico-vaginal fistula.
Pulse rate : A steady pulse rate is an
indication that the women is in good
condition. If the rate increases mare than

with some sedative properties. These include
pethidine, morphine, naloxone, pentazocine.

Uterine actions :
contractions becomes stronger and longer
but may be less frequent affording mother
and fetus a recovery period during the
contractions and retractions of the upper
uterine segment while the lower segment
and cervix passively dilate and thin. The
membrane often rupture spontaneously at
the onset of second stage.
The consequent drainage of liquor allows the hard
, round fetal head to be directly applied to the
vaginal tissues and aid distension.
Fetal axis pressure increases flexion of the head
which results in smaller presenting
diameters, more rapid progress and less trauma to
both mother and fetus
The nature of the contraction changes. They
become more expulsive as pressure is exerted on
the rectum and pelvic floor.
2) Soft tissue replacement :
As the fetal head descends, the soft tissue of the
pelvic become displaced. Anteriorly the bladder
is pushed upwards in to the abdomen where it is
at less risk of injury during descent .
Posteriorly the rectum becomes flattened in to
the sacral curve and the pressure of the
advancing head expels any residual fecal matter.
The fetal head become visible at the vulva,
advancing with each contraction and receding

for a women to feel a strong desire to push

passes the pelvic inlet, the head is said to
be engaged in the pelvic inlet .
In most nulliparous pregnancies this occurs
before the onset of active labor because the
firmer abdominal muscles direct the
presenting part into the pelvis.
In multiparous pregnancies, in which the
abdominal musculature is more relaxed, the
head often remains freely movable above the
pelvic brim until labor is established.
: The head usually engages in
the pelvis in a synclitic position, one that is
parallel to the anteroposterior plane of the
pelvis. Frequently asynclitism occurs (the
head is deflected anteriorly or posteriorly in
the pelvis), which can facilitate descent
because the head is being positioned to
accommodate to the pelvic cavity. However,
extreme asynclitism can cause cephalopelvic
disproportion, even in a normal-size pelvis,
because the head is positioned so that it
