Contraction
Patterns of
Labour
How do they influence our
management of care to
support the normal process
of labour?
Know the
normal
Work with the abnormal to
make it normal
In the past quarter century,
advances in medical technology
have been accompanied by an
increase in
intervention-intensive labour and
birth
( Hamilton, Martin, & Ventura, 2006 ).
Nature ’ s simple
plan for birth has been replaced by a
maternity care
system that routinely interferes with the
normal physiological
process and in doing so introduces
unnecessary
risks for mother and baby.
Women no longer have confi -
dence in their ability to give birth without
technologic intervention.
The physiological mechanisms
of labour and childbirth
are NOT completely understood.
Intrinsic factors within the uterine muscle
affect contractions and progressive
cervical dilation. Thus,
spontaneous onset of term labour
signifies the baby’s
readiness to be born as well as the
mother ’s physiological
receptiveness to the process.
Don’t pick a plum before it is
ripe
The Cervix needs to be soft
With good observation applied
anatomy and physiology, and
critical thinking during the birthing
process it is possible to achieve
normal vaginal birth.
 One of my failings
as a midwife is my
inability to assess
the strength and
effectiveness of
uterine
contractions. I am
often asked
 How strong are her
contractions?
 How effective are
her contractions
Can we measure
the effectiveness
of contractions?
Failure to understand labour
 Early interventions
 Pain relief
 Epidurals
 Artificial rupture of membranes
 Oxytocinon/Syntocinon/Pitocin
 C section
There are Many theories
 Friedmann defined the three stages of
labour
 Latent and active
 Second stage
 Third stage
These theories do not have any
application to anatomy and
physiology or to the contraction
patterns of labour
they merely measure time
frames.
Failure to diagnose labour
 In 2013, researchers published a report of 38,484
first-time C-sections that occurred among a
national sample of women. The overall C-section
rate among first-time mothers was 30.8%. More
than 1 in 3 (35%) of these C-Sections were due to
a diagnosis of “failure to progress,” or slow
progress in labour. This means that 10%, or 1 in 10,
of all first-time mothers in the U.S. had a C- Section
for failure to progress during the years 2002-2008
(Boyle, Reddy et al. 2013).
 More than 4 in 10 of these women who had C-
sections for failure to progress had not even reached
5 cm dilation before they were taken to surgery. This
means that many of these women were still in very
early labour when they were told that they weren’t
dilating fast enough (Boyle, Reddy et al. 2013).
Progress and Time
 A substantial number of women have
unplanned C- Sections for failure to progress
during a medical induction. In a 2010 study
that included 233,844 new-borns born
between 2002 and 2008, researchers found
that about half of all induced women who
had C-sections for failure to progress had not
reached 6 cm yet (53%)– indicating that they
were still in very early labour when their
inductions were labelled as “failed”

 Observe contraction

 Apply anatomy and
physiology to the six
stages of labour
 Know the birthing
hormones and
applied anatomy
and physiology
 Look at the bigger

Labour contractions can
increase and decrease in
frequency following admission
to hospital. This may be
associated with dilatation and
posture rather than anxiety

Are there 6 stages of Labour?
 Descent
 Effacement
 Active
 Transition
 Second Stage
 Third stage
Descent
• The transverse
muscles of the
uterus contract to
facilitate the
descent of the
head into the
pelvis
Oestrogen levels begin
to fall and go over a
few weeks
Descent
The transverse muscles continue
to assist the head to descend into
the pelvis.
At some stage prostaglandin is
released.
The cervix softens.
The longitudinal muscle begins to
contract from the fundus to pull
back the cervix over the head.
This gives a picture of variable
contractions.
The rounded contractions giving
height as the longitudinal muscles
do their job.
 Short and sharp contractions as
the head continues to descend
into the pelvis
Effacement and
early dilation
Effacement
Regular coordinated
contractions as oxytocin is
released
The longitudinal muscles
pull s the cervix back over
the baby’s head
Usually greater than 5cm
on admission
Can stop for 1-2 hours prior
to transition
Endorphins are released to
assist with maternal pain
management.
Active
Phase
Dilation
Contraction patterns may
change
 The body knows what to do.
 If the baby is in posterior position there will be more
descent patterns of contractions with back pain.
 Babies sometimes rotate in and out of posterior
position as the baby corkscrews down into the pelvis
 If baby is moving from ROA to LOA.
 The mother needs to move position to help her baby
turn.
 Augmentation may drive down the Op baby and
cause obstruction if forced.
 In my experience forcing a baby down in the OP
position may weaken the uterus.
 Can’t do it
 Won’t do it
 Cut it out
 Give me an
epidural
 Get me out of

 It’s all your fault

around 7-8cm

Role
To support the

process of

My intervention rate was much
higher.
I did not understand the normal physiological process of labour
I did not know how to manage the contraction patterns of labour
or manage care applied to the 5P’s with a midwifery perspective
I did not know how to educate and empower my women
I was not strong enough to provide tough love
 In the beginning I spent many of 16 hours with
women on delivery unit.
 Now I can drink tea. Usually only two to fours hours
on Delivery unit.
Thanks to the continuity of care,
reflection of practice, use of
complementary therapies, my vaginal
birth rate is around 95%. My epidural
rate is around 4%
“Very few women spend a long time in hospital and
have faith in childbirth. When midwives learn from
reflection, share knowledge and work as a team
the future for our families will be sound” Irene Chain

 Support the natural process
 Tough love where necessary
 Better antenatal education
 Ambient Rooms and acceptance for women who
have little support
 Support your colleagues/and better

 On call sleep room for health professionals with

 Empower women to take charge
 No CTG monitoring for low risk women
