Although childbirth has long ceased to present a
serious physical challenge to healthy to women in
western society –the emotional impact of labour
remains a matter of common concern

Diagnosis of Labour
The diagnosis of labour is the single most important
item in the conduct of labour.
If the initial diagnosis is wrong, all subsequent
management is likely to be wrong too.
Midwife is the only person who makes this
important diagnosis in our hospital
Preparation for Labour
Preparation
takes away
the fear of the
unknown.
Women are
familiar with
terminology and
labour records.

In Labour
80% of women admitted to the labour ward
have a cervical dilatation of < 3cms
Diagnosis of Labour
A woman who is admitted with painful uterine
contractions supported by either a show or
spontaneous rupture of the membranes, and on
vaginal examination her cervix is fully effaced is
deemed in labour, and retained in the labour
ward and therefore committed to delivery which
is anticipated within 12 hours.
Effaced cervix is
confirmation of
diagnosis of labour
irrespective of
dilatation
Diagnosis of Labour
Dilatation of the cervix represents the sole
conclusive evidence of labour.
Effacement is the feature which serves to
distinguish between the cervix which passively
admits a finger tip and the cervix which is
actively dilated to the extent of 1cm in labour.

Effacement
of the cervix is the key to
the diagnosis of labour
and it’s graphic analysis
and that is when the
partogram is started
Dilatation on diagnosis
80% < 3cm
Spontaneously labouring
nulliparous women with a
single cephalic pregnancy
at 37 weeks or greater
Philosophy
A clear pattern of dilation
should emerge and
determined clinically
within the first 3-4 hours
of labour
1 cm an hour is taken as
normal progress
Spontaneously labouring
nulliparous single cephalic
women at term
4 hours is too long to wait between
examinations to make the diagnosis
of inefficient uterine action
Efficient uterine action and normal
progress only be confirmed by
doing vaginal examinations 2 hourly
before oxytocin is started.
Average number of vaginal
examinations in total is 3.7
Epidural rate 50%.
90% of epidurals given within 4 hrs
CS rate 7% and not increased
significantly over the last 25 years
• Level of mutual confidence must be
present between midwives and doctors
• Clear chain of command
• Mutual Respect
• Co-ordinator/Midwife in charge has a
vital role to play
