• Fetal heart rate
• Character of liquor
• Uterine contraction
• Pain relief (e.g. pethidine)
• BP, Pulse, Temperature
• Urine – albumin, glucose, acetone
• Urine output

Cervical dilatationCervical dilatation
It is the surest way to assess progress of labour
latent phaselatent phase
Starts from onset of labour until the cervix reaches 3
lasts 8 hours or less
Contractions at least 2/10 min contractions
each lasting < 20 seconds
Active phase :Active phase :
The cervix should dilate at a rate of 1 cm / hour
Contractions at least 3 / 10 min each lasting < 40
Alert line ( health facility line )Alert line ( health facility line )
The alert line drawn from 3 cm dilatation
represents the rate of dilatation of 1 cm / hour
Moving to the right or the alert line means
referral to hospital for extra care
Action line ( hospital line )Action line ( hospital line )
The action line is drawn 4 hour to the right
of the alert line and parallel to it
This is the critical line at which specific
management decisions must be made at the
When labor goes from latent to active phase , plotting of
the dilatation is immediately transferred from the latent
phase area to the alert line

Cesarean section is indicated in the presence

Abnormalities of the Critical Factors:
Psychology of birthPsychology of birth
The progress of labor and birth can be
adversely affected maternal fear and tension.
Norepinephrine and epinephrine may stimulate
both alpha and beta receptors of the
myometrium and interfere with the rhythmic
nature of labor.
Anxiety can also increase pain perception and
lead to an increased need for analgesia &

Therapeutic InterventionsTherapeutic Interventions
– Nipple Stimulation --release of endogenous Pitocin
– Enema--warmth of enema may stimulate contractions
– Amniotomy--artificial rupture of the membranes
– Augmentation of labor with Pitocin
Amniotomy is the artificial rupture of the amniotic
sac with a tool called the amniohook
# 1-Check the fetal heart tones
– Assess color, odor, amount
– Provide with perineal care
– Monitor contractions
– Check temperature every 2 hours
Hypertonic and uncoordinatedHypertonic and uncoordinated
Frequent intense contraction
Cephalopelvic Disportion (CPD)Cephalopelvic Disportion (CPD)
– Large baby or small pelvis
– Usually diagnosed when there is an arrest in descent
– Station remains the same does not descend
– Usually do a cesarean delivery if cause is pelvis
– Utilize other measures such as forceps, vacuum
Pelvi- Latin word pelvis (basin)
Metron - Greek word for measure
Pelvimetry means to measure the pelvis.
Three level of bony pelvisThree level of bony pelvis
Measuring diagonal conjugate
Insert two fingers into the vagina until they reach the
The distance from the sacral promontory to the exterior
portion of the symphysis is the diagonal conjugate and
should be greater than 11.5 cm.
Unengaged fetal head
• Feel the ischial spines for their relative
prominence or flatness.
• Ischial prominence narrows the transverse
diameter of the pelvis.
• Feel the pelvic sidewalls to determine
whether they are parallel (OK), diverging
(even better), or converging (bad).
• Narrow sacrosciatic notch
Measure the bony outlet by pressing your
closed fist against the perineum.
Greater than 8 cm bituberous ( or transverse
outlet) is considered normal.
Narrow pubic arch<90
Hinweis der Redaktion
Successful completion of a pregnancy requires the harmonious functioning of the critical factors in labor. When this does not occur, it is noted as a dysfunctional labor.
d. What interventions might the nurse implement?
Define the term cephalopelvic disproportion (CPD): a. What are the causes of CPD? b. What are the symptoms for CPD in the laboring woman? c. What is the medical treatment for CPD?
