Broad objective
By the end of the lesson, the
learners will be able to manage a
mothers in abnormal labor
Sunday, March 2, 2025 2ABNORMAL LABOR: BY PAUL NYONGESA

Specific objectives
1.To describe obstructed labor
2.Prolonged labour
3.To describe occipitoposterior
position
4.To describe mal-presentations
Sunday, March 2, 2025 3ABNORMAL LABOR: BY PAUL NYONGESA

Factors influencing good
prognosis of labour
Strength of the uterine contractions
Flexion of the head
Degree of moulding of the foetal head, that is,
reduced engaging diameters
The giving of pelvic joints. In pregnancy, the
joints of the pelvis are relaxed and separate
by half to one centimetre
Maternal courage
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 4

Factors influencing poor
prognosis
Early rupture of membrane which may be
accompanied by prolapsed cord
Poor moulding of the head
Maternal or foetal distress which will
necessitate intervention on trial of vaginal
delivery
Remember: Do not hesitate to terminate
the trial of labour when there is foetal or
maternal distress.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 5

Maternal Injuries
Most maternal injuries occur during the
second stage of labour but the diagnosis is made
in the third stage after the delivery of the baby.
The most common ones are described below.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 6

Perineal Tears
The perineum is the region between the vaginal opening
and the anus.
The perineum may get injured when there is overstretching
or rapid stretching during the delivery of the baby.
An inelastic perineum due to the presence of a scar can also
lead to a perineal tear.
causes of overstretching of the perineum leading to
perineal tear are:
A big baby - usually babies more than 4000 grams or 9
ounces are considered big.
Malpresentation of the baby like occipitoposterior position
or face presentation.
Average sized baby with a narrow maternal vaginal outlet
Forceps delivery or other instrumental deliveries
Shoulder Dystocia
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 7

Degrees of Perineal Tears
There are three degrees of perineal tear.
First Degree perineal tear: This is only a mild degree
of laceration or tear of the skin at the edge of the
vaginal opening. The lower part of the vagina as well
as the perineal skin may be torn but the major
muscles of this region are not affected.
Second degree perineal tear: This involves rupture
of the muscles of the perineum with deep tears in the
vaginal wall. The tear may extend right up to the anus,
but does not involve the anal sphincter.
Third degree perineal tear: In a complete perineal
tear, the tear extends from the vaginal opening
through the posterior vaginal wall and the perineal
muscles up to the anus with injuries to the external
anal sphincter. The anal or the rectal canal may or
may not be involved.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 8

Management of Perineal Tears
Prevention is the best management. The
second stage of labour should be properly conducted. An
episiotomy should be performed wherever deemed
necessary to prevent tear of the perineum.
Immediate Repair: A first degree or second degree tear
should be immediately repaired, preferably within the
first 24 hours.
Delayed Repair: If the tear is diagnosed after 24 hours,
then the woman is given antibiotics and the wound
dressed so that infection , if any, is controlled. Then the
tear is repaired.
Third Degree tear: A third degree tear is always
repaired after immediately after the delivery of the baby
to allow the tissues to regain the pre-pregnant state.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 9

Vaginal Tears
Vaginal Tears can occur at any part of the vaginal wall,
but are seen mostly at the junction between the lateral
and posterior walls. These tears may be superficial with
only minor lacerations of the vaginal mucosa. But,
sometimes the tears may be deep enough to expose the
inner muscles.
Vaginal tears can also occur at the region around the
urethra - the opening through which urine comes out.
These are then called ' Paraurethral tears'. The
problem with these type of tears is that there may be
profuse bleeding from even a small tear since the region
has a large blood supply.
Treatment / Management of vaginal Tears
The vagina should always be examined under proper
light immediately after the delivery of the baby for any
such tears. All tears should be repaired immediately.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 10

Cervical Tears
Minor tears of the cervix are very common
during delivery, especially in a woman who
is delivering her first child.
But sometimes, major lacerations which can
cause severe bleeding
Cervical tears are the commonest form of
traumatic post partum hemorrhage.
Cervical tears are commonest at the lateral
angle, between the anterior and posterior lips
of the cervix.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 11

Causes of Cervical Tears
Delivery through an undilated cervix
whether spontaneously, or by forceps.
Precipitate labour.
Rigid cervix due to previous operations like
the LEEP procedure, conisation, or cervical
amputation.
Very vascular cervix as can occur in low level
placenta previa
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 12

Management
The aim of treatment is to control bleeding as
early as possible by repairing the tear.
Minor lacerations without active bleeding
does not require to be repaired - they heal
spontaneously with no ill effects.
Major cervical lacerations or tears need to be
repaired in the Operating theater under
anesthesia, good light and proper exposure of
the tear.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 13

Vulval Hematoma
Collection of blood anywhere in the vulval
region is called vulval hematoma.
 Although vulval haematomas can also occur
after an injury due to any cause, it is
commonly seen after the vaginal delivery of a
baby.
A Vulval hematoma can occur either
spontaneously or after improper repair of an
episiotomy wound.
Blood from a rupture of the deep veins of this
region collects in a closed space with no
opening for it to drain out.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 14

Signs and Symptoms
A steadily increasing swelling to one side of
the vagina.
The swelling is tense and tender to the touch.
The woman complains of severe pain, more
so on sitting down.
There may be difficulty in passing urine if the
swelling presses on the urethra.
The bleeding can be severe enough to cause
the patient to go into shock.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 15

Management
The aim of treatment is to ligate the bleeding
blood vessels as early as possible and support
the patient with IV drips and medicines so
that she does not go into shock.
An incision is made at the most distended
point of the hematoma.
The incision is then deepened and the blood
clots scooped out.
The bleeding vessels are identified and tied
up.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 16

Management cont..
The incision is closed by applying different
layers of stitches.
A drain may be put in the wound for 24 hours
to allow any oozing blood to flow out.
Proper antibiotics are prescribed and the
patient kept under close observation.
Blood transfusion is given if necessary.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 17

PROLONGED LABOUR
Labor is said to be prolonged when the combined
duration of both the first stage and second stages
of labor is more than 18 hours.
It is more common in a first pregnancy and in
women over the age of 35 years
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 18

Complications of labor cont.
Abnormal labor arises as result of
factors causing obstructed and
prolonged labor
i. Obstructed labour
There is no advancement of the
presenting part despite strong
uterine contractions
Sunday, March 2, 2025 19ABNORMAL LABOR: BY PAUL NYONGESA

Complications of labour cont.
Obstructed labour occurs mainly at
the pelvic brim
There may be abnormality of the
passage and the passenger
ii. Prolonged labour
In prolonged labour “power” is the
main cause
Sunday, March 2, 2025 20ABNORMAL LABOR: BY PAUL NYONGESA

Causes
Causes of Prolonged First Stage of Labour
Poor uterine contractions, leading to the cervix dilating slowly
or not at all
Pelvic abnormalities (passage), where contracted pelvis and
tumours of the pelvis cause poor progress in labour
The foetus (passenger) is big foetus (macrosomia)
Malposition
Malpresentation
Psychological causes, for instance; tension and fear of the
unknown tend to prolong labour, most commonly in women
who are primigravidae
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 21

Causes
Causes of Prolonged Second Stage of Labour
Secondary hypotonic contractions
Poor maternal effort, which could be due to fear, exhaustion or
lack of sensation due to epidural block, which may inhibit the
woman’s ability to bear down
A rigid perineum
Reduced pelvic outlet, as in the android pelvis,
Macrosomia
Malposition
Malpresentation, leading to a large presenting diameter,
accounting for the delay
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 22

Causes of Prolonged Labor
Problems with Uterine Contraction: The
uterine muscle may fail to contract properly
when it is grossly distended as in twin
pregnancy and polyhydramnios . Presence of
tumors like fibroids in the uterine
musculature can also affect uterine
contraction.
Use of Sedatives and Anesthesia: Excessive
use of painkillers or anesthesia can cause
inefficient uterine action.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 23

Causes of Prolonged Labor
They can also decrease the pain of normal labour
and prevent voluntary effort by the mother to deliver
the baby during the second stage of labor.
Cervical dystocia or stenosis: The term cervical
dystocia is used when the cervix fails to dilate
properly and remains at the same position for more
than 2 hours. The cervix may fail to dilate when it is
fibrosed due to previous operations like cone biopsy
or due to the presence of tumors like cervical polyps
and fibroids.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 24

Signs and Symptoms of
Prolonged Labour
Labor extends for more than 18 hours.
Patient looks exhausted and distressed. Dehydration may be
present. Mouth may be dry due to prolonged mouth breathing.
Pain may be more on the back radiating to the thighs rather
than inside the abdomen. This is due to pressure over the
muscles and ligaments.
Labor pains may initially be severe, frequent and prolonged but
later decrease and become very mild as the muscles become
fatigued.
Pulse rate is often high.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 25

Signs and Symptoms of
Prolonged Labour
The large intestines are dilated and can be palpated along both
sides of the uterus as large, thick structures filled with air. They
give off the hollow sound of drums on tapping.
The uterus is tender on palpation and does not relax fully
between contractions.
Ketosis may develop due to prolonged starvation.
Fetal distress may develop.
Membranes may or may not rupture early. In early rupture,
there is a risk of infection of the uterine contents if proper
antibiotics are not prescribed.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 26

Diagnosis of Prolonged Labour
Proper history of labour including type, duration and frequency
of uterine contractions
Examination of the mother, checking for general appearance,
whether distressed or exhausted                       
Check the temperature and pulse as an increase of either of
them would be significant
Urinalysis, where concentrated urine suggests fluid imbalance
and dehydration. Check for ketones in the urine, the presence
of this must be corrected at once
It is important to identify the cause in order to decide the
course of action.

Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 28

Risks of Prolonged Labour
Fetal Risks:
Fetal Distress due to decreased oxygen reaching the fetus.
Intracranial hemorrhage or bleeding inside the fetal head.
Increased chances of operative delivery like Cesarian sections.
Longterm risks of the baby developing cerebral palsy.
Maternal Risks:
Intrauterine infections
Trauma and injuries in the maternal birth passage (See Maternal
Injuries.)
Postpartum hemorrhage.
Postpartum infection.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 29

Management / Treatment of
Prolonged Labour
With the discovery of various drugs capable of
accelerating labour, prolonged labour is a rare
nowadays.
After 3cms of dilation, the cervix should dilate at the
rate of 1cm per hour. If there is lack of dilation for a
reasonable period of time, then an oxytocin drip is
started.
Drugs like buscopan causes softening of tissues in the
cervix.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 30

Management / Treatment of
Prolonged Labour
If the cervix fails to dilate in spite of adequate uterine
contraction, epidosin or buscopan can be safely given to cause
softening of the cervix.
Intensive clinical monitoring should be done, recording the
pulse, BP, fetal heart sound (FHS) and dilation of the cervix at
intervals of two hours. FHS should be checked even more
frequently if necessary.
If, in spite of the above procedures, labour fails to get
accelerated or if foetal distress develops, Cesarian Section
should be done.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 31

ABNORMAL UTERINE ACTION
Abnormal uterine action is a dysfunction of uterine
muscles due to neuromuscular disharmony. Some
types of abnormal uterine action include:
Hypotonic uterine action
In-co-ordinate uterine action, including hypertonic
lower uterine segment, constriction ring dystocia,
colicky uterus and spurious labour
Cervical dystocia
Precipitate labour
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 52

Hypotonic Uterine Action
This is poor tone in the uterine muscle fibres
which results from weak/short contractions.
The contractions are infrequent and cause less
pain.
The uterus may be indented at the height of a
contraction. Both mother and baby are affected
by the contractions.
The effects of weak contractions bring about
very slow or no cervical dilatation. This results
in prolonged labour.
There are two types of hypotonia; primary and
secondary uterine inertia also respectively
known as primary and secondary hypotonia.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 53

Types of Hypotonia
Primary hypotonia starts at the onset of
labour. The cause is unknown and it is
common in primigravida.
Secondary hypotonia occurs when labour
has already been established. The uterus is
exhausted and contractions slow down, due
to:
Retained second twin
Cephalopelvic disproportion
Malpresentation or malposition
Effect after epidural anaesthesia
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 54

Incoordinate Uterine Action
In cases of incoordinate uterine action, there
is alteration in the polarity of the uterus with
an increase in the resting tone.
The uterus is very irritable. The contractions
are strong, painful and erratic but in spite of
strong contractions, the cervix dilates slowly.
Clinically, the patient experiences a lot of
pain both before and after contraction.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 55

Incoordinate Uterine Action
She is exhausted and bears down early due to
severe backache. This may lead to retention
of urine.
Foetal hypoxia occurs due to the hypertonic
state of uterus, which interferes with the
placental circulation.
On Vaginal Examination (VE) the cervix is
noted to dilate slowly despite frequent painful
contractions.
The cervix is tight, unyielding and
oedematous since the mother bears down
with each contraction.
There are four varieties of Incoordinate
uterine action, which will be explored:  
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 56

Incoordinate Uterine Action
There are four types of incoordinate uterine action
Hypertonic Lower Uterine Segment
Colicky Uterus
Constriction Ring Dystocia
Spurious Labour
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 57

Hypertonic Lower Uterine
Segment
In this case, the lower uterine segment is
hypertonic.
There is loss of polarity and intermittent
abdominal pains.
The pains occur before and persist long after a
uterine contraction.
 The cervix fails to dilate.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 58

Colicky Uterus
The upper uterine segment contracts strongly and
spasmodically.
As a result of the different parts of the uterus
contracting differently the cervical dilatation is
ineffective.
There may be reduced placental blood flow leading
to foetal distress.
There is intense crump-like pain, contractions are
not effective and the uterus is tender.
The mother may not experience severe backache.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 59

Spurious Labour
Spurious labour is a condition where
contractions occur before the onset of labour,
which are painful and are accompanied by
backache.
Giving pethidine or morphine 1ml to relax the
uterine contractions can abolish them.
This differentiates it with true labour.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 60

Precipitate Labour
Def:
 strong and frequent contractions from the
onset of labour, resulting in an abnormally
rapid progress of labour and delivery may
occur within an hour from the onset of
labour. There are several types of
complications which can occur.  
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 61

Precipitate Labour
Over-Stimulation of the Uterus
This may occur as a result of excessive use of
syntocinon or prostaglandin, which may cause
tetanic contractions with inadequate periods of
relaxation.
Complications of over-stimulation of the uterus
include
foetal hypoxia.
If uterine spasms that reduce the transfer from the
placenta of foetal oxygen are not treated, foetal death
may occur.
precipitate labour and
rupture of uterus in cases of disproportion.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 62

Precipitate Labour
Methods of management should include the
following:
Stop the administration of syntocinon or
prostaglandin
at once
In case of tonic contractions, the patient should be
given
two puffs of ventolin inhaler
If there is foetal distress, give I.V normal saline and
oxygen by mask 
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 63

Precipitate Labour
Tonic Contractions
This is where the contractions are excessively longer, stronger
and more frequent. This results in almost continuous
contractions with short periods of relaxation.
Tonic contractions are caused by cephalopelvic disproportion.
The uterus attempts to overcome the obstruction and so it
increases its strength and frequency.
The condition is common in primigravida.
Possible complications of tonic contractions include
rupture of the uterus and
foetal death due to hypoxia
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 64

Precipitate Labour
Management of Tonic contractions
If the patient is on syntocinon drip, it should be
discontinued and the doctor informed.
The vital signs, including observations of pulse &
blood pressure, should be monitored carefully.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 65

Precipitate Labour
There are several factors, which predispose to
abnormal uterine action, these include:
elderly primigravida
Primigravida
Cephalopelvic disproportion
Malpresentation
Post maturity
Multiple pregnancy
Early rupture of membranes
Emotional tension of the patient
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 66

Precipitate Labour
Maternal complications include
cervical and perennial lacerations.
The uterus may fail to contract during the
third stage of labour, leading to a retained
placenta.
 Post partum haemorrhage
Acute uterine inversion
Shock and collapse may occur due to sudden
relief of pressure.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 67

Precipitate Labour
Foetal complications include
foetal hypoxia, which may occur as a result of
frequent and strong contractions.
 Rapid moulding may result in intracranial
pressure and, during delivery, this may lead
to intracranial haemorrhage.
Asphyxia may occur due to rapid expulsion
of the baby’s unmoulded head. 
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 68

Precipitate Labour
Remember: Precipitate labour tends to recur.
Therefore, with future pregnancies the
mother needs to be admitted early
into hospital for safe delivery.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 69

Cervical Dystocia
Cervical dystocia can be divided into
two classes; primary and secondary.
Primary cervical dystocia
Secondary cervical dystocia
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 70

Primary Cervical Dystocia
Primary Cervical Dystocia: the uterine
contractions are normal and the presenting
part is low down in the pelvis but the cervix
fails to dilate.
The delay is due to the formation of a
cartilaginous ring round the cervix.
This condition occurs mainly in primigravida
whereby the first stage is prolonged and
there is severe and persistent backache.
On vaginal examination the cervix feels thin,
tight and unyielding.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 71

Secondary Cervical Dystocia
This occurs due to previous trauma to the cervix, for
example, tears which were repaired, scarring or
from infection.
The cervix fails to dilate dispite of good uterine
contractions.
The management of cervical dystocia is by
encouraging the mother to lie on her back, elevation
of the bed foot to ease pressure on the cervix and
care must be taken to avoid lacerations.
Caesarean section should be done to hasten delivery
of the baby.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 72

Cervical Dystocia
Cervical dystocia can be further divided into one of three types,
any of which can occur as primary or secondary cervical
dystocia.
Rigid cervix
Annular detachment of the cervix
Oedematous anterior lip of cervix
Rigid cervix: is a rare condition in which the cervix fails to
dilate despite normal uterine contractions.
 It is characterised by severe persistent backache.
On vaginal examination the cervix feels thin, tight and
unyielding.
Annular detachment of the cervix: there is total circular
separation of the anterior or posterior lip of the internal OS
during or immediately after delivery.
Sometimes both lips are separated resulting in cervical
amputation
Rarely occurs
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 73

Trial of Labour
Trial of labour is a test of labour conducted
where there is a minor or moderate degree of
Cephalopelvic Disproportion (CPD) in which it is
difficult to decide whether delivery per vagina is
possible.
Common with borderline pelvis
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 74

Contraindications for trial of
labour
Grossly contracted pelvis
Medical or obstetrical complications
Mal-presentations, for example, breech
Elderly primigravida
Cases where trial of labour failed before
Cases of two previous caesarean sections
Remember: Your encouragement and friendly
attitude will boost the mother’s morale.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 75

Management of Trial of Labour
Explain the situation to the mother and
prepare her for possible operative
intervention.
Assess patient carefully on admission to
ascertain the following:
Whether the mother is in established labour
Presentation of foetus
Check for flexion of the head
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 76

Management of Trial of Labour
State of foetal heart, that is, rate, rhythm and volume
General condition of mother physically and
emotionally
Confine the mother to bed to prevent early rupture of
membranes
Close observations of temperature and blood
pressure every four hours
Observe foetal heart rate and maternal pulse
quarterly to half hourly
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 77

Management of Trial of Labour
Observe for signs of foetal and maternal distress.
Accurately observe and record for onset, strength,
frequency and duration of the contractions.
Closely observe the descent of the head every one to
two hours per abdominal palpation by the same
midwife if possible.
Encourage the mother to pass urine every two hours
and test for acetone to exclude acidosis.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 78

Management of Trial of Labour
Do vaginal examination every four hours to assess
the level of the presenting part, the degree moulding
and flexion, the dilation of the cervix (whether
progressive or not), the consistency of the cervix and
the presence or absence of caput.
Check whether the membranes are intact or
ruptured.
Encourage adequate hydration by giving intravenous
normal saline
Sedate the mother with pethidine in early labour to
promote rest, and reduce anxiety.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 79

Trial of Scar
Trial of scar is a test of labour for a woman with a
previous caesarean section scar, where no recurrent
indication is present.
Studies have shown that some 60 – 65% of previous
caesarean section mothers deliver per vagina,
involving same or fewer risks than a repeated
section.
The trial should be in a facility where, where a
caesarean section, this can be performed
immediately.
The midwife should be vigilant in making the
necessary observations.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 80

Management
Palpate abdomen gently
Check for any tenderness over the scar
Observe for any signs of impending rupture of the
uterus
Report any constant pain in abdomen

Caesarean Birth
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 81

Contraindications
CPD
Classical type of C/S
Malpresentation
Two previous scars, regardless of the causes
Previous scar wound did not heal with the first intension
Pregnancy occurs within 6months of a C/S
Over-distension due to multiple pregnancy or p0lyhydromnious

Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 82

Maternal
 Distress
Is a serious and life threatening condition, which
should not occur in this era.
Happens when the metabolism and the electrolyte
balance of the woman in labour is disturbed and this
can result into keto-acidosis hypotonic uterine
inertia.
Maternal and foetal distresses usually occur together
after prolonged labour.
 Often maternal and foetal distress present together
in women who have been in labour for a long time at
home and are brought to a health centre or hospital
in poor condition.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 83

Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 85

Management
The main investigation is testing for the
presence of acetone in the urine.
The management of Maternal Distress
involves giving an infusion of normal saline
to correct dehydration.
A caesarean section is performed when in the
first stage of labour.
In the second stage, an episiotomy is given
and delivery is assisted with vacuum
extraction.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 86

Foetal Distress
Foetal distress occurs when the foetus is deprived of
oxygen and, as a result, develops hypoxia.
The baby may be born as a still birth or develop
asphyxia and suffer brain damage.
Foetal tachycardia of more than 160 per minute is an
early sign while foetal bradycardia or pulse less than
110 beats per minute is a late sign of foetal distress.
Foetal heart acceleration related with uterine
contraction is a sign of foetal distress.
Sunday, March 2, 2025 ABNORMAL LABOR: BY PAUL NYONGESA 87

Causes of Fetal Distress

SHOULDER PRESENTATION

TRANSVERSE LIE
The long axis of the body of the
foetus is perpendicular to that of
the body of the mother

TRANSVERSE LIE
•Thus LADP (left acromio-dors0-posterior)
indicate that the baby’s lower shoulder is to
the mother’s left, and its back is towards her
back
•During labour, a presenting part which is so
high beyond the midwife’s finger should
arouse suspicion
•Later the shoulder is felt as a soft irregular
mass; ribs may be palpable in a small foetus.
