Induction of labor or LSCS
15. • a pregnancy continuing beyond 2 weeks of the
expected date of delivery (> 294 days) is called
postmaturity or post-term pregnancy.
• Unknown causes
• Factors related;
– Wrong dates

24. Management…
• Prevention:
– Preconceptional counselling and care, screening and
early diagnosis
– Breaking bad news
• Expectant attitude: spontaneous expulsion within
2 weeks
• Methods of delivery
– Oral mifepristoe (200mg) and PV 25mcg misoprostol 4
hourly
– intravaginally 25-50mcg misoprostol 4 hourly
– 5-10 U of oxytocin in 500ml of RL
– Cesarean – previous 2 or more LSCS, placenta previa,
transverse lie
• Post-partum suppression of lactation
• Bereavement management - counselling
26. • The labor is said to be prolonged when the
combined duration of the first and second
stage is more than the arbitrary time limit of
18 hours.
• Due to
– Protracted cervical dilatation
– Inadequate descent
27. • Prolonged latent phase
– >20hrs in primi and >14hrs in multiparous women
– Causes
• Unripe cervix
• Malposition and malpresentation
• Cephalo-pelvic disproportion
• PROM
• Induction of labor
• Early onset of regional anesthetic
– Management:
Rest and analgesia
Augmentation (oxytocin or Prostaglandins)
Not an indication for cesarean delivery
28. Causes…
• First stage (failure to dilate cervix)
– Fault in power: abnormal contraction(inertia), in-
coordinated contraction
– Fault in passage: contracted pelvis, pelvic tumor or full
bladder
– Fault in passenger: malposition and malpresentation,
congenital anomalies(hydrocephalus)
– Injudicious use of sedatives and analgesics
• Second stage(non-descent)
– Fault in power: uterine inertia, exhaustion, analgesia,
constriction ring
– Fault in passage: CPD, spasm or old scaring, tumor
– Fault in passenger: malposition and malpresentation,
big baby, congenital malformation
29. Treatment…
• Prevention
– Antenatal detection
– Use of partograph
– Selective and judicious augmentation
– Change of posture, emotional support, avoid
dehydration
30. • Actual treatment
– First stage delay
• Verify fetal position and station
• Amniotomy and oxytocin infusion
• Pain relief
• LSCS if unsafe vaginal delivery
– Second stage delay
• Assisted delivery
– Forceps and vacuum delivery
• LSCS
32. • Obstructed labor is one where in spite of good uterine
contractions, the progressive descent of the presenting
part is arrested due to mechanical obstruction.
• Causes:
– Fault in passage
• Bony: CPD, contracted pelvis
• Soft tissue obstruction: cervical dystocia due to prolapse or
previous operative scarring, cervical or broad ligament fibroid,
impacted ovarian tumor or the non-gravid horn of a bicornuate
uterus below the presenting part.
– Fault in passenger
• Transverse lie, brow presentation, hydrocephalus, fetal ascites, big
baby, locked twins
33. • Effect on mother
– Immediate: exhaustion, dehydration, genital
sepsis, injury of genital tract, ruptured uterus,
– Remote: fistula, vaginal atresia
• Effect on fetus
– Asphyxia
– Intra-cranial haeorrhage
– Infection
– Fetal hypoxia and maternal acidosis
34. Treatment…
• Principles:
– Relieve obstruction
– Combat dehydration and ketoacidosis
– Control sepsis
• Obstetrics management
– Rule out rupture of uterus
• Vaginal delivery
• Cesarean section
36. • Shoulder dystocia occurs when either the
anterior or the posterior (rare) fetal shoulder
impacts on the maternal symphysis or on the
sacral promontory respectively
37. Risk factors:
(1) Previous shoulder dystocia,
(2) Macrosomia (>4.5 kg),
(3) Diabetes,
(4) Obesity (BMI >30 kg/m2),
(5) Induced labor,
(6) Prolonged first stage or second stage of labor,
(7) Secondary arrest of labor,
(8) Postmaturity,
(9) Multiparity,
(10) Anencephaly,
(11) Mid-pelvic instrumental delivery (more following ventouse
than forceps),
(12) Fetal ascites.
38. Complications:
• Fetal: asphyxia, brachial plexus injury,
humerus fracture, clavicle or sternomastoid
hematoma during delivery.
• Maternal: PPH (11%), cervical laceration,
vaginal tear, perineal tear (3rd and 4th
degree), rupture of uterus, bladder, sacroiliac
joint dislocation and morbidity
39. • Diagnosis: (1) Definite recoil of the head back
against the perineum, (2) Inadequate
spontaneous restitution, (3) Fetal face becomes
plethoric, (4) Failure of shoulder to descend.
• Management principles: Extra help is to be called
(a) To clear infant’s mouth and nose
(b) Not to give traction over baby’s head
(c) Never to apply fundal pressure as it causes
further impaction of the shoulder
(d) To perform wide mediolateral episiotomy as it
provides space posteriorly
(e) To involve the anesthetist (as analgesia is ideal)
and the pediatrician (for infant’s resuscitation).
40. Treatment…
• Suprapubic pressure
• McRoberts maneuvre: Abbduct matermal
thigh and hyperflex them onto abdomen.
Apply suprapubic pressure
• Woods maneuvre: posterior shoulder is
rotated to anterior position, Apply suprapubic
pressure
• All fours position
41. Hydrocephalus…
• Excessive accumulation of cerebrospinal fluid (0.5–1.5 L) in the
ventricles with consequent thinning of the brain tissue and
enlargement of the cranium.
• Usually associated with congenital anomalies.
• Diagnosis:
– Larger, globular and softer head
– Head high-up in pelvis and impossible to push down
– FHS is high up above the umbilicus
– USG:
• Globular cranial shadow
• Wide fontanels and sutures with Thinner vault bones
• Dilated ventricles with thinning of cerebral cortex
– Internal examination
• Gaping sutures and fontanels
• Cracking sensation on pressing the head
• In breech presentation, however, the diagnosis is not made until the
after coming head is arrested at the brim.
• Presence of open spina bifida points strongly toward hydrocephalus.
42. Management…
• Principle is to decompress the hydrocephalic
head in labor either in vertex or in breech
presentation.
• This is also done during cesarean delivery before
incising the uterus.
• Bladder is evacuated before hand.
• Once the labor is established and the cervix is 3–
4 cm dilated, decompression of the head is done
by a sharp pointed scissors or with a wide bore
(17 gauge) long needle.
44. • A labor is called precipitate when the combined duration of
the first and second stage is less than 3 hours.
• It is common in multiparae.
• Rapid expulsion is due to the combined effect of hyperactive
uterine contractions associated with diminished soft tissue
resistance.
• Maternal risks include:
Extensive laceration of the cervix, vagina and perineum
PPH due to uterine hypotonia that develops subsequent
to unusual vigorous contractions,
Inversion, Uterine rupture, Infection, Amniotic fluid
embolism.
• The fetal risks include—
intracranial stress and hemorrhage, bleeding from the
torn cord and direct hit on the skull, brachial plexus injury
are real hazards.
45. Treatment…
• The patient having previous history of precipitate labor
should be hospitalized prior to labor.
• During labor, the uterine contraction may be
suppressed by administering ether or magnesium
sulfate during contractions.
• Delivery of the head should be controlled.
• Episiotomy should be done liberally.
• Elective induction of labor by low rupture of
membranes and conduction of controlled delivery
is helpful.
• Oxytocin augmentation should be avoided.
47. • Disruption in the continuity of the all uterine
layers (endometrium, myometrium and
serosa) any time beyond 28 weeks of
pregnancy is called rupture of the uterus.
• Causes:
– Spontaneous
• Pregnancy: dilatation and curettage, grand multipare
congenital malformation of uterus, placenta percreta
• Labor: obstructed labor, grand multiparae
– Scar rupture
• Classical cesarean/hysterotomy scar
– Iatrogenic
• Oxytocins, prostaglandins, fall or blow to abdomen,
forceps, manual removal of placenta
48. • Scar dehiscence—
– disruption of part of scar and not the entire length.
– fetal membranes remain intact.
– bleeding is almost nil or minimal.
• Scar rupture—
– disruption of the entire length of the scar.
– complete separation of all the uterine layers including
serosa.
– rupture of the membranes with.
– varying amount of bleeding from the margins or from its
extension.
– uterine cavity and peritoneal cavity become continuous.
• Fetus and placenta: may or may not escape out of the
uterus
49. Diagnosis…
• Scar rupture:
– dull abdominal pain, slight PV bleeding, tender uterus, FHS
irregular or absent,
– sense of give away with acute abdominal pain and collapse
• Labor:
– Distended tender lower segment with fetal distress or
absent FHS
– Sense of give away, constant pain dull aching pain,
superficial fetal parts, absence of uterine contour, two
distinct swelling
– PV – recession of presenting part, bleeding
• Shock, internal hemorrhage,
50. Management…
• Preventive:
– At risk patient – mandatory hospital delivery
– Judicious use of oxytocin
– Careful monitoring
– Avoid undue prolongation, vaginal birth, forceps
delivery
• Treatment:
– Lapartomy: hysterectomy, repair or repair and
sterilisation
– Resuscitation
52. Malposition…
Occiput-Posterior Position
• Malposition refers to any position of the vertex
other than flexed occipito-anterior one.
• That is occiput lies over sacrum or sacro-iliac joint
• Causes:
– Shape of pelvis – anthropoid or android
– Anterior Low lying placenta
– Abnormal uterine contractions
– Abnormal fetal skull
53. Diagnosis…
• Abdomen: flat below umbilicus
• Palpation:
– Fetal limbs near midline and back in the flanks
– Head not engaged
• Auscultation: FHS heard on the flank or or the
midline
54. Management…
• 90% cases: internal rotation of head by 3/8th
of a circle remaining as usual.
• 10% cases: no rotation or minimal rotation
– Assisted vaginal delivery
– Liberal episiotomy
– Cesarean section
56. • Longitudinal lie with buttocks at the pelvic
brim
• Complete: flexed breech
• Incomplete: varying degrees of extension
– Frank breech: with extended legs
– Footling presentation
– Knee presentation
61. Management…
• Antenatal:
– Screening and identification
– External cephalic version
– Assisted vaginal breech delivery
– Elective cesarean delivery
• Criteria for vaginal breech delivery
– Avg fetal weight(1.5 – 3.5kgs)
– Flexed fetal head
– Adequate pelvis
– No any medical or obstetric complication
– Availabilty of OT and its components
• Indications of Cesarean Section (CS):
– Cases seen for the first time in labor with presence of
complications;
– Arrest in the progress of labor;
– Nonreassuring FHR pattern (Fetal distress);
– Cord presentation or prolapse.
62. Vaginal breech delivery…
• Spontaneous: very little assistance
• Assisted breech: assistance from beginning to
end
• Principle:
– Never to rush
– Never pull from below but push from above
– Always keep the fetus with the back anteriorly
63. • Positioning and toileting
• Episiotomy
• Patient is asked to bear down, NO TOUCH TO THE
FETUS policy is adopted till the buttocks are
delivered (with legs in flexed breech) up to the
trunk with the umbilicus.
• In frank breech: after buttocks are delivered – the
extended legs is delivered by pressure on
popliteal fossa in manner of abduction and
flexion of the thighs.
• Umbilical cord is pulled and mobilised to one side
• If back is posterior – rotated to make back
anterior
• Arms are delivered by hooking down each elbow
with finger.
• Delivery of the head is the most crucial step
64. • Delivery of the head should be within 5-
10mins of delivery of umbilicus.
• Techniques:
– Burns-Marshall method
– Forcep delivery
– Malar flexion and shoulder traction
• Resuscitation of the baby
• Other methods in arrest of descent:
– Pinard’s method
– Loveset maneuvre
66. • When the long axis of the fetus lies
perpendicularly to the maternal spine or
centralized uterine axis, it is called transverse lie.
• If obliquely placed – Oblique Lie
• Causes:
– Multiparity
– Prematurity
– Twins
– Hydraminos
– Contracted pelvis
– Placenta previa
– Pelvic tumors
– Congenital malformation of uterus
– IUD
67. Diagnosis…
• Inspection
– broader and often asymmetrical uterus
• Palpation
– Fundal height is less than period of amenorrhoea
– Fundal grip: empty
– Lateral grip: buttocks and head on either side of
midline with back felt anteriorly
– Pelvic grip: empty
• Auscultation: FHS heard usually higher area
• PV: prolapse of hand/leg or a loop of cord
68. Management…
• Antenatal: admitted at 37th wks – elective LSCS
• In ROM
• Early Labor:
– External cephalic version
– Cesarean section
• Late Labor:
– Baby alive – LSCS
– Baby dead – LSCS
• In macerated or premature baby (without ROM)
– Spontaneous rectification or version
– Spontaneous evolution
– Spontaneous expulsion
70. • Abnormal descent of the umbilical cord by the
side of the presenting part
• Types
– Occult prolapse – cord is placed by the side of
presenting part and not felt during PV
– Cord presentation – cord slips down below the
presenting part and lies in the bag of membrane
– Cord prolapse – cord lies inside the vagina or outside
the vulva following rupture of membrane
•
71. Causes
• Mal-presentation – transverse lie, breech with
flexed legs or footling and compound
presentation
• Contracted pelvis
• Prematurity
• Twins
• Hydraminos
• Placenta previa with marginal insertion of cord
• Iatrogenic – low ROM
72. Management…
• Cord presentation –
– DO NOT REPLACE CORD BACK
– If vaginal delivery contra-indicated – LSCS done
• Cord Prolapse
– Baby living
• Definitive t/t – LSCS
• If head engaged – forcep delivery
• If breech – breech extraction
• Bladder filling with 400-750ml NS done via catheter and
clamped – lifts the presenting part of the compressed cord
– Baby dead
• Labor allowed to proceed – spontaneous delivery
74. • The placenta is said to be retained when it is
not expelled out even 30 minutes after the
birth of the baby (WHO 15 minutes).
• 3 steps – Separation, descent and finally
expulsion
• Causes:
– Separated but retained – poor efforts to push
– Adherent placenta – atonic uterus, prolonged
labor, uterine malformation
– Morbid adherent placenta
– Placenta incarcerated due to constriction ring
75. • Dangers…
– Hemorrhage
– Shock
• Blood loss
• Retained for more than 1 hour
– Puerperal sepsis
– Recurrence in next pregnancy
76. Management…
• Period of watchful expectancy
• Empty bladder
• Controlled cord traction
• Manual removal of placenta
• Hysterectomy with or without partial
cystectomy
78. Perineum…
• While minor injury is quite common especially during
first birth, gross injury (third and fourth degree) is
invariably a result of mismanaged second stage of
labor.
• Causes:
– Over-stretching – Outlet contraction
– Rapid stretching – Shoulder dystocia
– Elderly primigravida – Forceps delivery
– Big baby – Scar in perineum
– Nulliparity – Precipitate labor
– Mid-line episiotomy
79. Classification…
• First degree: Injury to perineal skin only
• Second degree: Injury to perineum involving perineal
body (muscles) but not involving the anal sphincter
• Third degree: Injury to perineum, involving the anal
sphincter complex (both external and internal)
• Fourth degree: Injury to perineum involving the anal
sphincter complex (EAS and IAS) and anal epithelium
80.
81. Management…
• Recent tear repaired immediately following
delivery of placenta.
• Antibiotics given
• Positioning, toileting, local/general anesthesia
– Rectal and anal mucosa first sutured from above
downwards (interrupted sutures)
– Then Rectal muscles then torn ends of sphinchter
(figure of 8 stitch)
– Repair of perineal muscles
– Vaginal wall and perineal skin
82. After care…
• High fiber diet from 3rd diet from day 3
onwards
• Lactulose BD
• Antibiotics
• Physiotherapy and pelvic muscle exercise
• Sitz bath
84. • The disparity in the relation between the head
and the pelvis is called cephalopelvic
disproportion.
• Disproportion may be either due to an
average size baby with a small pelvis or due to
a big baby (hydrocephalus) with normal size
pelvis or due to a combination of both the
factors.
85. Diagnosis…
• Clinical:
– Previous history of spontaneous delivery of average size
baby rules out CPD
– But in primigravida, non-engagement of head suggest CPD
– Abdominal method: head is pushed down and seen
whether there is overlapping of symphysis pubis with
parietal bones.
– Abdomino-vaginal methods: bimanual examination, to see
if head can be pushed down towards ischial spine.
• Imaging:
– Lateral X-ray, USG measurement of bi-parietal diameter,
– MRI
86. Management…
• Inlet contraction:
– Spontaneous delivery
– Elective cesarean section
– Trial of labor
• Midpelvic and outlet disproportion:
– Elective cesarean section
– Assisted vaginal delivery
– Symphysiotomy
– Craniotomy if baby is dead
88. Perineum…
• While minor injury is quite common especially during
first birth, gross injury (third and fourth degree) is
invariably a result of mismanaged second stage of
labor.
• Causes:
– Over-stretching – Outlet contraction
– Rapid stretching – Shoulder dystocia
– Elderly primigravida – Forceps delivery
– Big baby – Scar in perineum
– Nulliparity – Precipitate labor
– Mid-line episiotomy
89. Classification…
• First degree: Injury to perineal skin only
• Second degree: Injury to perineum involving perineal
body (muscles) but not involving the anal sphincter
• Third degree: Injury to perineum, involving the anal
sphincter complex (both external and internal)
• Fourth degree: Injury to perineum involving the anal
sphincter complex (EAS and IAS) and anal epithelium

94. • The amount of blood loss in excess of 500 mL
following birth of the baby (WHO).
• “any amount of bleeding from or into the genital
tract following birth of the baby up to the end of
the puerperium, which adversely affects the
general condition of the patient evidenced by rise
in pulse rate and falling blood pressure is called
postpartum hemorrhage.
95. • Minor (<1L)

105. • A surgically planned incision on the perineum and
the posterior vaginal wall during the second stage
of labor is called episiotomy (perineotomy).
• It is in fact an inflicted second-degree perineal
injury. It is the most common obstetric operation
performed.
• Objective:
– Enlarge vaginal introitus
– Minimize tear or rupture of perineal muscle
106. Indication…
