OBSTETRICAL
EMERGENCIES
Care is a state
in which
something
does matter ; it
is the source of
human
tenderness
DEFINITION
• AN UNFORESEEN COMBINATION OF
CIRCUMSTANCES OR THE RESULTING
STATE THAT CALLS FOR IMMEDIATE
ACTION
• LIFE -OR -DEATH SITUATION
• INFREQUENT, UNANTICIPATED,
UNPREDICTABLE NIGHTMARE
Patient -1
• A 38 weeks G4P3 lady presents with
ROM and contractions. She is quite
distressed and thinks the baby is coming
out. You perform a pelvic examination
and next to the head you feel a pulsatile
cord…
Cord Prolapse
• Presentation: Cord in front of presenting part
before the rupture of membranes
• Prolapse: Cord in front of presenting part
after rupture of
membranes
Occult prolapse
Cord lying
alongside the
presenting part

•
Overall
- 50%
1st stage of labour - 70%

VASA PRAEVIA
• Fetal blood vessel lies in front of presenting
part
• Rupture
- exsanguination
of the fetus
Cause and Management
• Velamentous insertion
Fresh bleeding vaginally
with rupture of membranes
• Management: Signs of fetal
distress
Stat C.S
Send cord blood for Hb
estimation
PATIENT -2
Mother is pushing with each
contraction and the baby’s head starts
to come out. However, with each push,
the baby’s head comes out and then
retracts back in towards the
perineum. You quickly recognize this
as the “turtle sign”
Obstructed labour
• No advancement of presenting part
despite strong, uterine contractions
• Causes:
Cephalo-pelvic disproportion
Malpresentation shoulder/brow/persistent mento posterior
Deep transverse arrest
Pelvic mass
Fetal abnormalities - Hydrocephalus,
conjoined twins
Causes
Malpresentation:
Signs of obstructed labour
•
•
•
•
•
•
•
•
•
Presenting part fails to advance
Cervical dilatation slow
Formation of retraction ring
Early rupture of membranes
Formation of elongated sac of forewaters
If neglected, dehydration, ketosis
Caput succedaneum and moulding
urine output decreases
fetal distress

Management
Help – obstetrician, pediatrician
Episiotomy
Legs – elevate (McRoberts)
Pressure - suprapubic
Enter vagina – Rubin’s and Woods’
screw
Roll or Remove posterior arm
Zavanelli, Clavicular# ,
Symphysiotomy
McRoberts Maneuver
• hyperflexion of
maternal hips
• Increases intrauterine
pressure
(1,653mmHg - 3,262
mmHg)
• Increases amplitude of
contractions
(103mm Hg to 129mm
Hg)
All-Fours Maneuver(Gaskin Maneuver)
• Ina May Gaskin (1976)
• changes pelvic dimensions in a similar way to
McRoberts maneuver
• apply downward traction to disimpact the
posterior shoulder
Suprapubic Pressure
• direct posterior or oblique suprapubic
pressure
Rubin’s Maneuver
• adduction of the most accessible shoulder
• moves the fetus into an oblique position
and decreases the bisacromial diameter
Woods’ Cork Screw
Maneuver
• Abduct posterior shoulder exerting
pressure on anterior surface of posterior
shoulder
Deliver posterior arm
(Barnum Maneuver)
grasp the
posterior arm
and
sweep it across
the anterior
chest to deliver
Zavanelli Maneuver
• cephalic replacement via reversal of the
cardinal movements of labor
Clavicular Fracture
• fracture the anterior clavicle by pushing
it against the pubic ramus or using a
closed pair of scissors
• Symphysiotomy
Complications

•
Maternal morbidity
4th degree perineal lacerations
Cervical & Vaginal lacerations

Postpartum hemorrhage
Endometritis
Patient - 3
• Mother in third stage of labour. Using the
controlled cord traction, the midwife tries
to deliver the placenta. Unfortunately,
notices the descent of uterus instead of
placenta.
Uterine Inversion
• 1/20,000 deliveries
Causes:
• uterine atony (40%)
• Increase in intra
abdominal pressure
• Fundal attachment of
placenta (75%)
• Short cord
• Placenta accreta
• Excessive cord traction
Degrees of uterine inversion
• 1st - Dimpling of
fundus, remains
above internal os
• 2nd - fundus passes
through the cervix,
but lies inside
vagina
• 3rd - (complete)
Endometrium with
or without placenta
is outside the vulva
Dangers
• Shock - Neurogenic
Pressure on ovaries
Peritoneal irritation
• Hemorrhage
• Pulmonary embolism
• Infection
Management
• Uterine relaxant (terbutaline 0.25 mg IV
followed by 2 g of MgSO4 over 10 min)
• Treat hypovolumeia
• Without placenta: Repositioning
Uterine Inversion
Management(cont…)

•
•
With placenta: Do not remove placenta
Replace uterus
Bimanual compression
Hydrostatic pressure (O’Sullivan 1945)
Start oxytocin
Laparotomy
Patient - 4
A mother in second stage of labour
suddenly complains of persistent pain,
and bleeding per vagina becomes profuse
and the monitor shows decelerations in
fetal heart rate.
Uterine Rupture
• 1/2000 deliveries
Types:

bullets, knives
Congenital anomaly
Causes
Uterine injury during current pregnancy
• Before delivery
Intense spontaneous contractions
Labour stimulation
Intra-amnionic instillation
Perforation by internal catheter
External trauma - sharp or blunt
External version

Difficult forceps delivery
Breech extraction
Difficult manual removal of placenta
Fetal anomaly
• Acquired:
Placenta increta / percreta
Retroverted uterus (sacculation)
Diagnosis
• Prolonged fetal decelerations (70.3%)

Monitor tracing demonstrating fetal heart rate decelerations, increase in
uterine tone, and continuation of uterine contractions in a patient with
Management

placental separation and descent is
present. Manual removal fails.

•
•
•
•
•
Incidence: 1 in 2,562 deliveries

circulation and reaches pulmonary
capillaries
