 Physiological process
 Normal labour: spontaneous in onset, at term,
vertex presentation, natural termination without
any complications affecting health of mother &/or
newborn
 Three stages of labour
 First stage : onset of true labour pains to full dilatation
of cervix
 Second stage: full dilatation of cervix to expulsion of
fetus from birth canal
 Third stage: after expulsion of fetus to expulsion of
placenta & membranes (afterbirths)
PRANATI PATRA
 After expulsion of fetus to expulsion of placenta &
membranes (afterbirths)
 Duration :15 min.
 Placental separation
 Placental expulsion
 Separation of placenta is brought about by contraction
and retraction.
 Reduces the size of placental area.
 Placenta begins to tear off the uterine wall.
 At the area of separation a clot forms.
 Contraction & retraction of Upper Uterine Segment
 Placenta forced to lie in LUS/upper vagina
 Voluntary contraction of abdominal muscles
 Expulsion of placenta
1. Effective retraction of
uterine muscles :
Living ligatures
2. Thrombosis of torn
sinuses
3. Myotamponade:
apposition of walls of
the uterus
Mechanisms to control bleeding
 Constant watch.
 A hand is placed over the fundus
 Look for 3 classic signs of placental separation
3. Change in shape of uterine fundus from discoid to
globular with elevation of fundal height
 Modified Brandt Andrews method
 Left hand: palmar surface of fingers placed above pubic
symphysis. Body of uterus pushed upwards & backwards
 Right hand: cord traction in downward & backward
direction
 Uterus feels hard, contracted
 Massage the uterus
 Examination of placenta ,membranes, cord
 Inspect vulva, vagina & perineum
 Most crucial
 Life threatening complications
 PPH(postpartum haemorrhage)
 Retained placenta
 Inversion of uterus
 Pulmonary embolism
 Care for at least an hour after delivery.
 The mother should receive cleansing body
wash,mouth wash and perineal care. She
should be encouraged to empty bladder and
bedpan offered.
 Blood pressure , pulse,uterine contaction
,and bleeding should be checked every
15mts.
 The baby’s general wellbeing and security
of the cord clamp needs to be checked. as
the baby will chill after birth thoroughly dry
and wrap the baby.
 Mothers intended to breastfeed may be
encouraged. Early breastfeeding causes a
reflex release of oxytocin from the posterior
pituitary and stimulates the uterus to
contract.
 Labor is said to be normal if all are present except:
1. At term
2. Breech presentation
3. Spontaneous in onset
4. Healthy mother & neonate after delivery

The third stage of labour commences with the completed
delivery of the fetus and ends with the completed delivery
of the placenta and its attached membranes. The third
stage of labour begins once your baby is born, and ends
when you deliver the placenta and the empty bag of waters
attached to the placenta (membranes). It's normal for
there to be some bleeding during this stage of labour.

physiology and management of third stage of labour

  • 1.
  • 2.  Physiological process  Normal labour: spontaneous in onset, at term, vertex presentation, natural termination without any complications affecting health of mother &/or newborn  Three stages of labour
  • 3.  First stage : onset of true labour pains to full dilatation of cervix  Second stage: full dilatation of cervix to expulsion of fetus from birth canal  Third stage: after expulsion of fetus to expulsion of placenta & membranes (afterbirths)
  • 5.  After expulsion of fetus to expulsion of placenta & membranes (afterbirths)  Duration :15 min.  Placental separation  Placental expulsion
  • 6.  Separation of placenta is brought about by contraction and retraction.  Reduces the size of placental area.  Placenta begins to tear off the uterine wall.  At the area of separation a clot forms.
  • 7.
  • 8.
  • 9.
  • 10.  Contraction & retraction of Upper Uterine Segment  Placenta forced to lie in LUS/upper vagina  Voluntary contraction of abdominal muscles  Expulsion of placenta
  • 11. 1. Effective retraction of uterine muscles : Living ligatures 2. Thrombosis of torn sinuses 3. Myotamponade: apposition of walls of the uterus Mechanisms to control bleeding
  • 12.
  • 13.
  • 14.  Constant watch.  A hand is placed over the fundus  Look for 3 classic signs of placental separation
  • 15.
  • 16.
  • 17. 3. Change in shape of uterine fundus from discoid to globular with elevation of fundal height
  • 18.
  • 19.  Modified Brandt Andrews method  Left hand: palmar surface of fingers placed above pubic symphysis. Body of uterus pushed upwards & backwards  Right hand: cord traction in downward & backward direction  Uterus feels hard, contracted

  • 22.
  • 23.
  • 24.
  • 25.
  • 26.
  • 27.  Massage the uterus  Examination of placenta ,membranes, cord  Inspect vulva, vagina & perineum

  • 37.
  • 38.
  • 39.
  • 40.  Most crucial  Life threatening complications  PPH(postpartum haemorrhage)  Retained placenta  Inversion of uterus  Pulmonary embolism
  • 41.  Care for at least an hour after delivery.  The mother should receive cleansing body wash,mouth wash and perineal care. She should be encouraged to empty bladder and bedpan offered.  Blood pressure , pulse,uterine contaction ,and bleeding should be checked every 15mts.
  • 42.  The baby’s general wellbeing and security of the cord clamp needs to be checked. as the baby will chill after birth thoroughly dry and wrap the baby.  Mothers intended to breastfeed may be encouraged. Early breastfeeding causes a reflex release of oxytocin from the posterior pituitary and stimulates the uterus to contract.
  • 43.
  • 44.  Labor is said to be normal if all are present except: 1. At term 2. Breech presentation 3. Spontaneous in onset 4. Healthy mother & neonate after delivery
  • 45.  Labor is said to be normal if all are present except: 1. At term 2. Breech presentation 3. Spontaneous in onset 4. Healthy mother & neonate after delivery
  • 46.  Regarding the third stage of labor, following is not true: 1. Most crucial stage of labor 2. Duration is 15 minutes 3. Uterine inversion is most common complication 4. AMTSL is routine in all
  • 47.  Regarding the third stage of labor, following is not true: 1. Most crucial stage of labor 2. Duration is 15 minutes 3. Uterine inversion is most common complication 4. AMTSL is routine in all
  • 48.  The uterotonic of choice for prophylaxis of PPH in third stage of labor is 1. Syntometrine 2. Oxytocin 3. Misoprostol 4. carboprost
  • 49.  The uterotonic of choice for prophylaxis of PPH in third stage of labor is 1. Syntometrine 2. Oxytocin 3. Misoprostol 4. carboprost
  • 50.  All are true in relation to AMTSL except:  10 IU of Oxytocin , IM  Uterine massage  Reduces the duration of third stage  Perform in only high risk cases
  • 51.  All are true in relation to AMTSL except: 1. 10 IU of Oxytocin , IM 2. Uterine massage 3. Reduces the duration of third stage 4. Perform in only high risk cases
  • 52.  Complications during third stage of labor are all except 1. PPH 2. Chronic Uterine inversion 3. Retained placenta 4. Amniotic fluid embolism
  • 53.  Complications during third stage of labor are all except 1. PPH 2. Chronic Uterine inversion 3. Retained placenta 4. Amniotic fluid embolism
  • 54.  The most frequently observed method of placental separation : 1. Marginal separation 2. Central separation 3. None 4. both
  • 55.  The most frequently observed method of placental separation : 1. Marginal separation 2. Central separation 3. None 4. both
  • 56.  The most important method to control uterine bleeding following delivery 1. Myotamponade 2. Thrombosis 3. Contraction& retraction of uterine muscle 4. none
  • 57.  The most important method to control uterine bleeding following delivery 1. Myotamponade 2. Thrombosis 3. Contraction& retraction of uterine muscle 4. none
  • 58.  Following are true regarding misoprostol, except 1. Low cost 2. Easy storage 3. Administered rectally 4. Drug of choice for AMTSL
  • 59.  Following are true regarding misoprostol, except 1. Low cost 2. Easy storage 3. Administered rectally 4. Drug of choice for AMTSL
  • 60.  Following is true regarding Oxytocin 1. Given as IV bolus dose 2. Thermolabile 3. Contraindicated in cardiac patient 4. Causes hypertension
  • 61.  Following is true regarding Oxytocin 1. Given as IV bolus dose 2. Thermolabile 3. Contraindicated in cardiac patient 4. Causes hypertension
  • 62.  Prevention of PPH, all are true except 1. Treatment of anemia in antenatal period 2. Practice AMTSL in all 3. Home delivery in high risk cases 4. In forceps delivery, explore uterovaginal canal
  • 63.  Prevention of PPH, all are true except 1. Treatment of anaemia in antenatal period 2. Practice AMTSL in all 3. Home delivery in high risk cases 4. In forceps delivery, explore uterovaginal canal
  • 64.
  • 65. The third stage of labour commences with the completed delivery of the fetus and ends with the completed delivery of the placenta and its attached membranes. The third stage of labour begins once your baby is born, and ends when you deliver the placenta and the empty bag of waters attached to the placenta (membranes). It's normal for there to be some bleeding during this stage of labour.
