The document discusses the third stage of labor and management of postpartum hemorrhage. It describes the third stage as the period from delivery of the fetus to delivery of the placenta and membranes. Active management of the third stage with prophylactic uterotonics like oxytocin and controlled cord traction is recommended to reduce blood loss and duration. Postpartum hemorrhage is a major complication that can be life-threatening, so risk factors should be identified and prophylaxis with uterotonics given to all women during the third stage of labor.

1. Third stage of labor: events &
management

2. Labor
• Physiological process
• The products of conception passed form uterus to
outside world
• Normal labour: spontaneous in onset, at term, vertex
presentation, natural termination without any
complications affecting health of mother &/or
newborn
• Three stages of labor

3. Third stage: events
• After expulsion of fetus to expulsion of
placenta & membranes (afterbirths)
• Duration :15 min.(primigravida multigravida)
• AMTSL:5 minutes
• Placental separation
• Placental expulsion

4. Methods of placental separation
Central ( Schultze) separation
Marginal (Mathews Duncan) separation

6. Expulsion of placenta
• Contraction & retraction of Upper Uterine
Segment
• Placenta forced to lie in LUS/upper vagina
• Voluntary contraction of abdominal muscles
• Expulsion of placenta

7. Mechanisms to control bleeding
1. Effective retraction of
uterine muscles :
Living ligatures
2. Thrombosis of torn
sinuses
3. Myotamponade:
apposition of walls of
the uterus

8. Management of third stage
• Most crucial stage
• Strict vigilance
• Follow protocols
• Expectant management
• Active management

9. Expectant management
• Look for 3 classic signs of placental separation
– Lengthening of U. cord
– A gush of blood from vagina signifying separation
of placenta from uterine wall
– Change in shape of uterine fundus from discoid to
globular with elevation of fundal height
• Spontaneous/Controlled cord traction (CCT)
• Expulsion of placenta :20 minutes

10. Expectant management
• Massage the uterus
• Intramuscular Oxytocin : 10 IU
• Examination of placenta ,membranes, cord
• Inspect vulva, vagina & perineum

11. CCT
• 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

14. Examination of placenta ,membranes

15. Examination of membranes, cord

16. Active management
• AMTSL: Active Management of Third Stage of Labour
– Prophylactic uterotonic after delivery of baby
( Oxytocin 10 IU ,IM)
– cord clamping, cutting & Controlled cord traction
of U cord
– Uterine massage
• Excites powerful uterine contractions ,aid in early
placental separation, minimises blood loss &
duration of third stage (5 min.)

17. Third stage
• Most crucial
• Life threatening complications
• PPH(postpartum haemorrhage)
• Retained placenta
• Inversion of uterus
• Pulmonary embolism

18. Prophylaxis of PPH

19. PPH: hard facts
• Globally in 10-11% women having live births
• Duration between onset of massive bleeding
& death: 2 hours
• 14 million women worldwide
• 1.4 million women die annually
• India : 15-25% of maternal deaths due to PPH

21. PPH
• Primary PPH
– Haemorrhage <24 hrs of birth
• Secondary PPH
– Haemorrhage >24 hrs till 6 weeks of birth
• Primary PPH: 4T’s
– Tone
– Trauma
– Tissue
– Thrombosis

22. Primary PPH:causes

23. PPH : risk factors

24. Prophylaxis of PPH
• Improvement of health status of mother(Hb>11gm%)
• Identify high risk women
• Plan for institutional delivery /SBA
• Strict vigilance of all women in 3rd stage labor
• Practice AMTSL in all
• Examination of afterbirths ,should be a routine
• Explore Uterovaginal canal following difficult/
instrumental, destructive delivery

25. WHO GUIDELINES FOR
PROPHYLAXIS OF PPH

26. WHO guidelines

27. WHO guidelines

28. WHO guidelines

29. WHO guidelines
• Give uterotonics routinely during 3rd stage labor, in
all births
• Oxytocin 10 IU IM is drug of choice
• Use other uterotonics only when Oxytocin is not
available
• Late cord clamping( 1-3 min after birth) is
recommended
• Early cord clamping (<1min of birth): not
recommended until the neonate is asphyxiated &
needs immediate resuscitation
