Post partum Haemorrhage

CME Hospital segamat by Dr Azreen

1. POSTPARTUM
HAEMORRHAGE
(PPH)

2. Definition
•Loss of blood more than 500 ml from the
genital tract post delivery of a baby (WHO)
•Excessive PVB that cause haematocrit drop
more than 10% that require immediate
transfusion (ACOG)

3. •PRIMARY PPH
–Loss of 500 ml or more of blood from the
genital tract within 24 hours of the birth of
a baby
Minor : 500-1000 ml with no clinical shock
Major : > 1000 ml
•SECONDARY PPH
–Abnormal or excessive bleeding from the
birth canal between 24 hours and 12 weeks
postnatally

5. •Visual blood loss estimation often
underestimates
•More accurate method
–Blood collection drapes
–Weighing swabs

6. Estimated Blood
Pad 120 cc
Tampon 50 cc
Gauze 30 cc

7. Haemorrhagic Shock
•Classification of haemorrhagic shock in
relation to clinical criteria and percentage of
total blood volume lost
•Total blood volume at term is approximately
100ml/kg
•Blood loss >40% of total blood volume
consider life-threatening

Profound 40 - 5050 Collapse, air hunger,
anuria

9. Causes of PPH
•4 T
–Tone (abnormality of uterine contraction –
UTERINE ATONY)
–Tissue (retained products of conception)
–Trauma (of genital tract)
–Thrombin (abnormality of coagulation)

10. TONE (UTERINE ATONY)
•75-90% of cases
•Uterine hyperdistension
–Macrosomic baby
–Multiple pregnancy
•Previous PPH
•High parity
•Precipitated or prolonged labour

11. •Chorioamnionitis
•Obesity (BMI > 35)
•Age > 40 years old
•Anemia

12. TISSUE
•Retained placenta

13. TRAUMA
•5-10% of cases
•Operative vaginal delivery
(vacuum / forcep)

14. •Caesarean section
•Mediolateral episiotomy
•Poor skill in guarding the perineum

15. THROMBIN
•Pyrexia in labour
•Placental abruption
•Pre-existing bleeding disorder like
haemophilia
•Patient on anti-coagulant

16. PREVENTION
•Identify the risk factors that may present
antenatally or intrapartum will help us to plan
the delivery
•However, most cases of PPH have no
identifiable risk factors
•Active management of 3
rd
stage of labour
lowers maternal blood loss and reduce risk of
PPH

17. •Active management of 3
rd
stage
–Use of uterotonic
–Uterine massage
–Control cord traction for delivery of placenta

18. •Prophylactic oxytocics should be given
routinely to all women
•As it reduce the risk of PPH by ≈60%
•Syntometrine (oxytocin + ergometrine)
may be used in absence of hypertension

19. •For cases with no risk factors and delivering
vaginally, give IM Oxytocin 5 iu or 10
iu
•For cases of Caesarean section, IV
Oxytocin 5 iu by slow infusion

20. •Syntometrine and Oxytocin have similar
efficacy in prevention of PPH
•However major difference in the side effect.
•Syntometrine : 5-fold increase of nausea,
vomiting, elevation of BP

21. •Carboprost (Haemabate®) is PGF2a
•Use as treatment rather than prevention

22. •Misoprostol (600 mcg orally) may be used in
home-birth setting but not as effective as
oxytocin
•All women with previous Caesarean section
must be check for placental site and any
presence of placenta accreta

23. •Patient with placenta accreta that
diagnosed antenatally should be managed
by consultant (O&G, Anaest) at tertiary
centre
•Reduce the blood loss by leaving the
placenta in the uterus after delivery of the
baby by fundal classical uterine incision .
Followed by hysterectomy / treatment with
methotrexate.

24. •Role of prophylactic interventional radiology
in case of antenatally diagnosed placenta
accreata
–Balloon occlusion
–Embolization of pelvic arteries
•Studies done show the procedure have value
in control of primary PPH and secondary PPH

26. 1. COMMUNICATION
•Alert all relevant professionals
•For major PPH, activate
RED ALERT
–Call experienced Midwife
–Call Specialist
–Alert Consultant

27. –Call Anaesthetist (specialist)
–Alert Consultant clinical Haemotologist on
call
–Alert blood bank
–Call PPK for delivery of specimens / blood
–Alert one member of team to record the
events, fluid, drugs and vital sign

28. •Communicate with patient and the partner
with clear information of what happening

29. 2.
RESUSCITATION
•A B C
•The measurement for resuscitation depend
on condition and degree of shock
•Assess Airway and Breathing
–Give oxygen 10-15 L/min via face mask
regardless the maternal [O
2]
–If airway is compromised due to impaired
conscious level, need to intubate with
anaesthetic assistance

30. •Evaluate Circulation
–2 large-bore branula (14-16 gauge)
(Take blood for FBC, coagulation profile,
BUSE/Cr/LFT, Fibrinogen, GXM 4 units)
–Position flat, lateral tilt
–Keep patient warm
–Give crystalloid infusion (Hartmann)
•In Major PPH, add
–Tranfuse blood asap

31. –Until blood is available, total volume of 3.5 litres
crystalloid infuse up to 2 L of warmed crystalloid
Hartmann solution and/or colloid (1-2 L) as rapidly
as required if blood still not available.
–May require DIVC regime
•FFP : 4 units for every 4 units of Pack Cells or PT/APTT >
1.5 x normal
•Platelet concentration : if Plt < 50 x 10
9
/L
•Cryoprecipitate : if fibrinogen < 1g/L

32. •Aim to restore the both blood volume and
oxygen-carrying capacity
•Volume replacement must be undertaken on
the basis that blood loss is often grossly
underestimated

33. •The therapeutic goals of management of
massive blood loss is to maintain
–Hb > 8 g/dL
–Plt count > 75 x 10
9
/L
–PT < 1.5 x mean control
–APTT < 1.5 x mean control
–Fibrinogen > 1.0 g/L
2006 Guideline of British Committee for Standards in Haematology

34. •Role of recombinant factor VIIa therapy
(rFVIIa)
–Used in treatment of haemophilia
–Used in reducing the bleeding in PPH
–In life-threatening PPH and in consultation with a
haematologist, rFVIIa is used as an adjuvant
therapy
–Dose 90 mcg/kg

35. •Role of anti fibrinolytic drugs – there is role of
management of obstetric hemorrhage.

36. 3. MONITORING &
INVESTIGATION
•Take blood as mentioned
•Monitor BP/PR every 15 minute is Minor PPH
•Continous BP/PR/RR in Major PPH (using
oximeter, cardiac monitoring, automated BP
recording)
•Put Foley catheter to monitor urine output

37. •In certain cases, consider arterial line
monitoring by experienced staff
•Transfer to ICU or HDW once bleeding is
controlled
•Documentation of fluid balance, blood, blood
products and procedure
•Central line by senior skilled-anaesthetist may
required

38. •Recommendation for central line and arterial
line for pressure monitoring when CVS is
compromised by haemorrhage or heart
disease

39. Anaesthetic management
•Anaeshetist needs to asses woman quickly , to initiate or
continue resuscitation to restore intravascular volume and
provide adequate anaesthesia.
•Presence of cardiovascular instability is a relative
contraindication to regional anaesthesia.
•Blockage of sympathetic system can potentially lead to
worsening hypotension due to hemorrhage.
•General anaesthesia is more appropriate when there is
continuing bleeding and the cardiovascular instability.
•Ventilator with high oxygen concentrations may be needed

40. 4. ARREST THE
BLEEDING
•Depends on the cause of the massive bleeding
•Common cause – Uterine Atony
–Mechanical
–Pharmacological
–Surgical

41. Mechanical
•Bimanual uterine compression to
stimulate uterus to contract
External
Internal

42. - Aortic Compression

43. Pharmacology
•Repeat IM Syntocinon or Syntometrine
•IV Pitocin 40 units in 500 ml Hartmann’s
solution, run at 125ml/hr
•IM Carboprost (Haemabate®) 0.25mg, may
repeated at interval not less than 15 min to a
maximum 8 doses (contraindicated in Asthma)

44. •Intramyometrial of Carboprost 0.25-0.5mg
•Misoprostol 1000 mcg rectally or cervagem
per rectally

47. Surgery
•If fail pharmacological
•Depends on the clinical circumstances and
available expertise
•First line is Balloon Tamponade
–Various types of hydrostatic balloon catheter
–Foley catheter, Bakri balloon, Sengstaken-
Blakemore oesophageal catheter and a
condom catheter

49. •The intervention describe as the
‘tamponade test’
•A ‘positive test’ : able to control PPH
following inflation of the balloon,
indicate that laparotomy is not required
•A ‘negative test’ : continued bleeding
following inflation of the balloon,
indication to proceed to laparotomy

50. •No evidence of how long the balloon
tamponade should be left in place
•Most cases, 4-6 hours of tamponade is
adequate to achieve haemostasis
•Should be remove during daytime hours
with presence of appropriate senior
staff as further intervention may be
necessary

51. •Haemostatic Brace Suturing
–B-Lynch suture (describe in 1997)

52. –Hayman suture, describe in 2002 with
modified compressive suture which does
not require hysterotomy
–Vertical compression sutures
•Effective technique to controlling severe
PPH and reducing the need for
hysterectomy
•Cx : pyometria, partial uterine necrosis

53. •Bilateral ligation of uterine arteries
•Bilateral ligation of internal iliac arteries
•Selective arterial embolization
•Hysterectomy
–Need second consultant to involved in
decision of hysterectomy

54. 4. ARREST THE BLEEDING
•Case of RETAINED PLACENTA
–empty bladder, attempt CCT
–If fail, proceed with Manual Removal of
Placenta (MRP) either under sedation or GA
–Take consent
–If under sedation, give IV Pethidine 25-50mg
stat, IV Midazolam 2.5-5.0 mg stat
–Continous SPO
2
monitoring, Litothomy position

55. - IV Ampicillin 1g stat, IV Flagyl 500 mg stat
- Fully gown, mask, long-sleeve glove
- Introduce one hand into vagina along the cord

56. - Other hand grasp the fundal of uterus and the hand just
now move through the cervix to the intrauterine cavity
- Detaching the placenta by sideways slicing movement
of the fingers

57. - Once able to detach the placenta part from the
intrauterine wall, grasp the placenta and bring out in
piece
- Then recheck again inside the uterus for any remnant
part of placenta

58. 4. ARREST THE BLEEDING
•Management of Genital Tract Trauma
–Suture the cervical / vaginal wall tear
–May need vaginal packing
–Cover with broad spectrum antibiotic

59. SECONDARY PPH
•Often associated with ENDOMETRITIS
•Risk factor for endometritis
–Prolonged labor
–PROM
–Anemia
–Underlying Diabetes
–Chorioamnionitis
–Operative deliveries: MRP, C-section, Instrumental
vaginal delivery

60. •Ix : FBC, CRP, high & low vaginal swabs, blood
culture if pyrexia
•Pelvic ultrasound, help in presence of POC
•Treatment :
–Antibiotic : Ampicillin and Metronidazole
–Uterotonics
–If continuing bleeding, may need balloon
tamponade or ERPOC
