I now have comprehensive material to write thorough DNB exam notes. Here are the complete structured notes:

DNB Answer Notes: Postpartum Haemorrhage (PPH)

Based on: WHO Consolidated Guidelines for Prevention, Diagnosis and Treatment of PPH (2025)

DEFINITION & EPIDEMIOLOGY

PPH = blood loss ≥500 mL within 24 hours of vaginal birth; ≥1000 mL after caesarean section
Accounts for ~1/5 of all global maternal deaths
In most low-income countries, it is the leading cause of maternal mortality
Uterine atony = most common cause globally (4T's: Tone, Tissue, Trauma, Thrombin)
SDG Target 3.1: Reduce global MMR to <70/100,000 live births by 2030

SECTION 1: ANTENATAL INTERVENTIONS TO PREVENT PPH

1. Anaemia Diagnosis in Pregnancy

Full blood count (FBC) is the recommended method for diagnosing anaemia in pregnancy
Where FBC is unavailable: haemoglobinometer is preferred over haemoglobin colour scale
(Context-specific recommendation)

2. Iron and Folic Acid Supplementation

Daily oral iron + folic acid supplementation is recommended throughout pregnancy to reduce risk of anaemia and low birth weight (Recommended)

3. Intravenous Iron for Iron-Deficiency Anaemia

IV iron therapy is recommended in pregnancy when oral iron is ineffective or not tolerated (Context-specific)
Treat iron-deficiency anaemia before delivery to reduce PPH mortality risk

4. Antenatal Care & Risk Stratification

All pregnant women should have antenatal care for early identification of PPH risk factors
Risk factors: multiple pregnancy, previous PPH, grande multiparity, polyhydramnios, placenta praevia/accreta, bleeding disorders, anticoagulant use

SECTION 2: INTRAPARTUM INTERVENTIONS TO PREVENT PPH

5. Prophylactic Oxytocin (MOST IMPORTANT)

Recommendation 7 (Revalidated): Oxytocin (10 IU IM/IV) is the recommended uterotonic for prevention of PPH in all births (Recommended)

6. Alternative Uterotonics (Hierarchy)

Drug	When to Use	Dose/Route	Notes
Oxytocin	ALL settings (first choice)	10 IU IM or slow IV	Drug of choice
Carbetocin	Settings where refrigeration is unavailable	100 mcg IM	Heat-stable; as effective as oxytocin
Misoprostol	Community/primary care (no injectable available)	600 mcg sublingual	Usable by lay/community health workers
Ergometrine/Methylergometrine	When oxytocin unavailable	IM/IV	Avoid in hypertension; more side-effects
Oxytocin + Ergometrine	Second line	Combined	Avoid in hypertension

Key NEW recommendation: Carbetocin (heat-stable) is recommended when oxytocin is not available or cold chain cannot be assured.

7. Episiotomy

Routine/liberal use of episiotomy is NOT recommended for spontaneous vaginal birth (Not recommended)
If performed: medio-lateral incision preferred (midline = higher risk of anal sphincter injury)
Requires informed consent + effective local anaesthesia
No routine prophylactic antibiotics needed for episiotomy

SECTION 3: POSTPARTUM INTERVENTIONS TO PREVENT PPH

8. Active Management of Third Stage of Labour (AMTSL)

The primary component of AMTSL is administration of a uterotonic. Package includes:

Uterotonic drug (primary, essential)
Controlled cord traction (CCT) - small additional benefit when oxytocin is used
Late cord clamping (1-3 min delay recommended)
Uterine massage - NOT recommended routinely if uterotonic given

9. Cord Clamping

Recommendation (Revalidated): Delay cord clamping for at least 1 minute (and up to 3 minutes) after birth for improved maternal and neonatal outcomes

Recommended even in HIV-positive mothers (no evidence of increased HIV transmission risk)

10. Uterine Massage

Recommendation 20 (Revalidated): Sustained uterine massage is NOT recommended as routine PPH prevention in women who received prophylactic oxytocin

However, intermittent uterine tone assessment (periodic palpation) remains important for early PPH detection

11. Prophylactic Tranexamic Acid (TXA) - NEW

Prophylactic TXA is NOT recommended routinely for all women
Context-specific for high-risk women (e.g. placenta praevia, history of PPH, coagulopathy)

SECTION 4: DIAGNOSING PPH

12. Blood Loss Measurement - CRITICAL

Recommendation 21 (Updated): Use of a calibrated drape/collector for objective measurement of blood loss after vaginal birth is recommended over visual estimation

Visual estimation consistently underestimates blood loss by 30-50%
Calibrated drapes improve early PPH detection and trigger timely treatment

13. PPH Diagnosis Thresholds

Recommendation 22 (New): Initiate PPH treatment bundle when:

Measured blood loss ≥500 mL, OR
Measured blood loss ≥300 mL with early warning signs (tachycardia, hypotension, dizziness)

14. Uterine Tone Monitoring

Uterine tone assessment should occur regularly postpartum as part of monitoring
Boggy/soft uterus = suspect atony, act immediately

SECTION 5: FIRST-RESPONSE TREATMENT OF PPH

15. Treatment Bundle (PPH Care Bundle) - MOST IMPORTANT

Recommendation 29 (Revalidated): A standardized PPH Treatment Bundle for all women with PPH after vaginal birth:

"U-TITE" Mnemonic:

Uterine massage

Tranexamic acid (IV 1g)

IV fluids (isotonic crystalloids)

Toxic/uterotonics (additional oxytocin/ergometrine)

Examination of genital tract + Escalation of care

16. Oxytocin for Treatment

Recommendation 24 (Revalidated): IV oxytocin is the first-line drug for treatment of PPH due to uterine atony

Dose: 20-40 IU in 500-1000 mL normal saline IV infusion
If not available: ergometrine or misoprostol (600-800 mcg SL/sublingual)

17. Tranexamic Acid (TXA) - KEY

Recommendation 25 (Updated): TXA 1g IV is recommended as part of first-line treatment of PPH

Should be given within 3 hours of birth; ideally within 1 hour of PPH onset
Repeat dose of 1g IV if bleeding continues after 30 minutes
Mechanism: antifibrinolytic (inhibits plasminogen activation)
WHO WOMAN trial: TXA reduces death from haemorrhage by 19% when given within 3 hours

18. IV Fluids for Resuscitation

Recommendation 27 (Updated): Isotonic crystalloids (normal saline or Hartmann's) are recommended over colloids for fluid resuscitation in PPH

Crystalloids: widely available, inexpensive, no anaphylaxis risk
Goal: stabilize circulation while definitive treatment is underway
Caution: fluid overload in pre-eclampsia/cardiac disease

19. Uterine Massage for Treatment

Recommendation 26 (Revalidated): Uterine massage is recommended as part of the treatment bundle

Different from prophylactic sustained massage (which is not recommended)

SECTION 6: TREATMENT OF REFRACTORY PPH

20. Carboprost (PGF2α)

Recommended for atony not responding to first-line oxytocics
250 mcg IM/intramyometrial, can repeat every 15-90 min (max 8 doses)
Contraindicated in asthma

21. Bimanual Uterine Compression

Recommendation 33 (Context-specific): Bimanual uterine compression is recommended as a temporizing measure until appropriate care is available, for PPH due to uterine atony after vaginal birth

22. External Aortic Compression

Recommendation 34 (Context-specific): External aortic compression is recommended as a temporizing measure for PPH due to uterine atony

23. Non-Pneumatic Anti-Shock Garment (NASG)

Recommendation 35 (Context-specific): NASG is recommended as a temporizing measure for PPH (while awaiting definitive care)

24. Uterine Balloon Tamponade (UBT)

Recommendation 36 (Revalidated, Context-specific): UBT is recommended for PPH due to uterine atony after vaginal birth NOT responding to standard first-line treatment, provided:

Immediate surgical intervention + blood products are accessible
First-line protocol (uterotonics + TXA + IV fluids) is already implemented
Other causes (retained tissue, trauma) are reasonably excluded
Trained health personnel available
Maternal condition can be adequately monitored

25. Uterine Packing

Recommendation 37 (Updated): Uterine packing with plain gauze or haemostatic gauze is NOT recommended for PPH treatment

26. Uterine Artery Embolization (UAE)

Recommendation 38 (Context-specific): UAE is recommended if other measures fail and resources are available for PPH due to uterine atony

27. Surgical Interventions

Recommendation 39 (Revalidated): If bleeding does not stop despite uterotonics and conservative measures, surgical interventions are recommended:

Compression sutures (B-Lynch, modified Hayman)
Bilateral uterine artery ligation
Internal iliac artery ligation
Hysterectomy (peripartum) - definitive last resort

28. Cell Salvage

Recommendation 40 (New): Cell salvage is recommended only in context of rigorous research for PPH treatment

29. Blood Transfusion

Recommendation 41 (New): Decision to transfuse should be based on:

Underlying risk + continuous clinical + haematological assessment
Clear protocols for optimizing blood product use
Not on a single haemoglobin value alone

SECTION 7: RETAINED PLACENTA MANAGEMENT

30. Retained Placenta

Placenta not delivered within 15 min: initiate CCT, mobilize, empty bladder
Not delivered within 30 min: prepare for manual removal of placenta (MRP)

31. Antibiotic Prophylaxis for MRP

Recommendation 31 (Updated): Routine antibiotic prophylaxis is recommended for manual removal of placenta (Recommended)

Regimens: ampicillin, first-generation cephalosporins, or single dose IV amoxicillin 1g + clavulanic acid 200mg
Avoid ergometrine and PGE2 (dinoprostone/sulprostone) in retained placenta

32. IV Oxytocin for Retained Placenta

IV oxytocin for retained placenta in absence of PPH - very limited evidence; consensus-based use

SECTION 8: SUPPORTIVE CARE AFTER PPH

33. Iron Supplementation Post-PPH

Oral/IV iron to replenish iron stores after significant blood loss
Helps recovery from anaemia without mandatory transfusion

34. Monitoring

Close monitoring: pulse, BP, respiratory rate, urine output, uterine tone
Watch for: DIC, acute kidney injury, Sheehan syndrome (pituitary necrosis)

35. Psychological Support

Women who experience PPH have increased risk of PTSD and postnatal depression
Counselling and follow-up recommended

SECTION 9: HEALTH SYSTEM INTERVENTIONS

36. PPH Protocols and Drills

Every facility should have a written PPH protocol
Regular simulation drills improve team response time and outcomes

37. Task-Shifting

Misoprostol can be task-shifted to community/lay health workers
TXA self-injection being studied in community settings

38. Supply Chain

Ensure uninterrupted supply of uterotonics (oxytocin requires cold chain; carbetocin does not)
Calibrated drapes should be available at all birth facilities
