Postpartum Hemorrhage (PPH): Causes, Symptoms, Treatment & Prevention

What Is Postpartum Hemorrhage (PPH)?

Postpartum hemorrhage (PPH) is excessive bleeding after childbirth — defined as blood loss of 500 ml or more following vaginal delivery, or 1,000 ml or more after a caesarean section. Postpartum hemorrhage is the single leading cause of maternal mortality worldwide, responsible for nearly 25% of all maternal deaths according to the World Health Organization (WHO).

In India, PPH continues to account for a significant share of maternal deaths, making awareness, early diagnosis, and timely treatment critical for every expectant mother, obstetrician, midwife, and healthcare facility.

Types of Postpartum Hemorrhage

There are two main types of PPH:

• Primary (early) postpartum hemorrhage — occurs within 24 hours of delivery. This is the most common and most dangerous form.

• Secondary (late) postpartum hemorrhage — occurs between 24 hours and 12 weeks after delivery, usually due to retained placental tissue or infection.

Causes of Postpartum Hemorrhage: The 4 Ts

Obstetricians use the "4 Ts" mnemonic to remember the four main causes of postpartum hemorrhage:

1. Tone — Uterine Atony (≈70% of PPH cases)

Uterine atony is the most common cause of postpartum hemorrhage. After delivery, the uterus must contract to compress the blood vessels that supplied the placenta. When it fails to contract, heavy bleeding follows. Risk factors include prolonged labour, multiple pregnancy, polyhydramnios, grand multiparity, and prolonged oxytocin use.

2. Trauma — Genital Tract Injury (≈20%)

Tears in the cervix, vagina, or perineum, episiotomies, uterine rupture, or surgical incisions during caesarean section can cause significant bleeding. Instrumental deliveries using forceps or vacuum increase this risk.

3. Tissue — Retained Placenta (≈10%)

Retained placental fragments prevent the uterus from contracting completely. Abnormal placental attachment — placenta accreta, increta, or percreta — is increasingly common in women with previous caesarean scars.

4. Thrombin — Coagulation Disorders (≈1%)

Bleeding disorders, severe pre-eclampsia, HELLP syndrome, amniotic fluid embolism, and disseminated intravascular coagulation (DIC) impair clotting and worsen PPH.

Symptoms and Warning Signs of Postpartum Hemorrhage

Recognising the early signs of postpartum hemorrhage can save a life. Watch for:

• Soaking through one or more sanitary pads per hour

• Passing large blood clots bigger than a plum

• A soft, "boggy" uterus on examination

• Rapid heartbeat or falling blood pressure

• Dizziness, fainting, or confusion

• Pale, cold, or clammy skin

• Persistent bright red vaginal bleeding beyond the first 24 hours

Any of these symptoms requires immediate emergency medical attention.

Risk Factors for Postpartum Hemorrhage

Women at higher risk of PPH include those with:

• A previous history of postpartum hemorrhage

• Multiple pregnancy (twins or triplets)

• Placenta praevia or placenta accreta

• Prolonged or induced labour

• Large baby (macrosomia)

• Pre-eclampsia or gestational hypertension

• Maternal anaemia

• Obesity (BMI > 35)

• Advanced maternal age

• Previous caesarean delivery

Identifying these risk factors before delivery allows clinicians to plan birth in appropriately equipped facilities.

Postpartum Hemorrhage Treatment and Management

Modern PPH management follows a stepwise, time-critical protocol — every minute counts.

Step 1: Immediate Response

• Call for emergency obstetric help

• Begin uterine massage

• Establish two large-bore IV lines

• Start IV fluids and oxygen

• Cross-match blood and prepare blood products

Step 2: Uterotonic Medications

First-line drugs for postpartum hemorrhage caused by uterine atony include:

• Oxytocin — first-line, WHO-recommended

• Carbetocin — long-acting alternative

• Methylergometrine (Methergine)

• Carboprost (PGF2α / Hemabate)

• Misoprostol — useful in low-resource settings

• Tranexamic acid (TXA) — proven by the WOMAN trial to reduce death from bleeding when given within 3 hours

Step 3: Mechanical and Surgical Interventions

When medications fail, treatment escalates to:

• Bimanual uterine compression

• Intrauterine balloon tamponade (e.g., Bakri balloon)

• B-Lynch compression sutures

• Uterine artery ligation or embolisation

• Emergency hysterectomy as a final, life-saving measure

Step 4: Safe Injection Practices in PPH Emergencies

During a postpartum hemorrhage emergency, multiple IV and IM medications must be administered rapidly. Auto-disable and safety-engineered syringes — such as Aurum's Au-Safe range — prevent needlestick injuries to busy clinical staff and eliminate the risk of reuse, a critical infection-control safeguard in any modern labour room.

How to Prevent Postpartum Hemorrhage

The most effective PPH prevention strategy is Active Management of the Third Stage of Labour (AMTSL), recommended by WHO and FIGO. AMTSL includes:

1. Prophylactic uterotonic (oxytocin) within one minute of birth

2. Controlled cord traction

3. Uterine massage after placental delivery

Additional preventive measures include:

• Treating antenatal anaemia

• Skilled birth attendance for every delivery

• Hospital delivery for high-risk pregnancies

• Functional emergency obstetric care (EmOC) at every level

• Stocking essential medicines, IV access devices, and safe injection equipment

Postpartum Hemorrhage Statistics (2026)

• PPH causes ~70,000 maternal deaths globally each year

• Accounts for nearly 25% of all maternal mortality worldwide

• Over 99% of PPH deaths occur in low- and middle-income countries

• India contributes a substantial share of global PPH deaths

• Most PPH deaths occur within the first 4 hours after delivery

Conclusion: Why Awareness of Postpartum Hemorrhage Matters

Postpartum hemorrhage is predictable, preventable, and treatable when recognised early. A chain of care — trained personnel, evidence-based protocols, essential medicines like oxytocin and tranexamic acid, and safe, reliable medical devices — protects every mother in the critical hours after childbirth.

Equipping labour rooms with quality safety syringes, IV cannulas, and infection-control products is a foundational step in any modern PPH preparedness plan.
