Postpartum Hemorrhage (PPH)

Definition

Postpartum Hemorrhage is defined as excessive bleeding following childbirth. Traditionally, it is classified as:

Primary (Early) PPH: Blood loss ≥500 mL after vaginal delivery or ≥1000 mL after cesarean section within the first 24 hours
Secondary (Late) PPH: Excessive bleeding occurring from 24 hours up to 6 weeks postpartum

Clinically, any amount of bleeding that leads to hemodynamic instability or requires intervention is considered significant, regardless of exact volume.

Epidemiology

Postpartum hemorrhage is one of the leading causes of maternal mortality worldwide, particularly in low-resource settings.

Accounts for approximately 25–30% of maternal deaths globally
Higher incidence in developing countries due to:
- Limited access to skilled birth attendants
- Delayed emergency care
- Poor antenatal monitoring

Physiology of Hemostasis After Delivery

After delivery of the placenta, several physiological mechanisms act to prevent bleeding:

Uterine contraction compresses blood vessels (living ligature mechanism)
Myometrial fibers constrict spiral arteries
Coagulation cascade activation promotes clot formation

Failure of these mechanisms leads to hemorrhage.

Classification

1. Primary (Early) PPH

Occurs within 24 hours of delivery
Most common and life-threatening form

2. Secondary (Late) PPH

Occurs from 24 hours to 6 weeks postpartum
Usually due to infection or retained products

Etiology (The 4 Ts)

The causes of postpartum hemorrhage are commonly remembered as the “4 Ts”:

1. Tone (Uterine Atony)

Most common cause (~70–80%)
Failure of uterus to contract effectively

2. Trauma

Genital tract lacerations
Uterine rupture
Cervical or vaginal tears

3. Tissue

Retained placental tissue
Placenta accreta spectrum

4. Thrombin

Coagulation disorders
Disseminated intravascular coagulation (DIC)

Side effects:
- Bronchospasm
- Diarrhea
- Hypertension

Tranexamic Acid

Tranexamic Acid plays a critical role in reducing mortality.

Dose: 1 g IV within 3 hours of delivery (may repeat)
Mechanism:
- Inhibits fibrinolysis → stabilizes clot
Key benefit:
- Reduces death due to bleeding

Stepwise Management Algorithm

Detailed Pathophysiology of Postpartum Hemorrhage

Postpartum hemorrhage is fundamentally a failure of physiological hemostasis at the placental site. Understanding this mechanism is crucial for targeted management.

Normal Hemostasis After Placental Separation

Myometrial contraction compresses spiral arteries
Retraction of uterine muscle fibers maintains vessel occlusion
Local clot formation stabilizes hemostasis

Failure of Hemostasis in PPH

1. Uterine Atony

Myometrium fails to contract
Spiral arteries remain open
Continuous uncontrolled bleeding

2. Retained Placental Tissue

Prevents effective uterine contraction
Persistent bleeding due to incomplete placental separation

3. Trauma

Direct vessel injury
Bleeding independent of uterine tone

4. Coagulation Failure

Inability to form stable clots
Leads to persistent oozing

Molecular Mechanisms

Oxytocin Receptor Dysfunction

Downregulation after prolonged labor
Reduced responsiveness to uterotonics

Inflammatory Mediators

Cytokines interfere with uterine contractility
Seen in infection-related PPH

Fibrinolysis Activation

Excess breakdown of fibrin clots
Controlled by drugs like Tranexamic Acid

Placental Pathologies and PPH

Placenta Previa

Placenta implanted in lower uterine segment
Poor contraction → increased bleeding

Placenta Accreta Spectrum

Types

Accreta: superficial attachment
Increta: invasion into myometrium
Percreta: penetration through uterus

Clinical Importance

Major cause of massive PPH
Often requires planned cesarean hysterectomy

Uterine Atony: In-Depth Analysis

Predisposing Factors

Overdistension (twins, polyhydramnios)
Prolonged labor
High parity
Infection

Cellular Mechanism

Impaired calcium influx in myometrial cells
Reduced actin-myosin interaction
Weak uterine contractions

Trauma-Related Hemorrhage

Types of Injuries

Vaginal lacerations
Perineal tears
Uterine rupture

Uterine Rupture

Coagulation Disorders in PPH

Primary Disorders

Pre-existing bleeding disorders

Secondary Disorders

Triggered by obstetric complications

Disseminated Intravascular Coagulation (DIC)

BP: 90/60 mmHg
Pulse: 120 bpm

Diagnosis

Primary PPH due to uterine atony

Reduces risk of uterine atony

2. Controlled Cord Traction (CCT)

Laboratory Evaluation and Interpretation in Postpartum Hemorrhage

Accurate laboratory assessment plays a critical role in guiding management of Postpartum Hemorrhage, especially in severe or ongoing bleeding.

Baseline Investigations

Immediately after diagnosis:

Complete Blood Count (CBC)
Blood grouping and crossmatching
Coagulation profile:
- PT (Prothrombin Time)
- aPTT (Activated Partial Thromboplastin Time)
Serum fibrinogen

Hemoglobin and Hematocrit

Initial values may appear normal despite significant blood loss
Serial monitoring is essential

Fibrinogen Levels

One of the earliest indicators of severe PPH
<2 g/L → high risk of massive hemorrhage

Platelet Count

<50,000 → increased bleeding risk
Indicates need for platelet transfusion

Coagulation Profile

Prolonged PT/aPTT suggests coagulopathy
Seen in severe hemorrhage or Disseminated Intravascular Coagulation

Point-of-Care Coagulation Testing

Thromboelastography (TEG) / ROTEM

Real-time assessment of clot formation
Helps tailor blood component therapy

Advantages

Faster than standard lab tests
Guides targeted transfusion
