Immediate Management of Postpartum Hemorrhage
Administer tranexamic acid 1 g IV over 10 minutes immediately upon diagnosis of PPH (blood loss >500 mL vaginal or >1000 mL cesarean), alongside uterotonics, with a second 1 g dose if bleeding continues after 30 minutes—this must be given within 3 hours of birth as benefit decreases 10% every 15 minutes and becomes potentially harmful after 3 hours. 1
Initial Simultaneous Actions
When PPH is diagnosed, implement these interventions concurrently:
Pharmacologic Management (First-Line)
- Oxytocin: 5-10 IU slow IV or IM push, followed by maintenance infusion up to cumulative 40 IU 2
- Tranexamic acid: 1 g IV over 10 minutes within 3 hours of birth, regardless of suspected cause (uterine atony, trauma, or other) 1
- Give a second 1 g dose if bleeding persists after 30 minutes or restarts within 24 hours
- Critical timing caveat: Do NOT give beyond 3 hours postpartum—it becomes potentially harmful 1
Immediate Physical Interventions
- Manual uterine examination with antibiotic prophylaxis 2
- Uterine massage and bimanual compression 1
- Visual inspection of lower genital tract for trauma 2
- Bladder emptying 2
Resuscitation
- Fluid replacement and hemodynamic monitoring 1
- Oxygen administration 2
- Warming measures: heat infusion solutions, blood products, and active skin warming to prevent hypothermia 2
Escalation Algorithm (If Bleeding Continues)
Second-Line (Within 30 Minutes)
- Sulprostone if oxytocin fails 2
- Maintain fibrinogen ≥2 g/L during active hemorrhage 2
- Transfuse RBC to maintain hemoglobin >8 g/dL 2
Third-Line (Before Surgery)
Fourth-Line (Invasive Interventions)
Progress from less to more invasive:
- Non-surgical: External aortic compression, non-pneumatic antishock garment 1
- Surgical: Uterine compression sutures (B-Lynch), arterial ligation, or hysterectomy 1, 2
- Interventional radiology: Arterial embolization (only for hemodynamically stable patients with slow persistent bleeding) 2
Critical Practice Points
The 2018 WHO guideline represents a major shift: Tranexamic acid is now recommended for ALL cases of PPH at diagnosis, not just refractory cases as in the 2012 recommendation. 1 This change is based on mortality reduction data showing that early administration saves lives.
Common pitfall to avoid: Delaying tranexamic acid administration while waiting for uterotonics to work. The evidence shows benefit decreases by 10% for every 15-minute delay, with no benefit after 3 hours and potential harm thereafter. 1 Give it early alongside—not after—uterotonics.
Contraindication: Avoid tranexamic acid only in women with known thromboembolic events during pregnancy. 1
Blood product administration: Do not wait for laboratory results during active hemorrhage—transfuse RBC, fibrinogen, and FFP based on clinical assessment. 2
Cesarean-specific consideration: Suspect intra-abdominal or retroperitoneal bleeding even without vaginal bleeding or ultrasound findings in delayed PPH after cesarean—relaparotomy should not be delayed. 3
