Management of Postpartum Hemorrhage
Immediate First-Line Management (Within Minutes)
Administer tranexamic acid 1 g IV over 10 minutes IMMEDIATELY alongside oxytocin 5-10 IU (IV or IM), initiate uterine massage and bimanual compression, and begin aggressive fluid resuscitation with physiologic electrolyte solutions. 1
Critical Time-Sensitive Actions
- Tranexamic acid MUST be given within 3 hours of birth—effectiveness decreases by approximately 10% for every 15 minutes of delay, and administration beyond 3 hours may be harmful. 1, 2
- TXA should be administered in ALL cases of PPH regardless of etiology (uterine atony, trauma, retained tissue). 1, 2
- A second dose of TXA 1 g IV can be given if bleeding continues after 30 minutes or restarts within 24 hours. 3, 1, 2
- TXA is contraindicated only in women with a known thromboembolic event during pregnancy. 3
Oxytocin Administration
- Administer oxytocin 5-10 IU slow IV or IM immediately postpartum. 3, 1
- For ongoing bleeding, add 10-40 units of oxytocin to 1,000 mL of non-hydrating diluent and run at a rate necessary to control uterine atony, not to exceed a cumulative dose of 40 IU. 4, 5
- The IV route is more effective than IM for PPH prevention. 2
Non-Pharmacological Interventions
- Perform uterine massage and bimanual compression immediately (one fist inside the vagina against the anterior lower uterine segment with counter-pressure on the abdomen). 3, 1
- Conduct manual uterine examination with antibiotic prophylaxis and careful visual assessment of the lower genital tract. 5
- Ensure bladder emptying to optimize uterine contraction. 5
Second-Line Pharmacological Management (If Bleeding Persists After 30 Minutes)
- Administer sulprostone within 30 minutes of PPH diagnosis if oxytocin fails to control bleeding. 5
- Sulprostone requires close clinical surveillance with continuous monitoring (ECG, non-invasive blood pressure, pulse oximetry). 6
Alternative Uterotonics
- Carboprost tromethamine (15-methyl PGF2α) is indicated for postpartum hemorrhage due to uterine atony which has not responded to conventional methods, including oxytocin and uterine massage. 7
- Methylergonovine 0.2 mg IM is CONTRAINDICATED in hypertensive patients (>10% risk of severe vasoconstriction and hypertension). 1, 2
- Methylergonovine should also be avoided in women with asthma due to bronchospasm risk. 1
Resuscitation and Transfusion Protocol
Fluid and Blood Product Management
- Initiate massive transfusion protocol if blood loss exceeds 1,500 mL. 3, 1
- Do NOT delay transfusion waiting for laboratory results in severe bleeding—administer RBC, fibrinogen, and FFP without awaiting laboratory confirmation. 3, 5
- Transfuse packed RBCs, fresh frozen plasma, and platelets in a fixed ratio. 3
- Target hemoglobin >8 g/dL and fibrinogen ≥2 g/L during active hemorrhage. 1, 5
Essential Supportive Measures
- Maintain normothermia: warm ALL infusion solutions and blood products; use active skin warming (clotting factors function poorly at lower temperatures). 3, 5
- Administer oxygen in severe PPH. 1, 5
- Re-dose prophylactic antibiotics if blood loss exceeds 1,500 mL. 3, 1
Mechanical Interventions (If Pharmacological Management Fails)
- Implement intrauterine balloon tamponade before proceeding to surgery or interventional radiology. 1, 2
- Pelvic pressure packing is effective for acute uncontrolled hemorrhage stabilization and may remain for 24 hours. 3, 1
- Non-pneumatic antishock garment can be used for temporary stabilization while arranging definitive care. 3, 2
Surgical and Interventional Radiology Options
When to Escalate
- If bleeding is not controlled by pharmacological treatments and intrauterine balloon within 30 minutes, proceed to invasive treatments. 6, 5
- Arterial embolization is particularly useful when no single bleeding source is identified, but requires hemodynamic stability for transfer. 1, 5
- Rule out hemoperitoneum before hospital-to-hospital transfer for embolization. 5
Surgical Interventions
- Uterine compression sutures (B-Lynch or similar brace sutures) can control bleeding. 1, 2
- Systematic pelvic devascularization, including uterine or internal iliac artery ligation, may be considered. 3, 2
- Hysterectomy should be considered as a last resort if bleeding continues despite all other measures. 2
Etiology-Specific Management
The Four T's Approach
- Tone (Uterine Atony): Most common cause (>75% of cases)—treated with uterotonic drugs and uterine massage. 8, 9
- Trauma (Lacerations, Rupture): Requires careful visual inspection and surgical repair; CT with IV contrast can localize bleeding in hemodynamically stable patients. 8, 3
- Tissue (Retained Placenta/Products): Manual removal or surgical evacuation; ultrasound shows echogenic endometrial mass with vascularity. 3, 9
- Thrombin (Coagulopathy): Correct with FFP, cryoprecipitate, and platelets; maintain fibrinogen ≥2 g/L. 1, 5
Imaging Considerations
- CT with IV contrast is useful in hemodynamically stable patients to localize bleeding sources, particularly for intra-abdominal hemorrhage. 8, 3
- Small (<4 cm) subfascial and bladder flap hematomas may not be clinically significant. 8, 3
- Ultrasound can diagnose retained products of conception. 3
- A >5 cm bladder flap hematoma should raise suspicion for uterine dehiscence. 8
Post-Acute Monitoring and Complications
- Continue hemodynamic monitoring for at least 24 hours post-delivery due to significant fluid shifts that may precipitate heart failure in women with structural heart disease. 1, 2
- Monitor for complications: renal failure, liver failure, infection, and Sheehan syndrome. 3, 1
- Consider thromboprophylaxis after bleeding is controlled, especially with additional VTE risk factors; early ambulation with elastic support stockings reduces thromboembolism risk. 1
Critical Pitfalls to Avoid
- Delaying TXA administration is the single most important error—every 15-minute delay reduces effectiveness by 10%. 1, 2
- Never delay treatment for active hemorrhage while waiting for laboratory results. 3, 5
- Failing to maintain normothermia and normal pH impairs clotting. 3, 5
- Do not administer methylergonovine to hypertensive patients. 1, 2
- Do not interpret hypodense edema at the cesarean incision site as dehiscence in the first postpartum week. 8
