Coagulation management and transfusion in massive postpartum hemorrhage

Area of Science:

• Obstetrics and Gynecology
• Hematology
• Critical Care Medicine

Background:

• Postpartum hemorrhage (PPH) is a major cause of maternal mortality globally.
• Current guidelines for managing massive PPH and associated coagulopathy lack uniformity.
• Obstetric coagulopathy differs significantly from trauma-induced coagulopathy due to physiological changes during pregnancy.

Approach:

• Review of current literature and guidelines on PPH management.
• Analysis of the pathophysiology of obstetric coagulopathy.
• Evaluation of diagnostic tools and therapeutic interventions for massive PPH.

Key Points:

• Tranexamic acid should be administered early in massive PPH, irrespective of hyperfibrinolysis signs, due to limitations in current diagnostic tests.
• Transfusion strategies should be guided by laboratory and viscoelastic assay results, moving beyond empirical approaches.
• Point-of-care tests can effectively detect hypofibrinogenemia, enabling individualized fibrinogen replacement.

Conclusions:

• Factor deficiencies develop over time in PPH and require prompt management.
• Prothrombin complex concentrate or lyophilized plasma offer faster coagulation restoration than fresh frozen plasma (FFP) in cases of factor deficiency.
• Anticoagulation may be necessary once bleeding and hemostasis are controlled.
