Viscoelastic Hemostatic Assays for Postpartum Hemorrhage

Area of Science:

• Obstetrics and Gynecology
• Hematology
• Critical Care Medicine

Background:

• Postpartum hemorrhage (PPH) poses significant risks, necessitating effective methods for assessing hemostatic competence.
• Traditional methods for evaluating coagulation have limitations in providing real-time, comprehensive data.
• Viscoelastic hemostatic assays (VHAs) offer a dynamic assessment of clot formation and function.

Purpose of the Study:

• To highlight the importance and effectiveness of VHAs in managing PPH.
• To discuss the advantages of VHAs over conventional coagulation tests.
• To identify barriers to VHA adoption and propose solutions.

Main Methods:

• Review of current literature on VHAs in the context of PPH.
• Comparison of VHAs (thromboelastography, rotational thromboelastometry) with clinical observation and standard coagulation tests.
• Discussion of VHA applications in various obstetric and gynecologic conditions.

Main Results:

• VHAs provide a comprehensive, point-of-care assessment of hemostasis, evaluating the entire clotting process.
• Advantages include rapid results, serial monitoring capability, and assessment of all blood components' contributions.
• VHAs are applicable beyond PPH to conditions like uterine atony, preeclampsia, and coagulopathies.

Conclusions:

• VHAs are crucial for guiding blood component therapy and hemostatic management in PPH.
• Underutilization is linked to interpretation difficulties, lack of standardization, and insufficient large-scale clinical trials.
• There is a critical need for increased VHA utilization and research to improve obstetric patient outcomes.
