In acute major blood loss, dilution of clotting factors impairs coagulation. Fresh frozen plasma or coagulation factor concentrates are crucial, but further studies are needed for optimal management guidelines.

Area of Science:

  • Anesthesiology and Critical Care Medicine
  • Hematology

Context:

  • Acute major blood loss leads to dilutional coagulopathy.
  • Standard coagulation tests are often insufficient during massive transfusions.
  • Point-of-care systems like thrombelastography offer advantages.

Purpose:

  • To review the challenges in managing coagulopathy during massive blood loss.
  • To highlight the importance of fibrinogen and potential interference from colloids.
  • To discuss therapeutic options when fresh frozen plasma is unavailable.

Summary:

  • Massive transfusion dilutes plasma clotting factors, causing consumption and dilutional coagulopathy.
  • Fibrinogen levels critically decrease, impairing fibrin polymerization, exacerbated by colloids.
  • Fresh frozen plasma is the primary therapy; coagulation factor concentrates are alternatives when plasma is scarce.

Impact:

  • Highlights the limitations of current diagnostic and therapeutic approaches.
  • Underscores the need for evidence-based guidelines for coagulation management in massive transfusion.
  • Emphasizes the critical role of fibrinogen and potential colloid interactions in coagulopathy.
