Summary

Human fibrinogen concentrate effectively treats dilutional coagulopathy in children undergoing craniosynostosis repair. This method improves fibrinogen polymerization and clot strength, avoiding fresh frozen plasma or platelet transfusions.

Clot Retraction and Fibrinolysis

After a fibrin clot is formed, the next step is clot retraction, a vital process facilitated by platelet contractile proteins, such as actin and myosin. These proteins pull the fibrin strands closer together and condense the clot. This action reduces the size of the clot, creating a smaller, denser structure that effectively seals off the damaged vessel. Clot retraction consolidates the clot and helps with wound healing by bringing the edges of the damaged blood vessel closer together.

Area of Science:

  • Anesthesiology
  • Pediatric Surgery
  • Hematology

Background:

  • Craniosynostosis repair can lead to significant blood loss and coagulopathy.
  • Standard treatments like cryoprecipitate are unavailable in Europe, and fresh frozen plasma (FFP) has limited efficacy for fibrinogen deficiency.

Purpose of the Study:

  • To evaluate the use of human fibrinogen concentrate (Hemocomplettan) in pediatric patients with impaired fibrinogen polymerization during craniosynostosis surgery.

Main Methods:

  • Retrospective analysis of nine pediatric patients undergoing major craniofacial surgery.
  • Data collected included coagulation tests, rotational thromboelastometry (ROTEM), transfusion needs, and postoperative outcomes.
  • Fibrinogen concentrate administration was guided by ROTEM findings.

Preparation of 3D Fibrin Scaffolds for Stem Cell Culture Applications

Published on: March 2, 2012

Main Results:

  • Impaired fibrinogen polymerization was the primary issue in dilutional coagulopathy.
  • Fibrinogen concentrate effectively achieved hemostasis without FFP or platelet transfusions in all cases.
  • Children showed rapid recovery, early extubation, and early ICU discharge.

Conclusions:

  • Fibrinogen concentrate is an effective treatment for improving fibrinogen polymerization and clot strength in pediatric craniosynostosis surgery.
  • This approach addresses key issues in dilutional coagulopathy, offering a viable alternative to FFP.
