Effectiveness of Different Fibrinogen Preparations in Restoring Clot Firmness

• Status: Not yet recruiting
• Trial end date: 2023-12-01
• Target enrollment: 0
• Participant gender: All

Summary

Fibrinogen concentrate is produced by different manufacturers using different purification technologies. The products available in Italy are three: RIASTAP (CSL Behring), FIBRYGA (Octapharma), and FIBRICLOTTE (LFB). RIASTAP and FIBRYGA are sold in 1-gram vials, and FIBRICLOTTE - in 1.5 grams vials. A recent in vitro study assessed how these products affected the clot firmness measured by the ROTEM FIBTEM maximum clot firmness (MCF) parameter. In vitro conditions, FIBRICLOTTE was verified to be the most efficient in increasing clot firmness.

The present study is aimed to assess, in a series of patients undergoing cardiac surgery with cardiopulmonary bypass, the hypothesis that the FIBRICLOTTE fibrinogen is superior to the RIASTAP fibrinogen in increasing the FIBTEM MCF parameter in a clinical model of bleeding (postoperative bleeding after complex cardiac surgery).
