Brief Summary

One of the most common hemostatic derangements in pediatric open- heart surgery is an acute acquired hypofibrinogenemia. This compromises fibrin clot generation and platelet aggregation, resulting in increased bleeding and allogenic blood transfusions. Currently, fresh frozen plasma and cryoprecipitate are used to supplement fibrinogen in pediatric cardiac patients. We propose that replacing cryoprecipitate with fibrinogen concentrate will be as effective in treating post-CPB bleeding and will decrease total blood product exposure when used as part of a blood transfusion algorithm. We plan to include all patients undergoing cardiac surgery on CPB less than 12 months and a fibrinogen level \<250mg/dL while on bypass. We hope to demonstrate that fibrinogen concentrate is at least as effective as the standard of care in the management of peri- operative bleeding in neonatal patients undergoing cardiopulmonary bypass. If we are able to demonstrate that fibrinogen is at least as effective as the standard of care, then we would plan a multi-center trial to demonstrate the safety and efficacy of this medication. If we are able to demonstrate that fibrinogen concentrate is effective, fibrinogen concentrate could replace allogenic products and potentially decrease transfusion related morbidity in mortality in this population.

Outcome Measures

Primary Outcomes (1)

  • Total Units of Intraoperative Allogenic Donor Transfusions (ADT) Administered During Procedure Through ICU Arrival.

    For our study, 1 donor exposure = 1 unit of blood product transfusion. A blood product includes red blood cells, fresh frozen plasma, cryoprecipitate, and platelets.

    From administration of the drug during surgery to ICU arrival postoperatively (up to 24 hours)

Secondary Outcomes (5)

  • Chest Tube Output

    From administration end of surgery to 24 hours post operatively

  • Hours of Mechanical Ventilation

    From administration of the drug during surgery to extubation in the ICU (up to 30 days)

  • Length of Stay in Intensive Care Unit (ICU)

    From administration of the drug during surgery to discharge from the ICU (up to 3 months)

  • Length of Stay in Hospital

    From administration of the drug during surgery to discharge from the hospital (up to 6 months)

  • Count of Participants Who Died Within 30 Days Following Procedure

    From administration of the drug to 30 days following surgery
