Brief Summary
The study aligns with the strategic plan of New York-Presbyterian Hospital (NYPH) to reduce allogeneic blood product use and decrease unnecessary laboratory costs. One of the NYPH Quality and Patient Safety Goals for 2013 was to improve the appropriate use of transfusion guidelines and reduce unnecessary red blood cell (RBC) transfusions. Further, this study will help to answer whether RiaSTAP is a more effective product to treat bleeding than cryoprecipitate. In addition, this trial will provide investigators with preliminary data to apply for future federal funding opportunities, such as the National Heart Lung and Blood Institute sponsored R21 grant (PAR-13-025) that encourages research grant applications from investigators who propose to study research topics in blood banking and transfusion medicine aimed at improving the safety and availability of the blood supply and the practice of transfusion medicine. The investigators anticipate future follow-on studies further investigating fibrinogen concentrate and other similar therapeutics in other perioperative populations, such as in postpartum hemorrhage or surgical ICU settings. Finally, this study involves the use of a safer therapeutic, fibrinogen concentrate, to improve patient care and patient safety. This product does not require the time-intensive process of thawing; therefore, delays in patient care can be avoided by having the product readily available in the OR.

Outcome Measures
Primary Outcomes (1)
Intraoperative Blood Transfusion Total
The combined number of allogeneic blood products (platelets + Fresh Frozen Plasma (FFP) + RBCs) administered to subjects intraoperatively after study intervention.
Procedure length, the average for participants is approximately 6 hours
Secondary Outcomes (13)
24-hour Blood Transfusion Total
24 hours
Fibrinogen Repletion
Procedure length, the average for participants is approximately 6 hours
Incidence of Zero Transfusions
24 hours
Correction of Microvascular Bleeding
~30 min intraoperatively
CTICU Length of Stay
Length of Hospital Stay, the average for participants is approximately 7 days
- +8 more secondary outcomes
Study Arms (2)
RiaSTAP Arm
ACTIVE COMPARATORSubjects will be infused with RiaSTAP if the ROTEM FIBTEM A10 value is less than or equal to 10 mm and microvascular bleeding is present.
Cryopreciptiate Arm
ACTIVE COMPARATORSubjects will be infused with cryoprecipitate if the ROTEM FIBTEM A10 value is less than or equal to 10 mm and microvascular bleeding is present.
Interventions
ROTEM delta will be used to identify intraoperative coagulation abnormalities. A blood sample and reagents are placed into a small cup. A pin suspended from a wire is immersed into the sample. The pin rotates back and forth at a fixed angle. The movement of the pin is optically monitored and converted into a real time measurement that is represented graphically. Prior to clot formation, pin rotation is unhindered and is graphically represented as a straight line. As the subject's blood sample starts to clot, strands of clot form between the pin and the cup wall, restricting the movement of the pin depending on the strength of the clot. Graphically, this is represented as a symmetrical widening of the curve.
Subjects with hypofibrinogenemia who are randomized to the Cryoprecipitate arm will be transfused with Cryoprecipitate
Subjects with hypofibrinogenemia who are randomized to the RiaSTAP arm will be transfused with concentrated fibrinogen
