The overall purpose of this study is to administer fibrinogen concentrate (RiaSTAP, CSL Behring, Marburg, Germany) with the goal of treating coagulopathic bleeding by improving hemostasis thereby reducing overall blood product transfusion after separation from cardiopulmonary bypass following aortic reconstructive surgery. With the current sample size this is a pilot study and in effect will determine the fibrinogen level response to fibrinogen concentrate administered during aortic reconstructive surgery. It will be underpowered to detect reduction in bleeding but comparison to historical controls will be included as a secondary outcome.

Further study details as provided by Duke University:

Primary Outcome Measures:
  • Fibrinogen Level Change [ Time Frame: Anesthesia Induction (Baseline), Pre RiaSTAP (est. 4 hr after baseline), Post RiaSTAP (est: 10 minutes after RiaSTAP administered), ICU Admission (est. 6 hours after baseline), 24 Hour post op (est: 24-30 hr after baseline) ] [ Designated as safety issue: No ]
    Fibrinogen levels will be assessed only at the timepoints listed in the timeframe and for a maximum of 24 hours.

Secondary Outcome Measures:
  • Total Blood Product Units Administered. [ Time Frame: Operating room admission thru 48 hour . ] [ Designated as safety issue: No ]
    As a secondary outcome we will record the total number of blood products administered over a 48 hour period.
