Brief summary

The purpose of this study is to determine the relative effectiveness of two drug agents, Tranexamic acid (TXA) and aminocaproic acid (Amicar), that act through a similar mechanism of action. These agents are used to decrease blood loss that is a result of major surgery, like total joint arthroplasty. A secondary goal will be investigate the cost-analysis of total hospitalization. Both TXA and Amicar are both currently used in the care of patients undergoing total joint arthroplasty. Subjects will be randomly assigned to the TXA or Amicar arm. All data needed for this study including blood loss, need for transfusion, preoperative and lowest postoperative hematocrit and hemoglobin, and complications will be collected during the hospitalization stay. Our Hypothesis is that TXA and Amicar will have similar effectiveness in preventing intraoperative blood loss and the need for transfusion post-op than Amicar. A detailed cost analysis will show that the overall cost of performing the operative procedure, including transfusions, OR time, and total costs associated with admission cost will be more decreased with Amicar as compared to TXA.

Participants by arm

ArmCount
Tranexamic Acid (TXA) - Total Hip Arthroplasty
TXA will be administered as a 1 gm dose IV prior to the procedure then as a repeat dose of 1 gram at the time of wound closure. These doses are currently used at Duke for TKAs and THAs per standard of care by the orthopaedic team. All data needed for this study including blood loss, need for transfusion, preoperative and lowest postoperative hematocrit and hemoglobin, and complications will be collected during the hospitalization. TXA: Subjects randomized to receive TXA will receive this during surgical intervention
46
Epsilon-aminocaproic Acid (Amicar) - Total Hip Arthroplasty
Administered 5g in 250mL of IV normal saline over 15 minutes prior to the procedure and then an infusion of 5g at the time of wound closure. These doses are currently used at Duke for TKAs and THAs per standard of care by the orthopaedic team. All data needed for this study including blood loss, need for transfusion, preoperative and lowest postoperative hematocrit and hemoglobin, and complications will be collected during the hospitalization. Amicar: Subjects randomized to receive Amicar will receive this during surgical intervention
