Investigation of Intravenous Tranexamic Acid With Anatomic and Reverse Total Shoulder Arthroplasty
Investigation of Intravenous Tranexamic Acid With Anatomic and Reverse Total Shoulder Arthroplasty
To compare intravenous Tranexamic Acid (TXA) versus normal saline placebo to determine
 whether or not TXA administration reduces blood loss, decrease in hemoglobin, and rate of
 transfusions following anatomic and reverse total shoulder arthroplasty (TSA) surgeries.
Anatomic and reverse total shoulder arthroplasty (TSA) is associated with the risk of
 moderate to significant blood loss that can lead to transfusions. Average estimated blood
 loss has been reported in the range of 354 to 361 mL intraoperatively, not accounting for
 additional postoperative blood loss postoperatively in surgical drains. Transfusion rates
 have been reported to range from 2.4% to 9.5% in recent studies, with rates over 30% for
 revision cases. Tranexamic acid (TXA) is a synthetic antifibrinolytic agent that is an
 established method of reducing blood loss and transfusion requirement for patients undergoing
 total hip and knee arthroplasty. TXA can be administered intravenously, topically
 (intraarticularly), or orally, with most available literature addressing intravenous and
 topical administration. Systematic reviews and meta-analyses of the total hip and knee
 arthroplasty literature demonstrate approximately a 30% decrease in blood loss and 50%
 decrease in transfusion rate with topical or intravenous administration of TXA compared to
 placebo. Moreover, the literature demonstrates no increased rate of thromboembolic or other
 complications associated with TXA administration for hip and knee arthroplasty.

 Despite proven efficacy in the hip and knee arthroplasty literature, there have been no
 studies analyzing the ability of TXA to reduce blood loss and transfusion rate following TSA.

 Purpose of the study is to compare intravenous Tranexamic Acid (TXA) versus normal saline
 placebo to determine whether or not TXA administration reduces blood loss, decrease in
 hemoglobin, and rate of transfusions following anatomic and reverse total shoulder
 arthroplasty (TSA) surgeries. With the hypothesis that intravenous TXA will reduce blood loss
 following TSA.
