TXA in Revision Total Shoulder Arthroplasty


This is a phase IV, randomized, single-blind, single-center study comparing calculated total blood loss, surgical drain output and hematoma formation in patients who receive 2 doses of Tranexamic Acid (TXA) versus control group undergoing revision total shoulder arthroplasty. Patients will be randomized to either receive 2 doses of IV TXA, first dose prior to surgical incision and second dose given 3 hours later or to the control group, where no TXA will be administered.

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Randomized
    • Intervention Model: Parallel Assignment
    • Primary Purpose: Treatment
    • Masking: Double (Participant, Care Provider)
  • Study Primary Completion Date: March 12, 2023

Detailed Description

The objectives of the study are to compare the effectiveness of IV TXA on reducing calculated total blood loss, surgical drain output and hematoma formation in patients undergoing revision total shoulder arthroplasty.


  • Drug: Tranexamic acid
    • IV, Total Dosage: 2 grams (1 gram before surgical incision + 1 gram, 3 hours after first dose)

Arms, Groups and Cohorts

  • Experimental: Tranexamic acid (TXA)
    • IV TXA
  • No Intervention: Control
    • No TXA

Clinical Trial Outcome Measures

Primary Measures

  • Total calculated total blood loss
    • Time Frame: up to 24 hours post-op
    • The volume of perioperative blood loss will be determined on the basis of the blood volume and change in hemoglobin from preoperatively to 1 day postoperatively. The volume of total perioperative blood loss will be determined according to the following formula: Total blood loss (ml) = 1000 x 〖Hb〗_loss/〖Hb〗_i
  • Total surgical drain output
    • Time Frame: up to 24 hours post-op
    • The floor nurse will also document the amount of blood in the indwelling hemovac surgical drain placed in the operative shoulder joint. The drain output will be documented every 8 hours. We will record the drain output for the first 16 hours after surgery – essentially 2 output shifts. If patients are in the hospital longer, we will record the third 24 hour drain output.

Secondary Measures

  • Number of participants with presence of hematoma
    • Time Frame: 2 weeks post-op
  • Number of participants who needed a post-op blood transfusion
    • Time Frame: 2 weeks post-op
  • Operative time
    • Time Frame: During operation, up to 4 hours
