Use of Tranexamic Acid in the Total Knee Arthroplasty.

Status Completed

Clinical Trial Summary

Tranexamic acid is a medication used to treat or prevent excessive blood loss during surgery. Previous studies have shown tranexamic acid (TXA) reduces blood loss and post-operative blood transfusion rate without significant complications. In addition, many meta-analyses have confirmed these results. This study also aims to determine how safe and effective tranexamic acid treatment is for different patients undergoing primary total knee arthroplasty.

Clinical Trial Description

Tranexamic acid (TXA) is used to control both intraoperative (IO) and postoperative (PO) bleeding during various surgical procedures. Moreover, TXA was found to indirectly reduce post-surgery infection rates and decrease hemorrhage-related mortality in trauma patients. This study aims to determine how safe and effective tranexamic acid treatment is for patients undergoing primary total knee arthroplasty. The study is a prospective, randomized, triple-blinded, placebo-controlled study. Ninety participants were enrolled between July 2021 and September 2022 and followed up with every patient for six months. The study was done in Damascus, Syria. Participants were randomly assigned following simple randomization procedures (computerized random numbers) to 1 of 2 groups. The allocation was put into concealed envelopes independent of the surgeon and the author, and the randomization was performed by a research fellow who was not involved in patient care. Participants who went unilateral primary TKA and did not use TXA, just IV normal saline (0.9% sodium chloride), formed the control group. In contrast, the intervention group comprised participants who went primary unilateral TKA and used two-dose intravenous tranexamic acid that was applied as follows: 10mg/kg of Tranexamic Acid in 100 Milliliters（ml) normal saline (0.9% sodium chloride), the first dose 15 minutes before the tourniquet deflation and the second dose at 180 minutes after the first dosage. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
