Randomized Controlled Trial of Tranexamic Acid in Total Knee Arthroplasty: Intravenous vs. Topical
연구 개요
상세 설명
This randomized controlled trial compares the blood loss of patients undergoing unilateral total knee replacements who randomly receive either the topical or the intravenous form of tranexmamic acid during surgery. Patients in the intravenous arm of the study will receive 1 gram of tranexamic acid in 10 milliliters of solution prior to inflation of the tourniquet and 1 gram of tranexamic acid in 10 milliliters of solution during closure. For patients in the topical arm of the study, prior to the release of the tourniquet they will receive 3 grams of tranexamic acid in 75ccs of solution directly on the site of the incision.
The primary result measurement will be blood drain output from the knee at 24 hours after surgery.

활성 비교기: Topical Tranexamic Acid
3 vials of tranexamic acid (1g tranexamic acid in 10cc each) must be mixed in the operating room by the team at the start of surgery with 45cc of saline solution (for a total of 3g tranexamic acid in 75mL solution).
This solution will be applied to the open joint surfaces with two 60mL syringes (one with 60mL and one with 15m).
The solution will be left in contact with the tissues for five minutes.
The surgeon will suction away excess solution.
The site may be irrigated before or after the tranexamic acid bath as long as the solution is in contact for at least five full minutes.
After that, the tourniquet will be released and the rest of the surgery will proceed according to the standard of care.

활성 비교기: Intravenous Tranexamic Acid
1 vial (1g of IV tranexamic acid in 10mL solution) will be administered prior to inflation of the tourniquet.
A second 1g dose of IV tranexamic acid will be given during initiation of the closure after the tourniquet is deflated and during closure.

Total Blood Loss
기간: during surgery
|
The amount of blood lost during surgery is the primary outcome measure.
Blood loss is determineusing an equation that calculates the patient's blood volume based on their height and weight, then multiplies the patient's blood volume by the change in their hematocrit after surgery compared to before surgery.
