The objective of this study is to evaluate and compare the effects of intravenous and topical administration of tranexamic acid during revision hip arthroplasty on blood loss, allogenic blood transfusion rates, length of hospital stay and perioperative complications.
This study will use a prospective randomized single-blinded study design. The study will include one hundred and sixty patients undergoing revision total hip arthroplasty at a single institution (Mount Sinai Hospital (MSH), Toronto, ON, Canada). Tranexamic acid has been routinely administered as a single intravenous preoperative dose (unless contraindicated) in all revision hip arthroplasty cases at MSH since May 2012. In this study, participants will be randomized into 2 treatment groups: intravenous (IV) administration of tranexamic acid (TXA) and topical administration of TXA. The IV administration group will receive a single 20mg/kg dose of TXA prior to the skin incision. The topical administration group will have a 100mL solution (3g TXA in 100cc of normal saline) instilled into the surgical field during surgery. The primary outcome measured will be the delta hemoglobin (defined as the change in hemoglobin from preoperative measurement to POD 0, 1, 2, 3, 5). Secondary outcomes to be analyzed include intraoperative estimated blood loss, allogenic blood transfusion rates, length of hospital stay and postoperative complications.

Carbonic acid (H2C03). The hypothetical acid of carbon dioxide and water. It exists only in the form of its salts (carbonates), acid salts (hydrogen carbonates), amines (carbamic acid), and acid chlorides (carbonyl chloride). (From Grant & Hackh's Chemical Dictionary, 5th ed)

A dicarboxylic acid ketone that is an important metabolic intermediate of the CITRIC ACID CYCLE. It can be converted to ASPARTIC ACID by ASPARTATE TRANSAMINASE.
A strong dicarboxylic acid occurring in many plants and vegetables. It is produced in the body by metabolism of glyoxylic acid or ascorbic acid. It is not metabolized but excreted in the urine. It is used as an analytical reagent and general reducing agent.
