Abstract

Introduction :

Blood loss during and after total knee arthroplasty (TKA) can lead to substantial morbidity and the need for blood transfusions. There are several methods to minimize blood loss and to decrease transfusion rates in patients undergoing TKA. Tranexamic acid is an antifibrinolytic agent with known efficacy for achieving these goals. Currently, many surgeons are performing TKA without the use of tourniquet. Consequently, the aim of the study is to evaluate whether tranexamic acid reduces blood loss during and after TKA without the adjunctive use of above-the-knee tourniquet.

Methods :

We performed a prospective randomized controlled trial (1:1 fashion) on the use of tranexamic acid versus placebo in 50 patients undergoing TKA (without tourniquet). The treatment group received two (preoperative and postoperative) 15 mg/kg doses. The primary endpoint was blood transfusion rate. We collected data about demographic and procedural characteristics, hemoglobin and hematocrit values, drain blood loss at 24 hours as well as adverse events.

Results :

There were no transfusions in the treatment group, whereas 32% of the control group required transfusion (p<0.01). The treatment group had higher hematocrit and hemoglobin levels at 24, 48 and 72 hours after surgery (all p<0.01) and lower drain loss at 24hours (363.4±141 vs 626±260ml, p=<0,001). There were no in-hospital or six-month thromboembolic complications.

Discussion :

A double-dose of tranexamic acid was safe and effective, reducing blood loss and preventing the need of blood transfusion in patients undergoing TKA without above-the-need tourniquet.

Keywords: Above-the-knee tourniquet, bleeding, blood transfusion, total knee arthroplasty, tranexamic acid. .

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."
