• Target enrollment: 0
• Participant gender: All

Summary

Total hip arthroplasty (THA) is an excellent surgical procedure for patients with end-stage hip diseases. However, THA is associated with considerable blood loss and increasing needs for allogenic blood transfusion. Tranexamic acid (TXA) was reportedly effective reducing total blood loss (TBL) after standard THA. However, a TBL of one L is still high for elderly patients.

Floseal (Baxter, Deerfield, Illinois), a thrombin-based hemostatic agent, have been widely used in surgical procedure. However, there is no study investigating the effect of Floseal in THA procedures.This study anticipated that combination with the two different mechanism of topical hemostatic agent, Floseal, and intravenous TXA can bring a synergistic blood saving effect in THA patients.

Purpose:

Our purpose of this study therefore is to conduct a prospective randomized controlled trial to investigate the blood-conservation effect of combination of intravenous TXA and topical Floseal in a primary THA procedure.

Material and Methods:

The patients who are enrolled in this study will be assigned into three groups. The first group will be treated by combination of 1 g of TXA pre-operatively and two boluses TXA post-operatively intravenously and Floseal topical application, the second group by 1 g of TXA pre-operatively and two boluses TXA postoperatively intravenously without Floseal use, and the third group was control group which will be treated without TXA and Floseal. This study will observe whether there is difference in the blood-conservation effect by total blood loss calculation, hemoglobin loss and transfusion requirement between these three groups.

This study anticipate that combined use of intravenous TXA and Floseal in THA procedure is more effective in decreasing blood loss and blood transfusion than intravenous TXA application alone, and this formula do not increase the risk of thromboembolic disease.
