REDUCTION OF POSTOPERATIVE BLOOD LOSS WITH COMBINED INTRAVENOUS AND TOPICAL ADMINISTRATION OF TRANEXAMIC ACID IN BILATERAL CEMENTLESS PRIMARY TOTAL HIP ARTHROPLASTY

The International Society for Technology in Arthroplasty (ISTA), 30th Annual Congress, Seoul, South Korea, September 2017. Part 2 of 2.



Abstract

Objectives

Tranexamic acid (TXA), an inhibitor of fibrinolysis blocking the lysine-binding site of plasminogen to fibrin, has been reported to reduce intraoperative and postoperative blood loss in patients undergoing primary total hip arthroplasty (PTHA) both with and without cement. Both intravenous (IV) and topical (TOP) administration of TXA can effectively reduce blood loss in THA without increasing risk of deep venous thrombosis (DVT). However, there have been few reports investigating the combination of intravenous and topical administration of TXA in bilateral cementless PTHA. We investigated the effects of combined intravenous and topical administration of TXA on postoperative blood loss, drainage volume, and perioperative complications in patients with bilateral simultaneous cementless PTHA for hip osteoarthritis.

Patients and methods

We retrospectively reviewed the demographic and clinical data of 41 patients who underwent bilateral simultaneous cementless PTHA for hip osteoarthritis from May 2015 to January 2017, of which there were 29 male (70.7%) and 12 female (29.3%) patients. Patients in IV group (n= 11) received only TXA (15 mg/kg) 10 min prior to the incision of each side; and patients in IV + TOP group (n=13) received i.v. TXA (15 mg/kg) combined with topical adiministration (1.0 g) of TXA during the each THA procedure; patients in control group (n=17) received the same dosage of normal saline both i.v. and topically. Outcome measures were total blood loss, hemoglobin, hematocrit value (HCT) changes preoperatively, and on the 1st, 3rd postoperative day, the amount of drainage, and perioperative complications.

Results

On the 1st, 3rd postoperative day, patients in group IV and group IV + TOP had significantly higher haematological parameters (haemoglobin, hematocrit value (HCT)) than patients in control group (P < 0.05 (group IV vs control group), P < 0.01 (group IV + TOP vs control group), respectively), while no significant differences found between patients in group IV and group IV + TOP (P > 0.05). The postoperative drainage volume of patients in group IV and group IV + TOP were significantly less than those in control group (P < 0.01, P < 0.01, respectively), while no significant differences found between those in group IV and group IV + TOP (P > 0.05). No significant differences were found in the perioperative complications (DVT or PE) among all three groups.

Conclusion

The combined administration of intravenous and topical TXA resulted in a significantly reduction in postoperative blood loss, compared with placebo group. No adverse perioperative complications were observed. This study supports the combined intravenous and topical administration of TXA in bilateral cementless PTHA.
