Tranexamic acid reduces blood loss after primary shoulder arthroplasty: a double-blind, placebo-controlled, prospective, randomized controlled trial.


ABSTRACT: Background:Tranexamic acid (TXA) is an antifibrinolytic that has been shown to decrease blood loss and transfusion rates after hip and knee arthroplasty, with only limited evidence to support its use in shoulder arthroplasty. This study was conducted to determine whether intravenous (IV) TXA is more effective than placebo in reducing blood loss after primary total shoulder arthroplasty (TSA). Methods:In this prospective, double-blind, placebo-controlled, randomized clinical trial, patients undergoing primary anatomic and reverse TSA were randomized to receive 1?g of intravenous TXA or a placebo of an equivalent volume of intravenous normal saline administered 10 minutes before the incision. The primary outcome measurement was calculated postoperative blood loss. Secondary outcomes included transfusion rates, weight of hemoglobin loss, hospital length of stay, and thromboembolic events. Results:The study enrolled 110 patients, 2 of whom were excluded because they did not have a postoperative hemoglobin measurement, and the remaining 108 patients (52 for TXA, 56 for placebo) were analyzed. There were no significant differences between TXA and placebo groups in preoperative characteristics. For the primary outcome, the TXA group had significantly lower postoperative blood loss of 1100.9?±?367.4?mL compared with 1274.5?±?460.0?mL for the placebo group (P?=?.03). For secondary outcomes, TXA had lower weight of hemoglobin loss compared with placebo (152.2?±?57.3?g vs. 178.0?±?65.8?g; P?=?.03). No patients in the TXA or placebo groups required a transfusion. Conclusions:Intravenous TXA reduced blood loss after primary TSA compared with placebo.
