BackgroundPerioperative blood loss is a major concern in spinal fusion surgery and often requires blood transfusion. A large amount of perioperative blood loss might increase the risks of various perioperative complications. Recent clinical studies have focused on the perioperative administration of epsilon-aminocaproic acid (EACA) in spinal fusion surgery. The aim of this review was to evaluate the efficacy and safety of EACA in spinal fusion surgery.MethodsElectronic databases (MEDLINE, EMBASE, PubMed, and Cochrane Central Register of Controlled Trials) were systematically searched up to April 2021. Data on perioperative blood loss, blood transfusion, and complications were extracted and analyzed by RevMan software.ResultsSix randomized controlled studies comprising 398 patients undergoing spinal fusion surgery were included in this systematic review. Compared with the control group, the EACA group had significantly lower total perioperative blood loss, postoperative blood loss, postoperative hemoglobin, postoperative blood transfusion units, total blood transfusion units, and postoperative red blood cell transfusion units. Additionally, no significant differences were observed between the EACA and control groups in intraoperative blood loss, intraoperative blood transfusion units, intraoperative crystalloid administered, hospital stays, operative time, perioperative respiratory complications, and wound bleeding.ConclusionsEACA in patients undergoing spinal fusion surgery is effective in perioperative hemostasis without increasing the incidence of postoperative complications. However, more large-scale trials are needed to examine the long-term adverse side effects of EACA in spinal fusion surgery.Copyright © 2021 Elsevier Inc. All rights reserved.
