Abstract
ABSTRACT The objective of this study was to conduct a systematic literature review to evaluate the impact of perioperative blood loss reduction and blood transfusion rate in patients undergoing adolescent idiopathic scoliosis correction surgery and to correlate these results with the different doses of tranexamic acid used in the literature. Ten databases (BVS, COCHRANE, EBSCOHOST, EMBASE, EPISTEMONIKOS, PROQUEST, PUBMED PMC, PUBMED, SCOPUS, WEB OF SCIENCE) were searched to find studies on the effectiveness of tranexamic acid in idiopathic scoliosis surgery. The mean differences in bleeding and transfusions were combined using a random-effects meta-analysis. A total of 17 studies with 1608 patients were included in the evaluation, demonstrating an Odds Ratio of 2.8 (95% CI: 0.8-4.3) as a measure of association for the risk of bleeding and transfusion in the control group (non-users of tranexamic acid), efficiency in reducing bleeding (p=0.03). Additionally, a mean reduction in bleeding of approximately 700 ml was observed. There was no statistical difference between the doses used. The systematic review showed that tranexamic acid effectively reduces bleeding and the need for transfusions, but there were no significant differences in the results between different doses of tranexamic acid. Level of Evidence II; Systematic Review.
