Multicenter, Randomized Placebo-controlled Clinical Trial to Evaluate the Effect of Perioperative Use of Tranexamic Acid on Transfusion Requirements and Surgical Bleeding in Major Spine Surgery
Current evidence regarding the efficacy and safety of perioperative administration of tranexamic acid for antifibrinolysis does not suffice to support its use in major spinal surgery.
OBJECTIVES: To evaluate the effectiveness of tranexamic acid for decreasing transfusion requirements and bleeding in this patient population. To evaluate the safety of this antifibrinolytic agent in the intraoperative and mid-term postoperative period.
METHODS: Multicenter, randomized, double-blind, placebo-controlled clinical trial with parallel groups. The main outcome measure is intraoperative and postoperative transfusion requirements; blood loss and safety will also be evaluated. Previous results in other types of surgery suggest that tranexamic acid reduces transfusion requirements and blood loss. Hence, the hypothesis of this study is that tranexamic acid will significantly reduce blood loss in comparison to a placebo in major spine surgery.

Experimental: tranexamic acid
tranexamic acid will be administered as a bolus (10-mg/kg dose ) or as a fast, 20-minute intravenous infusion before performing the incision at the start of surgery, followed by perfusion of 2 mg/kg/hour up to the time the surgical wound is closed at completion of surgery

Comparador de Placebo: placebo
The placebo will be administered according to the same regimen and infusion time as the medication in the study arm (bolus or 20-minute fast infusion before the incision at the beginning of surgery followed by perfusion of 2 mg/kg/hour until closure of the surgical wound at completion of surgery)

O que o estudo está medindo?
Medidas de resultados primários
Medida de resultado |
Prazo |
|---|---|
|
The primary outcome measure is the number of transfused units required during the intraoperative and postoperative period
Prazo: 7 days postoperative period

7 days postoperative period

Medidas de resultados secundários
Medida de resultado |
Descrição da medida |
Prazo |
|---|---|---|
|
Total blood loss: intraoperative and postoperative values
Prazo: 48 hours postoperative
|
Intraoperative blood loss is evaluated by measuring the volume of suction aspirate and weighing the swabs with a precision digital scale.
Postoperative blood loss is determined by recording the volume of blood collected through the suction drains at 24 and 48 hours.
|
48 hours postoperative

|
Adverse events in the perioperative period, immediate postoperative period, and at mid-term
Prazo: up to 6 weeks after the procedure
|
Adverse events in the perioperative period, immediate postoperative period, and at mid-term (up to 6 weeks after the procedure) will be recorded, with special emphasis on follow-up of thrombotic events and clinically suspected deep venous thrombosis, renal function, and visual abnormalities reported by the patient
|
up to 6 weeks after the procedure
