PeriOperative ISchemic Evaluation-3 Trial
In Brief
A Phase 3 clinical trial evaluating Tranexamic Acid, Placebo (Saline), and 2 other interventions for Perioperative Bleeding and 2 related conditions. Completed, enrolled 9,535 participants across 114 sites in 23 countries.
Detailed Summary
This study is a multicentre, international, randomized controlled trial of tranexamic acid (TXA) versus placebo and, using a partial factorial design, of a perioperative hypotension-avoidance versus hypertension-avoidance strategy.

Timeline
Interventions
Within 20 minutes preceding the anticipated skin incision, patients will receive intravenous TXA at a loading dose of 1g over 10 minutes, with a second 1g bolus given at the end of surgery when closing the wound.
Within 20 minutes preceding the anticipated skin incision, patients will receive intravenous placebo (0.9% normal saline) at a loading dose of 1g over 10 minutes, with a second 1g bolus given at the end of surgery when closing the wound.
Perioperative hypotension-avoidance strategy includes: 1. Preoperative algorithm that only continues some antihypertensive medications in a stepwise manner for systolic BP ≥130 mm Hg before surgery, 2. Intraoperative blood pressure targeting a mean arterial pressure (MAP) ≥80 mm Hg 3. Postoperative algorithm that only continues some antihypertensive medications in a stepwise manner for systolic BP ≥130 mm Hg during the first 48 hours after surgery.
Perioperative hypertension-avoidance strategy (i.e., routine care) continues all antihypertensive drugs before and after surgery and an intraoperative BP strategy targeting a MAP ≥60 mm Hg.
