Tranexamic acid and hypotension-avoidance in major non cardiac surgery

Tranexamic acid and hypotension-avoidance in major non cardiac surgery

 

POISE-3: PeriOperative ISchemic Evaluation-3 Trial

The Perioperative Ischemic Evaluation-3 (POISE-3) trial will examine the safety and efficacy of tranexamic acid and the effect of a hypotension-avoidance strategy on ischaemic and bleeding endpoints in major noncardiac surgery in 10,000 participants.

The results of the tranexamic arm was presented at the ANZCA Annual Scientfic Meeting 2022 by Dr Tom Painter.

The trial received funding from the Australian National Health and Medical Research Council in 2019 (APP1162362) for $1.2 million dollars and completed recruitment of 9561 patients globally from 149 centres sites by mid 2021. The Australian and New Zealand sites which were supported by the NHMRC grant recruited 743 patients from 20 centres.

Principal investigators

Professor Kate Leslie AO and Dr Thomas Painter (Australian arm).
The trial has been developed and is being run internationally by the Population Health Research Institute in Canada and led by Dr PJ Devereaux.

Recruitment

From 2018 to 2021, the study recruited 9561 patients across 149 sites in 24 countries. The ANZCA CTN made an outstanding contribution to the trial with a total of 743 patients recruited across 20 centres between April 2019 and July 2021.

Participating countries

Australia, New Zealand, Canada and 19 others.

Trial summary

POISE-3 is a multicentre, international, randomised controlled trial of tranexamic acid (TXA) versus placebo and, using a partial factorial, of a perioperative hypotension avoidance versus hypertension-avoidance strategy in adults undergoing non cardiac surgery.

Sample Size
10000 patients

Study Duration
Five years

Primary outcomes
The co-primary efficacy outcome for the TXA trial is a composite of life-threatening bleeding, major bleeding, and critical organ bleeding at 30 days after randomisation. The co-primary safety outcome for the TXA trial is a composite of myocardial injury after noncardiac surgery (MINS), non-haemorrhagic stroke, peripheral arterial thrombosis, and symptomatic proximal venous thromboembolism at 30 days after randomisation. The primary outcome for the blood pressure management trial is a composite of vascular death, and non-fatal MINS, stroke, and cardiac arrest 30 days after randomisation.

Tranexamic acid arm results

The POISE-3 study randomised patients having noncardiac surgery to tranexamic acid (TXA) or placebo. The incidence of bleeding outcome was significantly lower with TXA (9.1%) than with placebo (11.7%) (hazard ratio, 0.76; 95% CI, 0.67 to 0.87). The incidence of the safety outcome (myocardial injury, stroke, arterial thrombosis, VTE) was 14.2% in the TXA group and 13.9% in the placebo group (hazard ratio, 1.02; 95% CI, 0.92 to 1.14) but non-inferiority was not established. As the absolute difference in the safety outcome was small, wider use of TXA in noncardiac surgery seems justified. As TXA is inexpensive these results will be rapidly translated into practice in Australia.
