Tranexamic acid reduces surgical bleeding. Consistent with previous research, the POISE-3 (Peri-Operative Ischemic Evaluation-3) trial found that tranexamic acid reduces major bleeding by 25% and with a low probability of any increase in thromboembolic events. Wider tranexamic acid use will improve surgical safety, avoid unnecessary blood use, reduce the risk of transfusion transmitted infections, and save healthcare funds. 'Consideration of tranexamic acid use' should be included in the safe surgery checklist. We have the evidence, and we need to act on it.

Tobacco smoking is a leading preventable cause of death and increases perioperative risk. Determinants of smoking abstinence after noncardiac surgery and the association between smoking and 1-yr vascular outcomes are not fully elucidated. ⋯ Long-term tobacco abstinence is more likely after major surgery in those with serious medical comorbidities. Interventions to prevent smoking resumption after surgery remain a priority. Clinical trial registration NCT00512109.

Multicenter Study
Fluids, vasopressors, and acute kidney injury after major abdominal surgery between 2015 and 2019: a multicentre retrospective analysis.
Practice patterns related to intraoperative fluid administration and vasopressor use have potentially evolved over recent years. However, the extent of such changes and their association with perioperative outcomes, such as the development of acute kidney injury (AKI), have not been studied. ⋯ Despite decreased duration of hypotension during the study period, decreased fluid administration and increased vasopressor use were associated with increased incidence of AKI. Crystalloid administration below 10 ml kg-1 h-1 was associated with an increased risk of AKI. Although no causality can be concluded, these data suggest that prevention and treatment of hypotension during abdominal surgery with liberal use of vasopressors at the expense of fluid administration is associated with an increased risk of postoperative AKI.
