Randomized Controlled Trial
Relative contributions of anaemia and hypotension to myocardial infarction and renal injury: Post hoc analysis of the POISE-2 trial.
Hypotension and postoperative anaemia are associated with myocardial and renal injury after noncardiac surgery, but the interaction between them remains unknown. ⋯ Postoperative anaemia and hypotension were meaningfully associated with both our primary composite and AKI. However, lack of significant interaction suggests that the effects of hypotension and anaemia are additive rather than multiplicative.

Postoperative delirium (POD) has a negative impact on prognosis, length of stay and the burden of care. Although its prediction and identification may improve postoperative care, this need is largely unmet in the Brazilian public health system. ⋯ A predictive model composed of three indicative readily available features performed better than those with numerous perioperative features, pointing to its feasibility as a prognostic tool for POD. Further research is required to test the generalisability of this model.

Case Reports
Long Duration of Action of Tranexamic Acid After Cardiac Surgery in a Hemodialysis Patient: A Case Report.
A 61-year-old woman with chronic renal dysfunction was scheduled to undergo aortic valve replacement. After a bolus of 1 g tranexamic acid (TXA), the TPA (tissue-plasminogen activator)-test result with the ClotPro system demonstrated extensive inhibition of fibrinolysis. ⋯ Although TXA levels dropped to 6.9 μg/dL after hemodialysis on postoperative day (PoD) 1, fibrinolytic shutdown on the TPA-test remained unchanged until PoD 2. In dialysis patients, low-dose TXA <1 g may be considered for reducing seizure and thromboembolic complications after cardiac surgery.
