Observational Study
Intraoperative hypotension is associated with myocardial damage in noncardiac surgery: An observational study.
Perioperative myocardial damage and infarction (MI) is associated with increased mortality and other postoperative complications. ⋯ In a cohort of 300 patients undergoing major elective noncardiac surgery, there was a high incidence of myocardial damage and an association between an intraoperative reduction in SBP more than 50% from baseline lasting more than 5 min and myocardial damage.

Review Meta Analysis
Targeting oliguria reversal in perioperative restrictive fluid management does not influence the occurrence of renal dysfunction: A systematic review and meta-analysis.
Interest in perioperative fluid restriction has increased, but it could lead to hypovolaemia. Urine output is viewed as a surrogate for renal perfusion and is frequently used to guide perioperative fluid therapy. However, the rationale behind targeting oliguria reversal - achieving and maintaining urine output above a previously defined threshold by additional fluid boluses - is often questioned. ⋯ Our data suggest that, even though event numbers are small, perioperative restrictive fluid management does not increase oliguria or postoperative ARF while decreasing intraoperative fluid intake, irrespective of targeting reversal of oliguria or not.

Randomized Controlled Trial
Black or white coffee before anaesthesia? Gastric volume measured by MRI: A randomised crossover trial.
In current preoperative fasting guidelines, coffee with milk is still regarded by many as solid food. Evidence on the consequences for gastric volume of adding milk to coffee 2 h before anaesthesia is still weak. ⋯ The study provides evidence that adding up to 50% full fat milk to coffee leads to no or only a minimal increase of the gastric volume 2 h later. The results support a liberalisation of policy on the addition of milk to hot drinks before planned anaesthesia.
