We aimed to elucidate whether postinduction hypotension (PIH), defined as hypotension between anesthesia induction and skin incision, and intraoperative hypotension (IOH) are associated with postoperative mortality. ⋯ Despite limitations, including power and residual confounding, postoperative mortality was associated with IOH but not with PIH.

Observational Study
Effect of a national guideline on postoperative troponin surveillance: a retrospective cohort study.
We aimed to evaluate the effect of the 2017 Canadian Cardiovascular Society (CCS) guidelines on troponin surveillance after noncardiac surgery. ⋯ Although the odds of troponin ordering were slightly but significantly higher after publication of the CCS guidelines, the odds for detecting an MI and for mortality did not change.
