Incidence and risk factors for perioperative hypotension during noncardiac surgery: A retrospective cohort study
Abstract
Perioperative hypotension (POH) is frequent in noncardiac surgery and is linked to acute kidney injury (AKI), myocardial injury after noncardiac surgery (MINS), and increased postoperative resource use. Previous studies have applied inconsistent POH definitions and risk models. This study aimed to determine the incidence of POH and identify independent risk factors, while assessing the robustness of findings across alternative thresholds. In this single-center retrospective cohort, 3000 adults (≥18 years) undergoing noncardiac surgery between April 2023 and December 2024 were analyzed using data from electronic medical and anesthesia information systems. POH was defined as intraoperative mean arterial pressure (MAP)
