High-risk populations, particularly elderly individuals and patients with cardiovascular comorbidities, exhibit markedly elevated incidences of postoperative myocardial injury (MINS), acute kidney injury (AKI), and mortality. Intraoperative hypotension (IOH), a pervasive clinical phenomenon affecting 40%-90% of surgical cases, Substantial observational evidence links IOH severity/duration to ischemic organ injuries (MINS, AKI) and long-term morbidity.Nevertheless, inherent limitations of observational designs-particularly residual confounding-preclude definitive causal inferences. Notably, randomized controlled trials (RCTs) investigating goal-directed hemodynamic interventions demonstrate inconsistent clinical benefits, underscoring the imperative to clarify causal mechanisms between IOH and organ injury. This causal ambiguity arises from two unresolved scientific questions: (1) Threshold personalization deficit; (2) Therapeutic strategy limitations. In light of current evidence, perioperative hypotension management demands personalized strategies, the investigators propose a multicenter randomized controlled trial (RCT) that aims to clarify the clinical benefits of individualized blood pressure management.
