 Intraoperative blood pressure management should prioritize the preservation of organ perfusion and oxygen delivery rather than the correction of numbers alone. Care should be mechanism-based, addressing the preload, myocardial contractility, and afterload. In fluid therapy, both over- and under-resuscitation can cause organ dysfunction;the intensity of monitoring and treatment should match the patient and procedural risks, using high-quality standard care for low-risk cases and goal-directed therapy(GDT)for higher-risk patients. Crystalloids are the default, with the formulation tailored to individual pathophysiology. When vasopressors are required, high-risk patients should generally have mean arterial pressure maintained at≥60mmHg, with higher targets considered, for example during laparoscopic surgery―while accounting for each agent’s distinct effects on renal blood flow and cardiac output. Ultimately, organ protection depends on optimizing microcirculatory perfusion and cardiac output, not blood pressure alone;rational, mechanism-driven decisions are key to reducing complications.
