Editor’s Perspective What We Already Know about This Topic What This Article Tells Us That Is New Background Normal blood pressure varies among individuals and over the circadian cycle. Preinduction blood pressure may not be representative of a patient’s normal blood pressure profile and cannot give an indication of a patient’s usual range of blood pressures. This study therefore aimed to determine the relationship between ambulatory mean arterial pressure and preinduction, postinduction, and intraoperative mean arterial pressures. Methods Ambulatory (automated oscillometric measurements at 30-min intervals) and preinduction, postinduction, and intraoperative mean arterial pressures (1-min intervals) were prospectively measured and compared in 370 American Society of Anesthesiology physical status classification I or II patients aged 40 to 65 yr having elective noncardiac surgery with general anesthesia. Results There was only a weak correlation between the first preinduction and mean daytime mean arterial pr...
