Comparison of intraoperative arterial blood pressure lability during general anaesthesia in masked, uncontrolled hypertensive and adequately controlled hypertensive patients: a prospective observational study

Abstract

Intraoperative arterial blood pressure (BP) labil ity refers to deviations beyond the accepted physio logical range or to rapid changes in arterial BP that commonly occur during anaesthesia in noncardiac surgery [1,2]. The presence of BP lability alerts the anaesthetists to potentially deleterious condi tions, such as hypovolaemia, inadequate depth of anaesthesia, and the potential for cardiovascular complications. Intraoperative BP lability has been
