Perioperative hypertension

Perioperative hypertension is an acute, sustained elevation in systemic blood pressure—often characterized intraoperatively by an increase greater than 20% over baseline or postoperatively by blood pressure exceeding 160/90 to 190/100 mmHg—occurring during the preoperative, intraoperative, or immediate postoperative period It primarily affects adult surgical candidates and patients undergoing cardiac or major noncardiac surgeries, frequently impacting the cardiovascular, cerebrovascular, and ren...

It primarily affects adult surgical candidates and patients undergoing cardiac or major noncardiac surgeries, frequently impacting the cardiovascular, cerebrovascular, and renal systems Pathophysiologically, the condition is driven by intense sympathetic nervous system and renin-angiotensin-aldosterone axis activation triggered by surgical stress, endotracheal intubation, visceral stimulation, emergence excitement, pain, hypothermia, or intravascular hypervolemia, which collectively elevate syst...

Pathophysiologically, the condition is driven by intense sympathetic nervous system and renin-angiotensin-aldosterone axis activation triggered by surgical stress, endotracheal intubation, visceral stimulation, emergence excitement, pain, hypothermia, or intravascular hypervolemia, which collectively elevate systemic vascular resistance and myocardial oxygen demand
