This chapter describes guidelines for perioperative hypertension management. Hypertension is a global health problem leading to devastating sequel like coronary artery disease, congestive heart failure (CHF), stroke, renal failure and even death if not managed timely. Perioperative management of high blood pressure (BP) based upon scientific evidence is crucial for all anesthesiologists. This chapter covers the management of hypertension, treatment of hypertension, controlled hypertension for elective surgery, intraoperative HT, management of hypertension in post anesthesia care unit (PACU), hypertensive crisis (HTN-C), and undiagnosed pheochromocytoma for other surgeries. Hypertensive crisis refers to severe elevation in BP of more than 180/120 mm Hg with the presence (hypertensive emergency) or absence of impending or progressive target organ damage (hypertensive urgency) HTN-C effects 7% of patients with essential hypertension and has high 1-year mortality rate of 79%.
