Perioperative hypertension

Intraoperative and immediate postoperative severe hypertension is usually associated with systemic vasoconstriction with relative intravascular hypovolemia. It is generally best treated with a vasodilator ( Ha.!p.ern.199.5). In patients with ischemic heart disease, it is important to limit heart rate to avoid increased myocardial ischemia. Nitrovasodilators are generally first-line therapy for perioperative hypertension. Intravenous b-blockers can be cautiously used to control heart rate, recognizing that they can also depress myocardial contractility. Other options include dihydropyridine or calcium-channel blockers such as nicardipine or isradipine.
