Strategies for managing perioperative hypertension.

Acute perioperative hypertension is associated with a higher risk of perioperative myocardial ischemia, bleeding, stroke, and renal failure. The immediate concern of short-term antihypertensive therapy is to prevent excessive surgical bleeding from arterial anastomoses, myocardial ischemia, and neurologic complications while causing minimal adverse effects until oral therapy can be resumed. This article reviews perioperative hypertension emergencies/urgencies and various approaches for management.
