"BLOOD PRESSURE AND HEART RATE DYNAMICS IN NORMOTENSIVE AND HYPERTENSIVE PATIENTS ADMINISTERED ANGIOTENSIN RECEPTOR BLOCKERS DURING SPINAL ANESTHESIA"

Abstract

Background: Hypotension is the most common complication associated with spinal anesthesia, particularly prevalent in patients with a history of hypertension. Regular use of antihypertensive medications can help mitigate this effect. However, the continuation of drugs that inhibit the renin-angiotensin-aldosterone system on the day of surgery remains a subject of debate. Aims and Objectives: This study aims to examine the intraoperative changes in blood pressure (BP) and heart rate in patients on angiotensin receptor blockers (ARBs) undergoing surgery under spinal anesthesia, comparing the results with those of normotensive patients.
