Hypotensive anesthesia first introduced by Gardner in 1946 is a voluntary method of reducing blood pressure during the intraoperative time for providing a clean surgical field, improving visualization, reducing blood loss, and also reducing intraoperative time. This is done by using different drugs including inhalational anesthetic agents, beta-adrenergic antagonists, calcium channel blockers and directly acting vasodilators like nitroglycerin and sodium nitroprusside. Hypotensive anesthesia is a method used in surgeries to decrease blood pressure voluntarily and predictably. It is commonly applied to reduce blood loss and the consecutive need for allogeneic transfusions, also avoiding the resulting transfusion reactions. This also reduces the surgical field visualization and reduces the operating time. This literature review discusses the methods of providing hypotensive anesthesia and their uses in oral and maxillofacial surgery.
