<br/><br/> Deliberate hypotensive anaesthesia (DH) is a technique in which the arterial blood pressure is reduced in a predictable and controlled manner. The main advantage of this technique is to minimize bleeding and improve the surgical field to achieve better intra-operative conditions and less post-operative complications. Several techniques have been used to produce DH including: direct vasodilators, beta blockers, alpha2 adrenergic agonists, and calcium channel blockers. Nitroglycerin is widely used in induction of hypotensive anaesthesia being a potent direct venodilator at low dose and arteriodilator at high dose reducing both preload and afterload
