Hypotension, rapid heart rate, and an increased cardiac index are hemodynamic disturbances that can be triggered by a tourniquet's deflation. Patients with impaired cardiovascular function and the elderly are at increased risk due to these changes, even though they may not be noticeable to those with healthy cardiovascular systems.

Vasopressor medications work by reversing the effects of sympathetic blockage on the blood vessels. As a result of their actions, venous return and heart filling are preserved and vascular tone is restored. An effective method for managing spinal hypotension is the administration of vasopressors, either by bolus injections or continuous infusion.

Researchers are interested in studying the efficacy and safety profiles of norepinephrine and glypressin since they have gained increased attention as possible alternatives for the prevention and treatment of hypotensive episodes.
