Magnesium Sulfate in Surgical Stress Attenuation Postoperative Sore Throat and Stress Response Induced Tracheal Intubation

Magnesium sulfate has many mechanisms of action for attenuating the stress response as inhibition of catecholamine releasing from the adrenal medulla, keeping the plasma concentration of epinephrine at a fixed level, decreasing the circulating norepinephrine level when compared to that of a control group\[ and also has a vasodilation effect on systemic and coronary blood vessels by blocking calcium ion in vascular smooth muscle.-Methyl- D-Aspartate (NMDA) antagonism is an amazing recent discovery for magnesium sulphate to play an important role in stress response. In this study, we will study the effects of nebulized magnesium sulfate on hemodynamics during intubation.
