Prevention of decrease in mean arterial pressure of greater than 30% has some basis, but it is important to remember that these data were derived from severely hypertensive, presumably untreated patients. For normotensive and treated hypertensive patients, a wider undocumented margin of safety probably exists. Each patient was visited pre-operatively and the procedure explained and written informed consent was obtained. Complete blood count, blood grouping, blood sugar, bleeding time, clotting time, blood urea,serum creatinine, serum electrolytes(sodium, potassium, chloride), chest x-ray, ECG were done as institutional protocol. The minimum age of the patient was 18 years and the maximum age was 50 years.The mean age of the patients in Magnesium sulphate group is27.22±7.42 years and 26.57±5.75 years in Normal saline group.
