Study Arms:
- Magnesium sulfate infudsion (Type: ACTIVE_COMPARATOR): patients will receive IV bolus dose of 40mg/kg magnesium sulfate in 100 ml saline solution over ten minutes then continuous infusion of 10-15mg/kg/h will be titrated till achieve target mean arterial blood pressure (55-65 mmHg) and will be terminated by the end of surgery.
- Labetalol infusion (Type: ACTIVE_COMPARATOR): will receive IV bolus does of labetalol 0.25 mg/kg over ten minutes then continuous infusion of 0.5-1mg/kg/h will be titrated till achieve target mean arterial blood pressure (55-65 mmHg) and will be terminated by the end of surgery.

Based on this trial design, predict the completion outcome and termination type (if applicable).
