Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Magnesium sulfate group
In the magnesium group, patients received MgSO4 30 mg/kg in 0.9% physiological saline (total volume 100 ml) intravenously, for 10 min, and then continuous intravenous infusion of MgSO4 at a rate of 1 g/h during the surgical procedure until the maximum of 3 h.
Magnesium Sulfate

Control group
Controls received 100 ml of 0.9% physiological saline, for 10 min, and then continuous intravenous infusion of saline at a rate of 33 ml/h during the surgical procedure until the maximum of 3 h.
Placebo
100 ml of 0.9% physiological saline, for 10 min, and then continuous intravenous infusion of saline at a rate of 33 ml/h during the surgical procedure until the maximum of 3 h
