Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Dexamethasone group
Drug: dexamethasone
Normal saline 100mL was infused for 10 minutes immediately before anesthesia induction. After tracheal intubation, dexamethasone 8mg was injected, and normal saline was continuously infused at the rate of 10 mg Kg-1 h-1 until the end of surgery. (at the time of skin closure)
Experimental: Magnesium group
Drug: Magnesium Sulfate
Magnesium sulfate 30 mg kg-1 was infused in 100mL normal saline for 10 minutes immediately before anesthesia induction. After tracheal intubation, normal saline 1.6mL ( equivalent volume as Dexamethasone 8mg) was injected, and magnesium sulfate was continuously infused at the rate of 10 mg Kg-1 h-1 until the end of surgery. (at the time of skin closure)
