Primary Outcome Measures:
  • The effect of magnesium sulfate on postoperative sore throat after spinal surgery in prone position with tracheal intubation [ Time Frame: Change of post operative sore throat level from 1 to 48 hours after surgery ] [ Designated as safety issue: No ]
    Incidence of post operative sore throat Severity of post operative sore throat (10 cm-visual analogue scale ) Incidence of post operative hoarseness Severity of post operative hoarseness ( four-graded scale, 0= no hoarseness, 1= mild hoarseness, 2= severe hoarseness, 3= aphonia)


Secondary Outcome Measures:
  • The effect of dexamethasone on postoperative sore throat after spinal surgery in prone position with tracheal intubation [ Time Frame: Change of post operative sore throat level from 1 to 48 hours after surgery ] [ Designated as safety issue: No ]
    Incidence of post operative sore throat Severity of post operative sore throat (10 cm-visual analogue scale ) Incidence of post operative hoarseness Severity of post operative hoarseness ( four-graded scale, 0= no hoarseness, 1= mild hoarseness, 2= severe hoarseness, 3= aphonia)

Arms Assigned Interventions
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)
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)
