The investigators aimed to search effect of magnesium Sulfate on extubation quality scores,
recovery and pain in larynx micro surgery. The patients allocated to two groups to receive
magnesium sulfate 30 mg/kg in 100 ml saline infusion (maximum 2g) (Group m) or saline 100 ml
(Group S) before induction of anesthesia. Anesthesia induction performed with propofol 2
mg/kg, rocuronium 0.6 mg/kg, remifentanil 0.5 µg/kg and general anesthesia maintained with
total intravenous anesthesia (propofol 3-7 mg/kg, remifentanil 0.05-0.1 µg/kg/min and O2/air
30/70 mixture) to the all patients. Extubation quality scores, Extubation time, NRS scores
were assessed.
