Summary
A prospective randomized double-blind study including patients ASA I-II, aged more than 18
years undergoing surgery under general anesthesia (GA) and endotracheal intubation. Patients
were randomized allocated into 2 groups: ketamine group received ketamine gargle (0.5 mg/kg
up to 30 ml dextrose water) and magnesium group received magnesium sulfate gargle (20 mg/kg
up to 30 mL dextrose water ) 15 minutes before the operation.
Our primary outcome is sore throat and the secondary judging criteria are cough, dysphonia
and satisfaction. A standardized anesthesia protocol was followed for all patients. After
extubation, the patients were asked to grade POST, hoarseness, and cough at 15 min, 1h, and
24 h.
