Brief Summary:
To evaluate the analgesic effect of benzydamine hydrochloride dripping on the endotracheal tube cuff for postoperative sore throat.

Condition or disease Intervention/treatment Phase
For Intervention Drug: benzydamine HCl Phase 3

Detailed Description:
The investigators will assign patients into either the benzydamine hydrochloride or the control group. The whole ETT cuff will be either dripped with 3 ml (4.5 mg) of benzydamine hydrochloride or nothing 5 minutes prior to anesthesia induction. The incidence and severity of POST at 0, 2, 4, 6, 12 and 24 hours postoperatively will be assessed. The potential adverse effects of benzydamine hydrochloride (throat numbness, throat burning sensation, dry mouth and thirst) will also be evaluated.
