Summary
A postoperative sore throat (POST) after tracheal intubation is one of the most common postoperative problems causing dissatisfaction to participants, including sore throat, dry throat, cough, sputum, hoarseness and even dysphagia. Both nonpharmacological and pharmacological measures have been attempted to alleviate the incidence and severity of POST with variable success. Airway inflammation may be important in the pathogenesis of these symptoms in intubated participants but however, there was still no study to investigate the effect of cyclooxygenase-2 (COX-2) for the prevention of POST. So, the investigators' study will be the first one to investigate if perioperatively intravenous (IV) Dynastat injection can be used as a new indication for POST prevention.
