Background and aim: Sore throat is one of the common difficulties after tracheal extubation, sometimes it continues for 72 hours and many Eatients suffer from it, because general anesthesia y intubation is the most current anesthesia methode in Iran. Studies have shown dexametha-sone is effective for some of the anesthesia side effects, such as stridor, nausea and vomiting. We want to show intravenous dexamethasone is effective in preventation of this kind of sore throat. Materials and methods: This is a clinical trial research. The samples are patients (no= 180), who have been operated under general anesthesia by intubation electively. Selected patients were divided by simple accidental way in two equal groups. Only one group had intravenous dexamethasone injection (0.1 mg/kg). After two hours both group patients were questioned about sore throat and records in questionnaire. Results: After extubation in injection group only 22.2% (20 from 90) and in non injected group 78.9% (71 from 90) shows sore throat. It indicated high effectiveness of dexamethasone as a preventing agent (p<0.001). Sorethroat in relation to age, range of sore throat under 30 years old is higher than others. It indicated to age and sore throat relation (p<0.001). Patients in two groups (injection -non injection) had the same distribution, then all of the age groups shows decrease of sore throat (p<0.001). Conclusion: Intravenous dexamethasone is a preventive agent post extubation sore throat.
