| Results: The study showed that the incidence of sore throat in the magnesium group was lower than ketamine. Comparison of the three groups at the time of recovery (0), 2, 4, and 24 hours after surgery showed that the differences between the three groups were significant in terms of sore throat. Also, the difference in the incidence of sore throat within each group in the four times in all three groups was statistically significant (P=0.001). There was no statistically significant difference between age, gender, body mass index, heart rate, blood pressure, duration of intubation, duration of surgery and anesthesia, size of laryngoscopy insertion and Cormack and Lehane score in the three studied groups. A drop in systolic blood pressure was observed in the both groups half an hour after the operation, which was statistically significant. Changes in diastolic blood pressure were significant only in the magnesium group. |
