The prophylactic effect of intravenous magnesium infusion on postoperative sore throat after thyroid surgery. A randomized clinical trial

The reported incidence of postoperative sore throat (POST) varies widely from 14.4 to 100% with maximum severity at 4 to 6 postoperative hour. Nonetheless, it has increasingly become a common clinical problem particularly in thyroid surgery. Although POST usually resolves spontaneously in few days, it is likely to be the most common complaint. Driven by the increased number of patients with post-intubation sore throat following thyroid surgery, the aim of the present study was to evaluate the effectiveness of perioperative magnesium infusion in attenuating POST after thyroidectomy.
