The Effect of Preoperative Oral Dexamethasone Supplementation on the Outcome of Thyroidectomised Patients.
Summary
Glucocorticoids are well known for their analgesic, anti-inflammatory, immunomodulatory and anti-emetic effects. Recovery time after thyroid surgery may depend on several factors, such as postoperative pain, nausea and vomiting, postoperative sore throat, voice disorders and symptomatic hypocalcaemia (low serum calcium level). However, there is little information in the literature about the preventive use of glucocorticosteroids in patients undergoing thyroid surgery. The aim of the study is to evaluate the clinical impact of preoperative oral dexamethasone supplementation on the surgical outcome in patients with multinodular goiter undergoing total thyroidectomy. Patients will be assigned to the supplementation group and the placebo group. In the supplementation group 8mg of dexamethasone will be administered orally one hour before surgery. In the postoperative period, the frequency and intensity of pain, nausea, vomiting, sore throat and hoarseness will be assessed. The incidence of symptoms of hypocalcaemia will also be evaluted. Preoperative and postoperative levels of vitamin D, cytokines, acute phase proteins and substances related to calcium metabolism will be measured in the blood. Cytokines levels in drainage fluid will also be assessed. The main hypothesis of the study is that in patients with supplementation postoperative discomfort and decrease in serum calcium and parathormone level and hypocalcemic symptoms will be less severe and the levels of proinflammatory substances will be decreased.
