Betamethasone to prevent hypocalcemia and other complications after total thyroidectomy: A retrospective case-control study.

OBJECTIVE

Hypocalcemia (HC) is a common complication after thyroid surgery. This retrospective case-control study aimed to evaluate the efficacy of postoperative betamethasone infusion in reducing the incidence of HC following thyroid surgery, with recurrent laryngeal nerve palsy and other complications as secondary outcomes.

MATERIAL AND

METHODS

A total of 196 patients who underwent total or completion thyroidectomy were retrospectively analyzed. Patients were divided into groups receiving postoperative betamethasone infusion or no glucocorticoid treatment. Postoperative data on HC incidence (at least one serum calcium measurement below 8.0 mg/dL), symptomatic HC (HC associate with numbness of the extremities, facial paresthesia, muscular spasms, and Chvostek's or Trousseau's signs), pain, recurrent laryngeal nerve palsy, voice dysfunction, sore-throat and dysphagia were collected and analyzed. Additionally, demographic and clinical characteristics were assessed, including preoperative assessments, intraoperative techniques, and postoperative recovery parameters.

RESULTS

The study found a significantly lower incidence of HC and symptomatic HC in the betamethasone group compared to the control (32.0% vs. 49.5%, p=0.013; 11.3% vs. 25.3%, p=0.012, respectively). Betamethasone-treated patients also reported lower postoperative pain scores (p=0.002).

CONCLUSION

Betamethasone infusion post-thyroidectomy demonstrated efficacy in reducing HC and symptomatic hypoparathyroidism, with minimal impact on other complications. The findings suggest the potential of glucocorticoids as a therapeutic option in thyroid surgery to enhance postoperative outcomes and patient recovery.
