WHAT SHOULD BE THE APPROACH TO MODERATE HYPOCALCAEMIA IN THE EARLY PERIOD FOLLOWING TOTAL THYROIDECTOMY?

Abstract

It is unclear whether treatment is necessary for transient moderate hypocalcaemia occurring after total thyroidectomy; if it is present, it is unclear which treatment modality should be preferred. To investigate both the necessity and effectiveness of different treatment approaches of oral and/or intravenous calcium treatment in patients with transient, postoperative, moderate hypocalcaemia. This is a case control study made between June 2014 and June 2015. Forty-five patients who had serum calcium levels 6 hours after total thyroidectomy between 7.5-8 mg/dL were divided into three equal groups: an oral calcium administration group, an intravenous calcium administration group and a no-treatment group. Serum calcium and parathyroid hormone levels were measured preoperatively and on postoperative days 1, 2, 5 and 10. For post-thyroidectomy patients with serum calcium 7.5-8 mg/dL in the early postoperative period, no significant difference in serum calcium or parathyroid hormone was detected between groups. Follow-up without treatment seems to be the most effective approach for moderate hypocalcaemia occurring in the early period following total thyroidectomy; this suggests that intravenous treatment should be avoided.
