Predicting calcium status post thyroidectomy with early calcium levels.

Objective: The study goals were to predict postoperative normocalcemia and hypocalcemia after total thyroidectomy using calcium levels and to assess the value of a standardized protocol in managing the total thyroidectomy patient.

Study Design: We conducted a prospective study encompassing 68 patients undergoing a total thyroidectomy using a standardized protocol. Blood to measure postoperative calcium levels was drawn at 6, 12, and 20 hours and then twice daily thereafter.
