Randomized Controlled Trial
Predicting the need for calcium and calcitriol supplementation after total thyroidectomy: results of a prospective, randomized study.
The optimal protocol for the detection and treatment of postthyroidectomy hypoparathyroidism is unknown. We sought to identify and treat patients at risk for symptomatic hypocalcemia on the basis of a single parathyroid hormone (PTH) obtained the morning after surgery (POD1). ⋯ A single POD1 PTH level <10 can accurately identify those patients at risk for clinically significant hypocalcemia. All total thyroidectomy patients with a postoperative PTH ≥ 10 can be safely discharged without supplementation. Given the small number of patients with PTH <10, it is unclear whether both calcium and calcitriol are needed for these higher-risk patients.
