|The goal of treatment is to restore the calcium and associated mineral balance within the body. Since tetany is a manifestation of low calcium levels, treatment consists of replacing calcium. Intravenous calcium is given initially to promptly restore the calcium levels. The underlying cause of the calcium deficiency must be determined to guide the ongoing treatment. Administration of oral calcium plus vitamin D, which is necessary for absorption of calcium into the bones, may be needed for long-term control of this condition.|
Surgical removal of the parathyroid tumors (parathyroidectomy) to treat hyperparathyroidism can infrequently result in acute dysfunction of the remaining parathyroid glands, causing acute hypoparathyroidism and sudden, severe hypocalcemia. The sudden, extreme hypocalcemia can cause life-threatening tetany and possibly airway obstruction. In these (infrequent) cases, immediate treatment with intravenous calcium and careful monitoring of heart function and airway status are required.
