Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

The investigators are performing this study to determine if supplementation with calcium and calcitriol (vitamin D) before surgery decreases the rate of hypocalcemia (low calcium) after surgery. Postoperative hypocalcemia (low calcium) is the most common complication after thyroidectomy. Symptoms range from numbness/tingling around the mouth and fingers to severe problems such as low blood pressure, irregular heartbeat, muscle cramps and uncontrollable muscle spasms. The current standard of practice at Lahey for patients undergoing total thyroidectomy is to start Tums 1500mg three times daily and Calcitriol 0.25mcg twice daily immediately after surgery. Also current practice is for each patient to have their calcium and albumin levels checked at 8 hours and 24 hours after surgery. If the corrected calcium level drops below 8.5 or they exhibit symptoms of hypocalcemia the dose of the Tums and Calcitriol are increased per protocol. All patients must also follow up in 3-4 days to have their calcium and albumin levels rechecked. The investigators propose to change the above standard practice at Lahey by making only one change. The investigators wish to start Tums and Calcitriol 5 days before surgery, as opposed to after surgery. This will be the only change to the current standard of care at Lahey. The investigators hypothesize that initiating Tums and Calcitriol supplementation in the preoperative period will decrease the overall rate of postoperative hypocalcemia and its related symptoms. This will possibly decrease length of hospital stay, decrease cost, and prevent any serious complications associated with low calcium.
