Study Details

Study Description

Brief Summary

One of the major side effects of surgery to remove the thyroid gland is transient (lasting for a short time) low calcium levels in the blood, or "hypocalcemia." Low calcium levels can cause symptoms such as numbness around the mouth, tingling or cramping in the hands and feet, severe muscle spasms, inability to breathe, or heart rhythm (heart beat) abnormalities. Severe symptoms are life threatening, so it is important to start the management of these symptoms in the hospital. Treating low calcium levels sometimes require patients to spend a few extra days in the hospital.

The human body needs vitamin D to function and stay healthy. Vitamin D helps the body get the calcium needed to make strong bones and teeth. The purpose of this study is to determine if taking vitamin D before surgery to remove the thyroid gland affects whether or not you may have low calcium levels after your surgery and to test the hypothesis that those who are given the Vitamin D before surgery will have decreased hypocalcemia and a shortened hospital stay.

Arms and Interventions

Arm Intervention/Treatment
Active Comparator: Vitamin D (Calcitriol)

Calcitriol, 1.0ug twice daily for 7 days prior to surgery

Dietary Supplement: Calcitriol
1.0ug twice daily for 7 days before surgery

Placebo Comparator: Control

Placebo pill taken twice daily for 7 days prior to surgery

Dietary Supplement: Control Pill
placebo pill taken twice daily for 7 days before surgery

Outcome Measures

Primary Outcome Measures

  1. Measure of Serum Calcium Levels [2-5 days after surgery]

    Serum calcium levels will be evaluated at routine intervals to identify incidences of hypocalcemia

Secondary Outcome Measures

  1. Evidence of Hypocalcemia [2-5 days after surgery]

    Measuring hypocalcemia symptoms, requirements for IV calcium, and extended hospital stay
