The purpose of this study is to determine whether a brief course of SSKI (saturated solution of potassium iodide) administered preoperatively provides any benefit in the surgical management of patients undergoing thyroidectomy as definitive management of their Graves Disease.

Primary Outcome Measures:
  • Blood Loss During Surgery [ Time Frame: up to 162 minutes ]
    Blood loss in milliliters during surgery.

Enrollment: 36
Study Start Date: April 2005
Study Completion Date: April 2013
Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Potassium Iodide
8 drops of Potassium Iodide in a glass of water, by mouth, daily for 7 days prior to operation.
Drug: Potassium Iodide
8 drops of Potassium Iodide in a glass of water taken daily for 7 days prior to thyroidectomy. This is the current standard of care.
Other Name: SSKI
No Intervention: No Treatment
The experimental group receives no treatment.

Detailed Description:

Historically Potassium Iodide was given to patients for 1 week prior to thyroidectomy. This common practice was used to decrease thyroid function and prevent thyroid storm during the thyroidectomy. However, in modern practice, nearly all patients presenting for surgical management have been made euthyroid through the use of medications such as propylthiouracil. Despite this potassium iodine continues to be administered with the presumption that it decreases the friability of the gland making surgery easier, with less blood loss.

The outcomes to be measured in this surgery are operative time, operative complications and blood loss.
