Preoperative optimization for a patient with hyperthyroidism to reduce perioperative risk includes which of the following?

• A. Achieving a euthyroid state (often with antithyroid drugs and beta-blockers)
• B. Proceeding with surgery without optimization
• C. Reducing TSH to undetectable levels with thyroid hormone therapy
• D. Initiating chronic lithium therapy

Answer: (A)

Preoperative optimization of hyperthyroidism centers on achieving a euthyroid state to minimize perioperative risk, especially the danger of thyroid storm and dangerous cardiovascular instability under anesthesia. The best approach uses antithyroid drugs to suppress new thyroid hormone synthesis and release, typically methimazole or propylthiouracil, bringing circulating hormone levels down before surgery. Pairing this with beta-blockers rapidly controls adrenergic symptoms like tachycardia and tremor and also reduces peripheral conversion of T4 to the more active T3, further stabilizing the patient’s hemodynamics. In urgent situations, iodine preparations can acutely inhibit hormone release, but the long-term goal remains euthyroidism achieved with these medications and sympathetic blockade. Using thyroid hormone to push TSH down would worsen thyrotoxicosis, and lithium therapy is not a standard or appropriate strategy for preparing hyperthyroid patients for surgery.
