Which management approach is most appropriate for thyroid storm?

• A. IV benzodiazepines alone are sufficient
• B. Immediate thyroidectomy is first-line
• C. Aggressive cooling, beta-blockade, and antithyroid drugs
• D. High-dose steroids alone

Answer: (C)

Thyroid storm requires rapid, multi-pronged management that tackles fever, sympathetic overactivity, and ongoing thyroid hormone production. The best approach combines aggressive cooling to lower dangerous hyperthermia, beta-blockade to blunt tachycardia and tremors and to reduce peripheral conversion of T4 to the more active T3, and antithyroid drugs to stop new hormone synthesis and release from the gland. Cooling helps protect organs from heat-related injury, the beta-blocker cuts the excessive adrenergic drive that fuels many manifestations of the storm and, importantly, decreases conversion of thyroid hormones in the body, while antithyroid medications shut down the source of excess hormones. Propylthiouracil is often preferred early because it both suppresses synthesis and reduces peripheral conversion, though other antithyroid drugs that block synthesis can also be used. Steroids are typically added to address potential adrenal insufficiency and further inhibit peripheral conversion, but they do not replace the need for cooling, beta-blockade, and hormone suppression. In contrast, therapies like benzodiazepines alone don’t address hormone production or the hypermetabolic state, immediate thyroidectomy isn’t first-line in an acute crisis, and steroids alone don’t control the storm without the other measures.
