Which statement is most accurate regarding hyperthyroid perioperative management and epinephrine use?

• A. Epinephrine is beneficial in thyroid storm, and anesthetics with epinephrine should be given
• B. Epinephrine should be avoided in thyroid storm
• C. No special considerations
• D. Hyperthyroid patients require preoperative thyroid hormone suppression

Answer: (A)

Managing a hyperthyroid patient around surgery centers on controlling the heightened adrenergic state that thyroid hormone excess creates. Thyroid storm or significant hyperthyroidism makes the heart and vessels unusually responsive to catecholamines, so anesthesia plans often include measures to blunt that response, such as beta-blockade, antithyroid therapy, steroids, and careful hemodynamic monitoring. Epinephrine, despite its potent adrenergic effects, can be used in the operating room in a controlled way because its alpha-adrenergic vasoconstriction helps maintain blood pressure and reduce surgical bleeding, and beta-blockade helps temper the heart’s response to excessive catecholamines. The key is cautious dosing and close monitoring to avoid tipping into tachyarrhythmias or hypertensive crises. No special considerations would ignore the reality that hyperthyroid patients have exaggerated sympathetic responses, and saying they need no adjustments oversimplifies the issue. Requiring preoperative thyroid hormone suppression as a blanket rule isn’t accurate either; the aim is a euthyroid state or best possible stabilization with antithyroid drugs and beta-blockade rather than universal suppression before all procedures.
