Treatment of Thyroid Storm

Introduction to Thyroid Storm

Thyroid storm requires immediate treatment with a combination of propylthiouracil or methimazole, potassium iodide, beta-blockers, corticosteroids, and supportive care to prevent mortality, as recommended by the American Academy of Family Physicians 1, 2, 3

Thyroid storm is characterized by fever, tachycardia disproportionate to fever, altered mental status, gastrointestinal symptoms, and cardiac arrhythmias, often precipitated by surgery, infection, labor, or delivery, according to the American Academy of Family Physicians 1

The American Academy of Family Physicians recommends methimazole as an alternative option to propylthiouracil for blocking new thyroid hormone synthesis 1
The American Academy of Family Physicians suggests using saturated solution of potassium iodide or sodium iodide to block thyroid hormone release 1
The American College of Cardiology recommends beta-blockers as the first choice for controlling cardiovascular symptoms, with non-dihydropyridine calcium channel blockers as an alternative if beta-blockers are contraindicated 1, 4
The American Academy of Family Physicians recommends dexamethasone to reduce T4 to T3 conversion and treat potential relative adrenal insufficiency 1, 3
The American Academy of Family Physicians suggests providing supportive care, including oxygen therapy, antipyretics, appropriate monitoring, and treatment of precipitating factors 1, 5

The American Academy of Family Physicians recommends the same treatment protocol for thyroid storm in pregnancy, with monitoring of fetal status and avoidance of delivery during thyroid storm unless absolutely necessary 1, 2

The American Academy of Family Physicians advises against delaying treatment while waiting for laboratory confirmation, and warns against administering iodine before thionamides, as this can worsen thyrotoxicosis 1
The American Academy of Family Physicians recommends monitoring for agranulocytosis with thionamides and being vigilant for cardiac complications, such as heart failure 1, 5

The American Academy of Family Physicians suggests planning definitive treatment of the underlying thyrotoxicosis after the acute crisis is controlled, which may include continued medical therapy, thyroidectomy, or radioactive iodine ablation 5
