From the Guidelines

Thyroid storm is treated with a combination of medications, including propylthiouracil or methimazole, saturated solution of potassium iodide, dexamethasone, and beta-blockers, such as propranolol, along with general supportive measures.

Treatment Overview

  • The treatment of thyroid storm involves a multi-step approach, including:
    • Anti-thyroid medications: propylthiouracil or methimazole to reduce thyroid hormone production 1
    • Iodine solutions: saturated solution of potassium iodide or sodium iodide to inhibit thyroid hormone release 1
    • Corticosteroids: dexamethasone to reduce T4 to T3 conversion and prevent adrenal crisis 1
    • Beta-blockers: propranolol to control heart rate and tremors, and inhibit peripheral conversion of T4 to T3 1

Supportive Measures

  • General supportive measures, such as oxygen, antipyretics, and monitoring, are also crucial in managing thyroid storm 1
  • It is essential to identify and treat the underlying cause of thyroid storm, and to evaluate fetal status in pregnant women 1

Important Considerations

  • Thyroid storm is a medical emergency that requires prompt treatment to prevent severe complications, such as heart failure, shock, and coma 1
  • The treatment of thyroid storm should be individualized, taking into account the patient's medical history, gestational age, and fetal status 1

From the Research

Treatment Overview

The treatment for thyroid storm (thyrotoxic crisis) is a multifaceted approach that aims to correct the homeostatic decompensation caused by the condition 2. The treatment principles include:

  • Reduction of circulating thyroid hormone levels
  • Inhibition of the peripheral effects of circulating thyroid hormones
  • Supportive care to reverse systemic decompensation
  • Treatment of the underlying precipitating event 3

Medical Treatment

Medical treatment is based on three principles:

  • Counteracting the peripheral effects of thyroid hormones
  • Inhibition of thyroid hormone synthesis
  • Treatment of systemic complications 4 These measures should bring about clinical improvement within 12-24 hours.

Surgical Treatment

Early thyroidectomy should be considered as the treatment of choice if medical treatment fails to result in clinical improvement 4. Therapeutic plasma exchange or thyroidectomy may be necessary for patients who fail medical therapy 5.

Key Considerations

  • Prompt recognition and aggressive treatment are crucial in limiting the morbidity and mortality associated with thyroid storm 3
  • The diagnosis of thyroid storm is made entirely on clinical findings, and any delay in therapy should be avoided 4
  • The mortality rate of thyroid storm is currently reported at 10% 5, and patients who have survived thyroid storm should receive definite therapy for their underlying hyperthyroidism to avoid any recurrence of this potentially fatal condition.
  • A multipronged approach has been recommended and has been associated with improved outcomes 6
