  27. Management of Thyroid Storm

  28. Thyrotoxicosis • Elevated thyroid hormone • Most common causes: • Graves’ Disease (60-80%) • Hyperthyroidism • Thyroid storm (thyroid crisis) Introduction

  29. Hyperthyroidism ≠ Thyrotoxicosis • Conditions with increased thyroid hormone but normal thyroid function: • Thyroiditis • Thyrotoxicosis factitia Introduction

  30. Represent a hypermetabolic state with increased -adrenergic activity Signs and Symptoms • Hyperactivity, irritability, dysphoria • Heat intolerance and sweating • Palpitations • Fatigue and weakness • Weight loss with increased appetite • Diarrhea • Polyuria • Oligomenorrhea, loss of libido • Tachycardia, atrial fibrillation in the elderly • Tremor • Goiter • Warm, moist skin • Muscle weakness, proximal myopathy • Lid retraction or lag • Gynecomastia * in descending order of frequency

  31. Other Signs: • Chest pain – often w/o cardiovascular disease • Psychosis • Disorientation • Hyperdefacation • Edema Signs and Symptoms

  32. Other Symptoms • Diaphoresis • Dehydration • Fever • Widened Pulse Pressure • Thyromegaly • Graves = nontender, diffuse • Thyroiditis = tender, diffuse • Single nodule or MNG • Thyroid bruit Signs and Symptoms

  33. (Brief) Pathophysiology

  34. Autoimmune Drug-Induced Infectious Idiopathic Iatrogenic Malignant Etiologies

  35. Autoimmune • Graves • Chronic thyroiditis (Hashimoto) • Subacutethyroiditis (de Quervain) • Postpartum thyroiditis Etiologies

  36. Infectious • Suppurativethyroiditis • Postviralthyroiditis • Idiopathic • Toxic MNG • 2nd most common cause of hyperthyroidism Etiologies

  37. Iatrogenic • Thyrotoxicosis factitia • Surgery • Malignant • Toxic adenoma • TSH – secreting pituitary tumor • Struma ovarii Etiologies

  38. Thyroid storm (classically w/ underlying Graves or toxic MNG) can be triggered by: • Infection • General surgery • Cardiovascular events • Toxemia of pregnancy • DKA, HHS, insulin-induced hypoglycemia • Thyroidectomy • Non-adherence to antithyroid medication • RAI • Vigorous palpation of the thyroid gland Etiologies

  39. Anxiety Panic Disorders Delirium Tremens Neuroleptic Malignant Syndrome CHF DM Differential Diagnosis

  40. Septic Shock • Heat Exhaustion/ Heat Stroke • Munchausen Syndrome • Withdrawal Syndromes • Toxicity • Anticholinergics (atropine) • Selective Serotonin Reuptake Inhibitors (fluoxetine) • Sympathomimetics (dopamine) Differential Diagnosis

  41. The Burch-Wartofsky Score • assess of the probability of thyrotoxicosis independently from the level of thyroid hormones • temperature, central nervous effect, hepatogastrointestinal, cardiovascular dysfunctin, and history • > 25 points thyrotoxicosis is possible • > 45 points, probable

  42. Burch – Wartofsky Criteria

  43. In thyroid storm, the diagnosis must be made on the basis of the clinical examination. • Total T4 not measured • variations in serum thyroid-binding proteins alter the ability to interpret results • TFT’s do not distinguish thyrotoxicosis from thyroid storm Workup

  44. Some lab abnormalities in thyroid storm • Hyperglycemia • Hypercalcemia • Hepatic function abnormalities • Low serum cortisol • Leukocytosis • Hypokalemia (in HPP) Workup

  45. CXR • May identify trigger for thyroid storm, ex. CHF or pneumonia • Thyroid scan • Diffuse uptake = Graves • Focal uptake = toxic adenoma Imaging

  46. 12-L ECG • Sinus tachycardia (most common) • AF (often in elderly) • Complete heart block (rare) Other Diagnostics

  47. Prompt institution of treatment • Hook to cardiac monitor • Arrhythmia may convert to sinus only after antithyroidtx • Intubate if profoundly altered sensorium • Aggressive fluid resuscitation (3-5L/d) • Profound GI and insensible losses • Thermoregulation with aggressive TSB and antipyretics • Avoid ASA  decreased protein binding increased fT3, fT4 Critical Care
