 44 y/o patient with Graves’ Dx  Recently cleared for total thyroidectomy  The surgical H&P:  AF VSS WNL RRR no m/r/g CTAB

 Vitals: /86 26  Agitation  Scleral icterus  Bilateral crackles with expiratory wheezing  Palpitations  Mild diaphoresis and nausea without emesis  No obstruction of airway 2 /2 goiter

 Thyrotoxic vs. Thyroid Storm  Life-threatening complication Mortality with Tx 8% or below  Most cases occur post-op Within 6-18 hrs Why? Pre-op Tx necessary?  Si/Sx varied but consider… Hyperdynamic Metabolism  SITT DD are common triggers  Burch and Wartofsky Score ≥ 45 highly suggestive of thyroid storm ≤ 25 thyroid storm unlikely

 Temp: points points ≥ points  Tachycardia points points points ≥ points  A. Fib Absent 0 points Present 10 points  Precipitating Event Absent 0 points Present 10 points  CHF Absent 0 points Mild (pedal edema) 5 points Moderate (bb rales) 10 points Severe(pulm edema) 15 points  CNS Absent 0 points Mild 10 points Moderate 20 points Severe 30 points  GI-Hepatic Absent 0 points Moderate 10 points Severe 20 points

 Pre-op euthyroidism Goiter? Patients with tachycardia and HTN  consider cancellation  Iodide Sodium Iodide, Iopanoic acid, Lugol’s solution ○ Block the release of hormone ○ Wolff-Chaikoff effect  Beta-Blocker  Cortisol Adrenal function?  Thionamides PTU favored for decrease in peripheral conversion  Cholestyramine  Temp control  Hydration With or without glucose?

 Nerve damage Superior Laryngeal ○ Motor to Cricothyroid mm.  aspiration Recurrent Laryngeal ○ Everything laryngeal except Cricothyroid  Hoarseness, stridor, total airway obstruction  Hypoparathyroidism Laryngospasm  Hypothyroidism  Tracheal Compression
