ADVICE

Think Thyroid With Cold, Slow, Low Patients

  • Consider decompensated hypothyroidism when hypotension, bradycardia, altered mental status and bradypnea coexist.
  • Order thyroid tests and bundle cortisol early if the pattern fits.
INSIGHT

Replace 'Myxedema Coma' With A Better Term

  • Abandon the term "myxedema coma" because it misleads bedside recognition.
  • Use "decompensated hypothyroidism" to capture varied presentations and end-organ dysfunction.
ADVICE

Bundle Tests When Suspecting Thyroid Crisis

  • If you suspect a thyroid emergency, send TSH and free T4 and include a random cortisol and metabolic panel.
  • Also get ECG, blood gas, cardiac enzymes, BNP and POCUS to guide management.
