Thyroid hormone is a permissive hormone with action throughout the body, and dysregulation of thyroid hormone can have significant clinical effects. It is imperative for the treating physician to have a clear understanding of the presentation and clinical consequences of these abnormalities in order to provide timely and effective treatment. This chapter presents an overview of common thyroid disease in the ICU including sick euthyroid syndrome, thyroiditis, hyperthyroidism, and hypothyroidism. The rare, but life-threatening, conditions, thyroid storm and myxedema coma, are also reviewed, as are initial treatment regimens. Finally, the use of thyroid hormone after brain death is discussed.
