ReviewSick euthyroid syndrome. What to do when thyroid function tests are abnormal in critically ill patients.
Abnormal thyroid hormone concentrations are common in patients with serious nonthyroidal illnesses. Early evidence suggests that thyroid hormone levels may predict the prognosis for some patients. Abnormal thyroid function is usually reversible, but thyroid function tests should be repeated when the nonthyroidal illness is resolved. Whether active intervention using thyroid hormone supplements is beneficial or not remains controversial and requires future large-scale investigation.

Some patients die shortly after the onset of an acute illness, despite the best of care. However, a well-led well-organized approach during the first 10 minutes of care can greatly improve the chances of survival and minimize subsequent morbidity. Early treatment should emphasize proper airway management, adequate intravenous access, and a thoughtful approach to the use of medications.
