Abstract
Four cases of thyroid crisis are herein reported. The prompt diagnosis and immediate treatment resulted in all 4 patients achieving a complete recovery from the crisis. However, one patient unfortunately died from hypoxic encephalopathy which had been caused by cardiopulmonary arrest during transportation to our hospital. As pointed out in the previous studies, all 4 patients showed signs of cardiac decompensation during the treatment. Based on the findings of these present cases as well as those of previous reports, we would like to emphasize the need for strict hemodynamic monitoring of all patients associated with thyroid crisis. Moreover, we believe that it is extremely important to evaluate the thyroid function when trauma patients demonstrate persistent and unusual tachycardia and pyrexia after the onset of injury.
