Anesthetic Considerations in a Patient with Amiodarone-Induced Thyrotoxicosis

Abstract: Amiodarone-induced thryrotoxicosis (AIT) is a rare but serious complication of amiodarone use, especially in patients with severe cardiac disease. We present a patient who developed AIT, following administration of amiodarone for life-threatening ventricular arrhythmias. We discuss the medical management of AIT and anesthetic considerations for management of patients with thyrotoxicosis and severe cardiac disease who require surgery including thyroidectomy.

“…[13] Thionamides, usually with a short course of potassium per chlorate are beneficial, and if no response we can add steroids but the effect of medical therapy may take as long as 4 months to be efficient. [7] Major anti-thyroid drugs are able to temporary control symptoms but all are hepatotoxic especially that treatment requires high doses, steroids can reduce the inflammation but have major side effects, plasmpharesis can provide acute relief of type 2 amiodarone induced thyrotoxicosis but its effect is transient, with higher cost and impossibility of long term use. Radioactive iodine is not feasible in all conditions especially in type 2 because of a low uptake.…”

“…Due to its capability to promptly restore euthyroidism, salvage thyroidectomy can be considered the treatment of choice for those patients presenting with a thyrotoxicosis-driven rapid deterioration of cardiac function and/or malignant arrhythmias. As anesthetic and surgical risks may remain quite high in this setting [ 59 ], a careful risk-to-benefit evaluation should be performed in the individual patient [ 60 , 61 ]. It seems agreeable to have surgery performed by skilled surgeons and only when a multidisciplinary team is available [ 17 , 53 , 54 , 62 , 63 ].…”

“…[21][22][23][24] Anesthetic considerations include meticulous control of blood pressure, heart rate, temperature with awareness of early recognition and treatment of thyroid storm and arrhythmias. 25,26 A large majority of the published cases were performed under general anesthesia, and only few case reports under regional and local anesthesia were described. 27,28 Close collaboration between endocrinologists, cardiologists, endocrine surgeons and anesthesiologists is essential to complete thyroidectomy successfully.…”
