Amiodarone is an antiarrhythmic drug used to treat cardiac tachyarrhythmias. It has many adverse effects, with thyroid dysfunction one of the most notable. ⋯ There are two types of amiodarone-induced thyrotoxicosis: type 1 occurs in those with pre-existing thyroid disease and is treated with thionamide, whereas type 2 occurs in those without and is treated with glucocorticoids. Patients with amiodarone-induced hypothyroidism may be given levothyroxine to replace thyroid hormone, but in some cases, the appropriate management may be cessation of amiodarone.

Adverse effects of perioperative opioids have led to the pursuit of 'opioid-free anaesthesia'. While early studies have shown that effective analgesia can be achieved without using opioids, with some reduction in unwanted effects, further research is needed to elucidate which patients may benefit most and how.
