Anaesthesia for caesarean section in a patient receiving high dose amiodarone for fetal supraventricular tachycardia.

We report the anaesthetic management of a Caesarean section in a woman treated with high dose amiodarone for fetal supraventricular tachycardia. Most of the interactions between anaesthesia and amiodarone therapy previously reported were observed during general anaesthesia. We therefore chose epidural anaesthesia using incremental doses of lignocaine 2% with adrenaline and fentanyl. This technique appeared to be safe, but since severe refractory vasodilation with hypotension may occur, potent vasopressor agents should be immediately available.
