Slow induction with sevoflurane was associated with complete atrioventricular block in a child with hypertension, renal dysfunction, and impaired cardiac conduction.

We describe the appearance of complete atrioventricular block (CAVB) with sevoflurane and nitrous oxide during the slow induction in a ten-year-old male patient with hypertension, renal dysfunction, and impaired cardiac conduction. Sinus rhythm was restored following the washout of the anaesthetic gas. And CAVB recurred after the subcutaneous injection of lignocaine. The present report shows that sevoflurane should be treated with care like other inhalational anaesthetics as regards the effect on cardiac conduction.
