Liver injury after the intravenous amiodarone administration in patient with impaired heart function

Abstract

While many adverse effects have been associated with long-term oral amiodarone therapy, acute hepatotoxicity from intravenous administration of amiodarone is a rare side effect. This case report focuses on a 78-year-old critically ill female, who underwent several urgent surgical procedures and had elevated liver aminotransferases concentrations after the intravenous administration of amiodarone for the treatment of atrial fibrillation. Also, the patient developed heart failure with reduced left ventricular systolic function. Immediately after the discontinuation of amiodarone therapy, liver aminotransferases levels began to decline. Our case suggests that regular monitoring of hepatic function is required in patients receiving intravenous amiodarone, especially in the setting of impaired heart function and possible liver hypoperfusion.

Key words: amiodarone, hepatotoxicity, heart failure.

Refibrillation during out-of-hospital arrest: A frequent event with clinical consequences

Abstract

The refibrillation was a frequent event in out-of-hospital cardiac arrest (OHCA). The number of recurrences of ventricular fibrillation (VF) is in inverse relationship with survival. In this article we discuss about causes and mechanism of refibrillation. The amiodarone and new technical solution (defibrillators that may allow continuous monitoring of the heart rhythm, while chest compressions continue and recommend defibrillation when refibrillation occurs) are promising new strategy to improve outcome of OHCA and recurrent VF.

Keywords: out-of-hospital cardiac arrest, ventricular fibrillation, defibrillation, refibrillation, amiodarone, continuous monitoring of the heart rhythm
