Bail-out extracorporeal membrane oxygenation for hydroxychloroquine intoxication: a warning for COVID-19 health-care givers.

This case report describes an intentional intoxication with 18 g of hydroxychloroquine (HCQ) presenting with unconsciousness, ventricular dysrhythmias, cardiogenic shock and pulmonary oedema. Initial treatment consisted of sodium bicarbonate, lipid emulsion, diazepam and norepinephrine. Because of persistent cardiogenic shock veno-arterial extracorporeal membrane oxygenation (V-A ECMO) was successfully used as a bridge to recovery.
