Near-fatal betaxolol self-poisoning treated with percutaneous extracorporeal life support.

We present a case of successful treatment of near-fatal beta-blocker self-poisoning but requiring extracorporeal circulatory support with severe complications. A 38-year-old woman ingested a mixture of tablets including betaxolol (5.32 g). Despite intensive treatment with fluid, dobutamine, isoprenaline, epinephrine, nor-epinephrine and glucagon, sustained cardiogenic shock occurred with almost complete hypokinesia of the left ventricular 14 h later. Therefore, a cardiac support was performed with a percutaneous cardiopulmonary bypass device at bedside. We review the literature with emphasis on both the best time to start this technique and its complications.
