• Resumen

  • Tremor, sinus tachycardia, agitation, convulsions, supraventricular and ventricular arrhythmias, hypokalaemia, hyperglycaemia and ketoacidosis are the typical features of severe poisoning with β2-agonists. Psychosis and hallucinations are occasionally observed. As severe hypokalaemia can precipitate arrhythmias, it should be corrected as soon as possible by the administration of oral and intravenous potassium (40–60 mmol/hour). If there is no contraindication, propranolol (1–5 milligrams) can be administered by slow intravenous injection to reverse hypokalaemia. Supraventricular tachycardia has been treated successfully with adenosine.
