[Successful resuscitation of a patient with hyperkalemic cardiac arrest by emergency hemodiafiltration].

The combination of spironolactone with an ACE inhibitor for patients with heart failure may cause severe hyperkalemia. We report the case of a female patient, who developed hyperkalemic (11.4 mmol/l) cardiac arrest probably induced by combined spironolactone and ACE-inhibitor therapy. She was treated successfully by hemodiafiltration under on-going resuscitation which resulted in restoration of spontaneous circulation within 30 min of starting CPR. She was discharged 2 weeks later without any residual neurological effects.
