Hyperkaliaemic cardiac arrest in Angelman's syndrome following suxamethonium.

Abstract

We present a case of hyperkaliaemic cardiac arrest in a patient with Angelman's syndrome after administration of suxamethonium in rapid sequence intubation. The patient was admitted to the critical care unit in with aspiration pneumonia and intestinal obstruction. They had a cardiac arrest after suxamethonium administration. Potassium level was remarkably high (11.1 mmol/L). ROSC was achieved after 26 min of CPR and resuscitation. We discuss Angelman's syndrome molecular pathology, especially affecting the potassium channels transmission and its relation to suxamethonium in emergency intubation.
