title: [Severe hyperkalemia in combination with gastroenteritis in previously colectomized patient].
abstract: Severe hyperkalemia is a life-threatening condition that causes primarily cardiac and muscular dysfunction with potentially fatal consequences. This case report describes a case of severe hyperkalemia (9,1 mmol/l) caused by acute prerenal failure due to dehydration. The severe dehydration was caused by a combination of reduced fluid intake due to gastroenteritis and a hampered capacity for intestinal fluid absorption, due to previous colectomy. The patient developed classic signs of hyperkalemia with electrocardiogram changes and muscular dysfunction.
