AbstractAcute hyperkalemia is a dangerous electrolyte disorder, which must be treated immediately. It can lead to cardiac arrhythmia and death due to alterations in cell membrane potentials. The resulting alterations in the electrocardiogram (ECG) are multifarious and need to be rapidly recognized. Treatment consists of various stages. In addition to membrane stabilization, which is always necessary, potassium must be displaced into the intracellular space and then eliminated from the body. A commonly applied method for displacement of potassium into the intracellular space involves the administration of insulin-glucose mixtures, which is associated with many complications. In the clinical routine many prescription variations are applied, which do not always appear to be ideal with respect to the individual risk-benefit ratio. A practically useful and easily memorized insulin-glucose mixture has a relationship of 1IU insulin to 4g glucose. The therapeutic elimination from the body is carried out using an enhanced diuresis or the utilization of renal replacement procedures. Special attention must be paid to the continous monitoring of potassium and blood sugar levels. After overcoming the acute situation, attention must be paid to treatment of the underlying disorder and if necessary to readjustment of the long-term medication of the patient.
