[Transfer hypokalemia induced by norepinephrine infusion].
We report a case of a severe hypokalaemia by intracellular shift of potassium in a sedated and ventilated head trauma patient. The kalaemia which was 3.9 mmol.L-1 at admission in the intensive care unit decreased to 1.3 mmol.L-1 during a perfusion of noradrenaline (0.3 micrograms.kg-1.min-1). Following the decrease of the noradrenaline dose, and administration of potassium, the kalaemia rapidly increased to 5.3 mmol.L-1 carrying a risk of arrhythmia. Therefore, kalaemia and ECG should be closely monitored when the noradrenaline doses are reduced. The causes of transcellular shift of potassium are reviewed.
