Problem of hyponatremiaProblem of hyponatremia
Hyponatremia is ususal in case of diabetic Hyponatremia is ususal in case of diabetic ketoacidosis. This is due to hyperglycemia. ketoacidosis. This is due to hyperglycemia. The real natremia can be calculated by the The real natremia can be calculated by the following formula:following formula:
NaNacc = Na = Namm + ((Glycemia + ((Glycemia g/lg/l – 1) x 1.6) – 1) x 1.6)
Do not try to correct this false hypoDo not try to correct this false hyponatremianatremia
