Although a potassium deficit is present in all cases of volume depletion, it is not usually clinically significant; few patients with moderate dehydration require supplemental potassium. However, failure to correct for hypokalemia during volume repletion may result in clinically significant hypokalemia.

Add potassium to fluids when the patient has documented hypokalemia. For all other patients, avoid adding potassium to fluids until the patient has received resuscitation and has demonstrated adequate urine output.
