Similarly he requires potassium, and serious manifestations may be expected when a depletion of potassium exists. The theoretical and clinical basis for potassium administration has been well established by other observers.1 With the use of the flame photometer, potassium studies on surgical patients were begun in January of 1950. For the first four months routine daily potassium levels were obtained on practically all surgical patients.
