Summary: For patients undergoing cardiac surgery who are treated with diuretics, potassium supplementation with potassium-rich foods (eg, raisins, bananas, potatoes) may lead better patient satisfaction and may lead to a shorter hospital stay than potassium supplementation with potassium chloride pills, and without any worsening in serum potassium levels. (While not specifically tested in this study, it also seems a reasonable extrapolation to assume this would apply to other surgical or medical patients treated with diuretics as well).
