All are used in hyperkalemia except

50 ml of 50% dextrose Dextrose alone It was earlier believed that administration of dextrose alone can cause shift of potassium inside the cells by promoting insulin releases. The administration of hypeonic dextrone alone for hyperkalemia is not recommended for two reasons. - Endogenous insulin levels are unlikely to rise to the level necessary for therapeutic effect. - There is a risk of exacerbating hyperkalemia by inducing hypeonicity. Sodium Biarbonate Sodium bicarbonate was earlier believed to cause movement of potassium inside the cells. It has now been demonstrated that Na Bicarbonate does not cause movement of potassium inside the cells even when infused for 4-6 hrs. Instead. - Sodium bicarbonate causes excretion of potassium from the body. When sodium bicarbonate is administered at a rate designed to alkalinize the urine it enhances urinary K+ excretion. This also benefits in metabolic acidosis.
