Calcium resonium

In hyperkalaemia, oral administration or retention enemas of a polystyrene sulphonate resin may be used. A sodium phase resin (Resonium A) should obviously not be used in patients with renal or cardiac failure as sodium overload may result. A calcium phase resin (Calcium Resonium) may cause hypercalcaemia and should be avoided in predisposed patients, e.g. those with multiple myeloma, metastatic carcinoma, hyperparathyroidism and sarcoidosis. Enemas should be retained for as long as possible, although patients rarely manage for...

The commonest form of treatment for acute hyperkalaemia is the infusion of insulin and glucose to move potassium ions into cells. An infusion of calcium gluconate may also be given to counter-aci the effects of hyperkalaemia. Dialysis is fretiticntly necessary to treat severe hyperkalaemia. When there is a slow rise in the plasma potassium this may be stopped or reversed by oral administration of a cation exchange resin such as Resonium A.
