Serum potassium in stage 5 CKD patients on their first presentation in a dialysis service of a county hospital in western Romania.
ABSTRACT CKD patients present deficient elimination of potassium. Ambulatory treatment with hypotensors, mainly angiotensin-renin system inhibitors, can be associated in these patients with potassium retention and risk of hyperkalemia. In pre-dialysis stage-5 CKD patients, the use of medication accompanied by hyperkalemia increases risks of developing it. Using diuretics like spironolactone also increases this risk. Serum potassium can also increase in case of inappropriate consumption of potassium-rich food (bananas). Since ambulatory care does not always rigorously control hyperkalemia in CKD patients we consider it is useful to screen patients when they are referred to dialysis services. The screening can reflect the management of ambulatory CKD patients under treatment with ACE-I and ARB hypotensors. We remark that beta-blockers are attributed a (limited) role in increasing the values of serum K.
