Reference work entry


Potassium homeostasis is vital to maintaining some physiological processes such as cell growth, nucleic acids, and protein synthesis, regulation of cell volume, acid-base balance, enzyme activation, and maintenance of resting membrane potential for cellular excitability. Potassium abnormalities are significant metabolic emergencies in the oncologic ICU patient. They are associated with life-threatening complications, higher mortality rates, and longer length of stay. Cancer patients are at particular risk due to the underlying malignancy, prescribed drugs, chemotherapy and radiotherapy, ICU-related treatment, surgery, and other metabolic impairments. Intensivists must be aware because hyperkalemia and hypokalemia can remain asymptomatic in some patients.
