Answer

Answer

The geriatric population consumes more systemic medications than any other group. Numerous drug interactions and complications arise in this population, and special attention should be paid to them.

Diuretics are commonly prescribed medications for hypertension, congestive heart failure, and other fluid-retaining states. Common complications of diuretic therapy are hypokalemia and hypomagnesemia. Both abnormal electrolyte states, especially in combination with epinephrine use and a diseased heart, can predispose the patient to unwanted cardiac arrhythmias. In such patients, a baseline potassium and magnesium level prior to surgery may be indicated because these abnormalities are easily corrected with oral potassium and magnesium supplementation.
