 | | Acute renal failure is in fact responsible for at least one-fifth of all perioperative deaths among elderly surgical patients. | | | A major pharmacokinetic consequence of age-related changes in renal function is prolongation of the elimination half-time of anesthetic drugs and any metabolites requiring renal clearance. | | | The aging process results in profound anatomic and functional changes in virtually all major organ systems, including the cardiovascular, respiratory and renal systems. |

| | Serum creatinine and urea concentrations change inversely with changes in GFR and are therefore useful in gauging the degree of renal dysfunction. | | | Hypovolemic conditions which lead to a compensatory decrease in renal blood flow may, if sufficiently severe and/or sudden, lead to acute renal failure from acute tubular necrosis. | | | Changes in serum creatinine concentration more reliably reflect changes in GFR than do changes in serum urea concentrations. |
