Modifications in anesthesia for geriatric patients
The volume of geriatric surgery is expected to increase dramatically by 2020, requiring a more widespread appreciation of the unique risks and challenges of anesthesia in the elderly. Changes in pharmacokinetics along with age-related changes in organ function have important implications for patient monitoring and dosing of anesthetic, analgesic, and sedative medications. Preoperative screening for risk of postoperative morbidity is improved with an assessment of activities of daily living, and regional anesthesia may be considered to reduce the risk of postoperative delirium, although this remains controversial. Specific homeostatic parameters should be closely monitored in the perioperative period. The approach to anesthesia in geriatric patients should not be merely extrapolated from younger patients, and further evidence specific to geriatric anesthesia will improve surgical outcomes.
