The most rapidly growing segment of the elderly population corresponds to persons age 85 and over. As of 2006, elderly patients accounted for 35.3% of the inpatient and 32.1% of the outpatient surgical procedures occurring in the United States. Because age-related changes occur in each organ system in all elderly individuals, this population merits special consideration when undergoing surgical procedures. Furthermore, there is a high probability that older adults will have multiple chronic medical problems, which may present a complex medication management challenge. This review covers the pharmacologic impact of physiologic changes associated with aging, preoperative assessment, preoperative medication management, delirium and the impact of perioperative medications in the elderly, anesthesia and related medications, and specific drug classes and their use in the elderly surgical patient. Figures show an overview of the management of the elderly surgical patient, and preoperative medication management. Tables list medications that should be avoided in older patients with reduced renal function, drugs that exhibit additive adverse effects, medications with high anticholinergic activity, medications that inhibit and induce the CYP450 system, herbal supplements, 2015 Beers Criteria summary of potentially inappropriate medication use in older adults, drugs associated with postoperative delirium, risk factors for postoperative delirium, and clinical pharmacology of commonly used anesthetic agents.
