Aging is a natural process of declining organ function and reserve. Census data show that the geriatric population is expected to grow to nearly 30%. More than half of geriatric patients have 1 or more surgical procedures in their lifetimes. Moreover, this is the population at greatest risk of morbidity and mortality with any given complication. There is remarkable variability in health across the age spectrum, from fit to frail and compromised. This variability requires a unique approach to anesthetic delivery and drug dosing on an individual basis to avoid complications such as postoperative cognitive dysfunction and delirium.
衰老乃是器官功能与储备下降的自然过程。人口普查数据显示，老年人口预计将增长至近30%。超过半数的老年患者一生中会接受1次或更多次外科手术。此外，这一人群在出现任何特定并发症时发生发病和死亡的风险最高。从健康到体弱和功能受损，整个年龄范围内的健康状况存在显著差异。这种差异需要一种独特的个体化麻醉给药和药物剂量方法，以避免诸如术后认知功能障碍和谵妄等并发症。
