The increasing frequency of surgical interventions in the elderly population poses significant challenges in modern anesthesiology, requiring a highly specialized clinical approach. Anesthetic risks in older patients are not merely a function of chronological age but are fundamentally linked to the depletion of physiological reserve and structural involution within vital organ systems. Aging leads to increased vascular rigidity and decreased myocardial compliance, significantly elevating the likelihood of intraoperative hemodynamic instability and myocardial infarction. In the respiratory system, the loss of lung elasticity and weakened protective airway reflexes heighten the risk of postoperative pneumonia and respiratory failure. Perhaps the most concerning complication is related to the central nervous system: postoperative delirium, characterized by acute confusion, affects approximately 15–50% of elderly patients, leading to prolonged hospitalization and increased mortality. Furthermore, age-related declines in hepatic and renal function impair the clearance of anesthetic agents, increasing the risk of drug toxicity and delayed emergence from anesthesia. The prevalence of comorbidities—diabetes, hypertension, and dementia—combined with polypharmacy, complicates the pharmacological profile and increases the potential for dangerous drug interactions. To mitigate these risks, meticulous preoperative assessment is essential, following the “start low, go slow” principle in drug titration. Preference is often given to regional anesthesia over general anesthesia when feasible to preserve cognitive function and reduce systemic stress. Ultimately, successful anesthesia in the elderly is an intricate balance of maintaining fragile homeostasis while managing the multifaceted physiological decline inherent in aging, requiring a multidisciplinary strategy for optimal outcomes.
