Physiological changes associated with aging as well as altered drug sensitivity and metabolism place elderly patients at an increased risk of perioperative morbidity and mortality.³³ Bag-mask ventilation may be more difficult in the edentulous patient, and limitations in cervical spine range of motion may make direct laryngoscopy and tracheal intubation more difficult. Elderly patients have an increased incidence of age-related co-morbid conditions as well as diminished organ function and reserve. Common comorbidities include CAD, hypertension, diabetes, CHF, and renal failure. Elderly patients are more sensitive to CNS depressants and are at risk of postoperative cognitive dysfunction and delirium.
