The preoperative evaluation of a patient is an essential part of the care provided by an anesthesiologist. Its role is to provide information both to the anesthesiologist, for decision-making and management, and to the patient. The preoperative workup should be tailored to the individual with the goal of obtaining further information regarding a disease state or to provide the necessary treatments. After an overall history and physical examination, a focused exam on the patient’s cardiac risk factors should be assessed for necessity of further evaluation. The physical examination should thoroughly evaluate the patient’s airway for specific risk factors for a difficult airway. Special consideration should be given to patients diagnosed with obstructive sleep apnea, recent upper respiratory infections (URI), and preoperative do-not-resuscitate orders. Management of chronic disease is reviewed; this content is likely to be useful as more anesthesiology groups institute the perioperative surgical initiative supported by the ASA.
