The Aldrete Score has withstood the changes in anesthesia and surgical care that have developed in the past three decades. Nevertheless, it is imperative that (1) a modification is made to incorporate the most effective monitor of the respiratory and hemodynamic functions, e.g., pulse oximetry; and (2) the five indices previously used be expanded by incorporating five more indices including dressing, pain, ambulation, fasting/feeding, and urine output to evaluate patients undergoing ambulatory surgery and anesthesia. A patient's recovery from anesthesia and surgery, using 10 indices graded 0, 1, or 2, would provide criteria for street fitness and discharge to home when the patient reaches a postanesthesia recovery score of 18 or higher.
