Modifications to the postanesthesia score for use in ambulatory surgery

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.
