With the increase in numbers of surgical patients who are being treated on an ambulatory basis, it is important to develop reliable criteria to identify when patients are ready to go home. A scoring system may speed up discharge. Recent evidence suggests that drinking and voiding are not mandatory discharge criteria, and insisting on them will delay the discharge of patients unnecessarily. Recent research work indicates that certain cases can bypass the Post- Anesthesia Care Unit without compromising safety. Although major complications of ambulatory surgery are rare, pain, nausea, headache, dizziness, and drowsiness are still distressingly common.
