Background: Single, low dose perioperative dexamethasone is safe and beneficial but common timing of administration does not maximize effectiveness. IV dexamethasone improves quality of recovery in patients undergoing laparoscopic cholecystectomy and provides a potential 1.5 mm improvement in VAS pain scores in the first 6 hours post mastectomy, which is of questionable clinical significance. A study to determine if dexamethasone improves the quality of recovery in patients undergoing breast surgery is needed in order to provide evidence for change of practices and pre-operative oral dexamethasone offers the potential for routine, low cost administration without uncomfortable side effects.
