Enhanced recovery after surgery (ERAS) is a multimodal and multidisciplinary approach to maintaining physiologic function and improving recovery for surgical patients. The ERAS protocol is based on a range of empirical evidence, and consensus ERAS guidelines for various surgical procedures have been published. The elements of the ERAS protocol include minimal preoperative fasting and carbohydrate treatment instead of overnight fasting; no routine use of preoperative bowel preparation; minimally invasive surgical techniques; standard anesthetic protocol; optimal fluid management rather than generous intravenous fluid administration; prevention and treatment of postoperative nausea and vomiting; active prevention of perioperative hypothermia; multimodal approaches to controlling postoperative pain; and early oral intake and mobilization. Implementation of ERAS shortened hospital stays by 30% to 50% and reduced postoperative complications by 50%. A recent study reported that, when patient compliance with the colorectal ERAS protocol was over 70%, 5-year mortality fell by 42% compared with when compliance was below 70%. Auditing process compliance and patient outcomes are key measures for assisting clinicians implementing the ERAS program. As a perioperativist, an anesthesiologist can play a crucial role in implementing the ERAS program and contribute to protocol establishment, auditing, team education and team leadership. While the ERAS protocol was first implemented for colorectal surgery, as a result of its efficacy, it is now being used in nearly all major surgical specialties.
