In this issue of Anesthesiology, we feature a series of articles examining accelerated recovery after surgery. This special issue was guest edited by Henrik Kehlet, M.D., Ph.D., formerly Professor of Surgery at Copenhagen University and now Professor of Perioperative Therapy at Rigshospitalet, Copenhagen University, Denmark, who has spent his career finding new and innovative ways to facilitate the recovery of patients after surgery.
