The document discusses Enhanced Recovery After Surgery (ERAS), a program that aims to safely allow patients to return to daily living as quickly as possible after surgery by decreasing complications and length of hospital stay. ERAS, also called fast-track surgery programs, modifies physiological and psychological responses to surgery. The goal is to improve outcomes and reduce costs without compromising care. Patient factors, quality of care during surgery and recovery, and random healthcare variations can all influence surgical outcomes. The document lists recommended intraoperative practices for ERAS in colorectal surgery. It also discusses several postoperative analgesic options.
