Under the same-day surgery mode, anesthesiologists play an important role in ensuring patient safety, eliminating medical risks, practicing the concept of enhanced recovery after surgery, and realizing comfortable diagnosis and treatment, and a standardized anesthesia management process is the key to protect patients. Based on the principled suggestions in The Consensus of Chinese Experts on Anaesthesia for Day Surgery, combined with the advanced management experience of day surgery anesthesia at home and abroad, and repeatedly revised through practice, a comprehensive, rigorous, and standardized anesthesia management process for same-day surgery was gradually explored by the First Affiliated Hospital of Dalian Medical University. This paper introduces the process from the aspects of procedure of anesthesia evaluation in same-day surgery, preoperative preparation, standardized intraoperative anesthesia management, postoperative pain management, and prevention and treatment of postoperative complications.
