The anesthetic work of day surgery should be guided by the standardized perioperative evaluation system. The evaluation methods and standards with strong operability and repeatability are the prerequisites to ensure the safety and efficiency of day surgery. For the assessment of patients’ preoperative physiological status, preoperative preparation and postoperative rehabilitation, standardized work procedures should be established to ensure patients’ medical safety to the greatest extent. Through summarizing the advanced management experience of day surgery anesthesia at home and abroad, and combining with the principled suggestions in The Consensus of Chinese Experts on Anaesthesia for Day Surgery, the First Affiliated Hospital of Dalian Medical University has repeatedly revised the perioperative anesthesia evaluation methods in practice, and gradually explored a comprehensive, rigorous and standardized perioperative anesthesia evaluation system. This paper will focus on the evaluation of perioperative anesthesia and postoperative follow-up procedures in day surgery.
