BACKGROUND Background: It is necessary to develop a flexible and automated intelligent surgical anaesthesia management system since all major hospitals have a good network environment and provide basic hardware support for the operation of surgical anaesthesia information systems. OBJECTIVE Objectives: Based on the actual needs of surgical anaesthesia information system, this paper establishes a surgical anaesthesia information system based on BS three-layer architecture data structure, describes the system development environment, the use of technical methods, and the functions realized by the surgical anaesthesia information system. METHODS Methods: The system clarifies object-oriented (anaesthetist, operating room nurse and system administrator), access rights of different roles, three-layer BS structural features and other related points, and divides it into user management module and anaesthesia management module according to different system functions. And three parts of the surgical management module. RESULTS Results: Through the surgical anaesthesia information management system, the anaesthesiologist can complete the entire anaesthesia procedure including preoperative anaesthesia preparation, anaesthesia scheduling, intraoperative recording, and the like. The operating room nurse can conveniently arrange the operation, record the surgical care record, cost entry, surgical execution and postoperative registration. CONCLUSIONS Conclusion: The system realized the standardized management of the surgical anaesthesia process, improved the anaesthesia efficiency, realized the electronic storage of surgical anaesthesia information, shared the surgical anaesthesia information, and recorded and tracked the management of high plant consumables, which enhanced the hospital information construction.
