The Surgical Anesthesia Management System (OANMS) is developed for the anesthesiology department, operating room, and surgical wards. It is used to manage information related to surgery and anesthesia, realizing automatic data collection, automatic report generation, and electronic medical records, and is an important part of the hospital information system. Focusing on the perioperative period, the system intelligently manages each stage of the surgical process, highly integrates information resources from various departments, realizes a paperless surgical anesthesia process, and provides an overall solution for comprehensive informationization of the operating room. The system automatically integrates patient information from HIS, LIS, RIS, and PACS, collects data from monitoring and other equipment, and automatically generates electronic documents according to quality control requirements, freeing anesthesiologists from heavy document recording so they can devote more time to ensuring the smooth progress of surgery.
