Nowadays, people generally do not know much about anesthesia, including most non-anesthesia doctors, and they simply understand anesthesia as pain relief. It is true that anesthesia is inseparable from pain relief, but it is definitely not pain relief alone. The history of anesthesia has gone through three stages: 1. Pain relief: In the mid-19th century, the emergence of ether. 2. 2. Safety: how to reduce the mortality caused by anesthesia. Most hospitals now achieve anesthesia-related mortality of 1/100,000-200,000 3. Comfort and prognosis: good anesthesia implementation improves surgical prognosis. We anesthesiologists no longer simply relieve the patient’s pain, but more ensure that the patient’s surgery is performed safely, and through our management of the patient to achieve a good prognosis for their comfort. The implementation of anesthesia for a patient usually requires: Stage 1: Detailed preoperative evaluation – taking a medical history, physical examination, understanding the ancillary tests and completing the required examinations Stage 2: Intraoperative management – developing an anesthesia plan, anticipating and targeting possible intraoperative situations. The third stage: postoperative visit – good postoperative analgesia and prevention of possible complications. This is why with good anesthesia management, surgery has grown so much, such as the current development of multiple organ transplants.
