Objective: To compare the application of oxelidine in postoperative analgesia after orthopedic lumbar spine surgery with morphine or sufentanil, and to explore the efficacy and safety of postoperative analgesia. Method: Researchers included 90 patients with American Society of Anesthesiologists (ASA) physical conditions I and III, aged 18 to 65 years, who were scheduled to undergo orthopedic lumbar general anesthesia surgery at an appropriate time. The patients were randomly divided into 3 groups, with 30 cases in each group: The oxeridine group (Group A), where a loading dose of 1.5mg of oxeridine was intravenously injected. Ten minutes later, an intravenous analgesic pump of 0.01mg/kg-1.h-1 was connected. Oxeridine was mixed with normal saline to 100ml at a rate of 2ml/h. Morphine group (Group M), a loading dose of 4mg of morphine was intravenously injected. Ten minutes later, an intravenous analgesic pump of 0.03mg.kg-1.h-1 morphine was connected with normal saline to 100ml at a rate of 2ml/h. Sufentanil group (Group S), a 4u loading dose of sufentanil was intravenously injected. Ten minutes later, an intravenous analgesic pump of 0.03ug.kg-1.h-1 was connected. Sufentanil was combined with normal saline to 100ml at a rate of 2ml/h.The resting and exercise VAS pain scores of the three groups of patients at 30 minutes, 2 hours, 6 hours, 12 hours, 24 hours and 48 hours after the operation and adverse reactions within 48 hours were recorded.
