Objective To mainly investigate the effect of the dexmedetomidine-propofol-sufentanil composite anesthetic in the treatment of spinal deformity surgery, and to provide a reference for clinical optimization of anesthetic management. Methods From October 2025 to January 2026, 76 patients with spinal deformity surgery treated in our hospital were selected as research objects. All subjects were divided into two groups, namely, the control group and the intervention group, each of which consisted of 38 cases, by using a randomized numerical table method. The control group used the anesthetic scheme of propofol combined with sufentanil, and the intervention group used the dexmedetomidine-propofol-sufentanil composite anesthetic scheme. The four core observation indicators of the groups of patients, namely, the anesthesia-related time indicators, the stability of hemodynamic during the operation, the incidence of adverse reactions during the operation and the analgesic after the operation were compared. Results The intervention group was superior to the control group in all indicators (P<0.05). Conclusion The application dexmedetomidine-propofol-sufentanil composite anesthesia in spinal deformity surgery can not only help patients to shorten the time of anesthetic induction and wake-up extubation, but also maintain the stability of hemodynamics during the operation, reduce the incidence of adverse reactions, and improve the analgesic effect after the operation It has high clinical application value.
