Objective:To study theeffect of ultrasound-guided superficial cervical plexus block combined with general anesthesia on oxidative stress and brain metabolism in patients undergoing carotid endarterectomy.Methods:A total of 128 patients with ischemic stroke admitted to Xingtai Third Hospitalwere selected,and the brain tissue metabolism,oxidative stress and other indicators of the patients were compared.Results:Serum s100-β protein and NSE levels in the observation group were significantly lower than those in control group 1d and 3d after surgery(P<0.05).Serum SOD and TAC in observation group were significantly higher than those in control group 1d,3d and 7d after surgery,while serum MDA in observation group was significantly lower than control group 1d,3d and 7d after surgery(P<0.05).Conclusion:Ultrasound-guided cervical block combined with tracheal intubation general anesthesia in carotid endarterectomy can effectively improve perioperative indicators,correct oxidative stress response,and reduce brain tissue metabolism.
