Objective: To investigate the relationship and significance of serum oxidative stress level in brain tissue injury in sepsis-associated encephalopathy. Methods: 106 patients diagnosed with sepsis with complete data from December 2022 to December 2023 in the EICU of Handan Central Hospital were selected, among which 40 cases of sepsis-associated encephalopathy and 66 cases of no encephalopathy occurred. APACHE II score and SOFA score were obtained on admission in all patients. Serum oxidative stress factors: Superoxide dismutase (SOD), malondialdehyde (MDA), markers of brain damage: S100 calcium-binding protein β (S100β), neuron-specific enolase (NSE) were measured. The correlation between serum oxidative stress factors (SOD, MDA) and brain damage markers (S100β, NSE) in the SAE group was analysed. Results: The APACHE II score, SOFA score and mortality rate of patients in the SAE group were significantly higher than those in the sepsis without encephalopathy group, and the difference was statistically significant (P < 0.05). The levels of serum MDA and brain damage markers (S100β and NSE) in the SAE group were significantly higher than those in the sepsis without encephalopathy group, and the difference was statistically significant (P < 0.05), and the level of SOD was significantly lower, and the difference was statistically significant (P < 0.05).
