Effect of Anesthesia with Combined Femoral Nerve and Lateral Femoral Cutaneous Nerve Block on Oxidative Stress And Postoperative Recovery in Lower Extremity Fracture Surgery in Elderly Critically Ⅲ Patients
Objective:To study the effect of femoral nerve combined with lateral femoral cutaneous nerve block anes-thesia on oxidative stress and postoperative recovery of lower limb fracture in elderly critically ill patients.Meth-ods:From June 2022 to June 2023,60 elderly critically ill patients with lower limb fractures were selected and ran-domly divided into control group(using combined spinal-epidural anesthesia)and study group(using femoral nerve combined with lateral femoral cutaneous nerve block anesthesia),with 30 cases in each group.The clinical in-dexes of the two groups were compared.Results:Compared with the control group,the fluctuation range of hemody-namic indexes of T1、T2 and T3 in the study group was lower,the SOD level was higher,and the MDA and NE lev-els were lower,P＜0.05.Compared with the control group,the duration of motor block in the study group was shor-ter,and its cognitive function scores were higher at different time points within 1 day after operation,P＜0.05.The incidence of adverse reactions in the study group was lower than that in the control group,and the satisfaction with surgical anesthesia was higher than that in the control group,P＜0.05.Conclusion:Femoral nerve combined with lateral femoral cutaneous nerve block anesthesia can stabilize hemodynamics,shorten the duration of motor block,accelerate the recovery of cognitive function,reduce adverse reactions and improve anesthesia satisfaction.
