Abstract：Objective To explore the application value of femoral nerve block anesthesia in knee joint operation in primary hospitals.Methods Sixty patients with knee joint surgery from January 2016 to August 2017 in our hospital were randomly divided into femoral nerve block group (femoral nerve group)and lumbar combined block anesthesia group(control group),30 cases in each group.In the control group,combined spinal-epidural anesthesia was used,while in the femoral nerve group,femoral nerve block anesthesia was applied.The anesthetic effect of two groups performed with knee surgery was compared.The time of analgesia maintenance,hemodynamic indexes before and after intervention,incidence of adverse reactions including nausea and vomiting,and urine retention were compared.Results In the two groups,the anesthetic effects were satisfactory without statistical difference in blocking (P＞0.05).In the femoral nerve group,time to maintain anesthesia was longer than that in the control group(P＜0.05).The hemodynamic indexes before the intervention were similar(P＞0.05),but after anesthesia,the hemodynamic indexes in the femoral nerve group were superior to those in the control group (P＜0.05).The incidence of adverse reactions like nausea and vomiting,and urinary retention in the femoral nerve group was lower than that of the control group(P＜0.05).Conclusion Femoral nerve block anesthesia has a high application value in knee surgery.It can effectively improve the analgesic effect,maintain long-term analgesia and hemodynamic stability,and reduce the occurrence of adverse reactions,which is worthy of promotion and application.
