The Analysis of Lumbar Plexus-sciatic Nerve Block in Lower Limb Orthopedic Surgical of Patients by Peripheral Nerve Stimulator

Objective: To investigate the clinical effect of lumbar plexus-sciatic nerve block by peripheral nerve stimulator for patients' lower limb orthopedic surgical.Method: The 70 cases of patients admitted to hospital from June 2010 to December 2011 were randomly divided into two groups,treatment group(n=35) and control group(n=35).The control group was given epidural anesthesia;but the treatment group was given lumbar plexus-sciatic nerve block by peripheral nerve stimulator anesthesia.The anesthesia time parameters,the intraoperative infusion volume,the postoperative VAS score,the incidence of adverse reactions,and the changes of hemodynamic in 2 groups was observed and compared.Result: The onset time of sensory and motor nerve block in the treatment group were significantly shorter than the control group(P0.05);the maintenance time of sensory and motor nerve block in the treatment group were significantly longer than the control group(P0.05);the intraoperative infusion volume and the incidence of adverse reactions in the treatment group was significantly less than the control group(P0.05);the postoperative VAS score in the treatment group was significantly better than the control group(P0.05);the index value of SBP and DBP in T1,T2,T3,T4,T5 in the treatment group was significantly steady than the control group(P0.05).Conclusion: There is a significant clinical effect of lumbar plexus-sciatic nerve block by peripheral nerve stimulator for patients'lower limb orthopedic surgical.
