Objective:To observe the efficacy of sciatic nerve block combined with epidural block for treatment of sciatic nerve pain caused by lumbar intervertebral disc herniation.Methods:Patients with lumbar disc herniation(n=59)were divided into two group.Sciatic nerve block combined with epidural block group(group S

n=30)underwent the epidural drugs injection

and sciatic nerve block at the same time according to peripheral nerve stimulatorevoked motor response.The epidural block group(group E

n=29)received the same epidural drugs injection.This two groups were given injection every 7 days and 4 injections for a total treatment.The clinical effect

VAS scores

complication and subjective satisfaction were evaluated.Results:After the treatment

VAS scores of both groups decreased significantly(P<0.05)

and the satisfactory rate in group S were much better than those in group E.Conclusion:Sciatic nerve block combined with epidural block for treatment of lumbar intervertebral disc herniation is an effective method.
