简要总结
The investigators compared continuous epidural infusion with combined continuous femoral and single-shot sciatic nerve blocks. The primary outcome was the incidence of side effects, and secondary outcomes were pain relief, motor blockade,morphine consumption, and rehabilitation indices.
详细描述
The parcicipants were randomly assingned to epidural infusion group and femoral sciatic block. In epidural infusion group, a lumbar epidural catheter was placed at the L3-4 level using loss-ofresistance procedure. ropivacaine 0.2% and fentayl 2mcg/ml were infused at a rate of 5ml/hr from the end of operation. In femoral sciatic group, the femoral and sciatic nerve are located using ultrasound and 0.2% ropivacain is injected. A catheter is inserted to femoral nerve. From the end of operation, 0.2% ropivacaine was infused through the femoral catheter at a rate of 5ml/hr. The incidence of side effects is measured.

结局指标
主要结局
the incidence of side effects
时间窗: during 5 days after the end of operation
Side effects: The patients were asked to their experience of dizziness, sedation, nausea/vomiting (PONV), and pruritus. Urinary retention: bladder volume was measured by ultrasonography and if the volume was more than 400 mL and if the patient was unable to void spontaneously, single catheterization was performed.
次要结局
- Pain(during 5 days after the end of operation)
- Motor blockade at rest and on mobilization(during 5 days after the end of operation)
