A Study Comparing Continuous Sciatic Nerve Block to Single Shot Sciatic Nerve Block
A Randomized Controlled Trial Comparing Continuous Sciatic Nerve Block to Single Shot Sciatic Nerve Block

The purpose of this study is to compare the incidence of postoperative symptoms of neurologic injury after a single shot infragluteal-parabiceps sciatic nerve block versus a continuous infragluteal-parabiceps sciatic nerve catheter.

Phase 4
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Supportive Care
Foot Surgery
  • Drug: Bupivacaine
    Bupivacaine 0.625% with epinephrine 1:300,000
  • Drug: Ropivacaine
    0.2% ropivacaine 5 ml/hr with a 5 ml bolus/hr.
  • Active Comparator: Single Shot Sciatic Nerve Block
    Single shot sciatic nerve blocks will be performed by resident trainees supervised by faculty.
    Intervention: Drug: Bupivacaine
  • Active Comparator: Continuous Sciatic Nerve Block
    Continuous sciatic nerve block catheters will be performed using an insulated needle connected to the negative lead of a constant current nerve stimulator. The catheter will be advanced under ultrasound guidance. A test dose of 1.5% lidocaine with epinephrine will be injected to confirm catheter placement. All subjects will receive a portable pump. The subjects will follow standard protocol discharge instructions in regards to removing the catheter themselves.
    Intervention: Drug: Ropivacaine
