Ultrasound Guidance Versus Electrical Stimulation for Continuous Popliteal-Sciatic Nerve Blocks

NCT00876681 · Status: COMPLETED · Phase: PHASE4 · Type: INTERVENTIONAL · Enrollment: 80

Last updated 2009-10-08

No results posted yet for this study

Summary

Research study to determine if pain relief following foot and/or ankle surgery is influenced by the technique used to place perineural catheter. The catheters are placed using ultrasound-guidance or nerve stimulation and the method is selected at random using a computer program. This may help to determine if one of these methods is associated with an increased success rate and incidence of foot numbness during the infusion.

Conditions

  • Postoperative Pain
  • Foot Numbness

Interventions

PROCEDURE

Popliteal catheter placed via ultrasound or electrical stimulation

Patients will be randomized to one of two groups: Popliteal-sciatic catheter placed via ultrasound-guidance or placed via electrical stimulation. All patients will be given 40ml of 1.5% mepivicaine prior to surgery and then given a pain pump after surgery containing 0.2% ropivacaine. The patients pain scores will be assessed just prior to surgery and the day following surgery. The time of catheter placement and numbness the patient is experiencing in their foot and toes is also assessed and recorded by research staff.
