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

Completed · Phase 4

Conditions studied: Postoperative Pain, Foot Numbness

In brief

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.
