Ultrasound Guidance Versus Electrical Stimulation for Perineural Catheter Insertion

Phase 4

Completed

• Conditions: Postoperative Pain

• Registration Number: NCT00877266
• Lead Sponsor: University of California, San Diego

Brief Summary

This research study is to determine the relative times for perineural catheter placement with the use of ultrasound versus electrical stimulation. The perineural catheter is placed next to the nerves through which local anesthetic is placed to provide pain control following surgery. This study may determine if one method is associated with increased success rate and patient comfort.

Detailed Description

Primary Specific Aim: To determine if the relative times for perineural catheter placement with the use of ultrasound versus electrical stimulation.

Hypothesis: Compared with the use of electrical stimulation, the use of ultrasound guidance when inserting a perineural catheter is associated with a decreased time of placement.

Secondary Specific Aim: To determine if other possible benefits of perineural catheter placement associated with the use of ultrasound guidance versus electrical stimulation.

Hypothesis: Compared with the use of electrical stimulation, the use of ultrasound guidance when inserting a perineural catheter is associated with an increased surgical block success rate and catheter-placement success rate, as well as decreased patient discomfort and incidence of venous puncture.
