Perineural Catheter Insertion Distance for Continuous Peripheral Nerve Blocks

Phase 4

Completed

• Conditions: Lower Extremity Surgery; Upper Extremity Surgery; Post-operative Pain
• Interventions: Procedure: Sciatic catheter left 0-1cm past needle tip vs. 5-6cm past needle tip

• Registration Number: NCT00997867
• Lead Sponsor: University of California, San Diego

Brief Summary

This is a research study to determine if the effects of continuous peripheral nerve blocks are influenced by the distance of insertion past the needle tip of the perineural catheter.

Detailed Description

Specific Aim: Research study to determine the relationships between perineural catheter insertion distance and subsequent continuous peripheral nerve block effects.

Hypothesis: during ultrasound-guided perineural catheter placement, inserting the catheter 0-1cm past the needle tip is associated with decreased postoperative pain compared with inserting the catheter 5-6cm past the needle tip.

Arm && Interventions

Group	Intervention	Description
Catheter 0-1cm past needle tip	Sciatic catheter left 0-1cm past needle tip vs. 5-6cm past needle tip	Patients will be receiving a sciatic (popliteal), femoral, or interscalene nerve block and will be randomized to having the catheter placed 0-1cm past the needle tip. The patient will be called the following day by research staff to assess their post-surgical pain.
Catheter placed 5-6cm past needle tip	Sciatic catheter left 0-1cm past needle tip vs. 5-6cm past needle tip	Patients will be receiving a sciatic (popliteal), femoral, or interscalene nerve block and will be randomized to having the catheter placed 5-6cm past the needle tip. Patients will be called the following day by research staff to assess their post-surgical pain.

Primary Outcome Measures

Name	Time	Method
Average pain in the three hours previous to a phone call the day following surgery as measured on a numeric rating scale (0-10, 0=no pain, 10=worst imaginable pain).	Day 1 after surgery, 3 hours prior to phone call
