  Purpose

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.


Condition Intervention Phase
Lower Extremity Surgery
Upper Extremity Surgery
Post-operative Pain
 Procedure: Sciatic catheter left 0-1cm past needle tip vs. 5-6cm past needle tip
 Phase 4

Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Single Blind (Subject)
Primary Purpose: Treatment
Official Title: Perineural Catheter Insertion Distance for Continuous Peripheral Nerve Blocks

Primary Outcome Measures:
  • 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). [ Time Frame: Day 1 after surgery, 3 hours prior to phone call ] [ Designated as safety issue: No ]

Estimated Enrollment: 350
Study Start Date: November 2009
Study Completion Date: October 2010
Primary Completion Date: October 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Catheter 0-1cm 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.
 Procedure: Sciatic catheter left 0-1cm past needle tip vs. 5-6cm past needle tip
Patients undergoing orthopedic surgery who are getting a perineural catheter will be randomized to one of two groups: catheter tip placed 0-1cm past needle tip or catheter tip placed 5-6cm past needle tip. Patients will be called by research staff the day following surgery to assess their post-surgical pain using a numeric rating scale.
Active Comparator: Catheter placed 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.

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.
