Clinical Trial 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.


Clinical Trial 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. ;


Study Design

Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Single Blind (Subject), Primary Purpose: Treatment
