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.

Conditions

• Lower Extremity Surgery
• Upper Extremity Surgery
• Post-operative Pain

Interventions

Type	Name	Description
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.
