Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type ACTIVE_COMPARATOR

Sciatic catheter left 0-1cm past needle tip vs. 5-6cm past needle tip

Intervention Type PROCEDURE

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.

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.

Group Type ACTIVE_COMPARATOR

Sciatic catheter left 0-1cm past needle tip vs. 5-6cm past needle tip

Intervention Type PROCEDURE

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.
