研究概览
简要总结
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.
详细描述
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.

研究组 & 干预措施
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.
干预措施: Sciatic catheter left 0-1cm past needle tip vs. 5-6cm past needle tip (Procedure)
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.
干预措施: Sciatic catheter left 0-1cm past needle tip vs. 5-6cm past needle tip (Procedure)
结局指标
主要结局
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).
时间窗: Day 1 after surgery, 3 hours prior to phone call
