简要总结
Research study to determine the relationship between perineural catheter tip location relative to the sciatic nerve bifurcation and postoperative analgesia for continuous popliteal nerve blocks.
详细描述
Hypothesis
During a continuous popliteal nerve block, postoperative analgesia will be improved with the perineural catheter tip at the level of the sciatic nerve bifurcation compared to when the catheter tip is 5 cm cephalad/proximal to the bifurcation.

研究组 & 干预措施
At Bifurcation
Patients randomized to this group will receive a sciatic nerve block placed at the bifurcaton of the sciatic nerve and outcome measures will be tested.
干预措施: Catheter Placed At Bifurcation (Procedure)
5cm Above Bifurcation
Patients randomized to this group will receive a sciatic nerve block placed 5cm above the bifurcaton of the sciatic nerve and outcome measures will be tested.
干预措施: Catheter Placed 5cm Above Bifurcation (Procedure)
