Study Details

Brief summary:

In this study, we will be comparing two approaches to the femoral block. The first or classical approach and one that is the most popular in our institution is used by combining ultrasound guidance and neurostimulator to do the block. The second is performed with the ultrasound alone aiming at the inferolateral aspect of the femoral artery with the needle and injecting. The primary endpoint of the study is the sensitive cutaneous block distribution using both techniques.

Interventions and Outcome Measures

Arms

active comparator: Femoral nerve block using Ultrasound and neurostimulator

Femoral block using the standard technique of ultrasound for femoral nerve identification and neurostimulator set at between 0.3-0.5 mA with quads muscle response for needle placement confirmation before injecting 20cc of Ropivacaine 0.5%.

experimental: Femoral nerve block using femoral artery target

Femoral block using the alternate technique of aiming for the inferolateral aspect of the femoral artery and injecting 20cc of Ropivacaine 0.5%.

Interventions

Femoral nerve block using Ultrasound and neurostimulator

Femoral nerve block using Ultrasound

Ropivacaine 0.5%

Ropivacaine 0.5% (20cc total) will be injected for the performance of the block in the two arms of the study.

Primary outcome measure

  • Sensitive cutaneous block distribution area for the two techniques [ Time Frame: 45 minutes ]
