Femoral Nerve detection using Sartorius Twitch
Procedure: Sartorius Muscle Twitch
Stimulation of the femoral nerve branch responsible for activating the Sartorius Muscle fascia with the lowest possible current.
Femoral Nerve detection using Quadriceps Twitch
Procedure: Quadriceps Muscle Twitch
Stimulation of the femoral nerve branch responsible for activating the Quadriceps Muscle fascia with the lowest possible current.
To determine if needle insertion at the inguinal crease with stimulation of sartorius muscle (anterior branch) causes an equivalent block to the classical method with stimulation of the quadriceps femoris muscle (posterior branch), for femoral nerve blockade. To test this hypothesis, we plan to conduct a randomised controlled double-blind study comparing success of femoral never block (motor and sensory) using sartorius twitch versus quadriceps femoris twitch as an end point.
We will also evaluate the local anesthetic distribution under the facia iliaca sheath using ultrasound imaging.
Methods: Following institutional ethical approval and obtaining written informed consent, we plan to recruit 60 patients aged 18-80, ASA I-III scheduled to undergo unilateral total knee arthroplastly in this prospective, randomised, double blinded controlled trial.
