4 femoral block without EPN

Details and patient eligibility

About

There is little work comparing the effectiveness of a femoral nerve block performed only under US guidance or US plus electrical stimulation of the peripheral nerve (EPN). The authors have shown the same effectiveness of these techniques(1).But the effectiveness of the blockade of the femoral nerve (complete blockade) performed in different ways turned out to be low valve: 71.7% for ultrasound in combination with electrical stimulation versus 69% for only ultrasound guidance.

Research hypothesis: the blockade of the femoral nerve performed only under ultrasound control has the same effectiveness as the blockade performed under the ultrasound control with EPN.
