7.5ml femoral nerve

Details and patient eligibility

About

In modern anesthesiology, peripheral nerve blocks are performed using ultrasound control and electrical stimulation of peripheral nerves (PEN), or only ultrasound control or only EPN. The most effective methods are with the use of ultrasound control. Until now, the effectiveness of the femoral nerve blockade, performed only under ultrasound control without EPN, in comparison with the blockade of the femoral nerve performed under ultrasound control with EPN, has not been established.

There is no data on how the effectiveness of the blockade of the femoral nerve with small doses of lidocaine is influenced by the method of performing the blockade: under ultrasound control versus ultrasound control with electrostimulation of the nerve.

Research hypothesis: the blockade of the femoral nerve (7.5 ml 1%lidocaine -Minimum Effective Dose - previously established ) performed only under ultrasound control has the same effectiveness as the blockade performed under the ultrasound control with EPN.
