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 PEN. The most effective methods are with the use of ultrasound control. Until now, the effectiveness of the sciatic nerve blockade by the subgluteal approach, performed only under ultrasound control without ESP, in comparison with the blockade of the sciatic nerve performed under ultrasound control with ESP, has not been established.

Research hypothesis: the blockade of the sciatic nerve by the subgluteal approach performed only under ultrasound control has the same effectiveness as the blockade performed under the ultrasound control with EPN.
