简要总结
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.

结局指标
主要结局
Сomplete sensory femoral nerve block
时间窗: The quality of sensory blocks was assessed after 45 minutes of administration of the sciatic nerve block. The evaluation of the block was carried out by an anesthesiologist who was not involved in the study, and was blinded to solution that had been]
The stimulus of the needle prick was applied to check the sensory block of thefemoral nerve. The assessment of skin sensitivity was carried out with the help of a similar scale: + +\\ indicating a complete sensory block; +\\ indicating a partial sensory block, a patient was unable to differentiate between the type of stimuli ; and -\\ indicating that the skin sensitivity was fully preserved.
次要结局
- Сomplete motor femoral nerve block(The quality of motor blocks was assessed after 45 minutes of administration of the sciatic nerve block. The evaluation of the block was carried out by an anesthesiologist who was not involved in the study, and was blinded to solution that had been)
