简要总结
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.

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)
