Femoral Nerve Blockade 7.5 ml of 1% Lidocaine: US Guidance Versus US Guidance With Electrical Stimulation of Peripheral Nerves (Influence of the Femoral Nerve Blockade on the Effectiveness of Small Doses of Local Anesthetic.). (EPBwEPN)
Femoral Nerve Blockade 7.5 ml of 1% Lidocaine: US Guidance Versus US Guidance With Electrical Stimulation of Peripheral Nerves
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.

Other: FN blockade under ultrasound control with a peripheral nerve stimulator 7.5 ml 1% lidocaine
Patients undergoing surgery on the shin, ankle or foot
|
Following the ultrasound visualization of the femoral nerve, a insulated injection needle was connected to the nerve stimulator . Under ultrasound visualization guidance, the needle of the electronic nerve stimulator was positioned at the femoral nerve (in plane) from its lateral side at a slightly superior position . A marker for LA introduction was the visualization of the needle end near the nerve, and a positive muscular response . Subsequently, the introduction of LA solution was initiated (7.5 ml 1% lidocaine).If LA was spreading from the lateral side down to the nerve, then the needle was replaced to the upper point of the nerve and the rest of LA was introduced, and vice versa . The presence of a complete and incomplete spread of LA along the entire circumference of the nerve was assessed. Correspondingly, if the anesthetic was spreading upwardly, the needle would be downwardly replaced. In addition, a sciatic nerve block is performed. |
Other: FN blockade under ultrasound control without a peripheral nerve stimulator 7.5 ml 1% lidocaine
Patients undergoing surgery on the shin, ankle or foot
|
Under ultrasound visualization guidance, the needle owas positioned at the femoral nerve (in plane) from its lateral side at a slightly superior position . A marker for LA introduction was the visualization of the needle end near the nerve. Subsequently, the introduction of LA solution was initiated. The position of the needle was corrected 1-2 times according to the type of anesthetic spread. If LA was spreading from the lateral side down to the nerve, then the needle was replaced to the upper point of the nerve and the rest of LA was introduced, and vice versa . The presence of a complete and incomplete spread of LA (7.5 ml 1% lidocaine) along the entire circumference of the nerve was assessed. Correspondingly, if the anesthetic was spreading upwardly, the needle would be downwardly replaced. In addition, a sciatic nerve block is performed. |
