MINIMUM REQUIRED AMOUNT OF THE LOCAL ANESTHETIC (LIDOCAINE) DETERMINATION TO PROVIDE EFFECTIVE AND SAFE SCIATIC NERVE BLOCKADE
Objectives. To determine the minimal amount and quantity of lidocaine necessary to provide effective sciatic nerve blockade.
Methods. 193 sciatic nerve blockades were performed in 193 patients under ultra-sound visualization control with the application of the electrostimulator of the peripheral nerves. Blockages were done using lidocaine: 0,75% – 20 and 15 ml; 1% – 40, 30, 25, 20, 15, 12,5, 10 ml; 1,5% – 10 and 7,5 ml, 2% – 10, 7,5 and 6,5 ml, 3% – 6,5 5, 4,5 ml, 4% – 5 and 4,5ml.
Results. Minimal amount of 0,75% solution at which the complete sciatic nerve blockade was reached was 20 ml; 1% – 12,5ml; 1,5% – 10ml; 2% – 6,5ml; 3% – 5ml; 4% – 5ml.
Conclusions. Minimal amount of the local anesthetic solution at which an effective blockade of the sciatic nerve can be obtained is 5 ml and minimal lidocaine amount is 125 mg.
