THE BLOCKADE OF THE SCIATIC NERVE BY SUBGLUTEAL AND POPLITEAL ACCESS PERFORMED UNDER ULTRASOUND GUIDANCE: COMPARISON OF TIME OF THE BLOCK DEVELOPMENT DEPENDING ON THE ACCESS

Purpose. The comparison of time needed for development of peripheral blockade of the sciatic nerve, made with 1 % lidocaine and adrenaline (1:200 000) under ultrasound guidance of the subgluteal and popliteal access. Material and methods. Patients were divided into two groups. In group A (20 patients), the blockade of the sciatic nerve was performed by the subgluteal access, in group B (20 patients) - by popliteal access. All the blockades of the sciatic nerve were performed with 30 ml of 1 % lidocaine with adrenaline (1:200 000) with the use of electrical stimulation of the peripheral nerves under control ultrasonic imaging. Results. In group A, the sciatic nerve sensory block developed in 15 (14, 16) minutes, the complete motor block developed in 15.5 (15, 17). In group B, the sensor block developed in 40 (38.5, 42.5) minutes, the complete motor block did not develop in any patients. Conclusion. The blockade of the sciatic nerve blockade with 1% lidocaine with adrenaline (1:200 000) under ultrasound guidance leads to faster development of thr subgluteal access sensor block than in its blockade of the popliteal access (15 (14, 16 ) vs. 40 minutes (38, 5 , 42.5 ) minutes, respectively.
