COMPARISON OF THE EFFICACY OF ULTRASOUND-GUIDED BLOCKADE OF THE SCIATIC NERVE PERFORMED THROUGH THREE APPROACHES: GLUTEAL, SUBGLUTEAL AND POPLITEAL
ME "Mogilev Regional Hospital",

Objectives. Comparative assessment of the areas of sensory and motor block in blockade of the sciatic nerve, performed through three approaches: gluteal, subgluteal and popliteal.
Methods. In group A (n=31) the blockade was performed through the gluteal approach; in group B (n=193) – through the subgluteal access; in group C (n=32) – through the popliteal approach. All of the blockades of the sciatic nerve were performed with 30 ml of 1% lidocaine (epinephrine 1:200 000). Sensory block was evaluated in the foot, ankle joint, shin, popliteal fossa and posterior side of femur.
Results. In group A a complete motor block of the sciatic nerve occurred in all 31 patients. A complete sensor block was developed in all patients (100%) in the area of the foot, shin, popliteal fossa, posterior side of the thigh. Complete motor blockade of the sciatic nerve was obtained in all patients in the area of the foot, shin, popliteal fossa, posterior side of the thigh. In group B a complete sensor block in the area of the foot, shin occurred in all patients. In the popliteal fossa area a complete sensory block developed in no patient, a partial block occurred in 143 patients (74,8%) and in 50 patients (25,2%) the sensor block didn’t developed at all. In group B a sensor block in the lower, middle and upper third of the thigh developed in no patient. In group C a complete sensory block in all 32 patients developed only in the area of the foot, ankle joint and lower third of the thigh. Complete motor block wasn’t registered in any patient.
Conclusion. When the sciatic nerve is blocked by the subgluteal approach, the complete sensor block doesn’t develop in the popliteal fossa and posterior side of the thigh. Using the popliteal approach, the sensor block occurs only in the area of the foot, ankle joint and lower third of the tibia. When the sciatic nerve is blocked through the gluteal approach, the sensor block develops in the area of the foot, shin, popliteal fossa and lower third of the tibia.
