Using the Adductor Magnus Plain Block As an Innovative Approach for Sciatic Nerve Block for Lower Limb Surgeries.

In the supine position, the femoral nerve block will be conducted using a high-frequency ultrasound probe to identify the femoral nerve just below the fascia iliaca. After proper sterilization, the needle will be advanced in-plane to inject 15 ml bupivacaine 0.5% around the nerve. After performing the femoral nerve block, the adductor magnus muscle plane block will be performed using a low-frequency ultrasound probe positioned 6 cm distal to the inguinal crease to identify the sartorius muscle, femoral artery, femoral vein, and femoral nerve on the deep side of the sartorius muscle, the probe will be slide by about 2-2.5 cm distally, where we could identify the plane between the adductor magnus and the semimembranosus muscles, and after proper sterilization, the needle will be slowly advanced until the needle tip is close to the posterior surface of the AMM, 20 mL of bupivacaine 0.5% will be injected while observing fluid distribution under the posterior surface of the AMM, Then GA.

While the patient is in the supine position, the femoral nerve block will be conducted using a high-frequency ultrasound probe to identify a cross-sectional view of the femoral nerve just below the fascia iliaca. After proper sterilization, the needle will be advanced in-plane to inject 15 ml bupivacaine 0.5% around the nerve. the patient will be turned on their sides with the operative side uppermost and flexed, the sub-gluteal sciatic nerve will be identified using a low-frequency probe, and then the same needle will be advanced the in-plane to inject 20 ml bupivacaine 0.5% around the nerve., then GA will be conducted as the other group
