A Comparison Of Block Quality In Anterior And Posterior Approach To Sciatic Nerve Block

A straight line along the femoral catheter was drawn between the anterior superior iliac spine and the finger palpating the pubic bone, the index finger was placed over the femoral artery pulse, a line was drawn perpendicular to the femoral fold. Over the pulse of the femoral artery, a point 4-5 cm lateral. The sciatic nerve was imaged by USG along the needle route and the needle was advanced to the nerve.

Patient was positioned laterally, with the limb to be blocked uppermost. The lower leg was straight extended and the upper extremity was bent 90° from the knee and was directed forward on the lower straight extended extremity. The patient's greater trochanter and posterior superior iliac spine were palpated and joined with a line, and a line was drawn 4 cm above the first line perpendicular to the caudal line. The USG probe was placed between the greater trochanter and the coccyx at the entry point of the needle and the needle was advanced by imaging the nerve.
