Abstract:

U.S. high-risk patients in our study under the guidance of a low dose of LA in the surgical anesthesia was planned. ASA III patients as assessed by ultrasound guidance into the right femoral popliteal block by block, and both legs were provided surgical anesthesia. During the practice blocks with 80 mm-long needle and 10 ml of levobupivacaine 0.5% 10 ml of 2% lidocaine was performed by applying the block. Ultrasound guided femoral nerve be displayed, with the help nörostimülator right quadriceps muscle and motor responses after negative aspiration of 10 ml levobupivacaine 0.5% was applied. With ultrasound guided nerve blocks can be directly displayed as the success rate while improving the local anesthetic will also contribute to decreased. In the block under the guidance of ultrasound, a small amount of local anesthetic is allowing more than one block application
