Comparison of Two Techniques of Sciatic Nerve Block With Levobupivacaine 0.5% in Orthopedic Surgery

A proximal and distal initial scan and define the site to block the bifurcation. A puncture with an insulated needle guided by ultrasound and injection of levobupivacaine circumferential in 0.5% and a total volume of 20 mL.

A proximal and distal initial scan and define the sites to block: tibial and peroneal nerves separate distal 2 cm from the bifurcation site. A puncture with an insulated needle guided by ultrasound and injection of levobupivacaine circumferential in 0.5% 10 mL tibial nerve and 10 mL to the peroneal nerve.

Levobupivacaine is a local anesthetic that is commonly use for anesthesia nerve blockade.

An ultrasound machine is a device that is widely used for the correct placement of the local anesthetic for anesthesia nerve blockade.

This is a specific kind of needle that is widely used for anesthesia nerve blockade.

supplemental oxygen during the block and/or during surgery

Intravenous midazolam for sedation during the block and/or during surgery

Intraoperative administration intravenous of dipyrone 30-50 mg/Kg and or intravenous ketoprofen 100 mg or diclofenac 75 mg or ketorolac 30 mg

Depending on sensitive territory committed by the type of surgery suprapatellar saphenous nerve block guided by ultrasound with 100 mm Stimuplex needle and injection of levobupivacaine 0.5% (total volume: 5 ml).
