Approach to Continuous Sciatic Nerve Block for Orthopedic Procedures in Day Surgery With Two Different Techniques

Postoperative Pain Clinical Trial

Official title: Approach to Continuous Sciatic Nerve Block for Orthopedic Procedures in Day Surgery With Two Different Techniques

Status Completed

Clinical Trial Summary

We will enroll patients submitted to feet elective orthopaedic surgery that require analgesia through continuous peripheral nerve block (CNPB) of the sciatic nerve. All catheters will be placed by anaesthesiologists experienced in ultrasound in prone positioning. The patients will be randomized in two groups with technique of sealed envelopes.

In the tibial -peroneal nerve (TPN) group we will position the catheter within the confluence of peroneal and tibial nerve.

In the tibial nerve (TN) group we will proceed , previous local anaesthesia, to insert a catheter medially to tibial branch of the sciatic nerve according to in plane approach.

We will analyze A: the difference in consumption of local anesthetic in the two different groups B: the difference of "insensate limb" in the post-operative home as described by Ilfeld(inability to perceive the sense of touch throughout the area of distribution of the sciatic nerve) C: rate of foot drop D: numeric rate scale (NRS) for pain assessment, rate of dislodgment of the catheters, patient satisfaction, need for intervention by the anesthesiologist after discharge.
