• Participant gender: All

Summary

In practice ambulatory orthopedic surgery, one of the problems of most difficult solution is adequate control of postoperative analgesia. Pain is a frequent cause of consultation and unscheduled readmissions in this group of patients.

The use of continuous peripheral nerve blocks are an effective tool in postoperative analgesia.

In this connection, most of the studies of continuous infusions of local anesthetics by perineural catheters have been made with bupivacaine, levobupivacaine, and ropivacaine However, it has been found that lidocaine action lasts less, has lower cost and is less toxic than longer-acting agents.

The investigators aim is to compare the effectiveness of lidocaine versus bupivacaine continuous popliteal sciatic blockade ambulatory elastomeric pump.
